TypeScript for Coders – Chapter 15 : Modules – exporting and importing

Free eBooks for Beginners

TypeScript is a programming language that is a superset of JavaScript, meaning that it has all the features of JavaScript and more. It is becoming increasingly popular among coders for its ability to help catch errors before the code is run, making the development process easier and less time-consuming.

One of the features in TypeScript is the ability to use modules, which allow you to organize your code into smaller, reusable chunks. This helps you keep your code organized and makes it easier to maintain over time.

When working with modules in TypeScript, you will often need to export and import code from one module to another. Exporting code allows you to make it available to other parts of your application, while importing code allows you to use code from other modules in your own code.

Exporting code in TypeScript is simple, you just need to add the “export” keyword before the code that you want to make available. For example, if you have a function that you want to make available to other parts of your application, you would write:

export function myFunction() { // code here }

To import the exported code in another module, you use the “import” keyword, followed by the name of the module that you want to import. For example:

import { myFunction } from './myModule';

This will make the myFunction function available to your code, allowing you to use it just like any other function.

In addition to exporting and importing individual functions, you can also export and import entire classes or interfaces. For example, if you have a class that you want to make available to other parts of your application, you would write:

export class MyClass { // code here }

To import the class, you would write:

import { MyClass } from './myModule';

Exporting and importing code using modules in TypeScript makes it easier to keep your code organized and maintainable. It also makes it easier to reuse code in different parts of your application, saving you time and effort in the long run.
