Import typescript file in schema: Syntax Error: Cannot parse the unexpected character "."

[devautor]

How do I import a typescript file as the schema in graphqlgen configuration.

I am using graphql-code-generator to generate types from my schema using:
schema: http://localhost:4000/graphql
Then, as I am trying to use graphqlgen to generate resolvers from these generated types and the schema.

I am getting this error:

G:\server\prod\apollo-server>graphqlgen
Error occurred while reading schema: Syntax Error: Cannot parse the unexpected character ".".

GraphQL request (1:1)
1: ./src/makeExecutableSchema.ts
   ^


G:\server\prod\apollo-server>

My graphqlgen.yml is:

# The target programming language for the generated code
language: typescript

# The file path pointing to your GraphQL schema
schema: ./src/makeExecutableSchema.ts

# Type definition for the resolver context object
context: ./src/context.ts:Context

# Map SDL types from the GraphQL schema to TS models
models:
  files:
    #- ./src/generated/prisma-client-ts/index.ts
    - ./src/types.d.ts

# Generated typings for resolvers and default resolver implementations
# Please don't edit this file but just import from here
output: ./src/generated/graphqlgen.ts

# Temporary scaffolded resolvers to copy and paste in your application
resolver-scaffolding:
  output: ./src/generated/tmp-resolvers/
  layout: file-per-type

Can you share the contents of ./src/makeExecutableSchema.ts?

Hello @jasonkuhrt Sure, here is my ./src/makeExecutableSchema.ts:

/**
 * Makes executable schema for Apollo server API
 * from typedefs and resolvers, and adds permissions middleware
 */

import { makeExecutableSchema } from "apollo-server";
import typeDefs from "./schema";
//import { resolvers } from "./resolvers";
// import all scalar resolvers
import OKGGraphQLScalars from "@okgrow/graphql-scalars";

import { applyMiddleware } from "graphql-middleware";
//import permissions from "./auth/permissions";

const schema = makeExecutableSchema({
  typeDefs: typeDefs,
  resolvers: {
    ...OKGGraphQLScalars
  }
});

// with auth permission middleware, using graphql-shield
export default () => {
  // console.log(`Applying permissions middleware...`);
  // return applyMiddleware(schema, permissions);
  return applyMiddleware(schema);
};

And, here is my ./src/schema.ts:

// Graphql schema of the server API

import { gql } from "apollo-server";
// import all scalars
import { OKGScalarDefinitions } from "@okgrow/graphql-scalars";

// importing typescript files, each is gql`...` extending types Query, Mutation, Subscription
import sharedSchema from "./schema/shared";  
import postSchema from "./schema/post";
import storeSchema from "./schema/store";
import customerSchema from "./schema/customer";
import collectionSchema from "./schema/collection";
import productVariantSchema from "./schema/productVariant";

const blankSchema = gql`
  type Query {
    _blank: String
  }

  type Mutation {
    _blank: String
  }

  type Subscription {
    _blank: String
  }
`;

const schema = [
  blankSchema,
  ...OKGScalarDefinitions,
  sharedSchema,
  postSchema,
  storeSchema,
  customerSchema,
  collectionSchema,
  productVariantSchema
];

export default schema;

schema: ./src/makeExecutableSchema.ts

Should be

schema: ./src/schema.ts

Thanks for the reply @jasonkuhrt but that too gives the same error.

Error occurred while reading schema: Syntax Error: Cannot parse the unexpected character ".".

@devautor thanks for confirming, it is a step in the right direction.

Are you using at least 0.6.0-rc4. Only starting from that version was it possible to import from TypeScript files.

[devautor]

Thanks @jasonkuhrt for your patience! Yes, I am using "graphqlgen": "^0.6.0-rc4" (copied from package.json).

[jasonkuhrt]

@devautor same to you :) I'll try to take a closer look at this tonight or failing that in the coming days.

[devautor]

Oh, sure! I hope you could find time for this tonight, or sooner than later (I have my timeline set to "Write resolvers" from today tomorrow). [I understand that you must have n things to do :) ]

[jasonkuhrt]

Hey @maticzav on your end are you experiencing any issues having graphqlgen get schema from your TS module?

[devautor]

Hi @jasonkuhrt Thank you so much for your fix; but I am not able to get it running still, am I doing something wrong here:

I only just published the new version. Give 0.6.0-rc6 a try.
