Storybook displays your components in a custom web application built using webpack. Webpack is a complex tool but our default configuration is intended to cover off the majority of use cases. There are also addons available that extend the configuration for other common use cases.
You can customize Storybook's webpack setup by providing a
webpackFinal field in
The value should be an async function that receives a webpack config and eventually returns a webpack config.
By default, Storybook's webpack configuration will allow you to:
You can import images and other local files and have them built into the Storybook:
You can import
If you want to know the exact details of the webpack config, the best way is to run:
To extend the above configuration, use the
webpackFinal field of
The value should export a
function, which will receive the default config as its first argument. The second argument is an options object from Storybook, this will have information about where config came from, whether we're in production of development mode etc.
For example, here's a
.storybook/main.js to add Sass support:
Storybook uses the config returned from the above function to render your components in Storybook's "preview" iframe. Note that Storybook has a completely separate webpack config for its own UI (also referred to as the "manager"), so the customizations you make only applies to the rendering of your stories, i.e. you can completely replace
config.module.rules if you want.
config with care. Make sure to preserve the following config options:
config requires the
HtmlWebpackplugin to generate the preview page, so rather than overwriting
config.plugins you should probably append to it (or overwrite it with care), see the following issue for examples on how to handle this:
Finally, if your custom webpack config uses a loader that does not explicitly include specific file extensions via the
test property, it is necessary to
.ejs file extension from that loader.
If you're using a non-standard Storybook config directory, you should put
main.js there instead of
.storybook and update the
include path to make sure that it resolves to your project root.
If you have an existing webpack config for your project and want to reuse this app's configuration, you can import your main webpack config into Storybook's
.storybook/main.js and merge both:
The following code snippet shows how you can replace the loaders from Storybook with the ones from your app's
