How do I set up Sequelize with Node.js?

To set up Sequelize with Node.js, first install Sequelize and the database driver using npm. For example, for PostgreSQL, run npm install sequelize pg pg-hstore.

What configuration do I need to do after installation?

After installation, you need to create a Sequelize instance by providing database credentials. Here's a basic example:

const { Sequelize } = require('sequelize');
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'postgres',
});

How do I define a model in Sequelize?

You can define a model by extending the Sequelize Model class. Here's an example:

const { Model, DataTypes } = require('sequelize');

class User extends Model {}
User.init({
  username: DataTypes.STRING,
  password: DataTypes.STRING,
}, { sequelize, modelName: 'user' });

Can you show me how to sync the model with the database?

Sure! You can sync the model with the database using the sync method:

sequelize.sync().then(() => {
  console.log('User model synced with the database!');
});
