storybook-vue3-router

Storybook Vue3 Router

A Storybook decorator that allows you to use your Vue 3 routing-aware components.

If you want to build stories for Vue 3 components using <router-view> or <router-link> then you need to wrap your stories with vue-router this addon will allow for you to easily do this.

How to use

This decorator works with Storybook's Component Story Format (CSF) and hoisted CSF annotations, which is the recommended way to write stories since Storybook 6. It has not been tested with the storiesOf API.

Install the decorator

npm install --save-dev storybook-vue3-router
// or
yarn add --dev storybook-vue3-router

Use in your stories

The default setup will create a vue-router instance, with 2 routes (/ and /about) - these can be reviewed in the defaultRoutes.ts file.

/* import storybook-vue3-router */
import vueRouter from 'storybook-vue3-router'

/* ...story setup... */

/* your story export */
export const Default = Template.bind({})

/* adding storybook-vue3-router decorator */
Default.decorators = [
  /* this is the basic setup with no params passed to the decorator */
  vueRouter()
]

Demo

You can see the examples stories published on this demo.

Advanced usage

This decorator comes with optioal params for customising the implementation of your vue-router within Storybook.

Custom Routes

/* define our custom routes */
const customRoutes = [
  {
    path: '/',
    name: 'home',
    component: HomeComponent // this would need to be defined/imported into the `.stories` file
  },
  {
    path: '/about',
    name: 'about',
    component: AboutComponent // this would need to be defined/imported into the `.stories` file
  }
]

/* adding storybook-vue3-router decorator */
Default.decorators = [
  /* pass custom routes to the decorator */
  vueRouter(customRoutes)
]

Custom Routes (with guards)

/* define our custom routes */
const customRoutes = [
  // ...
  {
    path: '/admin',
    name: 'admin',
    component: AdminComponent,
    /* add per-route navigation guard */
    beforeEnter: (to, from, next) => {
      // ...
    }
  }
]

/* adding storybook-vue3-router decorator */
Default.decorators = [
  /* pass custom routes to the decorator */
  vueRouter(customRoutes)
]

Custom Routes (with inital route)

By default the decorator will default the starting route to /, if you want to change this you can pass as a parametor to the decorator

/* define our custom routes */
const customRoutes = [
  {
    path: '/',
    name: 'dashboard',
    component: Dashboard
  },
  {
    path: '/intro',
    name: 'intro',
    component: Intro
  }
]

/* adding storybook-vue3-router decorator */
Default.decorators = [
  /* pass initialRoute to the decorator */
  vueRouter(customRoutes, {
    initialRoute: '/intro'
  })
]

See the examples folder for more advanced usage.

Decorator Parameters

function vueRouter(routes: RouteRecordRaw[], options?: { initialRoute?: string, beforeEach?: NavigationGuard })

v2.x Migration

The migration from v1 brings some breaking changes:

// v1.x - 2nd param is used to pass `beforeEach` router guard
// in this example the guard is used to fire a storybook action with `to` and `from` router objects
vueRouter(customRoutes, (to, from) => action('ROUTE CHANGED')({ to: to, from: from })) // LEGACY

// v2.1 - 2nd param is used to pass additional options to the decorator
vueRouter(customRoutes, {
  /* add global beforeEach guard */
  beforeEach: (to, from) => action('ROUTE CHANGED')({ to: to, from: from })
})

If you were previously using v1 with router guards in the second parameter, these will need to be refactored to use the route specific router guards (recommended) or you can pass your global route guards using the beforeEach option.

v2.0 DOES NOT HAVE THIS beforeEach option, please upgrade to v2.1

⚠️ Warning:

When using the global beforeEach option, if there is an existing story also using this decorator then we must force a page reload in order to setup the specific story router guard and this has a minor UX / performance impact. Checkout the demo for an example of this: README > With Router Guards > Global Guard - when clicking the 'Global Guard' link you will notice the page is refreshed to apply global guards (due to previously existing stories).

This will not be an issue if you are using this decorator for just one story.

After resolving this issue, to enable multiple stories to be created using different route setups, it was noticed that this caused the global beforeEach function to be added on every route. For example every time you click a different story the new beforeEach hook is added - but previous ones are not removed, this results in multiple guards firing on stories unrelated to the 'active' story.
