import Package is not available in all CommonJS modules

[Trandx]

What's the good way to use this package in Nestjs ?

I have tried to make test, but nestjs Builder has Throw this error

Error [ERR_REQUIRE_ESM]: require() of ES Module docker_test/app/node_modules/.pnpm/@authzed+authzed-node@1.2.0/node_modules/@authzed/authzed-node/dist/src/index.js from /docker_test/app/dist/app.service.js not supported.
Instead change the require of index.js in /dev/docker_test/app/dist/app.service.js to a dynamic import() which is available in all CommonJS modules.

this is the code of app.service.ts

`
import { v1 } from '@authzed/authzed-node';
import { Injectable, Logger } from '@nestjs/common';

@Injectable()
export class AppService {

private readonly logger = new Logger(AppService.name);
private client: v1.ZedClientInterface;

constructor() {
  // Initialize AuthZed (SpiceDB) gRPC Client
  this.client = v1.NewClient(
    process.env.SPICEDB_TOKEN || 'mysecret', // Use ConfigService for env vars
    process.env.SPICEDB_HOST || 'localhost:50051', // Use ConfigService for env vars
  );
}

async checkPermission(): Promise<any> {
  try {
    // Create the resource reference
    const firstPost = v1.ObjectReference.create({
      objectType: 'blog/post',
      objectId: '1',
    });

    // Create the user reference
    const emilia = v1.ObjectReference.create({
      objectType: 'blog/user',
      objectId: 'emilia',
    });

    // Create the subject reference using the user reference
    const subject = v1.SubjectReference.create({
      object: emilia,
    });

    // Create the permission check request
    const checkPermissionRequest = v1.CheckPermissionRequest.create({
      resource: firstPost,
      permission: 'read',
      subject,
    });

    // Use await to handle the asynchronous call
    const response = this.client.checkPermission(checkPermissionRequest, ((err, resp) => {
      console.error(err)
      console.log(resp)

      return resp || err
    }));
    
   this.logger.log('Permission check response:', response);

    return response;
  } catch (error) {
    this.logger.error('Error checking permission:', error);
    throw error; // Re-throw the error to be handled by the caller
  }
}

}

A few things:

1. Have you tried naming this file with a .mjs extension instead of a .js extension? Depending on the version of Node you're using, it may force that.
2. Have you tried reversing the order of the imports? i.e. can we isolate this to an issue with imports generally vs importing the authzed-node package specifically?
3. Is nestjs doing anything to transpile the code or otherwise mess with the import system (e.g. how Jest patches the import system)?

Chatted with another user who's experiencing the same issue. It looks like NestJS is indeed the problem, and they don't currently have plans to support ESM usage, but there is a workaround with --experimental-require-module flag: nestjs/nest#13319 (comment)

Is that sufficient for your use case? We can also theoretically export a commonJS package as well.
