Bundling

webpack:
webpack is a powerful module bundler that analyzes your project’s dependencies and creates a bundled output file (or files) that can be optimized for the web. It supports code splitting, tree shaking, and various optimization techniques to reduce bundle size.
gulp:
gulp does not bundle files by default, but it can be set up to do so using plugins like gulp-browserify or gulp-webpack. Gulp's streaming architecture allows for efficient file processing during the bundling process, making it fast and memory-efficient.
browserify:
browserify bundles JavaScript files for the browser, allowing you to use Node.js-style require() calls in your client-side code. It creates a single bundled file that includes all dependencies, making it easy to include in your HTML.
grunt:
grunt itself does not bundle files, but it can be configured to run bundling tasks using plugins like grunt-contrib-uglify for minification or grunt-browserify for bundling. It provides a flexible framework for automating these tasks as part of your build process.

Task Automation

webpack:
webpack is primarily a module bundler, but it also supports task automation through its configuration file (webpack.config.js). You can define various tasks related to bundling, optimizing, and processing assets, making it a versatile tool for modern web development.
gulp:
gulp is a task runner that automates tasks using a code-centric approach. It allows developers to define tasks using JavaScript functions, providing a more intuitive and flexible way to automate workflows compared to configuration-based tools like Grunt.
browserify:
browserify focuses on bundling JavaScript files and does not provide built-in task automation features. However, it can be integrated with task runners like grunt or gulp to automate the bundling process as part of a larger build workflow.
grunt:
grunt is a task runner that automates repetitive tasks such as minification, compilation, unit testing, and linting. It uses a configuration file (Gruntfile) to define tasks and their execution order, making it highly customizable and extensible.

Configuration

webpack:
webpack requires a configuration file (webpack.config.js) where you define entry points, output settings, loaders, plugins, and other options. The configuration can be complex, but it offers a high level of customization and flexibility.
gulp:
gulp uses a code-based configuration approach, allowing developers to define tasks using JavaScript. This makes the configuration more dynamic and easier to read compared to Grunt’s JSON-like structure.
browserify:
browserify requires minimal configuration to get started. You can specify entry points, output files, and other options directly in the command line or through a simple configuration file.
grunt:
grunt requires a detailed configuration setup in a Gruntfile.js file, where you define tasks, plugins, and their settings. This can lead to verbose configurations, but it allows for highly customizable workflows.

Streaming

webpack:
webpack does not support streaming in the traditional sense, but it processes files in a way that allows for efficient handling of dependencies and assets. It creates a dependency graph and bundles files based on their relationships, which can lead to more optimized output.
gulp:
gulp supports streaming, allowing files to be processed and passed through tasks in real-time. This reduces the need for intermediate file writes and can significantly improve performance, especially for large files or complex workflows.
browserify:
browserify does not support streaming; it creates a single bundled file from the input files. This means that the entire bundling process must complete before the output file is generated.
grunt:
grunt does not support streaming; it processes files in a series of discrete steps. Each task reads input files, processes them, and writes output files before the next task begins. This can lead to increased disk I/O and slower performance for large projects.

Code Examples

webpack:

Simple Webpack Example

// webpack.config.js
const path = require('path');
module.exports = {
    entry: './src/index.js',
    output: {
        filename: 'bundle.js',
        path: path.resolve(__dirname, 'dist')
    },
    mode: 'development'
};

# Bundle with Webpack
npx webpack --config webpack.config.js

gulp:

Simple Gulp Example

// gulpfile.js
const gulp = require('gulp');
const uglify = require('gulp-uglify');
const rename = require('gulp-rename');

gulp.task('minify', () => {
    return gulp.src('src/*.js')
        .pipe(uglify())
        .pipe(rename({ suffix: '.min' }))
        .pipe(gulp.dest('dist'));
});

gulp.task('default', gulp.series('minify'));

# Run Gulp
gulp

browserify:

Simple Browserify Example

// main.js
const moduleA = require('./moduleA');
const moduleB = require('./moduleB');

console.log(moduleA);
console.log(moduleB);

// moduleA.js
module.exports = 'Hello from Module A';

// moduleB.js
module.exports = 'Hello from Module B';

# Bundle with Browserify
browserify main.js -o bundle.js

Simple Grunt Example

module.exports = function(grunt) {
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        uglify: {
            my_target: {
                files: {
                    'dist/output.min.js': ['src/input.js']
                }
            }
        }
    });
    grunt.loadNpmTasks('grunt-contrib-uglify');
    grunt.registerTask('default', ['uglify']);
};
