Build A Live News API with Apollo Server V4 Subscriptions and GraphQL (TypeScript Tutorial)

In this video we dive deep into Apollo Server V4 subscriptions and using the graphql-ws library to create a scalable Apollo Server API that allows users to view live events. This video is perfect for anyone looking to create any system that requires live data and is just the start to what you can create using powerful technologies such as subscriptions. This is also a great introduction to GraphQL and what GraphQL looks like when working with Apollo Server typedefs and resolvers.

[martinapincione]

Hello, I am able to successfully make a mutation but when I do subscriptions I get a status error saying it's unable to connect to the ws://localhost:4000/graphql. Do you know what might be causing this issue? I even tried cloning you git code and running it on my local machine with no success

Send a POST request to query this endpoint:

curl --request POST \
--header 'content-type: application/json' \
