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://tsed.dev/introduction/getting-started.html#installation
- 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

$3

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

``typescript
import {Configuration, Inject} from "@tsed/di";
import {PlatformApplication} from "@tsed/platform-http";
import "@tsed/platform-express";
import Path from "node:path";
import cookieParser from "cookie-parser";
import compress from "compression";
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.

`typescript
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:

`typescript
import {Inject} from "@tsed/di";
import {Summary} from "@tsed/swagger";
import {
Returns,
ReturnsArray,
Controller,
Get,
QueryParams,
PathParams,
Delete,
Post,
Required,
BodyParams,
Status,
Put
} 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()
protected usersService: UsersService;

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

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

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