TypeORM

The best library to connect NestJS with MariaDB is TypeORM. TypeORM is an object-relational mapper (ORM) that provides a simple and effective way to interact with databases. It supports a wide range of databases, including MariaDB, MySQL, PostgreSQL, and SQLite.

To connect NestJS with MariaDB using TypeORM, you need to:

1. Install the TypeORM package:

npm install typeorm mariadb

1. Create a TypeORM configuration file:

// ormconfig.json
{
  "type": "mariadb",
  "host": "localhost",
  "port": 3306,
  "username": "root",
  "password": "",
  "database": "my_database"
}

1. Import the TypeOrmModule into your NestJS root module:

// app.module.ts
import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';

@Module({
  imports: [
    TypeOrmModule.forRoot()
  ],
})
export class AppModule {}

1. Create a repository for each of your MariaDB entities:

// user.repository.ts
import { EntityRepository, Repository } from 'typeorm';
import { User } from './user.entity';

@EntityRepository(User)
export class UserRepository extends Repository<User> {}

1. Inject the repository into your controllers and services:

// user.controller.ts
import { Controller, Get } from '@nestjs/common';
import { UserRepository } from './user.repository';

@Controller('users')
export class UserController {
  constructor(private readonly userRepository: UserRepository) {}

  @Get()
  async getAllUsers() {
    return await this.userRepository.find();
  }
}

Once you have followed these steps, you will be able to connect NestJS to MariaDB and start interacting with your database.

Here are some additional tips for connecting NestJS with MariaDB using TypeORM:

• You can use the TypeORM CLI to generate migrations and entities for your database.

• You can use the TypeORM documentation to learn more about how to use TypeORM with NestJS.

• There are a number of tutorials and examples available online for using TypeORM with NestJS.

Best Practice

Professionals typically develop Svelte and NestJS applications in separate projects. This allows them to scale the applications independently and use different development tools and workflows for each application.

Here are some of the benefits of developing Svelte and NestJS applications in separate projects:

• Scalability: It is easier to scale Svelte and NestJS applications independently. This is because each application can be deployed on its own server and scaled according to its needs. For example, if the Svelte application is receiving a lot of traffic, it can be scaled up by adding more servers.

• Development tools and workflows: Different development tools and workflows can be used for each application. For example, developers may use a different code editor and IDE for Svelte development than for NestJS development.

• Code reuse: Code can be reused between the two applications. For example, the Svelte application can use the same authentication service as the NestJS application.

However, there are also some challenges associated with developing Svelte and NestJS applications in separate projects:

• Complexity: It can be more complex to set up and configure Svelte and NestJS applications in separate projects. This is because the two applications need to be able to communicate with each other.

• Code sharing: It can be more difficult to share code between Svelte and NestJS applications. This is because the two applications are using different programming languages and frameworks.

Overall, the best way to develop Svelte and NestJS applications depends on your specific needs and requirements. If you need to be able to scale your applications independently and use different development tools and workflows, then developing them in separate projects is a good option. However, if you need to be able to easily share code between the two applications, then developing them in the same project may be a better option.

Here are some examples of how professionals are developing Svelte and NestJS applications in separate projects:

• NestJS API and Svelte frontend: This is a common architecture for developing web applications. The NestJS API provides the backend functionality, such as authentication, authorization, and data access. The Svelte frontend provides the user interface.

• NestJS microservices and Svelte frontend: This architecture can be used to develop more complex web applications. The NestJS microservices provide different functionalities, such as a user service, a product service, and an order service. The Svelte frontend communicates with the NestJS microservices to get the data it needs to render the user interface.

• NestJS backend and SvelteKit frontend: This architecture can be used to develop single-page applications (SPAs). The NestJS backend provides the backend functionality, such as authentication, authorization, and data access. The SvelteKit front end provides the user interface and routing.
