Multiple React components in a single module

Question

I am new to the whole browserify thing. I have been trying to use browserify + reactify + gulp to transform, minify and combine a React application. As long as I have a single React.createClass with a single module.exports = MyComponent everything works fine. Since I have several shared components I physically host in the same file and reuse across projects, I would like to export more than one component. I have tried an array:

module.exports = [Component1, Component2]

and have also tried an object with multiple properties:

module.exports = {Comp1: Componenet1, Comp2: Component2} and have also tried in-lining the calls to createClass in the object, but that didn't help.

Is there a way to do this or do I have to split every component in to a seperate JSX file?

Answer 1

You can do like this, with an index.js file into your /components/ folder

/components/index.js

import Users from './Users/Users';
import User from './Users/User';


module.exports = {
  User,
  Users
}

IMPORT

import { Users, User } from './components';

As you can see, I named my file index.js, it prevent me from write it in the import declaration. If you want to name your file with another name than index.js, you'd have to write the name of the file in the import, Node won't guess it ! ^^

Answer 2

I have put multiple components in one file and export the object like you suggested.

module.exports = {
    comp1: Component1,
    comp2: Component2
}

Then where they are used do

var comp1 = require('your/path/to/components').comp1;
var comp2 = require('your/path/to/components').comp2;

Answer 3

Define functions

function sum(a, b) {
  return a + b
}
function sub(a, b) {
  return a - b
}
function mul(a, b) {
  return a * b
}

Define export export { sum, sub, mul }

Import functions you need import { sum, sub } from 'myfile' or all the functions import * as myfunctions from 'myfile'

and call as sum(1+1) or myfunctions.sum(1+1)

Answer 4

I'm new to react and I faced this situation too. And this is how I overcame it.

Along to this question it also answers the following error:

export 'default' (imported as 'db') was not found in './index.js' (possible exports: auth, db).

1st method - use export default & don’t destructure while importing

index.js

const db = // module 1;
const auth = // module 2;

export default { db, auth}; // notice the default keyword here

while importing in other file

import db from "./index.js"

2nd method - use export & destructure while importing

index.js

const db = // module 1;
const auth = // module 2;

export { db, auth};

and while importing

import { db } from "./index.js"

Please note when to use destructuring while using the import statement
