How do I set up TypeORM in a Node.js project?

To set up TypeORM in your Node.js project, first install it using npm: npm install typeorm reflect-metadata. You also need a database driver, like pg for PostgreSQL.

What configuration do I need for TypeORM?

You need to create a ormconfig.json file or configure it in your code. It should include details like type, host, port, username, password, and database name.

Can you show me a sample configuration?

Sure! Here's a sample ormconfig.json:

{
  "type": "postgres",
  "host": "localhost",
  "port": 5432,
  "username": "your_username",
  "password": "your_password",
  "database": "your_database",
  "synchronize": true,
  "entities": ["src/entity/**/*.ts"]
}

How do I create an entity in TypeORM?

You can create an entity by defining a class and using decorators. For example:

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

@Entity()
export class User {
  @PrimaryGeneratedColumn()
  id: number;

  @Column()
  name: string;
}
