Preface

This repository was forked in August 2022 to address critical security updates since the last official typescript-rest release for those still using the library.

Installation

This library only works with typescript. Ensure it is installed:

``bash
npm install typescript -g
`

To install typescript-rest:

`bash
npm install typescript-rest --save
`

Configuration

Typescript-rest requires the following TypeScript compilation options in your tsconfig.json file:

`typescript
{
"compilerOptions": {
"experimentalDecorators": true,
"emitDecoratorMetadata": true,
"target": "es6" // or anything newer like esnext
}
}
`

Basic Usage

`typescript
import * as express from "express";
import {Server, Path, GET, PathParam} from "typescript-rest";

@Path("/hello")
class HelloService {
@Path(":name")
@GET
sayHello( @PathParam('name') name: string ): string {
return "Hello " + name;
}
}

let app: express.Application = express();
Server.buildServices(app);

app.listen(3000, function() {
console.log('Rest Server listening on port 3000!');
});

`

That's it. You can just call now:

`
GET http://localhost:3000/hello/joe
`

Using with an IoC Container

Install the IoC container and the serviceFactory for the IoC Container

`bash
npm install typescript-rest --save
npm install typescript-ioc --save
npm install typescript-rest-ioc --save
`

Then add a rest.config file in the root of your project:

`json
{
"serviceFactory": "typescript-rest-ioc"
}
`

And you can use Injections, Request scopes and all the features of the IoC Container. It is possible to use it with any other IoC Container, like Inversify.

Example:

`typescript
class HelloService {
sayHello(name: string) {
return "Hello " + name;
}
}

@Path("/hello")
class HelloRestService {
@Inject
private helloService: HelloService;

@Path(":name")
@GET
sayHello( @PathParam('name') name: string): string {
return this.sayHello(name);
}
}
``
