If you’re currently using babel-loader, make the following change to your : module.exports = option set to ensure we can process JSX/TSX.įinally, we’ll swap out using Terser for JavaScript minification for esbuild as well.
#BABEL LOADER INSTALL#
First, install the dependency: npm i -D esbuild-loader It’s very straightforward to migrate a project that uses either babel-loader or ts-loader to esbuild-loader. This walkthrough will explore using esbuild-loader in your webpack setup. As such, esbuild-loader represents a middle ground - and an early way to get access to the increased build speed that esbuild offers without saying goodbye to webpack. While esbuild may not work for all use cases, it will work for the majority of tasks.

However, I feel strongly that the important thing here is developer productivity. To declare an interest here for full disclosure, I’m the primary maintainer of ts-loader, a popular TypeScript loader that is commonly used with webpack. It allows users to swap out ts-loader or babel-loader with itself, which massively improves build speeds. Developed by hiroki osame, esbuild-loader is a webpack loader built on top of esbuild. There’s a relatively new project named esbuild-loader. So if your team wants to have faster builds but doesn’t have the time to go through a big migration, is there anything you can do? Yes, there’s a middle ground to be explored. It’s battle-tested on large projects, it’s mature, and it handles a wide range of use cases. There’s a reason webpack is so popular it does a lot of things very well indeed. New projects might start with Vite, but existing ones are less likely to be ported. Migrating to a new build tool is no small task.

There are a lot of projects out there that are already heavily invested in their current build tooling - mostly webpack. In the long term, the likes of esbuild, Vite, and friends may well come to displace the current standard build tools - the webpacks, rollups, and so on. These new tools are transformative and likely represent the future of build tooling for the web. This translates into significantly faster builds. Go and Rust enjoy far better performance than JavaScript. The significant difference between these and their predecessors is that the new-school tools are written in languages like Go and Rust. The new kids on the blog are tools like esbuild, Vite, and swc. These tools are written in the same language they compile to - namely, JavaScript or TypeScript. It’s long been common practice to run your JavaScript and TypeScript through some kind of Node.js-based build tool like webpack or rollup.js. With apologies to those suffering from JavaScript fatigue, the world of web development is evolving yet again.
#BABEL LOADER HOW TO#
In this tutorial, we’ll show you how to use esbuild alongside webpack with esbuild-loader. However, if you’re invested in webpack but would still like to take advantage of speedier builds, there is a way.

We need to define some rules around what should be transformed here. This is actually what we should expect at this point because we need to add one other step to this.

So let's go ahead and run our build command which will run webpack and even though it looks like some transpiling has occurred, nothing is really happening yet. And finally we're going to add another object here called use and we're going to say that this should use the babel-loader. We can also define an optional key for exclude and this is just going to say don't run babel on the node modules folder 'cause that will take a long time. Now this test key is going to say that whenever a JavaScript file is found, babel should transpile it. The next thing we want to do here is add an object and we're going to add a test key. We're going to add another key here called module and we're going to add another called rules. Next we're going to need to adjust the nfig. And both are going to be added to our package json. Babel-loader is the loader, babel/core is the actual babel package that handles the transformations. Let's go to our terminal and we're going to, install babel-loader and also and we're going to save these to our dev dependencies. To set up the babel-loader, we'll need to take a few steps.
