What I learned - Image Resize on Cache Miss

The task:

I really wanted a way to create resized images on the fly just by specifying the size of the image in the request URL. So, if I had the image kitty.jpg but wanted to resize it to be 100px by 100px, would simply request kitty-100x100.jpg, the server would realize it doesn't exists and create it, and the resized image would be returned to me.

The solution:

I was following this guide written by John Pignata. It is an interesting solution and fit my needs but I did run into some caveats. Below are some of the gotchas I encountered.

1) There are two S3 domains you can point your CloudFront distribution at:

Query

• document.querySelector(): returns first matching element
• document.querySelectorAll(): returns all matching elements
• document.getElementById(id)

DOM Node

• addEventListener(event, cb)
• appendChild(node)
• childNodes
• classList

Spoiler warning

Spoiler text. Note that it's important to have a space after the summary tag. You should be able to write any markdown you want inside the <details> tag... just make sure you close <details> afterward.

console.log("I'm a code block!");

  @observable firstName = "";
