After reading the API docs about nested mutation (https://www.prisma.io/docs/reference/prisma-api/mutations-ol0yuoz6go#nested-mutations), i'm a little lost on how I could write resolvers for nested mutation in the application layer... Does anyone have learning resource(s) for this ? 🤔

are you familiar with writing resolvers for "simpler" mutations using

prisma-binding

already? 🙂

I would say I understand the basics, that

prisma-binding

pass the generated schema from

prisma.graphql

to the context argument of each resolver functions.

ok 🙂 you can see one possible way of writing a nested mutation in your own resolver here: https://github.com/graphql-boilerplates/node-graphql-server/blob/master/advanced/src/resolvers/Mutation/post.js#L4-L19

Than you nilan for this example 👍. Seems pretty forward when it comes to

connect

to schema's Types, but when you need to

create

or

update

multiple nodes, what the

args

should look like ? Can we pass array to arguments of a mutation ?

the JS spread operator will come in handy in this case 🙂

Oh yes you're right. It seems essential for this. Do you know if I can do something like this in my schema definition ?

type Mutation {
 newUser(name: String!, posts: [Post!]!): User!
}

It throws me an error

must be Input Type but got: [Post!]!.

you cannot 🙂 please look into the generated

prisma.graphql

file for the

createUser

mutation and use the input type used there

Ooooh okay ! Now I get it. Awesome🔥 Thank you so much nilan for your time 🙂
