Coding an Advent Calendar: Day 13

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 13

Add JS handlers for “Today”
“Today” I didn’t have tons of time to put in to work on this project. So, I chose some of the “low hanging fruit” to work on – to make meaningful progress with small(er) modifications.

One of these “low hanging fruit” was adding JavaScript handlers for properly displaying the proper packages based on the current date. Here’s the procedure:

  1. Use .getDate() from the JavaScript Date object to get the numeric date for today
  2. Use jQuery selectors to grab the page elements that need manipulated accordingly
  3. Use conditionals to determine which classes or CSS to apply to each (particularly the Font Awesome gifts in the footer – as each can have 3 “states”)
    1. "active" = green/red package
    2. "today" = highlighted (darker) and scaled (larger)
    3. "disabled" = grayed out
  4. Also, use jQuery .unbind('click') on any "disabled" footer packages to prevent clicking (and peeking at presents before the time has come)
Better styling of REST Posts
Another of the “low hanging fruits” I decided to tackle today was the styling of the WordPress Posts called in with the REST API. This is particularly important for the responsiveness of this design as leaving the Posts underneath the large Gift box on smaller screens would crowd the screen.

I decided to make the WordPress Posts pop up on an “overlay” or “lightbox” style screen (as the Featured Image above shows) when the Gift is clicked on. Here are the steps I took to do this as well as thoughts for its further development:

  1. Make the React Component #posts container act as the overlay (with dark blue background)
  2. Add an extra <div className="inner"> in React to surround each Post’s content
  3. Query the WP REST API for 25 Posts (with per_page=25)
  4. Make the #posts container pushed off the page 100% to the bottom so that when the Gift is clicked, I apply a CSS animation to ease-in the top-margin back to 0 (which makes the #posts container slide in from the bottom
  5. Make the entire dark blue background of the #posts container clickable – to rehide the container at the bottom of the page (slide down)

Notes for future development:

Although I’d originally considered just having React dynamically “react” to clicks on various boxes to display ONLY the Post from that date, I’m now considering styling #posts in the same way as the Gift boxes #carousel:

  1. allow each Gift to take up the full width and height of the visible page area
  2. allow each Post to take up the full width and height of the invisible page area to the bottom of the screen

This would easily line up both the Gift box and the Post for its date one on top of the other, so that when the Gift box is clicked and the #posts container animates upward, ONLY the Post for that date would be visible. This would also give me a little more freedom about how to style each Post individually.

One more consideration I’d made is how I might use React to ONLY (dynamically) load 3 Posts at once:

  1. The currently selected Post (defaults to "today")
  2. The previous Post and dated Gift
  3. The next Post and dated Gift

This would allow both the Gift #carousel and the #posts containers to reduce their maximum necessary width to only 3 screen-lengths (instead of 25 screen-lengths) and therefore also probably reduce the “bugginess” that’s currently affecting my Carousel (about 5px extra left margin on EVERY subsequent date for some reason – which adds up to a HUGE space by the time Christmas comes).

But, I haven’t yet worked out how to do that with my limited knowledge of React.js and Components – and that’s what led me to the third step for today ↓

Begin Ray Villalobos React Course
I decided to head back over to Lynda.com to try to learn some more about React. There aren’t actually that many React courses on Lynda.com YET, but the one that looked most helpful for the kinds of ways I’m considering using React in this project was Ray Villalobos’ React Course:

Building a Web Interface with React.js

I’m looking forward to learning much more through this Course that I can put into practice in my Advent Calendar. PLUS, as I am able to use create-react-app on my Windows PC but not getstorybook, it will allow me to continue (branched) development both at work (Windows) and at home (Mac).

Coding an Advent Calendar: Day 12

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 12

Storybook on Windows (FAIL)
So, after some good work on React Components in Storybook on my Mac over the weekend, it was back to the office on Monday – and my Windows computer.

Last week, I’d had trouble setting up Storybook on the Windows computer – it kept giving me a sh: start-storybook: command not found error. I found two GitHub issues that were similar to my problem:

  1. ERR! on npm run storybook
  2. sh: start-storybook: command not found

and quickly read through the discussions there to see if I could fix my installation. It didn’t work.

