customize-cra-less-loader

Add less loader to any create-react-app using customize-cra. Support with css-loader v3.

Only support react-scripts version >= v5.0.0.

If PR 255 been merged into master, you don't need this modules

Usage

First, install customize-cra-less-loader, less and less-loader packages:

npm i -D customize-cra-less-loader less less-loader
// or yarn add --dev customize-cra-less-loader less less-loader

After it's done, call addLessLoader in override like below:

const { override } = require("customize-cra");
const addLessLoader = require("customize-cra-less-loader");

module.exports = override(addLessLoader(loaderOptions));

loaderOptions is optional. If you have Less specific options, you can pass to it. For example:

const { override } = require("customize-cra");
const addLessLoader = require("customize-cra-less-loader");

module.exports = override(
  addLessLoader({
    cssLoaderOptions: {
      sourceMap: true,
      modules: {
        localIdentName: "[hash:base64:8]",
      },
    },
    lessLoaderOptions: {
      lessOptions: {
        strictMath: true,
      },
    },
  })
);

Check Less document for all available specific options you can use.

Once less-loader is enabled, you can import .less file in your project.

And .module.less will use CSS Modules.

if you use TypeScript (npm init react-app my-app --typescript) with CSS Modules, you should edit react-app-env.d.ts.

declare module "*.module.less" {
  const classes: { [key: string]: string };
  export default classes;
}
