HOW TO USE GRAPHQL SUBSCRIPTION

This repo is using

• rails
• graphql-ruby
• apollo2
• ActionCable

JUST TRY IT OUT

git clone https://github.com/github0013/graphql_subscription_actioncable.git
cd graphql_subscription_actioncable
rails s

then open http://localhost:3000/. You should only see this.

Open another terminal and run

rails c

> GraphqlSubscriptionActioncableSchema.subscriptions.trigger('testSub', {}, Time.now.to_i)

then you should see a timestamp number on the page.

THINGS TO CHECK WHEN YOU IMPLEMENT GRAPHQL SUBSCRIPTION

• check ActionCable's allowed origins
• check cable.yml be sure to use anything other than adapter: async
• don't just copy GraphqlChannel sample as is. It needs some changes.

check the git log

I kept commands I ran in the log. It should self-explanatory.
