How to set mongoose plugin to a schema after creating NestFactory

Question

I'm using nest, I need to call another service to get a key before setting a mongoose plugin, I tried to init the mongoose plugin in main.ts, but it doesn't work, below is what I did

test.schema.ts

  import { Document } from 'mongoose';
            
    export class TestSchema extends Document{
           readonly test: String;
    }

init.schema.ts

    export const initMongoosePlugin = () => {
    
      TestSchema.plugin(plugin, {
        fields: ['test'],
        secret: global['KEY'], // init it in main.ts
      });
    
    };

main.ts

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  const appService: AppService = app.get(AppService);
  global['KEY'] = await appService.getKey();
  // init Mongoose Plugin
  initMongoosePlugin();
  app.use(requestIp.mw());
  await app.listen(3000));
}
bootstrap();

then when main.ts runs, the MongooseModule has been initialized with all of its models (forFeature), you can use app.get to grab the Model you need then get the schema out of the model then set the plugin on the schema — Chau Tran, Oct 07 '19 at 02:10

Do you get error or it is just not set? Have you tried to call it from the service constructor in which you inject the schema? However I use the following to define a schema in mongodb

import { Schema } from 'mongoose';

export const TestSchema = new Schema(
    {
      test: String;
    }
);
