Discussion on: REST API OR GraphQL

As the others said, it depends on requirements and needs.

Taking from GraphQL vs REST: Overview:

• Most of us don't do REST, we do RESTish (the hypermedia part is left out in many, many, APIs, mine included)
• If you are not using hypermedia then GraphQL is a good alternative
• File uploading is easier in REST than in GraphQL
• Deprecation is easier in GraphQL
• GraphQL is better for asking only a subset of a full resource (because you can ask only the fields you need)
• REST plays better with caching at all levels (proxies and all). GraphQL transfers caching to the client and cannot use HTTP caching headers.
• GraphQL is better at introspection (you don't have to design the schema of the API, it's implicit in the definition)
• Filtering is hard in both
• Sending different responses for different clients is way easier in GraphQL (which is one of the reasons Github migrated to it)

I don't think they can be pitted against in every case, it really depends on what you need. You can also use both as it's suggested in the article :)
