Differences with vue-router

Things we improve:

• New lifecycle method navigate() that can return a Promise. The router will wait for that promise to be resolved before loading the view.
• Can enable a route when the navigate method fails to load an error screen.
• Hooks after a view is really loaded, after navigate finishes.
• There is a single hook navigate() called every time the view is loaded, even if it's the same. No more separate beforeRouteEnter and beforeRouteUpdate with the same implementation copy pasted in different functions.

Things that remain the same:

• Same names for the components (<router-view> and <router-link>)
• Parameters and catch-all (aka not found) views the same as vue-router.
• It has the same this.route and this.router objects to control the routing though individual methods and properties may vary. They aren't prefixed by $ though.

Things not implemented in this repo:

• No nested router views.
• No lazy loading of components.
• No global hooks.

Usage example

In the src/demo folder there is a complete working example. The main part of the code is the registration of this plugin in the src/demo/demo.js file:

import { createApp } from 'vue'

import Hermes from '@altipla/hermes'

import routes from './demo/routes'
import AppLayout from './demo/AppLayout.vue'


let app = createApp(AppLayout)
app.use(Hermes, { routes })
app.mount('#app')

The routes file should by convention export the whole list of URLs registered in the application:

import Home from './views/Home.vue'
import Simple from './views/Simple.vue'
import Params from './views/Params.vue'
import Search from './views/Search.vue'
import Reload from './views/Reload.vue'
import ThrowError from './views/ThrowError.vue'
import Delayed from './views/Delayed.vue'
import Error from './views/Error.vue'
import NotFound from './views/NotFound.vue'


export default [
  { path: '/', component: Home },
  { path: '/simple', component: Simple },
  { path: '/params/:foo', component: Params },
  { path: '/search', component: Search },
  { path: '/reload', component: Reload },
  { path: '/throw-error', component: ThrowError },
  { path: '/delayed', component: Delayed },
  { path: '[error]', component: Error },
  { path: '*', component: NotFound },
]

Finally the view is the same as in vue-router, use a component:

<template>
  <div>
    <h1>Simple View</h1>
    <h4>Back: <router-link to="/">Home View</router-link></h4>
  </div>
</template>

<script>
export default {
  async navigate() {
    await myService.LoadAnything();
  },
}
</script>

Things you can do with this lib

Route params

export default [
  { path: '/params/:foo', component: Params },
]

<template>
  <div>
    <h1>Params View</h1>
    <p>{{route.params}}</p>
    <h4>Back: <router-link to="/">Home View</router-link></h4>
  </div>
</template>

<script>
export default {
}
</script>

Programmatic navigation

this.router.navigate('/myroute');

Composition API

import { useRouter, useRoute } from '@altipla/hermes'


export default {
  setup() {
    let router = useRouter()
    let route = useRoute()

    ...
  },
}

Search parameters

If you access /search?foo=bar this view will show bar inside the paragraph:

export default [
  { path: '/search', component: Search },
]

<template>
  <div>
    <h1>Search View</h1>
    <p>{{route.search}}</p>
    <h4>Back: <router-link to="/">Home View</router-link></h4>
  </div>
</template>

<script>
export default {
}
</script>
