vue-router-fetch

Declarative fetching - move data fetching from your components to the router!

• no fetching code inside of your components - focus on presentation and UX rather than some infrastructure code
• no beforeRouteEnter, beforeRouteUpdate guards to fetch data
• no need to maintain ref or reactive states
• no need for a store (Vuex, Pinia etc.)
• URL string is all you need in simplest scenario

Fetures

• Declarative fetching in the router
• Route parameters support
• Reactive fetching state
• Tiny - around 1kB thanks to native fetch
• Easily configurable
• Custom fetch function support

Instalation

npm i vue-router-fetch

💡 vue-router is a peer dependency so make sure its installed as well.

// main.js
import routerFetch from 'vue-router-fetch'
...
app.use(routerFetch, { router });

Usage

Single fetch

// router.js
{
  path: '/',
  meta: {
    fetch: 'https://632f9c11f5fda801f8d41dd6.mockapi.io/foos'
  }
}

Results will be available under data variable:

<template>
  <h2>Foos</h2>
  <ul>
    <li v-for="item in data">{{item.name}}</li>
  </ul>
</template>
<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { data } = useRouteFetch()
</script>

Named fetch

Use named fetch when you need to fetch multiple things:

// router.js
{
  path: '/',
  meta: {
    fetch: {
      foos: 'https://632f9c11f5fda801f8d41dd6.mockapi.io/foos',
      bars: 'https://632f9c11f5fda801f8d41dd6.mockapi.io/bars'
    }
  }
}

Results will be available under corresponding variables :

<template>
  <h2>Foos</h2>
  <ul>
    <li v-for="item in data.foos">{{item.name}}</li>
  </ul>

  <h2>Bars</h2>
  <ul>
    <li v-for="item in data.bars">{{item.name}}</li>
  </ul>
</template>
<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { data } = useRouteFetch()
</script>

Custom fetch

Provide your custom fetch function when you need to do a bit more than just hit the URL:

// router.js
{
  path: '/',
  meta: {
    fetch: () => {
      ...
      return myApi.fetchFoos(...)
    }
  }
}

💡 Custom fetch functions are available in single and named mode.

Parameters

vue-router-fetch can use route parameters with your fetch url as long as they have a matching name:

// router.js
{
  path: '/home/:id',
  meta: {
    fetch: 'https://632f9c11f5fda801f8d41dd6.mockapi.io/foos/:id'
  }
}

You can use route params with a query string as well:

// router.js
{
  path: '/home/:id',
  meta: {
    fetch: 'https://632f9c11f5fda801f8d41dd6.mockapi.io/foos?id=:id'
  }
}

Fetching state

Every fetch that you configured will have fetching state that you can use inside your template (ie. show/hide a loader).

Single fetch:

<template>
  <h2>Foos</h2>
  <ul v-if="!fetching">
    <li v-for="item in data">{{item.name}}</li>
  </ul>
</template>
<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { data, fetching } = useRouteFetch()
</script>

Named fetch:

<template>
  <h2>Foos</h2>
  <ul v-if="!fetching.foos">
    <li v-for="item in data.foos">{{item.name}}</li>
  </ul>

  <h2>Bars</h2>
  <ul v-if="!fetching.bars">
    <li v-for="item in data.bars">{{item.name}}</li>
  </ul>
</template>
<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { data, fetching } = useRouteFetch()
</script>

Response

In case you need to access ie. status code etc. useRouteFetch will also expose reactive response for single an every named fetch.

Single fetch:

<template>
  <h2>Foos</h2>
  <h3>Status: {{response.status}}</h3>
  <ul>
    <li v-for="item in data">{{item.name}}</li>
  </ul>
</template>
<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { data, response } = useRouteFetch()
</script>

Named fetch:

<template>
  <h2>Foos</h2>
  <h3>Status: {{response.foos.status}}</h3>
  <ul>
    <li v-for="item in data.foos">{{item.name}}</li>
  </ul>

  <h2>Bars</h2>
  <h3>Status: {{response.bars.status}}</h3>
  <ul>
    <li v-for="item in data.bars">{{item.name}}</li>
  </ul>
</template>
<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { data, response } = useRouteFetch()
</script>

Manual fetch

useRouteFetch returns fetch function/object so you fetch from your component. This is specially usefull when you need to ie. refetch after some write operation:

// router.js
{
  path: '/',
  meta: {
    fetch: {
      foos: 'https://632f9c11f5fda801f8d41dd6.mockapi.io/foos',
      bars: 'https://632f9c11f5fda801f8d41dd6.mockapi.io/bars'
    }
  }
}

<template> ... </template>
<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { data, fetch } = useRouteFetch()

  function refreshEverything() {
    fetch()
  }
  function refreshFoos() {
    fetch.foos()
  }
</script>

Manual methods

Applications are more than just fetching data so useRouteFetch exposes get, post, patch, put and del (delete) methods that you can call directly.

<template> ... </template>
<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { get, post, del, patch } = useRouteFetch()

  del('https://632f9c11f5fda801f8d41dd6.mockapi.io/foos/6')
    .then(({ data, response }) => { ... })
</script>

Every method returns a promise that will resolve an Object with data (json data from a reponse) and response if you need access to full reponse.

post, push and put accept a payload to send as a second argument:

<script setup>
  import { useRouteFetch } from 'vue-router-fetch'
  const { post, patch } = useRouteFetch()

  post('https://632f9c11f5fda801f8d41dd6.mockapi.io/foos', { name: 'new foo' })
    .then(({ data, response }) => { ... })

  patch('https://632f9c11f5fda801f8d41dd6.mockapi.io/foos/6', { name: 'update' })
    .then(({ data, response }) => { ... })
</script>

Custom fetch options

You can pas your configuration to fetch method on a global and per route basis

Global

app.use(RouterFetch({ fetchOptions: { method: 'POST' } }))

That includes your static headers:

app.use(RouterFetch({ fetchOptions: { headers: { 'x-something': 'foo' } } }))

and dynamic headers, ie. authentication token:

app.use(RouterFetch({ fetchOptions: { headers: () => { 'authentication': ... } } }))

Per route

Same configuration can be passed to each route:

// router.js
{
  path: 'foo',
  meta: {
    fetch: 'some.url',
    fetchOptions: {
      method: 'POST',
      headers: { 'x-something': 'foo' }
    }
  }
}

💡 Route options will override global one!
