What are some examples of using micro ORM in my project?

Micro ORM (Object-Relational Mapping) libraries are lightweight tools that help you interact with databases. For example, in a Node.js project, you could use TypeORM or Sequelize as a micro ORM to manage your database operations with minimal overhead.

Can you show me a simple code example using TypeORM?

Sure! Here's a basic example:

import { Entity, PrimaryGeneratedColumn, Column, createConnection } from 'typeorm';

@Entity()
class User {
    @PrimaryGeneratedColumn()
    id;

    @Column()
    name;

    @Column()
    age;
}

createConnection({
    type: 'sqlite',
    database: 'test.db',
    entities: [User],
    synchronize: true,
}).then(async connection => {
    const user = new User();
    user.name = 'John Doe';
    user.age = 30;
    await connection.manager.save(user);
    console.log('User has been saved!');
});

This code defines a User entity and saves a new user to the database.

What are the advantages of using a micro ORM?

Micro ORMs are lightweight and easy to use, which makes them faster to set up compared to full-fledged ORMs. They provide a simple API for basic CRUD operations, reduce boilerplate code, and often have better performance for smaller applications.

Are there any downsides to using micro ORMs?

Yes, while micro ORMs are great for simplicity and speed, they may lack some advanced features found in larger ORMs, such as complex query building, caching, or built-in migrations. This can be a limitation for more complex applications.
