TypeScript Modules:
Types and Use Cases
Ever wondered how TypeScript keeps our projects organized and scalable? Let's dive into the world of modules—your best pals for structuring code like a pro! ??
What are Modules?
Think of modules as neatly packed compartments in a toolbox. They help us keep our code clean by allowing us to organize functions, variables, or even classes into separate files. TypeScript supports both ES modules (import/export) and CommonJS (require/module.exports), catering to different project needs.
Types in Modules
TypeScript brings an extra layer of reliability with type annotations in modules. By specifying types, we ensure that our variables and functions play nice with each other, catching errors before they sneak into production code. It’s like having a vigilant assistant who double-checks everything!
Use Cases
领英推荐
// utilities.ts
export function double(num: number): number {
return num * 2;
}
// main.ts
import { double } from './utilities';
console.log(double(5)); // Output: 10
2. Dependency Management: They make managing dependencies a breeze. Whether it's integrating a third-party library or keeping your project components neatly separated, modules have got your back.
// calculator.ts
export function add(a: number, b: number): number {
return a + b;
}
// main.ts
import { add } from './calculator';
console.log(add(3, 7)); // Output: 10
3. Scaling Projects: As projects grow, modules prevent code from turning into an unreadable jungle. Each file becomes a self-contained story, contributing to the larger narrative of your application.
