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: Deploy to Heroku
  • 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
