A Cloudflare Worker that provides shorten link service.

This is a worker that provide shorten link service, you can submit a link to get a shorten key with/without expire seconds, then visit this short link by appending host before the key.

The appended host is the one that you registered to this worker.

Inside this worker, I made a built-in white list for some host that I don't want to set expire time as default.

To deploy this worker, you may want to modify some codes such as $whiteList, $expireTimeout and $defaultLen in src/index.ts. And then you can follow the steps to deploy to your Cloudflare account.

1. (Optional) Install wangler, and log in with your Cloudflare account.
2. Clone this repository.
3. cd cloudflare-shorturl-worker then npm install.
4. run wrangler kv:namespace create links to create a new KV namespace, then replace the id to [[kv_namespaces]] -> id in wrangler.toml, do NOT change the value of binding.
5. run wrangler whoami to get your account_id, then replace the account_id in wrangler.toml.
6. Change the $whiteList in src/index.ts to your domains.
7. Deploy workers by running wrangler deploy.
8. Done!

By sending OPTIONS request to any path, you will get the HTTP 204 No Content response.

By visiting https://example.com/AbxY in browser, if the key is correct, you will be redirected to the actual link.
