What are the differences between TypeScript module aliases and relative paths?

TypeScript module aliases allow you to create custom paths for your imports, making them cleaner and easier to manage. Relative paths, on the other hand, are based on the file structure and can become cumbersome as your project grows.

Can you give me an example of how to set up module aliases?

Sure! You can set up module aliases in your tsconfig.json file by adding a paths property under compilerOptions. For example:

"compilerOptions": {
  "baseUrl": "./src",
  "paths": {
    "@components/*": ["components/*"],
    "@utils/*": ["utils/*"]
  }
}

This allows you to import components like this: import Button from '@components/Button';.

What are the advantages of using module aliases?

Using module aliases can improve code readability and maintainability. It reduces the complexity of import statements, especially in large projects, and makes it easier to refactor code without breaking imports.

Are there any downsides to using module aliases?

One downside is that it can add a layer of complexity for new developers who may not be familiar with the aliasing setup. Additionally, if not documented well, it can lead to confusion about where to find certain modules.
