hasura-realtime-poll

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

The Realtime Poll application is built using React and is powered by Hasura GraphQL Engine over Postgres. It has an interface for users to cast vote on a poll and the results are updated in the on-screen bar chart, 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.

Checkout the live app.
Explore the backend using Hasura Console.

Running the app yourself

Deploy GraphQL Engine on Hasura Cloud and setup PostgreSQL via Heroku:
Get the Hasura app URL (say realtime-poll.hasura.app)

Clone this repo:

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

Install Hasura CLI

Goto hasura/ and edit config.yaml:

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

Apply the migrations:

hasura metadata apply
hasura migrate apply
hasura metadata reload

Edit GRAPHQL_ENDPOINT in src/apollo.js and set it to the Hasura app URL:
```
export const GRAPHQL_ENDPOINT = "realtime-poll.hasura.app";
```
Run the app (go the root of repo):
```
npm install
npm start
```
