What it is

Ts.ED is a modern Node.js framework built with TypeScript. It offers a flexible structure with a fast learning curve, specifically designed to improve the developer experience. Ts.ED provides numerous decorators and guidelines to make your code more readable and less error-prone. It supports various platforms and tools, including Node.js/Bun.js, Express.js/Koa.js, CLI, and serverless architectures (e.g., AWS).

• Multi-platform: Easily build your server-side application using Express.js, Koa.js, CLI, or serverless platforms (e.g., AWS). It supports both Node.js and Bun.js runtimes. Learn more here.
• Configuration: Stop wasting time on configuration—your application comes preconfigured for a fast start! Try our CLI.
• Decorators: Use a wide range of decorators to structure your code, define routes, and implement methods with ease. Learn more here.
• Class-based: Define classes as Controllers, Models, Providers (DI), Pipes, and more, with JSON Schema and OpenAPI at the core of the framework.
• Testing: Testing is not optional—it's essential! Ts.ED includes built-in features to make testing your code simple and efficient. Learn more here.

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 Json Mapper (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,
• Inject Request, Response, Next object from Express request,
• Template (View),
• Testing.

Overview

Server example

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

import {Configuration, Inject} from "@tsed/di";
import {PlatformApplication} from "@tsed/platform-http";
import "@tsed/platform-express";
import cookieParser from "cookie-parser";
import compress from "compress";
import methodOverride from "method-override";

@Configuration({
  port: 3000,
  middlewares: ["cookie-parser", "compression", "method-override", "json-parser", "urlencoded-parser"]
})
export class Server {}

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

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

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/schema";
import {BadRequest} from "@tsed/exceptions";
import {UsersService} from "../services/UsersService.js";
import {User} from "../models/User.js";

@Controller("/users")
export class UsersCtrl {
  @Inject()
  private 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")
  @(Returns(200, Array).Of(User))
  async findUser(@QueryParams("name") name: string) {
    return this.usersService.find({name});
  }
}
