Storybook for Server

---

Storybook for Server is a UI development environment for your plain HTML snippets rendered by your server backend. With it, you can visualize different states of your UI components and develop them interactively.

Storybook runs outside of your app. So you can develop UI components in isolation without worrying about app specific dependencies and requirements.

Getting Started

cd my-app
npx -p @storybook/cli sb init -t server

To configure the server that Storybook will connect to, export a global parameter parameters.server.url in .storybook/preview.js:

export const parameters = {
  server: {
    url: `http://localhost:${port}/storybook_preview`,
  },
};

The URL you connect to should have the ability to render a story, see server rendering below.

Writing Stories

To write a story, use whatever API is natural for your server-side rendering framework to generate set of JSON files of stories analogous to CSF files (see the server-kitchen-sink example for ideas):

{
  // Top level keys on the JSON file correspond to the default export in CSF
  "title": "Component",
  "parameters": {
    "options": { "component": "parameters" }
  },
  "stories": [
    {
      "name": "Default",
      "parameters": {
        // Provide an id here if you don't want to use SB's built in story ids.
        "server": { "id": "path/of/your/story" }
      }
    }
  ]
}

In your .storybook/main.js you simply provide a glob specifying the location of those JSON files, e.g.

module.exports = {
  stories: ['../stories/**/*.stories.json'],
};

Notice that the JSON does not specify a rendering function -- @storybook/server will instead call your parameters.server.url with the story's server id appended.

Ruby/Rails support

In particular the View Component::Storybook gem provides a Ruby API for easily creating the above with a Ruby/Rails DSL (as well as providing a server rendering endpoint).

Server rendering

The server rendering side of things is relatively straightfoward. When you browse to a story in the sidebar, Storybook will make a fetch request to \${parameters.server.url}/{parameters.server.id}`` and display the HTML that is returned.

So you simply need to ensure the route in your server app renders the appropriate HTML when called in that fashion.

Addon compatibility

Storybook also comes with a lot of addons and a great API to customize as you wish. As some addons assume the story is rendered in JS, they may not work with @storybook/server (yet!).

Many addons that act on the manager side (such as backgrounds and viewport) will work out of the box with @storybook/server -- you can configure them with parameters written on the server as usual.

Some addons work in specific ways:

Knobs

Note this functionality will likely be deprecated in favor of args support in the near future.

To configure knobs, add a special "knobs" key to the story JSON:

"knobs": [
  { "type": "text", "name": "Name", "value": "John Doe", "param": "name"},
  { "type": "number", "name": "Age", "value": 44, "param": "age"}
]

The knobs values will be added to your story URL as query parameters.

Actions

To use actions, use the parameters.actions.handles parameter:

"actions": {
  "handles": ["mouseover", "click .btn"]
}
