How do I handle relations in Node.js using an ORM?

You can handle relations in Node.js using ORMs like Sequelize or TypeORM. What specific relation are you trying to implement?

I want to set up a one-to-many relationship between users and posts.

In Sequelize, you can define a one-to-many relationship like this: User.hasMany(Post) and Post.belongsTo(User). Would you like a code example?

Yes, please provide a code example.

Sure! Here’s a simple example:

const User = sequelize.define('User', { /* attributes */ });
const Post = sequelize.define('Post', { /* attributes */ });

User.hasMany(Post);
Post.belongsTo(User);

This sets up the relationship. Do you need help with anything else?
