`wrangler deploy` usage in git-mcp codebase.

In this article, we will review wrangler deploy usage in git-mcp codebase. We will look at:

1. Deploy script in git-mcp package.json

2. What is Wrangler?

3. wrangler.jsonc in git-mcp

Deploy script in git-mcp package.json

In git-mcp/package.json, at line 9, you will find the following script:

"scripts": {
    "build": "react-router build",
    "deploy": "npm run build && wrangler deploy",

This deploy script is used to prepare a build and this runs the wrangler deploy command.

What is Wrangler?

Wrangler, the Cloudflare Developer Platform command-line interface (CLI), allows you to manage Worker projects.

• API : A set of programmatic APIs that can be integrated with local Cloudflare Workers-related workflows.

• Bundling : Review Wrangler’s default bundling.

• Commands : Create, develop, and deploy your Cloudflare Workers with Wrangler commands.

• Configuration : Use a configuration file to customize the development and deployment setup for your Worker project and other Developer Platform products.

• Custom builds : Customize how your code is compiled, before being processed by Wrangler.

• Deprecations : The differences between Wrangler versions, specifically deprecations and breaking changes.

• Environments : Use environments to create different configurations for the same Worker application.

• Install/Update Wrangler : Get started by installing Wrangler, and update to newer versions by following this guide.

• Migrations : Review migration guides for specific versions of Wrangler.

• System environment variables : Local environment variables that can change Wrangler’s behavior.

wrangler.jsonc in git-mcp

In git-mcp/wrangler.jsonc, you will find the following code:
