Boiler plate to test graphql subscriptions using nodejs

Boilerplate to test GraphQL subscriptions using nodejs

Although it takes just a few lines of code to set up your NodeJS code to use GraphQL subscriptions, it does involve going through a few pages of docs. We've put together a few lines of boilerplate code to make it easy to get started.

Usage:

• Reference code: Refer to index.js for the boilerplate code that sets up a GraphQL subscription observable.

• Dependencies: This uses the apollo link, subscription-transport-ws libraries. npm install --save graphql graphql-tag apollo-link apollo-link-ws subscriptions-transport-ws ws

Try it out:

• Use hasura as a test backend:
• Create a table author with columns id: integer, name: text
• Set the GraphQL endpoint in index.js to https://HEROKU_APP_NAME.herokuoapp.com/v1alpha1/graphql
• git clone https://github.com/hasura/nodejs-graphql-subscriptions-boilerplate.git
• cd nodejs-graphql-subscriptions-boilerplate
• npm i
• node index.js
• Now head to the Hasura console and insert an author with id: 1, name: honeysingh
• Changes will appear on your nodejs code
• Edit the row on the console
• Changes will appear on your nodejs code
