vue-pilot

Constructor

PathRouter

import Vue from 'vue'
import { PathRouter } from 'vue-pilot'

Vue.use(PathRouter)

const router = new PathRouter({
  routes: [
    // see routes definition below
  ],

  base: '/app/',
  origin: 'https://www.example.com/'
})

const app = new Vue({
  // inject the router instance
  router,
  
  // ...
})

router.start()

base: String. defines the base path of the app. If you want the root path not end with slash, you can set the base without ending slash, like '/app'. Defaults to ''.

origin: String | Array<String>. Let <RouterLink> treats absolute URLs with origin as in-app links.

HashRouter

import Vue from 'vue'
import { HashRouter } from 'vue-pilot'

Vue.use(HashRouter)

const router = new HashRouter({
  routes: [
    // ...
  ]
})

HashRouter doesn't have base option.

<RouterView>

The <RouterView> is a functional component that renders the matched component.

It has a name property. The default value is default.

Example:

<div id="app">
  <RouterView name="aside">
  <RouterView />
</div>

<RouterLink>

<RouterLink to="/list?page=1">List</RouterLink>
<RouterLink to="/home" target="_blank">Open new tab</RouterLink>

<RouterLink
  tag="div"
  action="replace"
  :to="{ path: '/category', query: { cat: 'shoes' }, state: { from: 'home' } }"
>
  Shoes
</RouterLink>

<RouterLink to="https://www.example.com">external link</RouterLink>

The <RouterLink> is a navigation component, it normally renders an <a> element.

to: Location object, or path/fullPath of the Location object, or an absolute URL.
action: String. push, replace, or dispatch. Defaults to push.
tag: String. The HTML tag name. Defaults to a.

<RouterLink> will have active class if it equals to the current path.

Location object

A location object is used for changing the current address. It can be used in <RouterLink :to="location">, router.start(location), router.push(location), router.replace(location), router.dispatch(location), etc.

A string URL can be converted to a location object by router.normalize(). And a location object can be converted to a URL string by router.url().

{
  path,
  external,
  query,
  hash,
  fullPath,
  url,
  state,
  hidden,
  appearPath
}

path

String

Router internal path, which has stripped the protocol, host, and base path.

external

Boolean

If path is started with protocal, or external is true, path is treated as an external path, and will be converted to an internal path.

query

Object | String | Array | URLSearchParams | StringCaster<URLSearchParams>

query accepts the same parameter types as URLSearchParams constructor. Or it can be a StringCaster object that wraps a URLSearchParams object.

hash

String

A string containing a # followed by the fragment identifier of the URL. If HashRouter is used, the fragment identifier is followed by the second # mark.

fullPath

String. Read-only.

path + query string + hash

url

String. Read-only.

An external relative URL which can be used as href attribute of <a>. It is the same as router.url(location).

PathRouter: base + path + query string + hash
HashRouter: # + path + query string + hash

state

Object

The state object is a JavaScript object which is associated with the history entry. See state parameter of history.pushState() for details.

hidden

Boolean

Indicate whether it is a hidden history entry. see router.push() for detail.

appearPath

String

If hidden is true and appearPath is set, the location bar will show this address instead.

Matched route object

A matched route object contains the information of the matched route. It contains some same properties as the Location object, and some extra properties. It's provided by the hook functions as the to and from parameter.

{
  path,
  query,
  hash,
  fullPath,
  url,
  state,
  params,
  meta
}

path

String

Same as location.path.

query

StringCaster

A StringCaster object that wraps a URLSearchParams object.

hash

String

Same as location.hash.

fullPath

String

Same as location.fullPath.

url

String

Same as location.url.

params

StringCaster

A StringCaster object that wraps a plain object. The plain object is collected from the path segments. See Routes definition below for details.

Routes definition

const routes = [
  {
    name: 'aside', // will be mounted into <RouterView name="aside">
    component: { /* component definition */ }
  },

  {
    path: '/basic',

    // Definition without `name`.
    // The component will be mounted into <RouterView name="default">
    component: { /* component definition */ }

    // Use `:paramName` to define params
    // More pattern syntax, see https://github.com/jiangfengming/url-router
    path: '/article/:id',

    // props can be a factory function, it receives the current route object as the first argument.
    props: route => ({
      articleId: route.params.int('id'),

      props: ['articleId', 'foo', 'bar'],
      // ...
    },

    // Setting key attribute of the <RouterView>.
    // It will re-create the component instead of reusing it when key changes.
    // So you needn't to watch the prop changes.
    // See https://vuejs.org/v2/api/#key
    // If key is a function, the returned value will be the key
    key: route => route.params.int('id')

          }
        }
      ]
    }
  ]
]

APIs

Most of the APIs are proxied to spa-history.

In the vue instance, you can get the router object from this.$router.

router.current

The current matched route object.

router.start()

router.start(URL string | location)

Starts the router.

