Current behavior
Hello,
I'm using the graphql example( in the example directory of nest) with the Cat CRUD and i try to use a union type and interface but i didn't find a way to do it.
When i try to request my data with a fragment, i have the following error :
"Abstract type MutationResult must resolve to an Object type at runtime for field Mutation.createCat with value "[object Object]", received "undefined". Either the MutationResult type should provide a "resolveType" function or each possible types should provide an "isTypeOf" function."
There is nothing in the doc explaining how to use union / interface, and there is nothing in the graphql example.
In the apollo documentation, the type resolver ( here "Cat" Resolver") should implement a __resolveType function. I tried to set this function in the @resolver('Cat') class CatsResolvers
but it's not working.
I tried to add it on the cat resolvers class
Expected behavior
The request should return either a Cat item or GraphQLErrorItem from my schema definition.
Minimal reproduction of the problem with instructions
export interface GraphQLError {
readonly message: string;
readonly errorCode: number;
readonly type: string;
}
type GraphQLError {
message: String
errorCode: Int
type: String
}
union MutationResult = Cat | GraphQLError
- change the createCat Mutation in the schema
- createCat(name: String, age: Int): MutationResult
- add the function in cats.resolvers.ts in the CatsResolvers class
__resolveType(obj, context, info): string{
return obj.errorCode ? 'GraphQLError' : 'Cat';
}
What is the motivation / use case for changing the behavior?

Hi guys,
I started to use the GraphQL module and I must say that it is awesome. However, I had some difficulties to perform POST requests against my GraphQL endpoints (GET requests works out of the box).
I'm using the following packages:
"dependencies": {
"@nestjs/common": "^4.5.4",
"@nestjs/core": "^4.5.4",
"@nestjs/graphql": "^2.0.0",
"@nestjs/microservices": "^4.5.3",
"@nestjs/testing": "^4.5.4",
"@nestjs/websockets": "^4.5.3",
...
"apollo-server-express": "^1.3.2",
"graphql": "^0.11.7",
"graphql-tools": "^2.11.0",
...
}
Here is my GraphQL module implementation, according to the Nestjs documentation:
import {Module, NestModule, MiddlewaresConsumer, RequestMethod} from '@nestjs/common';
import {graphqlExpress, graphiqlExpress} from 'apollo-server-express';
import {GraphQLFactory, GraphQLModule} from '@nestjs/graphql';
import {SnippetResolvers} from "./snippet/snippet.resolvers";
import {SnippetModule} from "../snippet/snippet.module";
@Module({
imports: [
GraphQLModule,
SnippetModule
],
components: [
SnippetResolvers
]
})
export class GQLModule implements NestModule {
constructor(private readonly graphQLFactory: GraphQLFactory) {}
configure(consumer: MiddlewaresConsumer) {
const typeDefs = this.graphQLFactory.mergeTypesByPaths('./**/*.graphql');
const schema = this.graphQLFactory.createSchema({ typeDefs });
consumer
.apply(graphiqlExpress({ endpointURL: '/graphql' }))
.forRoutes({ path: '/graphiql', method: RequestMethod.GET })
.apply(graphqlExpress(req => ({ schema, rootValue: req })))
.forRoutes({ path: '/graphql', method: RequestMethod.ALL });
}
}
With the following request:
POST /graphql HTTP/1.1
Host: localhost:3000
Content-Type: application/graphql
Cache-Control: no-cache
{ snippets {name}}
I get the following response:
HTTP 500
POST body missing. Did you forget use body-parser middleware?
I found the solution reading some Apollo documentation; all I had to do was to add the following middlewares to my endpoint:
import {Module, NestModule, MiddlewaresConsumer, RequestMethod} from '@nestjs/common';
import {graphqlExpress, graphiqlExpress} from 'apollo-server-express';
import {GraphQLFactory, GraphQLModule} from '@nestjs/graphql';
import {SnippetResolvers} from "./snippet/snippet.resolvers";
import {SnippetModule} from "../snippet/snippet.module";
import * as bodyParser from 'body-parser';
@Module({
imports: [
GraphQLModule,
SnippetModule
],
components: [
SnippetResolvers
]
})
export class GQLModule implements NestModule {
constructor(private readonly graphQLFactory: GraphQLFactory) {}
configure(consumer: MiddlewaresConsumer) {
const typeDefs = this.graphQLFactory.mergeTypesByPaths('./**/*.graphql');
const schema = this.graphQLFactory.createSchema({ typeDefs });
consumer
.apply(bodyParser.text({ type: 'application/graphql' }))
.forRoutes({ path: '/graphql', method: RequestMethod.ALL })
.apply((req, res, next) => {
if (req.is('application/graphql')) {
req.body = { query: req.body };
}
next();
})
.forRoutes({ path: '/graphql', method: RequestMethod.ALL })
.apply(graphiqlExpress({ endpointURL: '/graphql' }))
.forRoutes({ path: '/graphiql', method: RequestMethod.GET })
.apply(graphqlExpress(req => ({ schema, rootValue: req })))
.forRoutes({ path: '/graphql', method: RequestMethod.ALL });
}
}
At this point, everything looks like working fine for me and I'm pretty happy with this solution. Could any of you give me some impression on this implementation? Is it the way to go? (if yes, then we should maybe add those details to the documentation)
Thanks for your time 😄
My AppModule have this configuration https://docs.nestjs.com/graphql/quick-start, but a need to upload a file with multipart/form-data, i added a new Module with a Controller with this method:
@Post('upload') @UseInterceptors(FileInterceptor('file', { storage })) async uploadFile(@UploadedFile() file, @Response() res) { return {}; }
this method never respond to a client

