Waiter Framework

A lightweight, TypeScript-first web framework with built-in dependency injection and decorator-based routing.

Installation

npm install waiter-framework

Quick Start

import { bootstrapWaiter, Web, Get, WaiterRequest } from 'waiter-framework';

@Web('/api')
class UserController {
  @Get('/users')
  async getUsers(req: WaiterRequest) {
    return {
      statusCode: 200,
      body: { users: [] },
    };
  }
}

bootstrapWaiter(3000);

Features

• Decorator-based routing
• Built-in IoC container
• TypeScript support
• Interceptor/middleware system
• Zero configuration required

Dependency Injection

import { Web, Get, Inject, Wire } from 'waiter-framework';

@Wire('database')
class Database {
  query(sql: string) {
    // implementation
  }
}

@Web('/api')
class UserController {
  constructor(@Inject('database') private db: Database) {}

  @Get('/users')
  async getUsers() {
    const users = this.db.query('SELECT * FROM users');
    return { statusCode: 200, body: users };
  }
}

Interceptors

import {
  bootstrapWaiter,
  WaiterRequest,
  WaiterResponse,
} from 'waiter-framework';

const authInterceptor = async (
  req: WaiterRequest
): Promise<WaiterResponse | void> => {
  const token = req.serverRequest.headers['authorization'];

  if (!token) {
    return { statusCode: 401, body: { error: 'Unauthorized' } };
  }
};

bootstrapWaiter(3000, authInterceptor);

HTTP Methods

@Web('/api')
class ProductController {
  @Get('/products')
  async list() {
    /* ... */
  }

  @Post('/products')
  async create(req: WaiterRequest) {
    /* ... */
  }

  @Put('/products/:id')
  async update(req: WaiterRequest) {
    /* ... */
  }

  @Delete('/products/:id')
  async remove(req: WaiterRequest) {
    /* ... */
  }
}
