Why you should try GraphQL?

We used it for a b2b backend system with a lot of configurable knobs that change data entry drastically.

It meant that we had almost no possibility in caching anything so we saw a good fit in Graphql. Especially when 3th parties need an API you can easily give them the Graphql and they can query what they need.

We used it in a rails app with a react frontend. Depending on the requirements, GraphQL can bring more problems to the table than solutions