Current behavior
I can't access the request within my guards anymore. The request within the execution context is always undefined. It looks like the request doesn't get passed through apollo server correctly.
Expected behavior
The request should be accessible within guards.
Minimal reproduction of the problem with instructions
https://github.com/w0wka91/nest/tree/graphql-passport-integration
What is the motivation / use case for changing the behavior?
The request should be accessible to authenticate the user. Furthermore this behavior doesn't let me integrate nestjs/passport into my application.

On the documentation of Graphql there is nothing talking about Batching or Caching
https://www.npmjs.com/package/dataloader
Is there any example integrating this or get a same behavior with nestjs?
Anyway to limit the GraphQLFactory to get resolvers from current module and its imported modules?
I want to have 2 graphql endpoints. 1 protected and 1 public.
Thanks!
Playing with the graphql sample provided in the samples of nestjs, I was looking for a way to fetch the context in the resolver in order to extract user token in the header of the request to forward it to other backend services.
Unfortunately, it does not seem to be given as parameter despite its presence in the method signature -> findByOneId.
Here follows the context added to each request and expected in the resolver method call (object ->req.headers)...
configure(consumer: MiddlewareConsumer) {
const schema = this.createSchema();
this.subscriptionsService.createSubscriptionServer(schema);
consumer
.apply(
graphiqlExpress({
endpointURL: '/graphql',
subscriptionsEndpoint: `ws://localhost:3001/subscriptions`,
}),
)
.forRoutes('/graphiql')
.apply(graphqlExpress(req => ({ schema, rootValue: req, context: req.headers })))
.forRoutes('/graphql');
}
@Query('cat')
async findOneById(obj, args, context, info): Promise<Cat> {
const { id } = args;
return await this.catsService.findOneById(+id);
}
All parameters are undefined except the args one which contains the id.
Moreover, I figured out other unexpected behaviors when adding decorators to the method:
@Query('cat')
async findOneById(@Req() req, obj, args, context, info): Promise<Cat> {
const { id } = args;
return await this.catsService.findOneById(+id);
}
Here all arguments are undefined except the args one which contains... the context !! (same issue when replacing the @Req()
with @Body()
)
@Query('cat')
async findOneById(@Body() body, @Req() req, obj, args, context, info): Promise<Cat> {
const { id } = args;
return await this.catsService.findOneById(+id);
}
2 decorators allows here to fetch the whole GraphQLOptions
in the args parameter (other param still undefined). Same behavior for the signature async findOneById(args): Promise<Cat>
.

