Using buildSchema multiple times for different resolver paths on same server

[tugaykaracay]

Hi I would like host multiple graphql endpoints on same express server on different paths but when I use buildSchema for second time it also contains previously loaded schema's types/queries/mutations. Is there any way to clear previously loaded schema cache before loading next one?

This is my load schema function:

import { buildFederatedSchema as buildApolloFederationSchema, printSchema } from '@apollo/federation';
import { GraphQLSchema } from 'graphql';
import gql from 'graphql-tag';
import { buildSchemaSync, createResolversMap, GraphQLTimestamp } from 'type-graphql';
import { authChecker } from '../permissions';

type BuildFederatedSchemaParams = {
  resolverPath: string;
  emitSchemaFile?: string | undefined;
}

export function buildFederatedSchema({
  resolverPath,
  pubSub,
  emitSchemaFile,
}: BuildFederatedSchemaParams): GraphQLSchema {
  const schema = buildSchemaSync({
    resolvers: [resolverPath],
    orphanedTypes: [],
    authChecker,
    emitSchemaFile,
    dateScalarMode: 'timestamp',
  });

  return buildApolloFederationSchema({
    typeDefs: gql(printSchema(schema)),
    resolvers: createResolversMap(schema) as any,
  });
}

You need to provide the resolvers array manually. Using resolversPath is not supported for multiple schemas mode.
