2. Download and install NodeJS and Rust v1.75.0+, or use the provided .devcontainer setup for an environment.
3. Run npm install to install all dependencies needed to build/deploy.
4. Setup a KV namespace on Cloudflare by following their documentation.
5. Create a 'wrangler.toml' file with the following contents at the root of the repository:

   name = "workerlink"
   main = "build/worker/shim.mjs"
   compatibility_date = "2024-04-01"
   kv_namespaces = [
       { binding = "links", id = "<KV ID>" } # Replace <KV ID> with the ID of the KV namespace you setup earlier.
   ]
   
   [vars]
   AUTH_TOKEN = "" # Set this to the token you want to use for authentication.
   
   [build]
   command = "cargo install -q worker-build && worker-build --release"

6. Run npm run deploy to deploy the worker to Cloudflare; You will be prompted to authenticate with Cloudflare during this process so the worker can be deployed using your account.

Examples

• In a browser: Use a redirect.
  Navigate to https://<WORKER_URL>/<ID> and the browser will automatically direct.

• In a browser: See where an ID redirects to.
  Navigate to https://<WORKER_URL>/<ID>/where and the redirect url will be shown in plaintext.

• Using curl: Create/Update a new redirect.

  curl --request POST \
    --url 'https://<WORKER_URL>/<ID>' \
    --header 'Authorization: <AUTH_TOKEN>' \
    --header 'content-type: application/json' \
    --data '{
    "url": "<URL_TO_REDIRECT_TO>",
    "expiry_timestamp": unix_timestamp | null,
    "max_views": number | null,
    "overwrite": boolean,
    "disabled": boolean
  }'

• Using curl: Delete an existing redirect.

  curl --request DELETE \
    --url 'https://<WORKER_URL>/<ID>' \
    --header 'Authorization: <AUTH_TOKEN>'

• Using curl: Check the underlying JSON of a redirect.

  curl 'https://<WORKER_URL>/<ID>/details' \
      --header 'Authorization: <AUTH_TOKEN>'
