access resolvers' grandparent params in graphQL middleware - graphql

Question

I'm performing this query
query MyQuery($roomId: String, $closetId: String, $caseId: String) {
room(roomId: $roomId) {
closet(closetId: $closetId){
case(caseId: $caseId)
}
}
}
I have a middleware applied to case where i need to perform a test on the first parent's arg roomId
I'm using the library https://www.npmjs.com/package/graphql-middleware
export const globalMiddleware = async (resolve, root, args, context, info) => {
console.log(args.caseId)
console.log(root.closetId)
console.log(grandparent.roomId) // !!!!!!!!!!!!
// ... do something
return await resolve(root, args, context, info)
}
I can access its own arg caseId with args.caseId
I can access its direct parent's arg closetId with root.closetId
Question :
How do I access its first parent's arg roomId ??
PS: the code is ultra simplified, in my real code i have many more resolvers, nested on deeper levels. Which means that passing manually the argument roomId to every reslver is not a practical solution
I could go with accessing only the first parent's args though

Answer 1

It looks like the way it's build, there is no direct way to access resolver's grand-parent/first-parent.
One way to solve this is by passing all the query's params to the context:
const server = new ApolloServer({
schema: schemaWithMiddleware,
context: async ({ req }) => {
return {
variables: req.body.variables
}
}
})
this way you can access all of the params in all resolvers:
export const globalMiddleware = async (resolve, root, args, context, info) => {
console.log(context.variables.roomId)
// ... do something
return await resolve(root, args, context, info)
}
