Refactoring as a Slow but Necessary Process

This post was originally published on August 28, 2020 on my blog.

I did it! I got my podcast episodes to render dynamically on the podcast page on my website.

Well, they're dynamically rendered via an object of pre-filled episode data in my JavaScript file instead of hard-coding a brand new Section element in my HTML file.

So, technically, I'm still hard-coding into the JS file, but... baby steps.

I had a total learning moment yesterday, though, when I discovered that you can't just insert a script into an 'insertAdjacentHTML' call in JS because by the time your script gets added, the page has already loaded - so, as I understood it, it's kind of like your script arrived at the station as the train had already left.

(Each script tag contained the the individual episode-player.)

To get around that, I had to create a script for each podcast-episode-section-HTML after the page was loaded and createElement('script') with and set the src of each as each individual epiosde's URL.

I also had to create a data-key attribute for each episode so that I could match up the episode to the corresponding element in the 'episodes' object that contains each episode's information.

That moment when everything came together, though - ugh! I live for that!!!

Here's the logic for rendering each episode (before adding the script tags to each episode):

function renderListItems(list) {
  let dataKey = 0;

  list.forEach(el => {

      let html = `<section class="episode" data-key=${dataKey}><h2 style="text-align: center;">${el.title}</h2> <div id="buzzsprout-player-${}" class="podcast-player"></div> <span>${el.description}Music credit to <a href="" rel="noopener" target="_blank">Le Gang</a></span></section>
      document.querySelector('#episode-list').insertAdjacentHTML('beforeend', html);


Enter fullscreen mode Exit fullscreen mode

So, once the page loads, all the HTML is rendered, and then the program runs back through and creates/adds the script tags containing the episode-player:

window.addEventListener('load', () => {

  // Render all podcast episodes

  // Add individual script tags for each podcast player
  const episodeHtml = document.querySelectorAll('.episode');
  episodeHtml.forEach(el => {

    let i = el.getAttribute('data-key');
    let script = document.createElement('script');

    script.src = episodes[i].url;


Enter fullscreen mode Exit fullscreen mode

Next step here is to get the episodes to populate by making a call to the Buzzsprout API (Buzzsprout is the podcast hosting service I use). This is great, because I've been wanting to build more things with APIs, so I can add that in there!

That'll be on today's plate, as well as more practice in my React ebook, which I'm steadily working my way through. I'm building a clone of a file list in GitHub at the moment, so I'm going to take what I've done fully apart in order to rebuild it using the knowledge I've already gained.

I mentioned in a previous post that I'm focusing on moving through the material very slowly as a means to move more quickly over the long run.

I know, it doesn't make sense right when we first read that; but honestly, it's a game-changer. I keep telling myself that if I move on quickly and without fully understanding a concept, it's going to cost me much more time down the line to have to go back and re-learn it.

So I'm taking that extra time as I'm learning something to make sure it's 100% dialed in.

Happy Friday.

P.S. Did you know I have a podcast with new episodes each Wednesday? Go listen right over here >>
