Introduction

This is the official Quasar app extension for adding GraphQL to your Quasar project.

This AE uses Apollo Client and Vue Apollo.

Installation

quasar ext add @quasar/apollo

NOTE: As of 2.1.0-beta.1, version 2 is now in the dev and default branch of the repository. It is also the version you'll get with the "normal" @quasar/apollo package. No need to use @next tag anymore.

IMPORTANT Since version 2.2.0-beta.2 we externalized all deps for this AE: graphql, graphql-tag, @apollo/client and @vue/apollo-composable. If you installed a previous version, rerun quasar ext add @quasar/apollo command to have compatible deps added to your project's package.json.

Version 1 has been deprecated and is no longer supported. If you wish to use it, you can install it with @quasar/apollo@1.0.0-beta.8.

Quasar CLI will retrieve the extension from NPM (@quasar/quasar-app-extension-apollo)

The extension will add a configuration file into src/apollo and a boot file. You'll need to manually register the latter into quasar.conf.js > boot.

Prompts

You will be prompted if you wish to use GraphQL subscriptions, if you answer yes, you will be prompted which subscription transport you wish to use. Available options are:

After selecting the transport, the necessary dependencies will be installed and the initialization code will be scaffolded for you.

Uninstall

quasar ext remove @quasar/apollo

You might also wish to remove the added directory src/apollo and related boot file.

Apollo client options

Apollo client options can be customized in src/apollo/index.(ts|js).

You will need either to set the GraphQL endpoint in it, or set it as an environment variable before running Quasar:

GRAPHQL_URI=https://prod.example.com/graphql quasar build
GRAPHQL_URI=https://dev.example.com/graphql quasar dev

If you don't have a GraphQL endpoint yet, you can create one to experiment with at FakeQL or other similar services.

If you are using GraphQL subscriptions, you will also need to set the WebSocket endpoint as an environment variable:

GRAPHQL_URI=https://prod.example.com/graphql GRAPHQL_WS_URI=wss://prod.example.com/graphql quasar build
GRAPHQL_URI=https://dev.example.com/graphql GRAPHQL_WS_URI=wss://dev.example.com/graphql quasar dev

You can use dotenv in quasar.config file to set these environment variables in a more convenient way, if you wish.

Usage

Check the guide in Vue Apollo docs.

Example usage:

src/pages/Index.vue

<template>
  <q-page class="row items-center justify-evenly">
    <div v-if="loading">Loading...</div>
    <div v-else-if="error">Error: {{ error.message }}</div>
    <div v-else-if="result && result.post">
      <div>id: {{ result.post.id }}</div>
      <div>title: {{ result.post.title }}</div>
    </div>

    ...
  </q-page>
</template>

<script setup lang="ts">
import { useQuery } from '@vue/apollo-composable'
import { gql } from '@apollo/client/core'

const { result, loading, error } = useQuery(gql`
  query getPosts {
    post(id: "3") {
      id
      title
    }
  }
`)

Multiple apollo clients setup

Un-comment the relevant code in boot/apollo.(ts|js)

The following is an example using clientA instead of the default client:

// ...
const { result, loading, error } = useQuery(
  gql`
    query getPosts {
      post(id: "3") {
        id
        title
      }
    }
  `,
  null,
  { clientId: 'clientA' },
)
// ...

Tooling

An apollo.config.js configuration file for Apollo GraphQL VSCode extension ((apollographql.vscode-apollo)) will be automatically scaffolded.

You should fill in the client.service.url property with the URL of the server exposing your GraphQL schema, check client.service documentation to learn about other options.

This extension will automatically connect to your remote server, read your GraphQL schema and provide autocomplete/schema errors detection for your GraphQL queries.
