Vite-plugin-vue-gql NPM

Why?

When writing Vue clients for GraphQL APIs, I've noticed scripts in Vue SFC files have become over-filled with GraphQL queries and had a need to organize the code better without taking away from what makes SFCs great: Having all the code for a single component organized and in one place.

Moving queries to their own files would then create multiple files for a single component, cluttering the project more and reducing productivity in having to write components spanning multiple files.

Enter Vue GQL! I wrote this Vite plugin to allow placing GraphQL queries related to a component directly within the component file without cluttering scripts, by placing them within their own specialized \<gql> tags.

⚠️ This Plugin is still in Development and currently only works with the <script setup> format

Install

# Install Plugin
npm i -D vite-plugin-vue-gql

# Install Peer Dependicies
npm i @urql/vue graphql

// vite.config.ts

import Vue from '@vitejs/plugin-vue'
import Vql from 'vite-plugin-vue-gql'

export default {
  plugins: [
    Vue(), 
    Vql()
  ],
}

If you are using typescript, make sure you include the following in your tsconfig.json

{
  "compilerOptions": {
    "types": [
      "vite-plugin-vue-gql/client"
    ]
  }
}

Usage

Instead of import your functions from @urql/vue you should now import them from the vql package.

import { useQuery, useMutation, useSubscription } from 'vql'

<gql> tags can have the following attributes, query(not required), mutation, subscription, and name. The first three attributes indicates what type of query it is while the name attribute allows you to have multiple queries in the same Vue SFC.

<!-- Query-->
<gql></gql>

<!-- Mutation -->
<gql mutation></gql>

<!-- Subscription -->
<gql subscription></gql>

<!-- Named GQL Block -->
<gql name="users"></gql>

Examples

Basic Usage

<script setup lang="ts">
import { useQuery } from 'vql'

const { data } = useQuery()
</script>

<template>
  <h1>{{ data.hello }}</h1>
</template>

<gql>
{
  hello
}
</gql>

Query with Variables

<script setup lang="ts">
import { ref } from 'vue'
import { useQuery } from 'vql'

const name = ref('Evan')
const { data } = useQuery({ variables: { name } })
</script>

<template>...</template>

<gql>
query($name: String!) {
  user(name: $name) {
    username
  }
}
</gql>

Named Query

<script setup lang="ts">
import { ref } from 'vue'
import { useQuery } from 'vql'

const name = ref('Evan')
const { data } = useQuery('users', { variables: { name } })
</script>

<template>...</template>

<gql name="users">
query($name: String!) {
  user(name: $name) {
    username
  }
}
</gql>

Mutations

<script setup lang="ts">
import { ref } from 'vue'
import { useMutation } from 'vql'

const { executeMutation } = useMutation()
</script>

<template>...</template>

<gql mutation>
mutation($name: String!) {
  createUser(name: $name) {
    username
  }
}
</gql>

Subscriptions

<script setup lang="ts">
import { ref } from 'vue'
import { useSubscription } from 'vql'

const isPaused = ref(false)
const handleSubscription = (messages = [], response) => {
  return [response.newMessages, ...messages]
}

const { data } = useSubscription({ from: 'Eren' }, { pause: isPaused }, handleSubscription)
</script>

<template>...</template>

<gql mutation>
subscription MessageSub($from: String!) {
  newMessages(from: $from) {
    id
    from
    text
  }
}
</gql>

Fragments

You can use fargments in your graphql queries, mutations, and subscriptions by specifying your .gql files that contain your fragments in the config.

// vite.config.ts

import Vue from '@vitejs/plugin-vue'
import Vql from 'vite-plugin-vue-gql'

export default {
  plugins: [
    Vue(), 
    Vql({
      fragments: './src/fragments/**/*.gql'
    })
  ],
}

Here is a general idea of what your fragments should look like

# src/fragments/albums.gql

fragment albumFields on Album {
  id
  name
  image
}

Finally you can use these fragments in your Vue SFC

<script setup lang="ts">
import { ref } from 'vue'
import { useQuery } from 'vql'

const name = ref('RADWIMPS')
const { data } = useQuery({ variables: { name } })
</script>

<template>...</template>

<gql>
query($name: String!) {
  queryArtists(byName: $name) {
    name
    image
    albums {
      ...albumFields
    }
  }
}
</gql>
