☁️ Link Shortener on Cloudflare Workers

This is a link shortener that runs as a Cloudflare Worker. It's the finished code for the Build a Link Shortener with Cloudflare Workers tutorial on DEV.to. To deploy it on your own Cloudflare account, follow these steps:

1. Clone this repo: git clone https://github.com/mm/cf-shortener.git

2. Ensure Wrangler v2+ is installed on your local machine:

   $ wrangler version
   

   If you see wrangler v1...., then you need to remove the old version:

   $ npm uninstall -g @cloudflare/wrangler
   

   Now install if needed; note the missing "@cloudflare/":

   $ npm install -g wrangler
   $ wrangler version
   ⛅️ wrangler 2.*.* 
   

3. Authenticate with Cloudflare:

   $ wrangler login
   

4. In the project directory, copy the wrangler.example.toml file to wrangler.toml. Get your Cloudflare Account ID by running wrangler whoami. In wrangler.toml, replace ACCOUNT_ID_HERE with the account ID you get from Wrangler or the Workers dashboard.

5. Create the Workers KV namespace for the shortener:

   $ wrangler kv:namespace create "SHORTEN"
   $ wrangler kv:namespace create "SHORTEN" --preview
   

   Copy the id you get in the terminal output to wrangler.toml in place of ID_HERE, and copy the preview_id you get in the terminal output in place of PREVIEW_ID_HERE.

6. Deploy the Worker: wrangler publish
