Exploring namespaces in TypeScript compared to PHP coder's classmap and PSR-4

Transitioning from a PHP background, I am now immersing myself in TypeScript code.

In PHP, with the help of Composer's classmap and composer.json, I can declare namespaces PSR-4 style. By importing them properly using the `USE` statement, it gets resolved seamlessly.

While exploring this topic further on: How do I use namespaces with TypeScript external modules?

I found myself pondering over the question: - Is there any feature in Typescript that aids in resolving paths of classes instead of having to deal with relative paths? Currently, I find myself constantly using `../..` all the way to the root directory to retrieve the classes I have created within the app directory.

The issue of path resolution doesn't affect node_modules (for instance, I can be in the test folder and successfully call `import * as 'restify';` without any hiccups).

Answer №1

To create path aliases in your tsconfig.json file, you can utilize the following structure:

// ... other configurations hidden for brevity
  "baseUrl": "./src",
  "paths": {
    "components/*": ["components/*"]
  }

With this setup, importing items from src/components becomes easier:

import Whatever from 'components/Whatever';

For more information on module resolution and path mapping, refer to the documentation at this link.
