> Gatsby works with CSS Modules by default, no need for extra plugins. You should only use this if you already know what babel-plugin-react-css-modules is and want to enable it for your project.

gatsby-plugin-react-css-modules

Transforms styleName to className using compile time CSS module resolution.
See the
babel-plugin-react-css-modules README
for details.

Install

npm install gatsby-plugin-react-css-modules

How to use

``javascript
// In your gatsby-config.js
plugins: [
{
resolve: gatsby-plugin-react-css-modules,
options: {
// *.css files are included by default.
// To support another syntax (e.g. SCSS),
// add postcss-scss to your project's devDependencies
// and add the following option here:
filetypes: {
".scss": { syntax: postcss-scss },
},

// Exclude global styles from the plugin using a RegExp:
exclude: \/global\/,
// For all the options check babel-plugin-react-css-modules README link provided above
},
},
]
`

Files must be named using the pattern filename.module.css` for Gatsby to treat
them as CSS modules. You can change this behavior using a custom webpack config
