PageSpeed Tools

This is a collection of useful Pagespeed tools built by me or adapted from the internet.

Image Optimization

node imageOptimize.js # See @11ty/eleventy-img docs. 
# Basically takes images from input folder & creates a bunch of optimized copies in output folder at varying sizes
# Makes images in 2 file types, original file type (should be png or jpg ideally) & webp

Image.jsx

  • React component that renders bunch of template code for picture element to make use of the generated images
  • takes src = 'image name', sizes?='per html attribute', passes rest of props to img

Delay Third Party Code Execution

If you have lots of third party code slowing down the site. Simple fix is to delay it with a timeout for a few seconds so the rest of the website loads.

thirdPartyScriptDelay.ts

  • Function that takes in a list of urls & injects the script tags after 2s.

TODO

  • Create a react component for embeded youtube video
    • Takes an image src, youtube video url, play button style & color
    • Adds play button to image & on click shows pup-up with the youtube video
