The Vite builder cannot build itself. Are you willing to contribute?

storybookjs#11

Please read the How to contribute guide.

Installation

npm install storybook-builder-vite --save-dev

or

yarn add --dev storybook-builder-vite

Usage

In your main.js configuration file, set core: { builder: "storybook-builder-vite" }.

For autoreload of stories to work, they need to have .stories.tsx file suffix. See also #53

The builder supports both development mode in Storybook, and building a static production version.

Customize Vite config

The builder will not read your vite.config.js file by default.

In .storybook/main.js (or whatever your Storybook config file is named) you can override the Vite config:

module.exports = {
  async viteFinal(config, { configType }) {
    // customize the Vite config here
    config.resolve.alias.foo = 'bar';

    // return the customized config
    return config;
  },
  // ... other options here
};

The viteFinal function will give you config which is the builder's own Vite config. You can tweak this as you want, for example to set up aliases, add new plugins etc.

The configType variable will be either "DEVELOPMENT" or "PRODUCTION".

The function should return the updated Vite configuration.

Svelte Customization

When using this builder with Svelte, your .storybook/main.js (or equivalent) can contain a svelteOptions object to pass custom options to vite-plugin-svelte:

const preprocess = require('svelte-preprocess');

module.exports = {
  svelteOptions: {
    preprocess: preprocess({
      typescript: true,
      postcss: true,
      sourceMap: true,
    }),
  },
};

Note about working directory

The builder will by default enable Vite's server.fs.strict option, for increased security. The default project root is set to the parent directory of the storybook configuration directory. This can be overridden in viteFinal.

Getting started with React, Vite and Storybook (on a new project)

npm init @vitejs/app vite-react-app --template react && cd vite-react-app
npm install # or yarn
npx sb@next init --builder storybook-builder-vite && npm run storybook

Known issues

• HMR: saving a story file does not hot-module-reload. In svelte, the page is not reloaded either (storybookjs#209). HMR should work when saving component files.
• Prebundling: Vite restarts if it detects new dependencies which it did not know about and needs to pre-bundle. This breaks within storybook, with confusing error messages. If you see a message in your terminal like [vite] new dependencies found:, please add those dependencies to your optimizeDeps.include in viteFinal. E.g. config.optimizeDeps.include = [...(config.optimizeDeps?.include ?? []), "storybook-dark-mode"],.
• MDX pages are broken when emotion 11 is installed: Adding the configuration here should fix this.

About this codebase

The code is a monorepo with the core storybook-builder-vite package, and examples (like packages/example-react) to test the builder implementation with.

Similar to the main storybook monorepo, you need yarn , because the project is organized as yarn workspaces. This lets you write new code in the core builder package, and instantly use them from the example packages.
