Create a Microservice using SQLite and MongoDB in Node.js

Microservices in Node.js is like running a virtual reality theme park. With SQL and NoSQL as the main attractions, it’s a wild ride of data management. But remember, it’s a no-holds-barred thrill ride, so don’t expect Fort Knox-level security. Just buckle up and enjoy the code carnival! 🎢🎡🎠

Introduction

Microservices in Node.js are a powerful way to create scalable, modular applications. In this article, we will explore how to create two services – one with a SQL database and the other with a NoSQL database. We will use SQLite and MongoDB to demonstrate the implementation of microservices in Node.js.

Key Takeaways

Here is a quick overview of what we will cover in this article:

User Service with MongoDB 🚀

We will start by creating a user service using MongoDB. In this service, we will handle user authentication and data manipulation.

Initializing the Application

First, we need to initialize our Node application and install the required dependencies using the following commands:

npm install express mongoose

After installing the dependencies, we create the app.js as the root application for our user service.

Product Service with SQLite 📦

Next, we will create a product service using SQLite to manage products in our application.

Setting up the Database

To begin, we initialize our Express application and SQLite database to handle data storage and manipulation.

npm init -y
npm install express sqlite3

Once the database is set up, we can create the necessary tables for storing product information.

Conclusion

In this article, we explored the implementation of microservices in Node.js using SQLite and MongoDB. We demonstrated how to create user and product services with different databases for handling data and authentication.
