How to setup mongoDB using typeorm on nestjs

default.module.ts

import { Module, NestModule } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';

@Module({
  imports: [
    TypeOrmModule.forRoot({
      ...{
        type: 'mongodb',
        url: '<your-mongo-db-atlas-url-here>',
        synchronize: false,
        logging: false,
        entities: [__dirname + '../../teste/entities/*.entity{.ts,.js}'], // Insert the path for your entities
      },
      name: 'mongo', // name the connection to handle multiple databases
    }),
  ],
  providers: [],
})
export class DefaultModule implements NestModule {}

test.controller.ts

import { Controller, Get } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { MongoRepository } from 'typeorm';

import { TestEntity } from './entities/test.entity';

@Controller('test')
export class TestController {
  constructor(
    @InjectRepository(TestEntity, 'mongo')
    private readonly repository: MongoRepository<TestEntity>,
  ) {}

  // This method is performing an atlas search (https://www.mongodb.com/atlas/search) as an example
  @Get()
  public testMethod() {
     return this.repository.aggregate([
      {
        $search: {
          index: 'default',
          text: {
            query: 'per inf',
            path: {
              wildcard: '*',
            },
          },
        },
      },
    ]).toArray()
  }
}

test.entity.ts

import { Column, Entity, ObjectID, ObjectIdColumn } from 'typeorm';

@Entity('test')
export class TestEntity {
  @ObjectIdColumn()
  id: ObjectID;

  @Column()
  searchWord: string;

  @Column()
  algorithmId: number;
}

test.module.ts

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';

import { TestEntity } from './entities/test.entity';
import { TestController } from './test.controller';

@Module({
  imports: [TypeOrmModule.forFeature([TestEntity], 'mongo')],
  controllers: [TestController],
})
export class TestModule {}
