Storybook is architected to support diverse web frameworks, including React, Vue, Angular, Web Components, Svelte, and over a dozen others. This guide helps you get started on adding new framework support for Storybook.
Scaffolding a new framework
The first thing to do is to scaffold your framework support in its own repo.
We recommend adopting the same project structure as the Storybook monorepo. That structure contains the framework package (
app/<framework>) and an example app (
examples/<framework>-kitchen-sink) as well as other associated documentation and configuration as needed.
It may seem like a little more hierarchy than what’s necessary. But because the structure mirrors the way Storybook’s monorepo is structured, you can reuse Storybook’s tooling. It also makes it easier to move the framework into the Storybook monorepo later if that is desirable.
We recommend using
@storybook/html as a starter framework since it’s the simplest and contains no framework-specific peculiarities. There is a boilerplate to get you started here.
Supporting a new framework in Storybook typically consists of two main aspects:
Configuring the server. In Storybook, the server is the node process that runs when you run
storybook build. Configuring the server typically means configuring babel and webpack in framework-specific ways.
Configuring the client. The client is the code that runs in the browser, and configuring it, means providing a framework-specific story rendering function.
Configuring the server
It's helpful to understand Storybook's package structure before adding a framework preset. Each framework typically exposes two executables in its
These scripts pass an
options object to
@storybook/core/server, a library that abstracts all of Storybook’s framework-independent code.
For example, here’s the boilerplate to start the dev server with
Thus the essence of adding framework presets is just filling in that options object.
As described above, the server
options object does the heavy lifting of configuring the server.
Let’s look at the
@storybook/vue’s options definition:
The value of the
framework option (i.e., ‘vue’) is something that gets passed to addons and allows them to do specific tasks related to your framework.
The essence of this file is the framework presets, and these are standard Storybook presets -- you can look at framework packages in the Storybook monorepo (e.g. React, Vue, Web Components) to see examples of framework-specific customizations.
While developing your custom framework, not maintained by Storybook, you can specify the path to the location file with the
You can add a relative path to
frameworkPath. Don't forget that they resolve from the Storybook configuration directory (i.e.,
.storybook) by default.
Make sure the
frameworkPath ends up at the
dist/client/index.js file within your framework app.
Configuring the client
To configure the client, you must provide a framework-specific render function. Before diving into the details, it’s essential to understand how user-written stories relate to what renders on the screen.
Storybook stories are ES6 objects that return a “renderable object.”
Consider the following React story:
In this case, the renderable object is the React element,
Consider the following hypothetical example:
The design of this “renderable object” is framework-specific and should ideally match the idioms of that framework.
The framework's render function is the entity responsible for converting the renderable object into DOM nodes. It is typically of the form:
On the client side, the key file is
The globals file typically sets up a single global variable that client-side code (such as addon-provided decorators) can refer to if needed to understand which framework it's running in:
start function abstracts all of Storybook’s framework-independent client-side (browser) code, and it takes the render function we defined above. For examples of render functions, see React, Vue, Angular, and Web Components in the Storybook monorepo.