Then, I tried a completely fresh installation of both create-react-app (successful) and getstorybook (less so) to see if that wouldn’t solve the problem and get me up and running on Windows. It didn’t. I got the same errors as before, so that seems to indicate that there may be some compatibility issues with Windows – or maybe I just screwed up something in my system setup from the start.

Well, rather than give this issue any more time (I’d already spent 1-2 hours on it), I decided to move back over to my Codepen version of the site and continue working on some CSS styling.

Continue styling <Tag> Components
As the Featured Image for this Post shows, I decided to continue working on the Tag (and other) CSS since Windows was being picky about my React Storybook configuration.

As far as the Tags go, currently they are CSS shapes, although I feel like there may be some limitations in how I want to handle interactivity with them as CSS shapes. For example: the Tags are currently styled like so:

  1. A <div> box that contains the main text
  2. A div:before that creates the triangular portion of the tag
  3. A div:after that creates the rear Pac-man portion of the tag

So, technically, the Tag is 3 individual pieces as a CSS shape, so doing something like “flipping” it over to read the back (as I’ve done with a sample Lynda.com flip cards menu here) doesn’t seem like it will be very easy. So, I’ve considered two other options:

  1. Create an SVG shape for the Tag (a single item)
  2. Change how I show interactivity – like having some sort of “Christmas-y magic sparkle animation” flow over the To: text before displaying the From: text (and vice versa)

In addition to styling the Tags with CSS, I also added a "disabled" class to all the “gift boxes” in the footer whose dates have not yet come. Ideally, these will be linked up to the big (tagged) gifts and will be controlled by JavaScript (jQuery or React – whichever I work out) to change the date as the countdown clock changes. (i.e. when the clock reads 00:00:01 second remaining for a day, then flips over to the next day, ideally, the "active" Gift would also change.)

Also, the "disabled" tag should prevent users from being able to click on any of those Gifts to view their days “in advance” (and scrolling to dates later than the present date should also be disallowed).

Begin Responsive Styles
Finally, I decided to work on Responsive styling a little bit since the computer I did most of this coding work on in the afternoon had a screen resolution of 1024x768px (and at that size the whole Codepen looked pretty ugly). The following are some of the considerations I need to make when making this site responsive:

  1. Gifts in the footer
    1. Reduce the font size (DONE)
    2. or make the footer scrollable,
    3. or only display only the a few gifts (like some WordPress paging menus with [Prev] ... [12] [13] [14] ... [Next] buttons)
  2. Big gifts
    1. Reduce the size on smaller screens
    2. or scale them smaller
    3. and/or remove/reposition the Tag
  3. Countdown clock
    1. Reduce the size
    2. or stack it vertically to the left or right of the gift
    3. or divide it in two and stack half vertically to the left, half to the right
    4. or remove much of the styling (including the background circles) and turn it into a kind of smaller “digital clock” (as opposed to analog)
  4. Header and top menu
    1. Reduce font size and height (DONE)
    2. Also use a “hamburger” style menu button at very small sizes
  5. React-loading Blog Posts
    1. Still need to figure out how I want these styled initially anyway (title only, title and excerpt, or what) – after that we can figure out responsive styling

Coding an Advent Calendar: Day 11

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 11

Begin separating out CSS per Component
The way this create-react-app with Webpack configuration works is that in each ReactJS Component, I need to import the other Components and files that each depends on. For example: import React from 'react' is the first command at the top of every Component in order to load in the ReactJS library to build my Components. The same is true for CSS files.

So, rather than calling import './App.css' in every single file and controlling them all with a single stylesheet, I started breaking the main stylesheet down into separate files that handle each Component individually. In other words, my folder structure went from this:

/js
 |- GiftIcon.js
 |- Gift.js
 |- Tag.js
 |- BlogPost.js
 |- Scene.js
App.css

To this:

/js
 |- GiftIcon.js
 |- Gift.js
 |- Tag.js
 |- BlogPost.js
 |- Scene.js
/css
 |- GiftIcon.css
 |- Gift.css
 |- Tag.css
 |- BlogPost.css
 |- Scene.css
App.css

In some ways, this will now work in a similar manner that my previous Sass configuration was setup to work as. Basically, I wanted to use Sass to subdivide out all the various Component’s CSS into separate files (for easier file management) and then let the Grunt compile them all back together into my main style.css file that would be used by the site.

