Usage

Import the DrizzleTursoModule module and pass an options object to initialize it. You can pass options object using the usual methods for custom providers as shown below:

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import * as schema from '../db/schema';
import { DrizzleTursoModule } from '@knaadh/nestjs-drizzle-turso';

@Module({
  imports: [
    // Method #1: Pass options object
    DrizzleTursoModule.register({
      tag: 'DB_DEV',
      turso: {
        config: {
          url: 'DATABASE_URL',
          authToken: 'DATABASE_AUTH_TOKEN',
        },
      },
      config: { schema: { ...schema } },
    }),

    // Method #2: useFactory()
    DrizzleTursoModule.registerAsync({
      tag: 'DB_PROD',
      useFactory() {
        return {
          turso: {
            config: {
              url: 'DATABASE_URL',
              authToken: 'DATABASE_AUTH_TOKEN',
            },
          },
          config: { schema: { ...schema } },
        };
      },
    }),

    // Method #3: useClass()
   DrizzleTursoModule.registerAsync({
      tag: 'DB_STAGING',
      useClass: DBConfigService,
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}

export class DBConfigService {
  create = () => {
    return {
      turso: {
        config: {
          url: 'DATABASE_URL',
          authToken: 'DATABASE_AUTH_TOKEN',
        },
      },
      config: { schema: { ...schema } },
    };
  };
}

You can inject the Drizzle instances using their respective tag specified in the configurations

import { Inject, Injectable } from '@nestjs/common';
import * as schema from '../db/schema';
import { LibSQLDatabase } from 'drizzle-orm/libsql';
@Injectable()
export class AppService {
  constructor(
    @Inject('DB_DEV') private drizzleDev: LibSQLDatabase<typeof schema>,
    @Inject('DB_PROD') private drizzleProd: LibSQLDatabase<typeof schema>
  ) {}
  async getData() {
    const books = await this.drizzleDev.query.books.findMany();
    const authors = await this.drizzleProd.query.authors.findMany();
    return {
      books: books,
      authors: authors,
    };
  }
}

Configuration

A DrizzleTursoModule option object has the following interface:

export interface DrizzleTursoConfig {
  turso: {
    config: Config;
  };
  config?: DrizzleConfig<any> | undefined;
}

• turso.config: Turso config
• (optional) config: DrizzleORM configuration.
