+# cloudflare-workers
+
+Monorepo for my personal [Cloudflare Workers](https://workers.cloudflare.com/).
+
+Uses [npm workspaces](https://docs.npmjs.com/cli/v7/using-npm/workspaces) (npm version 7+) to manage multiple `package.json` files (a separate package is required for each Cloudflare Worker). 
+
+# Quickstart
+
+1. Clone this repo
+```
+git clone https://github.com/ardislu/cloudflare-workers.git
+```
+
+2. Install dependencies
+```
+npm i
+```
+
+3. Authorize yourself with your Cloudflare account
+```
+npm run login
+```
+
+4. Set `account_id` in `wrangler.toml.example`:
+```
+account_id = [Account ID value from login]
+```
+
+5. For each Cloudflare Worker, make a copy of `wrangler.toml.example` and rename it to `wrangler.toml`. Put `wrangler.toml` in the folder for each worker. Set the Cloudflare Worker name in the copied `wrangler.toml`:
+```
+name = [Cloudflare Worker name]
+```
+
+6. Test that all Cloudflare Workers work:
+```
+npm run preview --workspaces
+```
+
+Or test an individual Worker:
+```
+npm run preview --workspace=[Cloudflare Worker name]
+```
+
+7. Publish all the Workers to Cloudflare
+```
+npm run publish --workspaces
+```
+
+Or publish an individual Worker:
+```
+npm run publish --workspace=[Cloudflare Worker name]
+```
+
+# Workers
+
+## proxy
+
+This is a minimal, basic reverse proxy.
+
+### Usage
+
+Proxy any request through the Cloudflare Worker by passing the **entire** URL as a query string to the Cloudflare Worker. So if your Cloudflare Worker domain is 
+```
+https://x.y.workers.dev
+```
+and the request you want to proxy is
+```
+https://api.example.com?param1=test1&param2=test2
+```
+then the final request URL should be
+```
+https://x.y.workers.dev?https://api.example.com?param1=test1&param2=test2
+```
+
+### Caching
+
+For simplicity, this code does not configure the `cf` headers on the `fetch` request that is sent to the Cloudflare proxy. Set the `cf` request headers to configure the Cloudflare Worker's behavior on caching. See: [Cache using fetch](https://developers.cloudflare.com/workers/examples/cache-using-fetch). 
+
+## instagram
+
+This reverse proxy embeds Instagram posts so they can be viewed without logging in.
+
+### Usage
+
+Same as `reverse-proxy`, but it will only work on instagram URLs in the format: `https://www.instagram.com/p/{POST_ID}/`.
