A way to pass an already generated GraphQLSchema to kitql and ignore modules?

[frankmayer]

Hi @jycouet

I would like to propose some way to pass an already generated GraphQLSchema to kitql and ignore the modules with their typedefs and resolvers.
I am currently researching

• Cruddl => "cruddl - create a cuddly GraphQL API for your database, using the GraphQL SDL to model your schema."
• for use with the Graph Database ArangoDB

Cuddle would automatically create (and also migrate on changes) the needed GraphDB Collections (nodes and edges) and all needed types and resolvers automatically based on the GraphQL SDL.
The only thing that is needed is to inject that cruddl-produced schema into graphql-yoga. I have tested this on a standalone yoga server and it works great, but it would be great if it would optionally be possible with kitql.
This would mean that we need a way to inject that schema into KitQL, so it can then inject that instead of the modules and also not bother with any schema merging of the modules.

Cruddle would be a perfect fit for people wanting to use ArangoDB and have a relatively easy (as also with KitQL) point of entry.

I might grow out of KitQL for this specific project and run a standalone Yoga server in that configuration, but I think it would still be an interesting option for people (and me 😄) to have.

What do you think?

Thanks for reaching out 👍.

It seems like a good use case. I would like to support a variety of ways of working.

I have a few questions to understand better:

• Once you put the schema, how fields will get resolved?
• Can't this be only a single module?

yep, I tried that, but it won't work. schema is of type GraphQLSchema... throws:

src/index.ts:74:22 - error TS2339: Property 'typeDefs' does not exist on type 'GraphQLSchema'.

74     typeDefs: schema.typeDefs,
                        ~~~~~~~~

src/index.ts:75:23 - error TS2339: Property 'resolvers' does not exist on type 'GraphQLSchema'.

75     resolvers: schema.resolvers
                         ~~~~~~~~~

src/index.ts:96:8 - error TS2339: Property 'listen' does not exist on type 'YogaNodeServerInstance<{ req: IncomingMessage; res: ServerResponse<IncomingMessage>; }, {}, {}>'.

96 server.listen(4000, () => {
          ~~~~~~

Do you know of any other way to create a module from a schema?

Would you create a repo with this so that I can have a look?
🙏 a lot

[frankmayer]

Yes I can do that. Will cook something up, tomorrow. It's a bit late now :) . I think you can also get away without installing ArangoDB. Cruddl also has an "InMemoryDB" we can use for tests. A DB is needed for the schema to be created, because of the automatic resolvers that have to be done especially for that DB.
🙏 Thank you very much

@jycouet got a repo with a scenario here. https://github.com/frankmayer/cruddl-graphql-modules-tests

[jycouet]

Thx a lot.
I'll have a look
