• Fast, small, powerful, extensible core
• Generate real APIs with a single command
• Define your data and endpoints with OpenAPI

Installation

Make sure you have the following installed:

• Node.js >= 7.0.0
• TypeScript >= 2.0.0 npm i -g typescript
• TypeScript Node >= 3.0.0 npm i -g ts-node

Then in your Node.js project root, run:

Example

A basic controller:

export class UserController {
  async getUserByName(username: string): Promise<UserResponse> {
    const users = new UserRepository();
    const user = await users.findOne({where: {username: username}});
    if (!user) {
      throw createHttpError.NotFound(`User ${username} not found.`);
    }
    return new UserResponse(user);
  }
}