The only caveat is that I can no longer use Sass variables and mixins (as it stands now). This may or may not prove to be a “deal breaker.” I honestly love the way Sass makes it easy to manage variables (like brand colors or font-stacks) and mixins (like specific component styles – say, buttons, form elements, or boxes of content).

Attempt to load in static files & Sass
There may yet be a way to get Sass back into my project – and I’ll continue investigating this as time goes on. For now, I attempted two solutions to load in static files (like Google Font links) and add Sass back in. Both seem to have not worked as intended, but I may have missed something in the configuration:

  1. Custom Webpack config
    1. This is supposed to help get Sass back into the project. The webpage states: Once you create this webpack.config.js file, Storybook won’t load the default Webpack config other than loading JS files with the Babel loader.
  2. Add Custom Head tags
    1. The instructions here are to create a head.html file that resides inside the Storybook config directory and should inject these tags to the iframe where your components are rendered.
    2. Google Fonts: However, I couldn’t get Google Font links to work immediately, so I’ll need to do some more investigation about that. For now, I’ve just added those with an @import command at the top of my stylesheets.
    3. Font Awesome: I’ve also stored the Font Awesome files and CSS in project directory and used another @import command to load in Font Awesome.
Begin coding a Tag for the Gifts  

While working through the Learn React.js: The Basics videos, there were some that demostrated how to create interactive Components (the project in that Course was to create a Bulletin Board filled with Post-it Notes). So, in a similar vein, I decided to add Gift Tags to the Gifts that would allow users to address them and either Save the names entered onto the Tags, or possibly “Send” them via email or social network. Here’s the plan so far:

  1. Each Gift Component has either a) no tag with the option to add one, or b) an unaddressed, empty tag
  2. The Tag Component can be addressed with a To: and From: address
  3. On :hover, the Tag will flip over to reveal From: (it will show To: on the front by default)
  4. To: will provide space for a name, and an optional email address (or possibly social network URL)
  5. From: will default to “Santa Clause” or “Saint Nick” or “St. Nicholas” (assigned at random), but can be modified and saved
  6. Each Tag will (maybe) contain social network buttons (Facebook, Twitter, and Email primarily) to which users can send that particular (Gift – i.e. Blog Post)

I haven’t yet worked out HOW the sending of Blog Posts should be handled with the Tag Component, but so far, this is the roadmap and “ideal” plan.

Coding an Advent Calendar: Day 10

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 10

Finish Lynda.com videos
Today I finished the Lynda.com Course Learn React.js: The Basics. Here are a few of the biggest takeaways from the Course:

  1. React IS actually incredibly fast
  2. React syntax may be new (to me) but doesn’t feel unfamiliar (it’s a kind of XML)
  3. React sites are built with React Components (each with props and state)
  4. Each React Component has a “lifecycle” (mounting, updating, and unmounting)
  5. React Components can utilize parent-child relationships
Get all React Components working
After a bit of debugging and editing, I was able to get (my version of) each of the React Components in the Lynda.com Course working – including in Storybook. I’ve also updated by public Gist on the basics to include correct syntax and comments.

I noticed two of my most common errors in my original React syntax were:

  1. If you want to string together functions separated by commas, like an Object (i.e. getInitialState() {...}, componentWillMount() {...}, render() {...}, then you MUST use the React Native syntax (var MyComponent = React.createClass() {...}) and NOT ES6 syntax nor the stateless functional syntax.
  2. For some reason, I’d accidentally had an extra closing curly bracket } after my render() function – this was producing the “horrible error message” I mentioned yesterday. But at least now I learned what to look for the next time.

