Better Programming

GraphQL is a trendy technology that solves specific problems related to data fetching and allows for better data querying and manipulation. However, it also comes with challenges such as performance optimization, typing complexity, tooling support, and security concerns. The decision to adopt GraphQL should be based on careful consideration of business requirements and the maturity of the ecosystem.

GraphQL: From Excitement to Deception

Sadly, there are a lot of technical flaws in this article.
REST does not have an official spec at all so that is a strength of Graphql.
Monitoring graphql and/or deprecated field is possible. You can even monitor every step of processing a graphql request from parsing to validation to executions.
there can be other clients that are not web clients, other services for example that may need different data.
if you call a service from a resolver and it can identify books of being a part of the query you would usually make a join over books and have a single query.
You can also restrict query depth and costs as a security measure.
Also, handling errors in production, you would probably mask them as a security measure too.
And if you understand Graphql errors more like Either monads that guarantee a response of either err or data, that concept is not new I’d say.

I felt this article was pretty balanced. I’ve tried to use Graphql for numerous things. The API and schema feel ok but never as good as the hyper.