Here is a good example on how to apply Auth in GraphQL using Directive Resolvers as "resolvers middlewares" -> https://blog.graph.cool/graphql-directive-permissions-authorization-made-easy-54c076b5368e. Currently this module don't support to define directives, even that graphql-tools
allows it.
I don't know how that is handled in combination with Guards/Interceptors of Nest. Using this kind of directives allow the Schema definition to be discovered by the users and depending the role to show or hide specific fields.
I found an issue regarding guards. Let's take the following example:
import { Injectable, CanActivate, ExecutionContext } from '@nestjs/common';
import { Observable } from 'rxjs';
import { Reflector } from '@nestjs/core';
@Injectable()
export class RolesGuard implements CanActivate {
constructor(private readonly reflector: Reflector) {}
canActivate(context: ExecutionContext): boolean {
const roles = this.reflector.get<string[]>('roles', context.getHandler());
if (!roles) {
return true;
}
const request = context.switchToHttp().getRequest();
const user = request.user;
return user && user.role && roles.some((role) => role === user.role));
}
}
Now, in the rest of the framework this works like a charm. But whenever you are in graphql, this doesn't work quite as well. Taking the following .gql
file.
type Bookings implements Node {
id: ID!
...
}
type BookingEdge {
cursor: ID!
node: Booking
}
type BookingConnection {
edges: [BookingEdge]
nodes: [Booking]
pageInfo: PageInfo!
totalCount: Int!
}
type Restaurant implements Node {
id: ID!
orders(first: Int, after: String, last: Int, before: String):OrderConnection
...
}
type Query {
restaurant(id: ID!): Restaurant
}
For the following query, the const request = context.switchToHttp().getRequest();
becomes the user.
query ($id: ID!) {
restaurant(id: $id) {
id
bookings {
nodes {
id
}
}
}
}
So, in this query, request.user
in the guard, becomes undefined
and you have to make a workaround:
canActivate(context: ExecutionContext): boolean | Promise<boolean> {
const roles = this.reflector.get<string[]>('roles', context.getHandler());
const request = context.switchToHttp().getRequest(); //this works only for when querying a parent type
const ctx = context.getArgByIndex(2); // this works for when querying a child.
const user = request.user || ctx.user;
return user && user.role && roles.some((role) => role === user.role));
}
Can you guys check if it happens to you or it's an issue of mine? Thank you.
Does this package support Apollo Server 2.0 or the older version? I installed their release candidate for express (apollo-server-express@rc). graphqlExpress is no longer available. import { graphqlExpress } from 'apollo-server-express';
How would I go about using nestjs/graphql with Apollo Server 2.0?
thank you
Hi!
I just discovered this framework and I have to say it’s awesome. Kudos!
The GraphQL module is great, but I did not find any information regarding how to do batching and caching, which is pretty required to avoid a big waste of resources (see https://github.com/facebook/dataloader).
Given the fact that resolvers are automatically mapped, I guess there’s currently no way to do that, right? An integration with dataloader would be awesome, if not mandatory for any medium to large application.
And, happy new year, by the way. ☺️
Very excited about NestJS. Thinking of becoming a sponsor if it proves out for my new project.
I need to get GraphQL subscriptions working. For starters, I've implemented the example from docs, and now I'm trying to connect GraphiQL with something like this:
consumer
.apply(graphiqlExpress({
endpointURL: "/graphql",
subscriptionsEndpoint: `ws://localhost:${process.env.PORT || 3000}/subscriptions`
}))
.forRoutes({path: "/graphiql", method: RequestMethod.GET})
.apply(graphqlExpress(req => ({schema, rootValue: req})))
.forRoutes({path: "/graphql", method: RequestMethod.ALL});
I'm getting ERR_CONNECTION_REFUSED
in browser console. I feel like I'm missing the connection between GraphQL Subscriptions and WebSockets, but I can't seem to piece it together from the docs.
Are there any working e2e examples out there?
Hi, I am new to NestJS, so I hope this issue is not my mistake. I think NestJS's GraphQL module does not support resolvers that returns observables. This is kind of unexpected as the REST counterpart (i.e. controllers) supports observables.
With heyPromise
, I am able to get 'from promise'. However, heyObservable
returns this instead:
{
"data": {
"heyObservable": "[object Object]"
}
}
The expected data for heyObservable
should be 'from rxjs'. For now, we will need to workaround by turning the observable into a promise (i.e. heyObservable_workaround_is_ok
)
Snippet of schema & resolvers used:
type Query {
heyPromise: String
heyObservable: String
}
@Query()
async heyPromise () {
return new Promise(resolve => resolve('from promise'))
}
@Query()
heyObservable () {
return of('from rxjs')
}
@Query()
heyObservable_workaround_is_ok () {
return of('from rxjs').toPromise()
}
This syntax is not working in the NPM version. Probably a release is pending.
const resolvers = {
UUID: GraphQLUUID
}
const typeDefs = this.graphQLFactory.mergeTypesByPaths('./**/*.graphql');
const schema = this.graphQLFactory.createSchema({ typeDefs, resolvers });
Hello,
Is there any good way to validate data in mutations like string length etc?
typescript mutation { createSth(name:"something", website:"http://test.com/") { id name website } }
How can i validate name or website data?
PS: Kamil, great job with nestjs!

Trying to configure GraphQL subscriptions using existing express server.

