In this post we cover how to import and export a module on the same line in JavaScript

When using JavaScript modules exporting code is an essential, and often in larger projects or libraries, depending on how the project is structured, there will be dedicated files for importing and exporting to reduce the complexity when making use of the various functions and methods within it.

To import and export a module on the same line in JavaScript can be done in a couple of ways depending on what is needed and what is being imported/exported.

Here are the variations that can be used:

  • named export
  • wildcard/everything export
  • default exports
  • default to named export

Here is how to import and export a module on the same line in JavaScript:

1// Named export 
2export { CoffeeList } from './Coffee';
3
4// Wildcard/everything export
5export * from './Coffee';
6
7// Default exports
8export { default } from './Coffee';
9
10// Default to named export
11export { default as Coffee } from './Coffee';

JavaScript

JavaScript is a programming language that is primarily used to help build frontend applications.

It has many uses, such as making network requests, making dynamic or interactive pages, creating business logic and more.

JavaScript Module

A JavaScript module is a self-contained unit of code that encapsulates related functionality, variables, and data structures.

It provides a way to organize and modularize code, allowing for better code organization, reusability, and maintainability.

A module can contain functions, classes, variables, or any other code entities.

It provides a level of abstraction by exposing only the necessary functionality to other parts of the codebase while hiding the internal implementation details. JavaScript modules can be imported and exported, allowing them to be reused across different files and projects.

This modular approach enables developers to create more scalable and maintainable JavaScript applications.
