What is watchify?

Watchify is a browserify plugin that enables fast incremental bundling. It watches your files and updates the bundle whenever any of the source files change, making it ideal for development environments where quick feedback is essential.

What are watchify's main functionalities?

Incremental Bundling

This feature allows you to set up a watch on your files so that any changes trigger a rebundling process. The code sample demonstrates how to use watchify with browserify to watch for changes in 'main.js' and update 'bundle.js' accordingly.

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

const b = browserify({
  entries: ['main.js'],
  cache: {},
  packageCache: {},
  plugin: [watchify]
});

b.on('update', bundle);
bundle();

function bundle() {
  b.bundle().pipe(fs.createWriteStream('bundle.js'));
}

Custom Watch Options

Watchify allows you to customize the watch options, such as setting a delay before rebundling. The code sample shows how to set a custom delay of 1000 milliseconds before the rebundling process starts.

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

const customOpts = {
  entries: ['main.js'],
  cache: {},
  packageCache: {},
  plugin: [watchify],
  delay: 1000 // Custom delay before rebundling
};

const b = browserify(customOpts);

b.on('update', bundle);
bundle();

function bundle() {
  b.bundle().pipe(fs.createWriteStream('bundle.js'));
}
