How to create helper file full of functions in react native?

An alternative is to create a helper file where you have a const object with functions as properties of the object. This way you only export and import one object.

helpers.js

const helpers = {
    helper1: function(){

    },
    helper2: function(param1){

    },
    helper3: function(param1, param2){

    }
}

export default helpers;

Then, import like this:

import helpers from './helpers';

and use like this:

helpers.helper1();
helpers.helper2('value1');
helpers.helper3('value1', 'value2');

I am sure this can help. Create fileA anywhere in the directory and export all the functions.

export const func1=()=>{
    // do stuff
}
export const func2=()=>{
    // do stuff 
}
export const func3=()=>{
    // do stuff 
}
export const func4=()=>{
    // do stuff 
}
export const func5=()=>{
    // do stuff 
}

Here, in your React component class, you can simply write one import statement.

import React from 'react';
import {func1,func2,func3} from 'path_to_fileA';

class HtmlComponents extends React.Component {
    constructor(props){
        super(props);
        this.rippleClickFunction=this.rippleClickFunction.bind(this);
    }
    rippleClickFunction(){
        //do stuff. 
        // foo==bar
        func1(data);
        func2(data)
    }
   render() {
      return (
         <article>
             <h1>React Components</h1>
             <RippleButton onClick={this.rippleClickFunction}/>
         </article>
      );
   }
}

export default HtmlComponents;

Quick note: You are importing a class, you can't call properties on a class unless they are static properties. Read more about classes here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes

There's an easy way to do this, though. If you are making helper functions, you should instead make a file that exports functions like this:

export function HelloChandu() {

}

export function HelloTester() {

}

Then import them like so:

import { HelloChandu } from './helpers'

or...

import functions from './helpers' then functions.HelloChandu
