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.

There is also a mocked router decorator option for users who only need access to $route and $router properties.

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.

Storybook v6: Please use package version 2.x

Storybook v7: Please use package version 3+

See migration guides.

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 initial route)

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

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

### With Router Options
We can pass [Vue Router options](https://router.vuejs.org/api/index.html#history) into our decorator.

```typescript
/* adding storybook-vue3-router decorator */
Default.decorators = [
  /* pass vueRouterOptions to the decorator */
  vueRouter(undefined, {
    vueRouterOptions: {
      linkActiveClass: 'my-active-class',
      linkExactActiveClass: 'my-exact-active-class'
      ...etc
    }
  })
]

router.isReady()

If you have a router setup using router.isReady() and / or you have components which require specific route / route data on created lifecycle hook you may need to use the asyncVueRouter export.

This export provides router which won't render story until router is ready.

Story setup

import { asyncVueRouter } from 'storybook-vue3-router'

/* 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 */
  asyncVueRouter(customRoutes, {
    initialRoute: '/intro'
  })
]

Preview.js Async Setup

In order to use async router setup method, you will need to amend your .storybook/preview.js file to wrap stories in Vue 3's <Suspense> component. This is because the decorator requires an async setup() to correctly await router.isReady(). You can modify preview to:

const preview = {
  decorators: [
    (story) => ({
      components: { story },
      template: '<Suspense><story /></Suspense>',
    }),
  ],
};

export default preview;

See the examples folder for more advanced usage.

Decorator Parameters

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

Mock Router

The full vue-router is not always needed - for example if you don't have components using <router-view> or <router-link> then using the mockRouter export may cover your needs (and reduce the imports being used in your stories).

Note: mockRouter will only work in instances where you are using options API this.$route and/or this.$router, it is not suitable for use-cases using vue router composables such as useRoute() and useRouter().

Use mockRouter in your stories

The default setup will create mock $router and $route from vue-router, this allows you to create stories for components using programatic navigation and route based logic.

We can also pass custom options into the mockRouter decorator:

{ 
  meta?: Array<string>, 
  params?: Array<string>, 
  query?: Array<string>
}

/* import storybook-vue3-router mockRouter */
import { mockRouter } from 'storybook-vue3-router'

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

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

/* adding storybook-vue3-router mockRouter decorator */
Default.decorators = [
  mockRouter({
    meta: ['some_meta'],
    params: ['some_param'],
    query: ['some_query']
  })
]

You can see examples of the mockRouter in our storybook demo site, and our code examples

v2.x > v3+ Migration

⚠️ BREAKING CHANGE ⚠️

v3.x version no longer uses default export for vueRouter decorator, you will need to update to using named import:

/* DONT */
import vueRouter from 'storybook-vue3-router'
/* DO */
import { vueRouter } from 'storybook-vue3-router'

v1.x > 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.
