export in React Native - JavaScript
By: Faizal in React-Native Tutorials on 2023-04-07
In JavaScript, the export keyword is used to export a function, object, or value from a module so that it can be imported and used in other modules. In React Native, you can use the export keyword to export components, functions, or variables from a JavaScript file.
For example, let's say you have a Button component in a file called CustomButton.js. You can export it like this:
import React from 'react';
import { TouchableOpacity, Text } from 'react-native';
const CustomButton = (props) => {
const { onPress, title } = props;
return (
<TouchableOpacity onPress={onPress}>
<Text>{title}</Text>
</TouchableOpacity>
);
};
export default CustomButton;
Here, the CustomButton component is defined and then exported using the export default syntax. This means that when you import this module in another file, the CustomButton component will be the default export and can be used by importing it like this:
import CustomButton from './CustomButton';
You can also use named exports by exporting individual functions, objects, or values using the export keyword without the default keyword. For example:
export const myFunction = () => {
// ...
};
export const myValue = 'some value';
And you can import these named exports using their exact names in another file:
import { myFunction, myValue } from './myModule';
