I've been reading up on GraphQL and how it makes querying easier than REST and reduces development time. I haven't yet found a way to set up GraphQL that isn't onerous and a huge amount of work. Found one system that came highly recommended but you still needed to write your database calls. Seriously? Is there a GraphQL system that you can point at your database, tell it how the foreign keys map and be up and running? All the articles have REST calls returning the contents of a single table - no matter how many rows. Is there any reason they're not returning the same sort of datasets as a GraphQL request?
Did you click on to where it says "Free Account"? I think it will send you to the free tutorial, then you just learn all you need to know.
I had a good look around but couldn't find anything about setting up or using graphql. Their content does look impressive for other topics. At the moment I'm thinking this looks right for me: https://api-platform.com/ I'm not sure why it took so long to find but proves that having the right domain doesn't really help SEO!
