Do HNers believe GraphQL will become the new REST?
Is GraphQL just a new fad that will come and go?
Are you using GraphQL in production or thinking about it?
If you are using GraphQL in production, what language or framework are you running on? I heard Sangria works well and there's the nodeJS versions.
Is there something better than REST and GraphQL?
GraphQL solves a number of different issues and is particularly good on the front end, but the ability to write/update data is more limited.
RPC is still a very valid technology, and suits event architectures very well. It's incredibly flexible, but that means you need to spend more time designing a good API.
Choose the best approach for the problem at hand.
