Overview

A Cloudflare Workers script to use as a simple redirect system.

The data.json file can be used as dummy input or git enabled backup for your production environment.

The motivation for doing such a thing is GUI or IAM enabled acces to these variables from other CloudFlare tools, essentially promoting observability.

Deploy as Cloudflare Worker

I use this service for my profile at github.com. Currently, the service is hosted on a free tier of Cloudflare Workers and limited at 100K requests per day. Make sure to make the appropriate changes in wrangler.toml first.

Usage

Configure KV

To successfully run the redirect worker we need to set up some KV namespaces.

Generate new namespace_ids for the KV keys it wrangler.toml and follow the instructions:

# dev environment
wrangler kv:namespace create "REDIRECTS"
wrangler kv:namespace create "REDIRECTS" --preview
# production environment
wrangler kv:namespace create "REDIRECTS" --env production
wrangler kv:namespace create "REDIRECTS" --env production --preview

After you are done editing check if the changes are correct:

wrangler kv:namespace list

Test data

Upload some data to the REDIRECTS namespace:

# dev environment
wrangler kv:bulk put --binding="REDIRECTS" ./src/data.json
wrangler kv:bulk put --binding="REDIRECTS" ./src/data.json --preview
# production environment
wrangler kv:bulk put --binding="REDIRECTS" ./src/data.json --env production
wrangler kv:bulk put --binding="REDIRECTS" ./src/data.json --env production --preview