Begin creating a Christmas Scene  
Finally, I started putting everything together into a kind of Christmas “scene” (as evidenced by the Featured Image on this Post). I DEFINITELY feel like React is useful for creating parent-child relationships between Components and for allowing me to dynamically create, add, or remove Components based on the code.

For example, the image above was created using code for Scene.js (the parent Component) and Gift.js (the child Component). Scene.js called Gift.js 25 times and looped through it to create 25 separate Components – each with its own unique ID and properties. This will definitely prove to be useful when I start looking into pulling in blog Posts from WordPress using the WP REST API.

Coding an Advent Calendar: Day 9 (5 React Configurations)

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 9

create-react-app
Yesterday I was having some trouble with my React code functioning properly with the in-browser Babel compilation. Notably, I kept running into this error:

which clearly isn’t very helpful for debugging my code.

For one thing, sometimes the error message seemed to point to an empty line! I’d read on StackOverflow (somewhere) that perhaps that indicated the error was actually in the line ABOVE it, but it wasn’t. And I still couldn’t find where there was a problem no matter how much I looked, nor how many times I rewrote the code.

Finally I decided enough was enough and I was going to have to include Babel and all the other dependencies inside my project to compile everything there, rather than continuing to import Babel via CDN and try to compile in the browser. I figured if nothing else, at least I’d get some better error messages with code that was pre-compiled before being loaded by the browser.

So, on the suggestion of the Lynda.com video series I’ve been watching, I decided to create a totally NEW folder and install create-react-app via npm to help out.

npm install -g create-react-app
create-react-app advent-calendar
cd advent-calendar
npm start

Fortunately, after installing it and running the npm start process to watch and compile my files, I was immediately greeted with a MUCH more helpful big, bold, and beautiful (descriptive) full-screen error message:

This allowed me to properly diagnose my problems, debug the code, and get everything running smoothly. At first.

React Storybook
Actually, the FOUR setups I tried are very different:

  1. React + Axios in a Codepen
    1. Incredibly painless as all the configuration is provided by Codepen
    2. Easy to get started due to the number and quality of samples available
    3. Only requires linking to some scripts (react.js and axios.js) and enabling Babel as your JS preprocessor
    4. DOESN’T actually teach you a lot about how to set these technologies up and use them in a real-world project
  2. React + Babel + Grunt
    1. It requires a complete manual setup (installing everything you want via npm)
    2. More difficult for a first attempt to get everything configured properly
    3. But allows more precise control over exactly what you include in the project
  3. React and Babel via CDN
    1. It’s as simple as copying in a few URLs as <link> tags
    2. Easy to get started, but provides horrible error messages that are little help
    3. Requires NO node modules nor unique file/folder structure – you could build everything out as a regular static page (index.html, style.css, and React scripts before the closing <body> tag)
  4. React with create-react-app and webpack
    1. Super easy installation and process to get things up and running via npm (see code snippet above)
    2. Much more helpful error messages (like the one in black above) that can help you easily diagnose and fix problems with your code
    3. Includes TONS of node modules – many of which you may never need
    4. Requires its own file/folder structure that may be confusing at first (all your .css files and React components are abstracted out into a /src folder that will be compiled into .css and .js files with a hash string appended to the end like a version number (app.d587bbd6e38337f5accd.js) and put in the /public folder when you do npm run build to get it ready for deployment)
    5. Requires digging deeper into more technologies you may or may not have ever heard of before. For example, for me, I’ve only now ever HEARD of:
      1. webpack
      2. flux
      3. redux
      4. storybook

I haven’t even visited the websites for webpack, flux, or redux yet, but storybook instantly had me interested because of what it allows you to do: “Developing Components in Isolation.” I knew immediately that this was something I’d want to try – since I have multiple Components I will be developing:

  • First of all, Test Components to help learn React better
  • Secondly, a Gift Component for my CSS gift shapes
  • Also, a Post Component for blog posts loaded with the WP REST API
  • Possibly also other Christmas Components – like a Santa, or tree, or reindeer

So, I set about the work of figuring out how to get Storybook up and running (for my 5th React setup). A few things I noticed about Storybook:

