Failed to load schema from ./server/graphql/schema.graphql

[deadcoder0904]

I am unable to create schema.graphql file when using prisma + nexus-prisma & thus unable to generate GraphQL Codegen (i tried this on my working setup that deleting schema.graphql throws the same error)

It throws the following error:

Failed to load schema from ./server/graphql/schema.graphql:

My codegen.yml looks like:

schema: ./server/graphql/schema.graphql
documents:
  - '**/*.graphql'
  - '!/server/graphql/schema.graphql'
generates:
  /client/graphql/types.generated.ts:
    plugins:
      - typescript
  ./:
    preset: near-operation-file
    presetConfig:
      baseTypesPath: /client/graphql/types.generated.ts
    plugins:
      - typescript-operations
      - typescript-urql

And my server/graphql/schema.ts looks like:

import { makeSchema } from 'nexus'
import path from 'path'

import User from './User'

const shouldGenerateArtifacts =
  process.env.NODE_ENV === 'development' || !!process.env.GENERATE

export const schema = makeSchema({
  types: [User],
  plugins: [],
  // Type the GraphQL context when used in Nexus resolvers
  contextType: {
    module: path.join(process.cwd(), 'pages/api/index.ts'),
    export: 'GraphQLContext',
  },
  // Generate the files
  shouldGenerateArtifacts,
  outputs: {
    typegen: path.join(
      process.cwd(),
      'server/graphql/nexus-types.generated.ts'
    ),
    schema: path.join(process.cwd(), 'server/graphql/schema.graphql'),
  },
})

How do I make sure it creates server/graphql/schema.graphql before graphql-codegen runs?

Repro is available on prisma branch on this commit → deadcoder0904/twitter-api-v2-3-legged-login-using-next-connect@60d7924

I actually have the same question, though I think my solution is simply going to be to upload the generated graphql schema file to my github repo and refer to it statically there. By the way I'm using typegraphql to generate the file when running my server in development mode

[deadcoder0904]

@ardatan you know any examples that do that? would be incredibly helpful as i'm using codegen for the 1st time :)

[ardatan]

Just point to server/graphql/schema.ts, and add ts-node/register under require.

require: ts-node/register/transpile-only
schema: ./server/graphql/schema.ts

@ardatan i did what you said & it gave me:

Failed to load schema from ./server/graphql/schema.ts: Cannot use import outside module

then it somehow worked after undoing what you said. it works sometimes & sometimes it doesn't. weird :(

if someone could create a sample project we could jump in and help.
Also later it would be great if that someone could add that to the docs
Thanks!

@Urigo just created a sample project → https://github.com/deadcoder0904/codegen-error

install deps & try running npm run dev which should run the predev script & it should show:
