Core Features

• 📃 Generate payload representations from your AsyncAPI document (including Protobuf, RAML, OpenAPI Schema)
• 📊 Customize the generators output to your hearts desire
• 💫 Regenerate once the input changes
• 👀 Integrate it into any project (such as Next.JS, etc.)
• 💅 Create custom generators (read more)
• 🗄️ Protocol agnostic generator (docs)
• ⭐ And much more...

How it works

The Codegen Project is a generator that is built to live along side your projects to help you save time in the development phase, ensuring you spend as much time on the business logic as possible. It works by using your configuration file to know what it needs to generate.

Each input has different generates and all of them can be customized, or you can build your own generator right in the configuration file.

export default {
  inputType: 'asyncapi',
  inputPath: './asyncapi.json',
  language: 'typescript',
  generators: [
    {
      preset: 'payloads',
      outputPath: './src/payloads',
      serializationType: 'json', 
    },
    ...
  ]
};

In this example, the generator will read the AsyncAPI document located in same directory as the configuration file, and generate TypeScript models for all the payload including code to serialize the models to JSON.

Getting started

Its simple, install the CLI into your project or machine, setup the Codegen configuration file to include all the code your heart desire, customize it, and generate it at build time or whenever you feel like it.

Install

Installing the CLI can be done inside a project or within your system.

Package manager	MacOS x64	MacOS arm64	Windows x64	Windows x32	Linux (Debian)	Linux (Others)
NPM npm install --save-dev @the-codegen-project/cli npm install -g @the-codegen-project/cli Yarn yarn add @the-codegen-project/cli Pnpm pnpm add @the-codegen-project/cli Bun bun add @the-codegen-project/cli	Download curl -OL https://github.com/the-codegen-project/cli/releases/latest/download/codegen.x64.pkg Install sudo installer -pkg codegen.x64.pkg -target /	Download curl -OL https://github.com/the-codegen-project/cli/releases/latest/download/codegen.arm64.pkg Install sudo installer -pkg codegen.arm64.pkg -target /	Download and run codegen.x64.exe	Download and run codegen.x86.exe	Download curl -OL https://github.com/the-codegen-project/cli/releases/latest/download/codegen.deb Install sudo apt install ./codegen.deb	Download curl -OL https://github.com/the-codegen-project/cli/releases/latest/download/codegen.tar.gz Install tar -xzf codegen.tar.gz Symlink ln -s <absolute-path>/bin/codegen /usr/local/bin/codegen

You can find all the possible commands in the usage documentation.

Initialize

Add a configuration file, either manually or through the CLI;

codegen init

Customize it to your heart's desire!

Generate

With your configuration file in hand, time to generate the code and use it! This can be done manually or integrate into your build process. Checkout all the examples for inspiration how to do it.

👀 Goals

Besides the milestones, we have certain goals that we want to reach for various reasons;

• ⭐ Reach 50 stars - So we can publish the CLI on Brew and Chocolatey
• 📃 3 Published resources (blog post, video, etc)