  1. React + Storybook
    1. create-react-app uses npm start to run a server though port :3000
    2. Storybook defaults to run a server through either port :9001 or :9009
    3. Adding static .css or .js files can be a pain because of the configuration and how Storybook compiles things. There are really only two ways to do it:
      1. Add Custom <head> tags
      2. Serve static files via imports or a directory
      3. I ended up just using the CSS @import rule to load my Google Fonts
    4. Storybook was designed to develop Components in isolation – and it’s really a great way to perfect individual parts before putting them all together again in the main App
    5. Adding in additional Stories is pretty straightforward once you get through the configuration
Update npm and node and figure out git  
One of my biggest issues throughout developing this project has been that I have two completely different setups to work with throughout the day:

  1. At work: Windows 7
  2. At home: MacOS

That means that no matter where I go, for half the day at least, my configuration is going to be totally different. So, whenever I spend a few hours in one location learning how to setup and configure some part of my setup, I must then (at least partially) repeat that process in the other location later that day. It can be a little monotonous, but honestly the repetition is probably really good for my learning (that, and blogging about it).

Three things that seem like they may be larger “speed bumps” than they probably should be are: npm, node, and git

  1. At work: after installing create-react-app and the various other parts I needed, I kept noticing that the Command Line was prompting me with warnings about my (outdated) versions of npm and node. I didn’t really think much of it, but noticed that the installation of those modules took significant time (I ate lunch during the process)
  2. At home: When I came home later in the evening, I started getting the same errors, but again thought nothing of it – until my Mac froze up (it happens sometimes when I have a bunch of programs and Chrome tabs open and I haven’t shut down in a month…) So, after restarting the Mac, I decided to immediately update npm and node and WOW! what a difference that made! The installation of create-react-app and the Node modules FLEW compared to earlier. Below is the series of (Mac) commands I used in the Terminal to update them:
npm install npm@latest -g
sudo npm cache clean -f
sudo npm install -g n
sudo n stable

Finally, git. At first, I was worried that with the two different setups on the two different systems that git would prove to be problematic. I was worried that I might have to either memorize the differences in files and setup between Windows and Mac, or create two separate package.json and other relevant files.

However, after looking over the config files from both my Windows and Mac setups (I set up two completely different folders with the files from each system), I no longer think that’s the case. They look nearly identical and a few minor version number changes in the dependencies won’t really matter (down a version number).

So… Day 9 was a LONG day (which is why this blog post is long – and why I’m “technically” publishing it on Day 10), but it was a good day – not entirely productive in code, but very helpful in my learning more about React and how to work with it.

Today, I’m planning to finish React.js: The Basics on Lynda.com, create some new Components, possibly add in Sass (again) to my create-react-app project, and possibly add some interactivity to my Christmas Gift Component. Stay tuned!~

Coding an Advent Calendar: Day 8

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 8

Use React and Babel via CDN
Since yesterday I was unable to get React and Babel fully working on my stand-alone localhost site, I decided to take a step backward today and try to get a clearer understanding of what was required to do so. Therefore, I started watching:

Learn React.js: The Basics on Lynda.com

I decided to take a slow, step-by-step approach to learning React from the ground up, which meant one of the first steps I did was load in React and Babel via CDN:

  • React: https://unpkg.com/react@15/dist/react.js
  • ReactDOM: https://unpkg.com/react-dom@15/dist/react-dom.js
  • Babel: https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.38/browser.min.js (the author states that Babel 6.0 and above won’t work as in-browser compilers)

This allowed me to at least start getting my site to render without JavaScript syntax errors.

Install React developer Tools for Chrome
After loading React and Babel, I also found it helpful to install the 2 React developer tools to Chrome that Eve Porcello mentioned on the Lynda videos:

  1. React Detector: detects whether a website is using React or not, and lights up bright blue if so (install it, and then visit AirBnB to see it working)
  2. React Developer Tools: adds an additional tab labeled “React” to the F12 Chrome Developer Tools and allows you to view React Components and debug things in the browser


I found both of these to be very helpful tools.

Create very basic React.js pages  
Finally, as I began working through the Lynda.com videos, I thought about how I might apply the concepts to my own Advent Calendar project.

I also created a public Gist on GitHub to house my work.

Then, I started testing the various iterations of my project (still needs more testing) in a separate standalone HTML file in my localhost. The screenshot above is a result of this work.

I can see there is still a lot to learn about React, but so far it’s been quite interesting. It’s very speedy, incredibly versatile, and the syntax is pretty straightforward. I’ll continue on this journey tomorrow.

Coding an Advent Calendar: Day 7 (REST API + ReactJS)

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 7

WordPress 4.7 “Vaughan”

WP REST API!!
Today is the big day! WordPress 4.7 launched this morning (in Korea) with the WordPress REST API content endpoints included in core (and a pretty great updated REST API Developer Reference as well). So… you know what that means. Today is the day I get the Advent Calendar to pull my blog posts with the (core) WP REST API! There are X steps:

  1. Revisit Day 2 where I set up the basic infrastructure for ReactJS & REST
  2. Update to WordPress 4.7 – where REST endpoints will work immediately (cool)
  3. Install Postman for Chrome* to test calls to the REST API
  4. Configure the REST URL (I have mine pull from THIS Category)
  5. Add it to the Codepen
  6. Watch the magic happen!! (…almost)

*Side note: Be sure to get Postman’s output as JSON for an easier view.

React Component
Actually, I hadn’t already created my React function to render the retrieved Component. I’d only filled in a blank <div> as a placeholder. So, the next step was to create an HTML structure in the React class that would receive the array of Posts from my REST API query and render them to the page.

Then, I added some basic CSS styling to make them look a little better on the page after loading.

BabelJS  
Finally, after setting everything up and Saving the Codepen, I noticed a small error in my JavaScript console in Chrome: "Unexpected token <". That’s weird, I thought. But then I noticed that the color highlighting in the Codepen was incorrect after a certain point – and the posts from React weren’t displaying quite properly. I checked back at the other Codepens I’d referenced that were using React to load JSON data and noticed that many were using the Babel JavaScript preprocessor. I thought, what the heck, added it to my project and *BAM!* the magic truly DID begin! Smooth loading of posts on the Codepen directly from this blog!

But… that’s Codepen. If I wanted to continue local development, it wasn’t going to be nearly so easy as that. I’d never heard of BabelJS before this, so I started investigating it and found out that it is often used with React and other scripts to create modern JS like ES2016. I realized I’d need to install the Node Modules for React, Babel, and Grunt to run all of these together, so my research and work began. There were X steps to complete this process:

  1. Run npm install --save-dev babel-cli babel-preset-latest babel-preset-react grunt-babel to install all the necessary development dependencies
  2. Run npm install --save react react-dom to save the necessary project dependencies
  3. Update package.json to recognize babel (rather than creating a .babelrc file)
  4. Update Gruntfile.js to “watch” for changes to my React app’s JS file and run the compile task
  5. Separate out my React Component code from the functions.js file to better manage the two separately
  6. Also, include React and React-DOM in the React app’s JS file

So far, I’ve been able to get Grunt to successfully “watch” for changes to my Sass files and my ReactJS files and run their compilation tasks. But, now I’m getting an Uncaught ReferenceError: require is not defined(...) error. Well, looks like fixing this is on the schedule for tomorrow!~

References

The following are some React and BabelJS references I was perusing today as I tried to get things to work. I haven’t finished reading through all of them yet:

  1. Official React site: A JavaScript Library for Building User Interfaces
  2. Writing React components as CommonJS modules
  3. NPM: A RequireJS plugin for loading jsx in require.js and r.js
  4. The React.js Way: Getting Started Tutorial

  7. Get To Know Babel The JavaScript Compiler Tutorial
  8. Setting up an ES6 Project Using Babel and Browserify
  9. Babel + Grunt === ES6 Now!
  10. ES6 with Babel & Grunt

Additionally, I just stumbled across a Lynda.com video that addresses using BabelJS to compile React. In this video, Eve Porcello shows how you can do in-browser Babel compilation by importing the script via a CDN, then using <script type="text/babel"> tags around any code you want compiled by Babel.

