Browserify - How to call function bundled in a file generated through browserify in browser

Question

I am new to nodejs and browserify. I started with this link .

I have file main.js which contains this code

var unique = require(\'uniq\');

var data          


        

Answer 1

Minimal runnable example

This is basically the same as: https://stackoverflow.com/a/43215928/895245 but with concrete files that will allow you to just run and easily reproduce it yourself.

This code is also available at: https://github.com/cirosantilli/browserify-hello-world

index.js

const uniq = require('uniq');

function myfunc() {
  return uniq([1, 2, 2, 3]).join(' ');
}
exports.myfunc = myfunc;

index.html

Node.js usage:

#!/usr/bin/env node

const browserify_hello_world = require('./index.js');

console.log(browserify_hello_world.myfunc());

Generate out.js for browser usage:

npx browserify --outfile out.js --standalone browserify_hello_world index.js

Both the browser and the command line show the expected output:

1 2 3

Tested with Browserify 16.5.0, Node.js v10.15.1, Chromium 78, Ubuntu 19.10.
