Node.js CRUD App

Building a CRUD App

Node.js CRUD app with MongoDB handles create read update delete.

Introduction to CRUD Operations

CRUD stands for Create, Read, Update, and Delete. These are the four basic operations for managing data in an application. In this tutorial, we will build a simple Node.js application that performs these operations using MongoDB as the database.

Setting Up the Environment

Before starting, ensure you have Node.js and MongoDB installed on your machine. We will use Express for the server framework and Mongoose for MongoDB interaction.

Installing Required Packages

Initialize your project and install the necessary packages using npm:

Connecting to MongoDB

Set up a connection to your MongoDB database using Mongoose. Create a file named db.js and add the following code:

Defining the Data Model

Create a model.js file to define the data model. Here, we will create a simple model for a user with a name and email:

Implementing CRUD Operations

Now, let's implement the CRUD operations in a server.js file:

Conclusion

In this guide, we've set up a basic Node.js application that can perform CRUD operations using MongoDB. This serves as a foundation for building more complex applications. Explore adding more features such as authentication and validation to enhance functionality.
