quasar-framework-vue-graphql

Boilerplate to get started with Quasar Framework, Hasura GraphQL engine as CMS and postgres as database using the quasar-cli and vue-apollo module.

Tutorial

• Deploy GraphQL Engine on Hasura Cloud and setup PostgreSQL via Heroku:

  

• Get the Hasura app URL (say quasar-graphql.hasura.app)

• Create author table:

  Open Hasura console: visit https://quasar-graphql.hasura.app on a browser Navigate to Data section in the top nav bar and create a table as follows:

  

• Insert sample data into author table:

  

  Verify if the row is inserted successfully

  

• Similarly, create an article table with the following data model: table: article columns: id, title, content, author_id (foreign key to author table's id)

• Clone this repo:

  git clone https://github.com/hasura/graphql-engine
  cd graphql-engine/community/sample-apps/quasar-framework-vue-graphql
  

• Install node modules:

  yarn install
  

• Open src/plugins/apollo.js and configure Hasura's GraphQL Endpoint as follows:

import { ApolloClient } from 'apollo-client'
import { InMemoryCache } from 'apollo-cache-inmemory'
import VueApollo from 'vue-apollo'
import fetch from 'node-fetch'
import { createHttpLink } from 'apollo-link-http'

const httpLink = createHttpLink({ uri: 'https://quasar-graphql.hasura.app/v1/graphql', fetch: fetch })

// Create the apollo client
const apolloClient = new ApolloClient({
  link: httpLink,
  cache: new InMemoryCache(),
  connectToDevTools: true
})

In the httpLink, replace quasar-graphql.hasura.app with your own URL of Hasura Cloud Project.

• We have defined the graphql query for fetching author list in src/layouts/MyLayout.vue.

  • GraphQL query

  const authorQuery = gql`
    query {
      author {
        id
        name
      }
  }`
  

  • In pages/Articles.vue, we have defined a graphql query for articles

  
  <script>
  const articleQuery = gql`
    query articleQuery($authorId: Int!) {
      article(where:{author_id: {_eq: $authorId}}) {
        id
        title
        content
      }
    }`
  export default {
    data () {
      return {
        authorId: this.$route.params.authorId
      }
    },
    name: 'Articles',
    apollo: {
      // Simple query that will update the 'article' vue property
      article: {
        query: articleQuery,
        prefetch: false,
        variables () {
          return { authorId: this.authorId }
        }
      }
    },
    watch: {
      '$route.params.authorId': {
        handler: function (authorId) {
          if (this.$apollo.queries.article) { this.$apollo.queries.article.refetch({ authorId: authorId }) }
        },
        deep: true,
        immediate: true
      }
    }
  }
  </script>
  
  

• Run the app:

  quasar dev
  

• Test the app Visit http://localhost:8080 to view the app
