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 Postgres and GraphQL Engine on Heroku:

Please checkout our docs for other deployment methods
Get the Heroku app URL (say my-app.herokuapp.com)
Create author table:

Open Hasura console: visit https://my-app.herokuapp.com 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/nuxtjs-postgres-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://myapp.herokuapp.com/v1alpha1/graphql', fetch: fetch })

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

In the httpLink, replace myapp.herokuapp.com with your own Heroku URL of Hasura GraphQL Engine.

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