In browser, if URL/location is not given, the default value is the current address.

router.normalize()

router.normalize(URL string | location)

converts the URL string or unnormalized location object to a normalized object.

if URL/location.path is started with protocal, or location.external is true, location.path is treated as an external path, and will be converted to an internal path.

// PathRouter with base '/foo/bar/'
router.normalize('http://www.example.com/foo/bar/home?a=1#b')
/*
  {
    path: '/home',
    query: new StringCaster(new URLSearchParams('a=1')),
    hash: '#b',
    fullPath: '/home?a=1#b',
    state: {}
  }
*/

// same result as above
router.normalize({
  path: '/foo/bar/home?a=1#b',
  external: true
})

// same result as above
router.normalize('/home?a=1#b')

// same result as above
router.normalize({
  path: '/home',
  query: {
    a: 1
  },
  hash: '#b'
})

// HashRouter
// same result as above
router.normalize('http://www.example.com/app/#/home?a=1#b')

The query property can be of type Object, String or Array. see URLSearchParams() for detail.

router.url()

router.url(URL string | location)

Converts an internal URL string or location object to an external relative URL which can be set as href attribute of <a>.

router.url({
  path: '/home',
  query: {
    a: 1
  },
  hash: '#b'
})

// or
router.url('/home?a=1#b')

/*
  result:
  HashRouter: #/home?a=1#b
  PathRouter(with base: '/foo/bar/'): /foo/bar/home?a=1#b
*/

router.push()

router.push(URL string | location)

Pushs the location onto the history stack. beforeChange event will be fired.

router.push('/home?a=1#b')

router.push({
  path: '/home',
  query: {
    a: 1
  },
  hash: '#b'
})

// PathRouter, complete URL
router.push('http://www.example.com/foo/bar/home?a=1#b')

// HashRouter, complete URL
router.push('http://www.example.com/#/home?a=1#b')

You can push a location with state.

router.push({
  path: '/home',
  state: {
    foo: 1,
    bar: 2
  }
})

And you can push a hidden location, which will not change the value of browser's address bar. the hidden location is stored in window.history.state

router.push({
  path: '/login',
  state: {
    foo: 1
  },

  // '/login' won't show in the location bar
  hidden: true,

  // optional. if set, the location bar will show this address instead
  appearPath: '/buy'
})

router.replace()

router.replace(URL string | location)

Replaces the current history entry with the location specified.

router.dispatch()

router.dispatch(URL string | location)

Dispatchs the route without changing the history. That is, the location of browser's address bar won't be changed.

router.setState()

router.setState(state)

Sets state of the current route. the state will be merged into router.current.state

router.go()

router.go(position, { silent = false, state = null } = {})

Counterpart of window.history.go(). Returns a promise which will be resolved when popstate event fired.

silent: if true, beforeChange event won't be fired.

state: if set, the state object will be merged into the state object of the destination location.

router.back()

router.back(options)

Alias of router.go(-1, options)

router.forward()

router.forward(options)

Alias of router.go(1, options)

router.captureLinkClickEvent()

router.captureLinkClickEvent(event)

Prevents the navigation when clicking the <a> element in the container and href is an in-app address, router.push() will be called instead.

<div @click="$router.captureLinkClickEvent($event)">
  <a href="/foo">foo</a>
</div>

router.on()

router.on(event, callback, { once = false, beginning = false })

Adds a callback function that will be called when the specified event fires.

If once is true, the callback function will be removed after

If beginning is true, the callback function will be inserted at the beginning of the callback array, so it will be called first.

router.off()

router.off(event, callback, { once = true })

Removes the specified event callback.

Events

beforeChange

router.on('beforeChange', function(to, from, action, router) {
  // ...
})

The beforeChange hook will be called before confirming the navigation. this refers to the router instance.

Arguments

to: Route object. The route will be changed to.
from: Route object. The current route.
action:
- push: router.push() is called.
- replace: router.replace() is called.
- init: "to" is the initial page, at this stage, "from.path" is null.
- pop: user clicked the back or foraward button , or router.go(), router.back(), router.forward() is called, or hash changed.
- dispatch: router.dispatch() is called.
router: the router instance

Returns

The hook can return one of the following values, or a promise that resolves with one of the following values, to control the navigation:

true | undefined: The navigation is confirmed.
false: Prevent the navigation.
null: Do nothing.
location: Redirect to this location. You can override the history manipulate action by providing location.action property, values are: 'push', 'replace', 'dispatch'.

beforeUpdate

router.on('beforeUpdate', function(to, from, action, router) {
  // ...
})

The beforeUpdate hook will be called after the history has been changed but before updating the <RouterView>s. this refers to the router instance.

Returning false or a promise that resolves with false can prevent to update the <RouterView>s.

afterChange

router.on('afterChange', function(to, from, action, router) {
  // ...
})

The afterChange hook will be called after <RouterView>s have been updated. this refers to the router instance.

Dependencies

You can use @babel/polyfill and dom4 to meet the requirements.

Or use the polyfill.io service:

<script src="https://polyfill.io/v3/polyfill.min.js"></script>
