What is wrangler?
The wrangler npm package is a command-line tool for building, deploying, and managing Cloudflare Workers projects. It simplifies the process of working with Cloudflare's serverless platform, allowing developers to focus on writing code rather than managing infrastructure.
What are wrangler's main functionalities?
Creating a new Cloudflare Workers project
This command initializes a new Cloudflare Workers project in a directory named 'my-worker'. It sets up the necessary configuration files and project structure.
npx wrangler generate my-worker
Publishing a Cloudflare Worker
This command deploys your Cloudflare Worker to the Cloudflare network. It reads the configuration from the wrangler.toml file and uploads your code to Cloudflare.
npx wrangler publish
Previewing a Cloudflare Worker
This command allows you to preview your Cloudflare Worker in a browser before deploying it. It provides a temporary URL where you can test your worker.
