Cloudflare Workers Internship Application: Full-Stack
This is my submission for the Cloudflare 2020 Summer Internship.
What is it?
This application is hosted on Cloudflare Workers and randomly sends user one of two pages, A/B testing style.
How does it work?
- Uses
fetch()to get the page variants fromhttps://cfw-takehome.developers.workers.dev/api/variants - Randomly selects which link variant to use and uses
fetch()again to get the HTML page source - Serves the HTML page in the response
Extra features
- Checks for cookie to determine if user has visited before in order to serve the same page, if not serves random page and sends back cookie for future use
- Uses HTMLRewriter to modify HTML page source before sending
- Hosted on custom domain alecbarnard.io through Cloudflare
Try it
Try it out for yourself at internship.alecbarnard.workers.dev or alecbarnard.io.
Use Chrome DevTools to inspect and clear cookies to see if you get a different page version.
