A Node.js and TypeScript Framework on top of Express

A Node.js and TypeScript Framework on top of Express. It provides a lot of decorators and guidelines to write your code.

What it is

Ts.ED is a framework on top of Express that helps you to write your application in TypeScript (or in ES6). It provides a lot of decorators to make your code more readable and less error-prone.

Features

Use our CLI to create a new project https://cli.tsed.io
Support TypeORM, Mongoose, GraphQL, Socket.io, Swagger-ui, Passport.js, etc…
Define class as Controller,
Define class as Service (IoC),
Define class as Middleware and MiddlewareError,
Define class as Converter (POJ to Model and Model to POJ),
Define root path for an entire controller and versioning your Rest API,
Define as sub-route path for a method,
Define routes on GET, POST, PUT, DELETE and HEAD verbs,
Define middlewares on routes,
Define required parameters,
Inject data from query string, path parameters, entire body, cookies, session or header,

Overview

Server example

Here an example to create a Server with Ts.ED:

import {Configuration, Inject} from "@tsed/di";
import {PlatformApplication} from "@tsed/common";
import "@tsed/platform-express";
import * as Path from "path";                              

export const rootDir = Path.resolve(__dirname);

@Configuration({
  rootDir,
  port: 3000
})
export class Server {
  @Inject()
  app: PlatformApplication;

  public $beforeRoutesInit() {
    const cookieParser = require('cookie-parser'),
      bodyParser = require('body-parser'),
      compress = require('compression'),
      methodOverride = require('method-override');

    this.app
      .use(cookieParser())
      .use(compress({}))
      .use(methodOverride())
      .use(bodyParser.json())
      .use(bodyParser.urlencoded({
        extended: true
      }));
  }   
}

To run your server, you have to use Platform API to bootstrap your application with the expected platform like Express.

import {$log} from "@tsed/common";
import {PlatformExpress} from "@tsed/platform-express";
import {Server} from "./Server";

async function bootstrap() {
  try {
    $log.debug("Start server...");
    const platform = await PlatformExpress.bootstrap(Server);

    await platform.listen();
    $log.debug("Server initialized");
  } catch (er) {
    $log.error(er);
  }
}

bootstrap();

To customize the server settings see Configure server with decorator

Controller example

This is a simple controller to expose user resource. It use decorators to build the endpoints:

import {Inject} from "@tsed/di";
import {Summary} from "@tsed/swagger";
import {Controller, Get, QueryParams, PathParams, Delete, Post, Required, BodyParams, Status, Put, Returns, ReturnsArray} from "@tsed/common";
import {BadRequest} from "@tsed/exceptions";
import {UsersService} from "../services/UsersService";
import {User} from "../models/User"; 

@Controller("/users")
export class UsersCtrl {
  @Inject()
  usersService: UsersService;

  @Get("/:id")
  @Summary("Get a user from his Id")
  @Returns(User)
  async getUser(@PathParams("id") id: string): Promise<User> {
     return this.usersService.findById(id);
  }

  @Post("/")
  @Status(201)
  @Summary("Create a new user")
  @Returns(User)
  async postUser(@Required() @BodyParams() user: User): Promise<User> {
    return this.usersService.save(user);
  }

  @Put("/:id")
  @Status(201)
  @Summary("Update the given user")
  @Returns(User)
  async putUser(@PathParams("id") id: string, @Required() @BodyParams() user: User): Promise<User> {
    if (user.id !== id) {
      throw new BadRequest("ID mismatch with the given payload")
    }

    return this.usersService.save(user);
  }

  @Delete("/:id")
  @Summary("Remove a user")
  @Status(204)
  async deleteUser(@PathParams("id") @Required() id: string ): Promise<User> {
     await this.usersService.delete(user);
  }

  @Get("/")
  @Summary("Get all users")
  @ReturnsArray(User)
  async findUser(@QueryParams("name") name: string){
    return this.usersService.find({name});
  }
}
