What is browserify?

Browserify is a tool for Node.js that enables developers to use the require() function from Node in the browser. It bundles up all of your JavaScript files and dependencies into a single file that can be served to the browser. It allows for modular code in the client-side environment by leveraging the CommonJS module pattern.

What are browserify's main functionalities?

Bundle modules for the browser

This feature allows you to bundle all your JavaScript files and dependencies into a single file. The code sample demonstrates how to create a bundle starting with 'main.js' and output it to 'bundle.js'.

const browserify = require('browserify');
const fs = require('fs');

let b = browserify();
b.add('main.js');
b.bundle().pipe(fs.createWriteStream('bundle.js'));

Transformations

Browserify can apply transformations to the files as they are added to the bundle. This is useful for tasks like compiling ES6 syntax to ES5 using Babel, as shown in the code sample.

const browserify = require('browserify');
const babelify = require('babelify');

browserify('./src/app.js')
  .transform(babelify, { presets: ['@babel/preset-env'] })
  .bundle()
  .pipe(process.stdout);

Plugins

Browserify can be extended with plugins that can add additional functionality. In the code sample, the watchify plugin is used to automatically re-bundle the file whenever changes are detected.

const browserify = require('browserify');
const watchify = require('watchify');

const b = browserify('./src/app.js', { plugin: [watchify] });
b.on('update', bundle);
function bundle() {
  b.bundle().pipe(fs.createWriteStream('bundle.js'));
}
