Can I export more than one object using module.exports? (2024)

FAQs

Can I export more than one object using module.exports? ›

The quick answer is, Yes. require only pulls in items identified in module. exports .

Every module can have two different types of export, named export and default export. You can have multiple named exports per module but only one default export. Each type corresponds to one of the above syntax.

To export multiple components from one file, you can use named exports. This allows you to keep related components together in a single file and import them selectively in other parts of your application.

By module. exports, we can export functions, objects, and their references from one file and can use them in other files by importing them by require() method.

Exporting an Object

The most common method to export multiple values is to package them into an object. This allows you to group related values together and export them as a single entity.

In a nutshell, a module is a file with Python code. Instead of having a single Python file that includes all your code, you can use multiple files. This allows you to organize your code in multiple files, making it easier to reuse and manage your code.

The export keyword allows these elements to be used in other JavaScript files, thus making the code reusable and modular. There are two main types of export in React: named export and default export.

Once you install the package from the package manager, you can just select any mesh game objects (multiple at a time) and right-click to export to FBX and the window for it will pop-up to set a few options and name the FBX file.

A file can have no more than one default export, but it can have as many named exports as you like.

What is the difference between export and module export? ›

If you are exporting a single object, function, or value, you can use either module. exports or exports . If you are extending exports with additional properties or methods, use exports . If you need to replace the entire exports object, use module.

Named export

Suppose we want to export these two functions in another React component (file or module). To export these functions into another component as a named export, we just need to use the export keywords in front of the functions.

JavaScript does not return multiple values just by calling the function therefore it can be achieved using arrays or objects. To return multiple values from a function using arrays, create an array of the variables that are to be returned and then call the array.

exports function inside the module. js file to export the function to the main index. js file. Now the question is, "Can we export multiple functions at a time?" The answer is Yes.

Yes, you can import a module more than once in Python. However, when you import a module multiple times in the same program, Python only executes the module's code the first time it is imported. Subsequent imports simply reference the already-loaded module, and no additional code is executed.

Instead of module. exports we could also use the alias exports though this has an important caveat which we will cover in the next section. An example of how we can export both a subtract and add function using the exports keyword can be seen below. // main.

Import multiple items at once

You can import multiple items from the same module at once by listing them, separated by commas. If the line gets too long, you can use parentheses () to split it across multiple lines. Here, e represents Euler's number, and exp() is the exponential function.

The rules are quite simple: the same module is evaluated only once, in other words, the module-level scope is executed just once. If the module, once evaluated, is imported again, it's second evaluation is skipped and the resolved already exports are used.
