Problem with Angular 2 Typings Paths in Typescript

Currently, I am in the process of learning how to create a Gulp build process with Angular 2 and Typescript. Following the Quick Start guide has allowed me to get everything up and running smoothly. However, I have decided to experiment with different folder structures, which has led to some issues. In particular, my app.component.ts file is struggling to find

import { Component } from 'node_modules/@angular/core';
. To solve this, I changed the path to
import { Component } from '../../../manager/node_modules/@angular/core';
, which works, but seems a bit cumbersome compared to other configurations.

My current directory looks like this:

build
  - css
  - js
  // all compiled files end up here
manager
  - node_modules
  - typings
  gulpfile.ts
  typings.json
  package.json
  tsconfig.json
source
  app.component.ts
  main.ts

In my app.component.ts file:

/// <reference path="../manager/typings/index.d.ts" />

import { Component } from '../manager/node_modules/@angular/core';
@Component({
  selector: 'my-app',
  template: '<h1>My First Angular 2 App</h1>'
})
export class AppComponent { }

I have a couple of questions:

  • Is there a way I can reference @angular/core without specifying the entire path?

  • Can I eliminate the need for <reference path="">?

The angular2-seed project manages to achieve this more elegantly, but I haven't been able to figure out their method yet. I suspect they might have a file handling the references for them.

Answer №1

Consider structuring your project folders in the following way:

build/
  css/
  js/
source/
  app.component.ts
  main.ts
node_modules/
typings/
gulpfile.ts
typings.json
package.json
tsconfig.json

Here's why: placing your tsconfig.json at the root level ensures that the TypeScript compiler can properly resolve modules like @angular/core. It's also a good practice to keep the node_modules folder and typings.json file at the root.

If you'd like to delve deeper into how TypeScript resolves modules, check out the Module Resolution documentation.
