realtime-location-app

A demo application to showcase real-time capabilities of Hasura GraphQL Engine.

Edit realtime-location-tracking

The Realtime location application is built using React and is powered by Hasura GraphQL Engine over Postgres. It has an interface for users to track location of a vehicle using Hasura live queries, in real-time.

The application makes use of Hasura GraphQL Engine's real-time capabilities using subscription. There is no backend code involved. The application is hosted on GitHub pages and the Postgres+GraphQL Engine is running on Postgres.

Running the app yourself

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

    Deploy to Hasura Cloud

  • Get the Hasura app URL (say realtime-backend2.hasura.app)

  • Clone this repo:

    git clone https://github.com/hasura/graphql-engine
cd graphql-engine/community/sample-apps/realtime-location-tracking

  • Install Hasura CLI

  • Goto hasura/ and edit config.yaml:

    endpoint: https://realtime-backend2.hasura.app

  • Apply the migrations:

    hasura metadata apply
hasura migrate apply
hasura metadata reload

  • Edit HASURA_GRAPHQL_ENGINE_HOSTNAME in src/constants.js and set it to the Hasura app URL:

    const HASURA_GRAPHQL_ENGINE_HOSTNAME = 'realtime-backend2.hasura.app/v1/graphql';

  • Run the app (go to the root of the repo):

    npm start
