Importing dynamically into Ionic 2 from locations other than the "node_modules" directory

I've recently reviewed the documentation for ModuleResolution in TypeScript on this page: https://www.typescriptlang.org/docs/handbook/module-resolution.html#node

My understanding is that all files I wish to import must reside within the node_modules directory. Is there a way to import files located elsewhere?

For instance, if I have the following folder structure (src/MyApp/):

├── Console
│   └── Console.ts 
├── Interfaces
│   └── CredentialsInterface.ts 
└── Service
    ├── Authentication.ts
    ├── Router.ts
    └── Connector.ts

Then let's say in my src/pages/login/login.ts, I currently use this to import Console.ts:

import { Console } from '../../MyApp/Console/Console'; 

However, I aim to achieve something like this:

import { Console } from '@MyApp/Console/Console';

With @MyApp serving as an alias for src/MyApp.

Given potential file or folder movements in the future, I would prefer not to manually update each file with hardcoded paths. This functionality is available in other tools like Composer. Is there a similar capability in TypeScript? Thank you in advance!

Answer №1

In order to achieve this, you will need to make adjustments to a few files. Start by updating the tsconfig.json file and extending the webpack configuration.

In the tsconfig.json file, add the following under compilerOptions:

"baseUrl": "./src",
"paths": {
  "app/*": [
    "app/*"
  ],
  "@env": [
    "environments/environment"
  ],
  "interfaces/*": [
    "interfaces/*"
  ],
  "providers/*": [
    "providers/*"
  ],
  "validators/*": [
    "validators/*"
  ]
}

I have provided a link to a brief documentation that I created, which demonstrates how to implement these changes and utilize the environments of angular-cli.
