Requested fields for a type? about graphqlite HOT 2 CLOSED

Hello crirus! For example, the client has this Query:

Products (id:20) {
Price,
Name,
BrandName
}

The Query will return JSON with this Fields: Price, Name and Brand Name. But if client wants only name, the Query must be:

Products (id:20) {
Name
}

The Customer/Client will choose what to return by the Query. The Application, in the resolver, must populate with data from Database/File, etc

Hey @crirus!

@jmurrayrs answer is correct. The whole purpose of GraphQL is to let you fetch exactly the fields you need. If this is not obvious to you, maybe you can take a look at the main GraphQL tutorial.

Now, I feel that you already know that and that your question is rather: "is there a way to get in advance the list of fields that I will have to resolve"?
And I also guess you are asking because your backend is a database and you would like to fetch only the columns that will be needed instead of fetching all the columns? Am I correct?

If this is what you are trying to do, we added in GraphQLite 4 a new way to access the GraphQL request.
GraphQLite is built on top of the webonyx/graphql-php. This library comes with a "ResolveInfo" object that contains information related to the requested fields.

You can now type-hint on ResolveInfo in any resolver.

See documentation here:

https://graphqlite.thecodingmachine.io/docs/next/query-plan

Please note this is only available in GraphQLite 4. It is not yet tagged stable but will be in less than a month, and I don't expect any more breaking changes, so you can start using GraphQLite 4 right now.
