Notes for building and using CloudFlare Workers

Converting an old CloudFlare Service Worker to Worker ES Module

CloudFlare's baseline guidance can be found at (https://developers.cloudflare.com/workers/learning/migrate-to-module-workers/)

If you are using variables, simply prepend env. to the beginning of each request, since global bindings are no longer permitted.

Example:
await accesslogs.list({ prefix: "someevent" })
Becomes
await env.accesskeys.list({ prefix: "someevent" })

Make use of environment variables (found under Settings) to store configuration variables

Under Settings -> Variables, add configuration details that can be utilized within your Workers.

Additionally, you can choose to encrypt sensitive values; use them just like a normal value within your code.

Example:
Create an encrypted variable called, "secret" and assign an API key and use it directly within your code
const secretKeyEnc = new TextEncoder().encode(env.secret)
