decomposer

A lightweight TypeScript HTTP server that acts as a shim for image-builder-cli. Built with Bun and Hono, it provides a Unix socket-based API with automatic OpenAPI type generation from the image-builder-crc repo.

Prerequisites

• Bun >= 1.0.0
• Node.js >= 18 (for TypeScript compilation)

Installing Bun

npm install -g bun

Installation

1. Clone the repository:

git clone <repository-url>
cd decomposer

2. Install dependencies:

bun install

3. Generate OpenAPI types:

bun generate

Usage

Development

Start the development server with hot reload:

bun dev

Custom Configuration

You can specify a custom store path:

STORE_PATH=/custom/path/to/store bun start

Or pass it as a command-line argument:

bun start --store /custom/path/to/store

Or in a .env file:

STORE_PATH=/custom/path/to/store

Endpoints

See the list of supported endpoints and how to make requests from your terminal.

Socket Location

The server listens on a Unix socket at /run/decomposer-httpd.sock with permissions set to 775 for multi-user access.

Development Workflow

Code Generation

The project includes tools to automatically generate TypeScript types from OpenAPI specifications:

1. Filter OpenAPI spec:

   bun api:filter

   This downloads the latest OpenAPI spec from image-builder-crc and filters it to include only relevant endpoints.

2. Generate TypeScript types:

   bun api:generate

   This generates TypeScript interfaces and Zod schemas from the filtered OpenAPI spec.

3. Run both steps:

   bun generate

Document generation

Some of the endpoint documentation and example requests are generated. If you have added new endpoints, ensure you add some TSDocs with the endpoint description. If the module is new, you might have to add it to tools/docs/markdown.ts.

1. **Generate **:

   bun docs

Code Quality
