- Webpack is a "module bundler". On its own it does not change the source of a program (note: there are some caveats to this, e.g. minification), only join all the different bits of a large codebase together for easier and more efficient delivery over the Internet (depending on the use case; you may be bundling server-side code, in which case the benefits are mostly around being able to consolidate build tooling).
- A webpack loader is used to process files during bundling. It is specific to webpack (you would not use
babel-loaderwithout webpack, except maybe in cases of interop with other build tools, but even then it would not be used on its own). - In a webpack configuration one specifies a mapping of file extensions to webpack loaders. For example, a common case is to process
.tsfiles usingts-loader. This way, webpack will pass off files with the.tsextension to the TypeScript compiler, and use the output of this compilation in the bundle, instead of the source program. - Babel is a compiler; it takes an ESNext program and produces an equivalent ES3+ compatible program.
babel-loaderdoes whatts-loaderdoes for TypeScript; passes off files to the Babel compiler, and returns the result to be used in the bundle in-place of the original source program.
Isn't transpiling and bundling is a separate process?
Yes. That is why we have "webpack the bundler", and "Babel the compiler/transpiler", and babel-loader to connect the two together. Without babel-loader webpack would not be able to process files through Babel.
Hope that helps.

December 24, 2021Are Babel and Webpack used often TOGETHER or is it 'one or the other'?
Webpack is capable of doing all kinds of preprocessing on files. Babel converts es6 code. Webpack has a kind of plug-in system called "loaders". Each loader can do a different kind of preprocessing. So babel-loader is one instance of a webpack loader someone wrote that uses babel, but there are also lots of other kinds of loaders like react-loader, css-loader, etc. Also, usually these loaders are based on standalone libraries because webpack isn't the only bundling option out there. So for example I'm pretty sure you can use babel on it's own to process files. There are other preprocessors like grunt, gulp, rollup, broccoli, etc. and they all have their own separate babel based plugins and plugin ecosystem. More on reddit.com

December 20, 2019 - Loaders are plugins for Webpack that are used for preprocessing files before they are bundled by webpack. For .js and .jsx files, we tell Webpack to use babel-loader which makes Webpack run these files through Babel before bundling them.

When set, each Babel transform output will be compressed with Gzip. If you want to opt-out of cache compression, set it to false -- your project may benefit from this if it transpiles thousands of files. customize: Default null.

Since you already have to make a new file to use this, it is recommended that you instead use .custom to create a wrapper loader.

These options are only allowed as part of Babel's programmatic options, so they are primarily for use by tools that wrap around Babel, or people calling babel.transform directly. Users of Babel's integrations, like babel-loader or @babel/register are unlikely to use these.

I'm bundling with webpack and normally I use ts-loader for ts files and babel for js
{
test: /\.jsx?$/,
use: 'babel-loader',
exclude: /node_modules/
},
{
test: /\.tsx?$/,
use: 'ts-loader',
exclude: /node_modules/
}But I've noticed a lot of tutorial use babel-loader for both and just adding @babel/preset-typescript to .babelrc
{
test: /\(.jsx?|.tsx?)$/,
use: 'babel-loader',
exclude: /node_modules/
},
//.babelrc
plugins: ["@babel/preset-env", "@babel/preset-typescript"]Do y'all go for approach #1, #2 or something else entirely?

I use esbuild , also works with the node cli using esbuild-register node -r esbuild-register index.ts. It doesn't do type checking though, only compiling, so you need to run typescript separately or in your IDE. you can also use it with webpack (I never tried it though)

January 18, 2021 - Under rules we have test, which lets us decide which files qualify for bundling. In this case we use regex to specify files that end with .js. In exclude, we declare that we do not want to bundle our node_modules. Use is where we bring Babel into the picture by setting our loader as babel-loader.

Demystifying Webpack Loaders: A Deep Dive into Babel Loader | by Fortun | Medium
November 18, 2024 - Webpack, on the other hand, doesn’t understand JavaScript syntax directly — it simply takes input files and processes them using loaders and plugins. Babel Loader integrates Babel into Webpack’s build pipeline, allowing you to transpile JavaScript code while bundling your project.

r/learnjavascript on Reddit: Are Babel and Webpack used often TOGETHER or is it 'one or the other'?
July 30, 2018 -
I know what Babel does but I see tutorial videos on Webpack and it seems that it is Webpack which backdates the code to pre-ES5 and it miniaturises it as well. It was unclear whether that is something which you need Babel for so Webpack can do it automatically or if Webpack has that feature built-in independent from Babel and it's a matter of picking one tool or the other to ensure your code works on such-and-such an edition of IE.
Again, I am aware of what each tool accomplishes. But not how they both work together, if they work together, and which tool has what particular duty when they are being used. It's all very abstract. How do professional developers use Babel and Webpack, if they decide to?

Webpack is a bundler. Babel is a compiler/transpiler (ES5 to ES6). They are pretty much always used together.
