ES imports doesn't work?

[misha-erm]

Hello 👋🏻

As I can see #124 was implemented but I have some problems with it. When I try to import nexus-prisma it still tries to import cjs module so I get errors trying to run my app.

Any ideas? type is set to 'module' and nexus-prisma is imported using "import" keyword

EDIT: If I change import to

import nexusPrisma from 'nexus-prisma';

const {FuelStation} = nexusPrisma

then I get the following error:

(node:56355) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
/Volumes/Workspace/pets/cheapoil/core/node_modules/nexus-prisma/dist-esm/entrypoints/main.js:1
import { inspect } from 'util';
^^^^^^

SyntaxError: Cannot use import statement outside a module

I imagine you already solved your issue. It works fine for me using nexus-prisma@0.34.0.

If you still haven't found a solution check if the API schema gets generated when running prisma generate.
If not, chances are you haven't added the generator to your prisma.schema file like so:

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider        = "prisma-client-js"
}

generator nexusPrisma {
  provider = "nexus-prisma"
}

You should see something like this in the command output

Are you sure you use it in ESM module environment?

Because the issue isn't fixed. You can find the details here #142

I'm pretty sure I am using ESM module environment. One of my type files looks something like this

import { User } from "nexus-prisma";
import { objectType, extendType, stringArg, nonNull } from "nexus";

export const UserDef = objectType({
   name: User.$name,
   description: User.$description,
   definition(t) {
      t.field(User.id);
      t.field(User.myId);
      t.field(User.name);
      t.field(User.username);
      t.field(User.corsi);
   },
});

// Other stuff...

and i don't get the error you are reporting. I get a different one which I mention here #169 so that might be covering it but still it seems to be working for me. I get code completion and no squiggly lines around the file.

I'm definitely no expert in this so I might as well be doing something different than you and not realise it.

[misha-erm]

Do you have type: "module" in your package json?

[milovangudelj]

He he, nope... 😅
I didn't have it. And adding it breaks my application in ways I don't yet understand.

As I said, I'm no expert so I might have that issue and don't notice it cause its hidden behind other errors.

Sorry for jumping in like I had the solution 😅

P.S.
Thank you for asking me that cause it pushed me to try and get a deeper understanding of ES modules. That's why it took me so long to answer

Did you ever manage to fix this? I'm having the exact same issue as you just running the example from nexus-prisma docs website...

error:

import { User } from 'nexus-prisma';
         ^^^^
SyntaxError: Named export 'User' not found. The requested module 'nexus-prisma' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'nexus-prisma';
const { User } = pkg;

prisma generate:

I meet this issue too and have no idea.
The error is shown below:

I'd say this is a new issue as it seems to affect the ESM build in version ^1.
