    gatsby-plugin-less

    Provides drop-in support for Less stylesheets

    Install

    npm install gatsby-plugin-less

    How to use

    1. Include the plugin in your gatsby-config.js file.
    2. Write your stylesheets in Less and require or import them as normal.
    // in gatsby-config.js
    plugins: [`gatsby-plugin-less`]

    If you need to pass options to the Less loader use the loaderOptions and to Less use lessOptions object; see less-loader for all available options.

    // in gatsby-config.js
    plugins: [
      {
        resolve: `gatsby-plugin-less`,
        options: {
          loaderOptions: {
            appendData: `@env: ${process.env.NODE_ENV};`,
          },
          lessOptions: {
            strictMath: true,
            plugins: [new CleanCSSPlugin({ advanced: true })],
          },
        },
      },
    ]

    If you need to override the default options passed into css-loader Note: Gatsby is using css-loader@^5.0.0.

    // in gatsby-config.js
    plugins: [
      {
        resolve: `gatsby-plugin-less`,
        options: {
          cssLoaderOptions: {
            camelCase: false,
          },
        },
      },
    ]

    With CSS Modules

    Using CSS modules requires no additional configuration. Simply prepend .module to the extension. For example: app.less -> app.module.less. Any file with the module extension will use CSS modules. CSS modules are imported as ES Modules to support treeshaking. You'll need to import styles as: import { yourClassName, anotherClassName } from './app.module.less'.

    PostCSS plugins

    PostCSS is also included to handle some default optimizations like autoprefixing and common cross-browser flexbox bugs. Normally you don't need to think about it, but if you'd prefer to add additional postprocessing to your Less output you can specify plugins in the plugin options

    // in gatsby-config.js
    plugins: [
      {
        resolve: `gatsby-plugin-less`,
        options: {
          postCssPlugins: [somePostCssPlugin()],
        },
      },
    ]
