Welcome, tech enthusiasts! If you’re venturing into the world of TypeScript and Node.js, you’ve stumbled upon a gem. Ts.ED is the framework that elevates your Express applications by layering on enhanced features and guidelines.

What is Ts.ED?

Ts.ED is a Node.js and TypeScript framework built on top of Express. Imagine it as a decorator on a delicious cake, adding essential flavors and aesthetics to your web application code. With Ts.ED, you get a wealth of decorators and structure that help make your code more readable and less prone to errors.

Features of Ts.ED

• Create projects easily using the CLI.
• Support for various technologies like TypeORM, Mongoose, GraphQL, Swagger-ui, etc.
• Define classes as Controllers, Services, Middleware, and more.
• Versioning your REST APIs effortlessly.
• Testing capabilities built-in.

Building Your Server with Ts.ED

To understand how you can create a server using Ts.ED, consider it like preparing a dish: you need the right ingredients and a touch of finesse. Below is an example that outlines the steps to set up your server:

import Configuration, Inject from "@tsed/common";
import PlatformApplication from "@tsed/platform-express";
import cookieParser from "cookie-parser";
import compression from "compression";
import methodOverride from "method-override";

@Configuration({
  port: 3000,
  middlewares: [cookieParser, compression, methodOverride]
})
export class Server {}

Think of {@code Configuration} as your recipe card that tells you what to prepare. Setting up middleware like {@code cookieParser} and {@code compression} are the essential spices that add flavor to your dish (server), ensuring it runs smoothly.

Bootstrapping the Server

Here’s how you kickstart your server’s journey:

import $log from "@tsed/common";
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();

In this server bootstrapping process, you can think of the {@code bootstrap} function as the chef who coordinates the cooking process, ensuring everything comes together flawlessly.

Implementing a Controller

Controllers in Ts.ED are like the waitstaff in a restaurant, managing requests and responses. Here’s an example controller for a user resource:

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.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(200, User)
  async getUser(@PathParams("id") id: string): Promise {
    return this.usersService.findById(id);
  }

  @Post()
  @Status(201)
  @Summary("Create a new user")
  @Returns(200, User)
  async postUser(@Required() @BodyParams() user: User): Promise {
    return this.usersService.save(user);
  }
}

Here, the controller methods define how to handle different user-related requests, much like how a waiter takes your order, serves food, and handles any changes or cancellations gracefully.

Troubleshooting Tips

If you hit some bumps along the road while setting up or using Ts.ED, here are some quick troubleshooting ideas:

• Ensure all necessary packages are installed — missing dependencies can lead to runtime errors.
• Check your version compatibility; different versions of Node.js, TypeScript, or Express can conflict.
• Examine error logs for messages that provide insight into what might be wrong.
