• Modular architecture

Installation

bun add bunad

Usage

1. Define a Controller

import { Controller, Get, Post, Body, Param } from "bunad";

@Controller("/users")
class UserController {
  @Get("/")
  getAllUsers() {
    return [
      /* ...users */
    ];
  }

  @Get("/:id")
  getUser(@Param("id") id: string) {
    return { id };
  }

  @Post("/")
  createUser(@Body() user: any) {
    return { id: "new", ...user };
  }
}

2. Register Controllers and Start Server

import { createApp, Module } from "bunad";

@Module({
  controllers: [UserController],
})
class AppModule {}

createApp(AppModule).listen(3000);
