React Native: How to split a file up into multiple files and import them?

Question

I am writing my first app in react native and my js file is getting pretty big. What is the proper way to split the file up.

If i have something like

var MyClass = React.createClass({   ... }) 

Can I save it at myclass.js and include in by some command in another js file?

Answer 1

Here is the updated solution with using the import statement (in latest React-Native and generally Javascript adhering to ECMAScript6 and later):

file1 myClass.js:

export default class myClass {...} 

file2 app.js:

import myClass from './myClass'; 

This is the basic version using a single default export. You can also export named exports that have to be explicitly listed on import. For more info see export and import.

Answer 2

In general you can do the following:

var MyClass = React.createClass({     ... )}  module.exports = MyClass; 

This way you tell what should be publicly available.

And then, in your former big file you can load the contents like this:

var MyClass = require('./myclass.js'); 

Require returns the object that references the value of module.exports.
