what is babel and webpack

Difference between Webpack/Babel and react-scripts

stackoverflow.com › questions › 46337918 › difference-between-webpack-babel-and-react-scripts

Basically speaking, they serve different purposes and usually show up together. I will explain what they are designed to do.

babel

Babel is a transpiler. It can translate all kinds of high version ECMAScript ( not only ECMAScript, but it's easy to understand) into ES5, which is more widely supported by browsers (especially older versions). It's main job is to turn unsupported or cutting-edge language features into ES5.

Webpack

Webpack is, among other things, a dependency analyzer and module bundler. For example, if module A requires B as a dependency, and module B requires C as a dependency, then webpack will generate a dependency map like C -> B -> A. In practice it is much more complicated than this, but the general concept is that Webpack packages modules with complex dependency relationships into bundles. Regarding webpack's relationship with babel: When webpack processes dependencies, it must turn everything into javascript because webpack works on top of javascript. As a result, it uses different loaders to translate different types of resources/code into javascript. When we need ES6 or ES7 features, we use babel-loader to accomplish this.

react-scripts

when we start a react-based project, setting up the build environment is tough and time-consuming work. To help with this, the developers of React created an npm package called react-scripts that includes a lot of the basic setup most people will need for an average React app. Babel and webpack are included as dependencies in react-scripts

Webpack and Babel — What are they, and how to use them with React. | by Aswin G | Medium

December 20, 2019 - Webpack can also load non-js files, such as static assets, JSON files, CSS and more. Babel, on the other hand, is a JavaScript compiler, sort of. It doesn’t compile JavaScript the same way gcc compiles C++. Instead it compiles newer JavaScript into older JavaScript.

What does Webpack and Babel exactly do?

New features of the JavaScript language are constantly in development. Not all browsers have all these new features implemented. Babel allows you to write code using these new features and translates (transpiles) them back to an "older" version of JavaScript that all browsers understand. It also takes care of transpiling JSX to regular JS functions (so everytime your write , Babel transpiles this to React.createElement(MyComponent, {foo: 'bar'})). Webpack takes all the JS files of your React app, starting from the index.js root of your app, follows all the imported modules and bundles all files into a single bundle file. Other than JS, it can handle other file types like CSS, SVG, JSON by using so called 'loaders'. Loaders allow you to import these files directly in your JS module. When you create a Webpack build, it will output a HTML file that is linked to your JS bundle, ready to deploy on a webserver. Webpack uses the babel-loader to handle transpiling your JSX and JS files, like I described above. More on reddit.com

WebPack and react-scripts is slightly different things.

Webpack is used for compiling bundle for your web-application, which can be free-form and have some entry point. More then, webpack is used with babel-presets, which allows you to use modern ES6+ constructions in relative old browsers. Also, webpack is responsible for assembly dependent node_modules in one file, and maybe compress and optimise it. You can read more about webpack philosophy here: https://webpack.js.org/concepts/

React-scripts is just starter kit for launching some customized webpack-dev-server, which is configured to work with provided boilerplate for React playground. It's just demo purposes thing. Most modern web libraries has it's own starter kit, even server-side libraries too, e.g. https://github.com/reimagined/resolve/tree/master/packages/resolve-scripts and so on

Why and How to Use Webpack and Babel with Vanilla JS | Syncfusion Blogs

January 16, 2026 - So, for that, Webpack is an essential tool, as it analyses the files, creates a dependency graph, and bundles up the files in the best possible manner. Then, Webpack recursively explores all the files and identifies the dependencies. After that, it generates the minified output file and removes unnecessary assets. The whole process makes our Vanilla JS project easier to maintain and more efficient. Babel, in turn, translates the latest JavaScript code (ES6+) into older JavaScript code (ES5).

Webpack is a module bundler which packs all modules with dependencies js, styles, images, etc. into static assets .js, .css, .jpg , .png, etc. Webpack comes with presets which help for compilation into the required form. For example, react preset that helps to get the final output in react form, es2015 or env preset that helps to compile the code in ES5 or 6 or 7, etc. We have used babel 6 in the project setup.

Plus, we would like to minify and uglify both our CSS and Javascript code. Webpack solves all of these problems using one config file (named webpack.config.js) and one CLI command webpack.
