Join query in MongoDb and Nodejs

Date: 2022-03-16

This tutorial demonstrates how to perform join queries in MongoDB using Node.js and the $lookup aggregation operator. It uses Docker for MongoDB setup and walks through creating a Node.js application that connects to MongoDB, populates sample collections (orders and products), and then uses $lookup to perform a left outer join between them. The tutorial covers setting up Node.js, Docker, and MongoDB, as well as creating the necessary files (package.json, model.js, main.js) to execute the join query. The result is printed to the console.
