This is a simple tool allows you to deploy your Storybook into a static hosting service. (Currently, GitHub Pages only.)

Install Storybook Deployer with:

npm i @storybook/storybook-deployer --save-dev

Then add a NPM script like this:

{
  "scripts": {
    ...
    "deploy-storybook": "storybook-to-ghpages",
    ...
  }
}

Then you can run npm run deploy-storybook to deploy the Storybook to GitHub Pages.

If you customize the build configuration with some additional params (like static file directory), then you need to expose another NPM script like this:

{
  "scripts": {
    ...
    "build-storybook": "build-storybook -s public -o .out",
    ...
  }
}

Make sure to set the output directory as .out.

If you want to customize Git username, email or commit message, add this to package.json:

"storybook-deployer": {
  "gitUsername": "Custom Username",
  "gitEmail": "[email protected]",
  "commitMessage": "Deploy Storybook [skip ci]"
}

It will override the default configuration:

"storybook-deployer": {
  "gitUsername": "GH Pages Bot",
  "gitEmail": "[email protected]",
  "commitMessage": "Deploy Storybook to GitHub Pages"
}

To deploy Storybook to a remote other than origin, pass a --remote flag to npm run deploy-storybook.
For example, to deploy to your upstream remote:

npm run deploy-storybook -- --remote=upstream

Or, to specify a target branch and serve your storybook with rawgit instead of gh-pages:

npm run deploy-storybook -- --branch=feature-branch

Or, to specify a source branch other than master, pass a --source-branch flag to npm run deploy-storybook:

npm run deploy-storybook -- --source-branch=release
