Storybook Branch switcher
A Storybook 7+ addon to navigate between multiple Git branches. Also a command-line tool to automatically generate one instance per branch.
Installation
Install the following module with npm:
npm i --save-dev storybook-branch-switcher
or with yarn:
yarn add -D storybook-branch-switcher
Then, add following content to .storybook/main.js
module.exports = {
addons: ["storybook-branch-switcher"],
};
CLI
This package exports a script called sb-branch-switcher
which will automatically generate one Storybook instance per
branch, based on your Git workflow. (We support Git submodules, and any checkouts will only run in a clean workspace.)
Configuration
The CLI needs a configuration file located at .storybook/.branches.json
by default. But you can create this file in
another location and pass the path to the CLI with the --config
or --c
argument.
Example : sb-branch-switcher --config libs/storybook-host/.storybook/.branches.json

FAQ
How do I host my storybook in a subpath? (e.g. GitHub Pages)
Out-of-the-box this addon supports hosting Storybook at the root path, but you'll need some extra setup if you'd like to host a storybook in a subpath.
| ✅ Out-of-the-box: root path | 🛠️ Requires setup: subpaths |
|:-----------------------------|:--------------------------------------------|
| http://localhost:6006
| http://localhost:6006/some/path

| https://sub.example.com
| https://your-username.github.io/your-repo

Just make these changes in your .storybook/preview.js
file, in this example,
publishing to GitHub Pages.

export default preview;
You'll then just need to set STORYBOOK_PUBLISH_FOR_WEB=true
in whatever build
environment you run the sb-branch-switcher
command.
To test locally:
- set
hostname
in.storybook/preview.js
tolocalhost:6006/storybook-bundle
, - build via
STORYBOOK_PUBLISH_FOR_WEB=true sb-branch-switcher <other opts>
- run
npx http-server dist
to serve your local storybook one subpath deeper.