She does note that in-browser compilation is slow – and shouldn’t be used in a production environment. So, it’s good that I’ve started getting Babel set up as a module to precompile my JS before using it in the webpage.

Coding an Advent Calendar: Day 6

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 6

Add README.md
Actually, part of Day 5’s work of setting up Grunt, Sass, and Autoprefixer* for development carried over into Day 6. So, I did little more coding and more work on the overall project housed on GitHub. Part of this work included adding a README file that would stand as the GitHub project’s “front page”. There are at least 3 things I like to include in GitHub README files:

  1. A main project image (and possibly some other images)
  2. A description of the project: what it is and how to use it
  3. A Changelog that shows the various updates to the project over time (I have considered adding this as a separate CHANGELOG.md file, but decided for the time being to leave it in my “front page” README.md)

*Actually, Autoprefixer is now deprecated in favor of grunt-postcss so I will probably take some time to set that up later as well.

Add a GitHub Issue for Images
Adding an image to a GitHub README is relatively easy: all you need is a link to an image that already resides online. You can add this with a ! in front of the image link:

![day4](https://cloud.githubusercontent.com/assets/6644259/20913450/5ac0b6d8-bbbb-11e6-9a82-2d8eed8abb9f.png)

However, if you do not HAVE an image online yet, and you were intending to use an image directly from the GitHub repository itself, you may run into some trouble because you can’t just “Upload Image” anywhere easily. But there is one easy “hack” I stumbled across online some time ago that I’ve been using for a while:

  1. Create a GitHub Issue and upload an image there. GitHub will let you drag and drop an image from your desktop into the Issue reporter textarea, and from there you can grab the link to the uploaded image to use in your README.

This could be a little “messy” because now you will always have at least 1 Issue open for that repository (unless you move your image link offsite), but it works. (I’d tried to do the same thing with GitHub’s Wiki for the repository, but it also won’t allow you to upload an image. Rather it requests the Image URL.)

Add LICENSE  
Finally, I decided to add a LICENSE to the repository.

Since I’ve been developing WordPress stuff for many years now, I’ve come to know and enjoy the GPL license quite a bit. But, I didn’t know if I wanted to just go with that right off the bat, or if perhaps there was something else I might choose. So, I started investigating things and stumbled upon an excellent website that let me compare the different Open Source licenses easily. I considered two choices:

gpl-license mit-license

I decided to use the MIT License as it seemed to be a little simpler and had less Conditions.

*Side note: After getting my first WordPress theme approved for the WordPress.org Theme Directory, I realized how important keeping track of the resources you use in a project is. Before approval, I needed to list all the projects, sources, and licenses of every additional piece of software or code I used in my theme (like any Google Fonts I used, FontAwesome, the Foundation Framework, and so on). This is something I may decide is important to do for this project as well.

Coding an Advent Calendar: Day 5 (Maintenance)

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 5: Maintenance

GitHub Repository
After coding for 1-2 hours each day for 4 days, I found my code getting quite long:

  1. HTML: 344 lines
  2. SCSS: 602 lines
  3. JS: 187 lines

This quickly starts to become a lot to manage within a Codepen – given that the 3 editors are all small boxes to the side of the screen. I prefer to work on bigger projects in a good code editor like Atom or Brackets (I use Netbeans for really big projects like WordPress themes or plugins). So, I decided it was a good time to upgrade the project to “bigger” and continue development primarily in Atom (which has a convenient Live Server package that really aids in development).

I’ll continue to update the Codepen with my code updates – at least for now.

Setup a Grunt Taskrunner
Codepens are nice in that the Sass, or Less, or PostCSS is instantly compiled and usable as CSS as soon as you write it. But, things don’t work like that in stand-alone projects. So my first step after pulling my files from Codepen and creating a GitHub repository for them was to start preparing to use Grunt.js as a taskrunner to watch and compile my Sass into web-browser-readable CSS. Here are the steps I took (which will be outlined in further detail in a later post):

  1. In the global environment
    1. Install Node.js (Windows)
    2. Install Ruby (Windows)
    3. Install Sass: gem install sass
    4. Install Grunt-cli: npm install -g grunt-cli
  2. In the project folder
    1. git init, commit, and push to remote repository
    2. npm init to setup package.json which keeps track of dependencies
    3. npm install grunt-contrib-sass --save-dev installs the package locally (without --save-dev it would be a global installation)
    4. npm install grunt-contrib-watch --save-dev
    5. npm install grunt-autoprefixer --save-dev to autoprefix the CSS
    6. Create the Gruntfile.js that controls grunt and the Sass file compilation
    7. Run grunt from the command line (in my project folder) to start the taskrunner and allow me to modify my Sass files (CTRL + C ends the taskrunner)

For more information on this process, check out Morten Rand-Hendriksen’s helpful Course @Lynda.com:

WordPress: Developing with Sass and Grunt.js

Begin blogging  
Finally, in order to begin attempting to get the WP-API running well on this site, I needed some content on a WordPress site to begin pulling from – hence the creation of this series of blog posts.

As mentioned previously, I’m also hoping to create a 25-day series for Advent that highlights my favorite typefaces. The goal is to allow users to switch the series of posts that the REST API pulls from. They’d be able to either load the “Coding an Advent Calendar” series, or the “Advent Typography” series.

Coding an Advent Calendar: Day 4

This year, I decided to create an Advent Calendar website in HTML5, CSS3, and JavaScript. My hopes for the site are to showcase some of my frontend development abilities as well as make something fun, functional, and reusable.

Day 4

JavaScript Countdown clock with SVGs
After browsing some other Codepens tagged "advent", and "calendar", and "clock", I decided to add a countdown clock to my calendar. I had a few ideas:

  1. Make SVG presents that would get filled to a higher percentage as the time toward Christmas approached (like a fund-raising campaign’s thermometer)
  2. Make SVG circles that filled in a clockwise manner – as a countUP to Christmas (Christmas Day would show all four circles as fully filled)
  3. Do the traditional countDOWN clock, making the SVGs reduce their fill percentage as the time went on

I settled on #3 and used CSS-Tricks.com’s How to Make Charts with SVG post and Codepen to help create the clocks (I borrowed the code from Chris Johnson’s Codepen which uses jQuery Easing to switch the numbers). I also made the stroke-dasharray (basically, the circle’s border) value equal the full radius of the circle. This makes it look more like a pie chart or clock hand that extends outward from the center of the clock.

Assign Year text dynamically
Using JavaScript’s built-in Date() class, I made JS retrieve the current year and write that text to the page in the “Remaining ’til Christmas …” heading (I’d also originally placed it in the “Advent Calendar” heading as well, but thought it was too much). I then build the FULL JavaScript date using the current year’s value and pass THAT into the countdown clock function.

Thus, theoretically, the clock should start all over again on January 1 EACH year with a value of 358 or so days. I guess we’ll see in about a month~~

CSS-only slider  
The next step was to create a slider that would literally “slide” through the daily presents as I clicked on the available ones, or the “previous” and “next” arrows. Again, I looked at many CSS sliders on Codepen, and used one as inspiration to help make my slider functional as well.

The only problem was that, for some reason, something in my CSS or design was causing each “slide” to be offset an extra 5px to the right. I’d used 100% (or even 100vw) width for the slides – which was 1089px at that time. Yet, when I scrolled to the following slide, the offset was 1094px – and this kept up for ALL 25 days! (Needless to say, that was a pretty noticable mistake by the time Christmas came ’round.)

So, this is an area that will need to be revisited. I have 3 options so far:

  1. Use Bootstrap: except I haven’t yet used it, so it messes up some of my CSS when I import those CSS styles – and I don’t want to depend on it for everything
  2. Use hidden input radio buttons: I’ve seen this done in some other sliders and it looks like it might provide a good option
  3. Use JavaScript: Obviously, JavaScript would give me a little more control over ALL the pieces of this slider (like the presents underneath, and the “previous/next” buttons) – so I may eventually need to use some JS anyway
