I am learning graphql & prisma and I came across a question on prisma subscription.
I want to return an item list whenever there is a creation or update on Item. So this is my code which not works.
scheme.graphql
# import Item from "./generated/prisma.graphql"
type Subscription {
todoItems: TodoItems
}
type TodoItems {
items: [Item!]!
}
resolver
const Subscription = {
todoItems: {
subscribe: async (parent, args, context, info) => {
const itemSubscription = await context.db.subscription.item({
where: { mutation_in: ['CREATED', 'UPDATED'] },
}, info);
return itemSubscription;
},
resolve: async (payload, args, context, info) => {
const items = await context.db.query.items({ type: 0, orderBy: 'updatedAt_DESC' }, info);
return { items };
},
},
}
module.exports = {
Subscription,
}
and in graphql playground,
subscription{
todoItems{
items{
title
}
}
}
it gives the error:
{
"errors": [
{
"message": "Anonymous Subscription must select only one top level field.",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"todoItems"
],
"extensions": {
"code": "INTERNAL_SERVER_ERROR",
"exception": {
"stacktrace": [
"Error: Anonymous Subscription must select only one top level field.",
" at asErrorInstance (d:\git\inote\node_modules\graphql\execution\execute.js:489:43)",
" at <anonymous>",
" at process._tickCallback (internal/process/next_tick.js:118:7)"
]
}
}
}
]
}
Any idea?

Prisma does not support subscribing item lists. Instead, prisma wants you to subscribe to single item mutations ("created", "updated", "deleted"). As described here.
E.g.
subscription newTodos {
todo(where: {
mutation_in: [CREATED]
}) {
mutation
node {
title
}
}
}
To get "the full list", you have to query on the todos after subscribing to avoid missing events (race condition). As a result you have to manually "sync" the data from the subscription and your query.
