NOTICE:

This repository has been moved to https://github.com/inversify/inversify-express-utils in order to make an (official) Inversify npm package out of it. I'll keep this repository alive for now, but please check out the new one for any updates.

express-typescript-ioc

Example Express 4.x project in Typescript using Inversify as an IoC container.

To be used as a starting point for Typescript Express applications.

Usage

Run npm install && typings install followed by npm start will run the application.

Run npm test to run mocha tests.

Decorators

• @Controller(path, [middleware, ...])

Registers the decorated class as a controller with a root path, and optionally registers any global middleware for this controller.

• @Method(method, path, [middleware, ...])

Registers the decorated method as a request handler for a particular path and method, where the method is a valid method on the express.Router class.

• @SHORTCUT(path, [middleware, ...])

Shortcut decorators which are simply wrappers for @Method. Right now these include @Get, @Post, @Put, @Patch, @Head, @Delete, and @All. For anything more obscure, use @Method (Or make a PR 😄).

Example

FooController:

import * as express from 'express';
import { Controller, Get } from '../framework/decorators';
import { FooService } from '../services/foo-service';
import { injectable, inject } from 'inversify';

@Controller('/foo')
@injectable()
export class FooController {
    
    constructor( @inject('FooService') private fooService: FooService ) {}
    
    @Get('/')
    private index(req: express.Request): string {
        return this.fooService.get(req.query.id);
    }
}

FooService:

import { injectable } from 'inversify';

@injectable()
export class FooService {
    
    private data = {
      1: 'Foo',
      2: 'Bar'  
    };
    
    public get(id: number): string {
        return this.data[id];
    }
}

app.ts (composition root)

/// <reference path="../node_modules/inversify/type_definitions/inversify/inversify.d.ts" />
/// <reference path="../node_modules/reflect-metadata/reflect-metadata.d.ts" />

import "reflect-metadata";
import * as express from 'express';
import { Kernel } from 'inversify';
import { Server } from './framework/server';
import { FooController } from './controllers/foo-controller';
import { FooService } from './services/foo-service';

// set up kernel
var kernel = new Kernel();
kernel.bind<FooService>('FooService').to(FooService);
kernel.bind<FooController>('FooController').to(FooController);

// create server
var server = new Server(kernel);

server
    .build()
    .listen(3000, 'localhost', callback);

function callback() {
    console.log('listening on http://localhost:3000');
}
