Wrangler CLI setup

To install wrangler, ensure you have npm installed, then run:

npm install -g @cloudflare/wrangler

wrangler --version

Router

index.js is the content of the Workers script.

Debugging

wrangler preview --watch

This command will build your project, upload it to a unique URL, and open a tab in your browser to view it. This allows you to quickly test your project running on the actual Workers runtime, and optionally, even share it with others too.

Publishing changes

We need to edit wrangler.toml file and add our Cloudflare account_id - more information about publishing your code can be found in the documentation.

Once you are ready, you can publish your code by running the following command:

wrangler publish
