How statistics are calculated
We count how many offers each candidate received and for what salary. For example, if a Flutter with Webpack with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.
The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.
Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Where is Webpack used?
Bundle Up Time!
- Oh, the joy of wrangling a spaghetti mess of scripts! Webpack jumps into this food fight, turning a tangled bowl of script pasta into a neat, microwave-ready dish. No more script tag sobbing.
Lazy Loading Lounge
- In the realm of "I'll do it later," Webpack's lazy loading is the procrastinator's best pal. It sits back on a code couch, delivering chunks of code only when the app's ready for a snack, keeping things snappy and users happy.
Cache Crusader
- Users crave speed like a caffeine fix in the morning. Webpack serves up versioned files with a side of cache-busting, keeping browser stashes fresh and loading times zippy.
The Mix 'n' Match Maestro
- Treating your modules like a cosmic DJ, Webpack mixes different tech tunes together. JavaScript, CSS, or images, it splices 'em all so your website hits those high notes with ease.
Webpack Alternatives
Parcel
Parcel is a web application bundler, offering blazing fast performance utilizing multicore processing, with no configuration required.
// Installation via NPM
npm install parcel-bundler --save-dev
// Package.json script
"scripts": {
"start": "parcel index.html"
}
- Simplicity of setup with zero configuration.
- Out-of-the-box support for various file types.
- Performs very fast builds by utilizing multicore processing.
- Limited plugin ecosystem compared to Webpack.
- Less configurable for complex projects.
- Community support and resources are not as extensive.
Rollup
Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application.
// Rollup config example
import json from '@rollup/plugin-json';
export default {
input: 'src/main.js',
output: [
{ file: 'bundle.js', format: 'umd' }
],
plugins: [ json() ]
};
- Optimized for bundling libraries with tree-shaking.
- Produces smaller bundles for better performance.
- Supports ES6 modules natively.
- Not as versatile for complex apps as Webpack.
- Plugin ecosystem is smaller.
- Configuration can become cumbersome for larger projects.
Browserify
Browserify lets you require('modules') in the browser by bundling up all of your dependencies.
// Example command line usage
browserify main.js -o bundle.js
// Using the API
const browserify = require('browserify');
browserify('./main.js')
.bundle()
.pipe(fs.createWriteStream('bundle.js'));
- Simple to use with a focus on traditional Node.js module system.
- Plug-in infrastructure allows for extending capabilities.
- Transforms help in using Node.js modules in the browser.
- Not as fast as other bundlers like Parcel or Webpack.
- Lacks modern features like code splitting natively.
- Can produce larger bundles than its competitors.
Quick Facts about Webpack
The Dawn of Bundling: Webpack's Conception
Ever wondered what a blacksmith, a bundle of sticks, and your web app have in common? Well, it's the art of bringing things together, which is exactly what Tobias Koppers did in 2012 when he unleashed Webpack into the world. It revolutionized the way developers tie up their JS modules with its bundling prowess. Imagine all your script kiddies getting to play nice in a single sandbox, that's Webpack for you!
The Magic of 'Loaders' and 'Plugins'
In the mystical land of Webpack, 'Loaders' are like alchemists turning TypeScript into JavaScript or PNGs into data URLs, whereas 'Plugins' are the wizards casting spells to optimize your bundles or clean up the dist folder after production, making it more than just a packing tool; it's more like a Swiss Army knife for your code.
module.exports = {
module: {
rules: [
{ test: /\.txt$/, use: 'raw-loader' }
]
},
plugins: [
new Webpack.CleanPlugin()
]
};
Breaking the Time Continuum with HMR
Ever felt like a time traveler while coding? That's thanks to Webpack's Hot Module Replacement feature! Introduced in version 2, this nifty tool allows updates to be exchanged, added, or removed while an application is running, without a full reload. It's like Marty McFly touching up the past without busting the space-time continuum, making developer lives insanely easier, and visitors blissfully unaware of the tinkering going on behind the scenes.

Top 10 Webpack Related Tech
JavaScript
Let's kick things off with JavaScript, the bread and butter of web development. If Webpack were a rock band, JavaScript would be the lead guitarist, jamming away at the forefront. You see, without JavaScript, Webpack is like a toolbox without tools—pretty but pointless. JS is the scripting language that brings your code to life, making it dance, run, and sometimes cry when there's a bug.
console.log('Hello, Webpack!');
ES6 and Beyond
Think of ES6 as the evolved cousin of JavaScript—more bells and whistles, cleaner syntax sure to make developers' hearts flutter. It's like giving JavaScript a supercharged energy drink. Understanding ES6 is crucial because it plays nicer with Webpack, allowing you to write code that's both modern and less likely to make you pull your hair out.
const greet = () => console.log('ES6 makes JavaScript cooler!');
greet();
Node.js
Where would we be without Node.js? Probably crying in a corner. Node is like the stage crew for JavaScript's rock concert, enabling JS to perform outside the browser. With Node.js, Webpack can strut its stuff server-side, making it a must-have for your dev toolkit.
const http = require('http');
http.createServer((req, res) => {
res.write('Node.js world!');
res.end();
}).listen(8080);
NPM/Yarn
Ah, package managers—where would our project dependencies be without them? Lost in the void! NPM and Yarn are the librarians of Webpack's bookshelf, keeping all your lovely modules in order. They're like the butlers of the coding world, fetching whatever package your code's heart desires.
npm install webpack --save-dev
// or if you're fancy and prefer yarn
yarn add webpack --dev
Babel
Now, Babel is the wise old wizard of this whimsical web tale. It magically transmutes your ES6+ incantations back into plain, old-school JavaScript so that even the grumpiest of browsers can understand your modern spells.
{
"presets": ["@babel/preset-env"]
}
CSS Loaders
Prepare to meet your style maestros, the CSS Loaders! They slip nifty styles into your Webpack bundle with the grace of a ballet dancer. Ever seen a JavaScript file strut onto the scene in a dazzling CSS tuxedo? Thank CSS Loaders for that sartorial elegance.
module: {
rules: [
{
test: /\.css$/,
use: ['style-loader', 'css-loader']
}
]
}
React/Angular/Vue
Behold the trifecta of frameworks/libraries! Choosing one is like picking your favorite flavor of ice cream—there's no wrong answer (unless you pick something weird like mustard). These guys team up with Webpack to build you a snazzy, dynamic web application that could potentially take over the world… or at least look really cool.
import React from 'react';
import ReactDOM from 'react-dom';
ReactDOM.render(<h1>Hello, Webpack and React!</h1>, document.getElementById('app'));
Source Maps
Picture yourself lost in a maze of minified code—fear not! Source Maps are like your trusty map; they guide you back to the readable source code when debugging. They're the GPS for your coding road trip, ensuring you don't get lost in Minification Forest.
devtool: 'source-map'
Webpack Dev Server
The Webpack Dev Server is the life of the party—the DJ spinning your hot module replacement live! It's local development made easy, serving up your project on a platter and refreshing it every time you change the code, so you don't have to hit that refresh button like it owes you money.
devServer: {
contentBase: './dist',
hot: true
}
Code Splitting
Finally, we've got Code Splitting, the clever little trick that makes your app load faster than a kangaroo on a sugar rush. By splitting your code into bite-sized chunks, only the essential pieces are initially loaded, which means no more waiting around for the whole shebang. It's like getting your burger in stages: first the bun, then the patty, and the rest only if your tummy can handle it.
// Dynamic import syntax for code splitting
import("./math").then(math => {
console.log(math.add(16, 26));
});