Following code
const typeDefs = this.graphQLFactory.mergeTypesByPaths(
`src/@core/**/*.graphqls`,
`src/${process.env.APP_NAME}/**/*.graphqls`
);
will only generate type definitions for first pattern: src/@core/**/*.graphqls
, all next patterns not merged.
Manual merging fixes this issue:
import { fileLoader, mergeTypes } from 'merge-graphql-schemas';
const coreTypes = fileLoader(`src/@core/**/*.graphqls`);
const appTypes = fileLoader(`src/${process.env.APP_NAME}/**/*.graphqls`);
const types = coreTypes.concat(appTypes);
const typeDefs = mergeTypes(types);
Ho can the query method be passed to the right Query type parent?
Or how can the resolver class be annotated correctly in order to resolve?
.graphql
type CustomQuery{
foo: String
}
type Query {
mw: CustomQuery
}
CustomResolver
import { Query, Resolver } from '@nestjs/graphql';
@Resolver()
export class CustomResolver {

Passing a string representation of the schema on the other hand works, but then I need to cast the string to any
to avoid type errors.
This line in the GraphQLFactory
class seems to be the point that the value is used as a string (or array of strings to be exact):
|
typeDefs: gql` |
|
${options.typeDefs} |
|
`, |
Expected behavior
Either the GraphQLFactory should perform a check to see if the typeDefs
is a DocumentNode, and if so then skip the gql
tag call.
Or just change the GqlModuleOptions
to make typeDefs a string type.
Environment
Nest version: 5.3.0, graphql v5.1.0

I followed the instruction to create a nestjs app successfully. I am now trying to add graphql to the server using the instructions provided here https://docs.nestjs.com/graphql/quick-start. After installing the requrired packages via yarn
and adding the GraphQLModule
with empty schema, i run yarn start
and I get the following error:
yarn run v1.7.0
$ ts-node -r tsconfig-paths/register src/main.ts

Current behavior
I want to implement two endpoints. For this goal I have two modules: AdminModule and SiteModule. In each module I imported GraphQLModule:
GraphQLModule.forRootAsync({
useFactory: async () => {
return {
typePaths: ['./src/admin/**/*.graphql'],
path: '/admin',
}
},
})
and
GraphQLModule.forRootAsync({
useFactory: async () => {
return {
typePaths: ['./src/site/**/*.graphql'],
path: '/site',
}
},
})
In this case only /admin
is available. When I request /site
it returns 404. From another side I can use forRoot
instead of forFootAsync
. In this case both endpoints work as expected. But I have to use forRootAsync
for have possibility to define allowResolversNotInSchema: true
by the issue described in #19. Without It I get error: Error: "Mutation" defined in resolvers, but not in schema
when in shared module I add some resolver which defined only in one of two schemes.
Expected behavior
Possibility for implement multiple endpoints
Minimal reproduction of the problem with instructions
- Use with example https://github.com/nestjs/nest/tree/master/sample/12-graphql-apollo/src
- Add two modules with configs as described above.
What is the motivation / use case for changing the behavior?
It is very convenient for have possibility for split public and protected API.
Environment
Nest version: 5.3.0
For Tooling issues:
- Node version: 10.1.0
- Platform: Windows
With @nestjs/graphql, how to generate document for graphql api ?

There is No Description.
Since apollo-server-express
is not working in the Nest way, a new middleware, that adapts to the Exception handling of Nest should be created. The original issue was created in @nestjs/nest
since the example in the documentation leads to use this library.
Related issue nestjs/nest#556
I have seen those similar issues nestjs/nest#484, nestjs/nest#488 and they seem to be resolved. However, I am on @nestjs/graphql v3.0.0, @nestjs/common and /core v5.0.0 and the following code:
@Module({
imports: [GraphQLModule]
})
export class GraphQLSetupModule {
private readonly schema: any;
constructor(graphQLFactory: GraphQLFactory) {
this.schema = graphQLFactory.createSchema({
typeDefs: mergedTypes
});
}
}
where mergedTypes
is exactly:
schema {
query: Query
}
type Query {
countries: [Country]
}
directive @entity on OBJECT
type Country @entity {
# The id is also the official ISO code of the country.
_id: ID
name: String
}
fails with stack trace:

Current behavior
I cant't figure out how set custom header during a query request.
Header decorator, doesn't work, nor Response decorator.
Let me know if there is another way.
Expected behavior
There should be the ability to use header decorator as for the controller:
@Header('x-custom-header', 'xxxx')
@query('books')
async getBooks() {
....
}

Environment
Nest version: X.Y.Z
For Tooling issues:
- Node version: XX
- Platform:
Others:
I have the following code snippet that works fine in graphql-yoga.
Subscription: {
post: {
subscribe: (parent, args, ctx, info) => {
return ctx.db.subscription.post(
{
where: {
mutation_in: ["CREATED", "UPDATED"]
}
},
info
);
}
}
},
If I try to get the context in the Nest way - all of those args are undefined
@Subscription('post')
onPostMutation(parent, args, ctx, info) {
// all args are undefined
// ...
}
So my question - how to get context and args for a subscription?
Is there any way to add @Body to this library for the args param. Finding it frustrating having to convert POJO's from inputs to TypeScript classes.
Hey, I want know a possibility to send an array of errors using the GraphQL module.
Is it possible with GraphQL module using a mutation? I have no idea how to implement it.
Big thanks.
