A Webpack loader for stylelint used with custom processors
I wrote this Webpack loader when I first encountered Styled Components and wanted to integrate my Styled Components Stylelint linting (using the
stylelint-processor-styled-components processor) into my Webpack setup so I could have it show up in my Hot Reloading (as shown in the gif above) etc. The loader I found was
stylelint-loader though, and it had been deprecated and was referring to
When should I use this loader?
If you just want to use normal Stylelint I would definitely suggest using the
postcss-loader instead of this package. This package was mainly written for Styled Components but also aims to support any other custom processor of Stylelint such as
First install the loader and stylelint with your favourite package manager
yarn add -D stylelint-custom-processor-loader
Or with npm
npm i -D stylelint-custom-processor-loader
This package will not work without stylelint as it is a peer dependency in the
package.json and it is just a development tool to connect webpack and stylelint together.
Stylelint config can be added as a file in the default way as seen in Stylelint's documentation. The recommended way is creating a
.stylelintrc file in the root of your project, but if you want to use a custom file path you can also use the configPath option.
This package currently only aims at supporting Webpack 2+.
If you are for example using Styled Components you could simply add the following to your webpack config:
module:rules:test: /\.jsx?/loader: 'stylelint-custom-processor-loader'exclude: /node_modules/
And you should now have linting your Styled Components css integrated with Webpack!
NOTE: You would of course have to install and use
stylelint-processor-styled-componentsas your custom processor in this example.
Webpack Babel Example
module:rules:test: /\.jsx?/use:'babel-loader''stylelint-custom-processor-loader'exclude: /node_modules/
NOTE: As always with Webpack loaders order can be very important, in general this loader should always be the first one loaded (which means the last one in the list) as seen above in the babel-loader example.
Give the path to a non-default named Stylelint config. The recommended way to specify it is in your Webpack config as follows:
module:rules:test: /\.jsx?/use:'babel-loader'loader: 'stylelint-custom-processor-loader'options:configPath: './path/to/stylelint/config'exclude: /node_modules/
Always return warnings if this option is set to
true. If you're using hot module replacement, you may wish to enable this in development, or else updates will be skipped when there's a stylelint error.
