svelte with graphql

A sample Svelte 3 app to demonstrate usage of GraphQL Queries, Mutations and Subscriptions with svelte-apollo, Hasura GraphQL engine and Postgres as database. Forked from the standard svelte template

Deploy Hasura

• 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) and created_at

• Now create a relationship from article table to author table by going to the Relationships tab.

Setup App

Install the dependencies...

npm install

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

  const wsLink = new WebSocketLink({
    uri: "ws://localhost:8080/v1/graphql",
    options: {
      reconnect: true,
      lazy: true
    },
    connectionParams: () => {
      return { headers: getHeaders() };
    },
  });

  const httpLink = new HttpLink({
    uri: "http://localhost:8080/v1/graphql",
    headers: getHeaders()
  });

Replace the uri argument with your Hasura GraphQL Endpoint for both wsLink and httpLink

Start Rollup:

npm run dev

Navigate to localhost:5000. You should see your app running. Edit a component file in src, save it, and reload the page to see your changes.

Deploying to the web
