brawler

brawler is a command-line tool and library to develop and deploy Cloudflare Workers with Deno and Wrangler.

It uses dnt (https://github.com/denoland/dnt) for Deno-to-Node transformation internally.

Warning
The project is still in an early-beta stage and not tested extensively yet.

Installation

Use the script installer of deno:

deno install -A --name brawler https://deno.land/x/brawler@0.1.0/cli.ts

Note that wrangler (https://github.com/cloudflare/wrangler2) must be also installed to use brawler.

Usage

Use brawler init, brawler dev, and brawler publish instead of wrangler init, wrangler dev, and wrangler publish, respectively.

You can pass any options available in wrangler.

See brawler --help and wrangler --help for details.

# create wrangler.toml and deno.json in the current directory
brawler init

# develop a script locally with hot-reload
touch index.ts
brawler dev index.ts

# publish it
brawler publish index.ts --name my-brawler-project

Examples

• /examples/hono: Hello-world with Hono framework
  • Hosted version: https://brawler-hono.hasundue.workers.dev

Background

Yes, we have denoflare (https://denoflare.dev), which is a great project letting you work with a pure Deno environment. The project bravely follows the philosophy of Deno.

However, denoflare still lacks a significant portion of functionality in wrangler, which is why this project exists for now.
