<h1>Rewriting the tech stack</h1>
|
||||
<h5 class="post-date">Fri, 18 Sep 2020</h5>
|
||||
|
||||
<p>
|
||||
Once upon a time, I needed to draw some Bezier curves because I was trying to create a Japanese kanji composition system that turned strokes
|
||||
into outlines, and that required knowing how to offset Bezier curves and... at the time (2011, time flies) there was no good single source of
|
||||
information for Bezier curves on the web. So I made one. Sure it started small, but it turns out that if you just keep adding bits to
|
||||
something, several years later you have quite the monster, and a single HTML file becomes intractible.
|
||||
</p>
|
||||
<p>
|
||||
So, in 2016, when <a href="https://reactjs.org/">React.js</a> exploded onto the scene, I rewrote the primer as a React app, and it became a
|
||||
lot easier to maintain. Like, <em>a lot</em> a lot. However, there was a downside: no JS meant no content. Sure, server-side rendering sort of
|
||||
existed, but not really, and because the Primer is hosted through github, there was no "server" to run. Plus, trying to rehydrate an app the
|
||||
size of the Primer from a giant HTML file had truly <em>dire</em> performance.
|
||||
</p>
|
||||
<p>
|
||||
So I left it a regular React app, and every time I thought "wouldn't it be nice if it was just... a web page again?" the browser landscape
|
||||
just hadn't caught up. Finally, in 2020, things are different: with a global pandemic, and some vacation time, and something random causing me
|
||||
to look up the state of HTML custom elements, everything was pointing at it being time to finally, <em>finally</em>, turn the Primer back into
|
||||
a normal web page.
|
||||
</p>
|
||||
<p>
|
||||
The new tech stack is, frankly, pretty amazing. It does some things that weren't possible even half a year before I started the rewrite, let
|
||||
alone being possible in 2016, and so because so much has changed, this post will be the first in a series of posts on how the new tech stack
|
||||
works.
|
||||
</p>
|
||||
<p>To give a bit of a teaser, some of the things I'll be writing about:</p>
|
||||
<ul>
|
||||
<li>Essentially reinventing (a limited form of) Processing.js</li>
|
||||
<li>Writing a custom build system, because I'm exhausted with Webpack and hope to never use it again.</li>
|
||||
<li>Using modern ES module code that runs in both the browser and Node.js.</li>

||||

|
||||
<li>A custom <code><graphics-element></code> element that turns a <code>src="blah.js"</code> into an interactive canvas graphic...</li>
|
||||
<li>
|
||||
...with that same source code being read in and run by Node.js <em>on a canvas</em> to generate fallback images so that even without JS,
|
||||
graphics work.

<li>Responsive CSS, so the content intelligently reflows where possible.</li>
|

<li>A "Live build" setup for working on the content and code.</li>
|

<li>Automatic link-checking to make sure none of the links in the Primer lead you to a 404.</li>
|

<li>This "news" section, so that I can write posts to go along with new sections getting added, or notable changes being made.</li>
