How to use Mongoose with Next JS 13 for MongoDB

Next.js is a popular framework for building server-side rendered React applications. It offers a great developer experience and makes it easy to build fast and scalable web applications. MongoDB is a leading NoSQL database that is commonly used with Node.js applications. Mongoose is a popular ODM (Object-Document Mapping) library for MongoDB that provides a simple schema-based solution for modeling your application data. In this article, we will explore how to use Mongoose with Next.js 13 for MongoDB.

Setting up Next.js 13 with Mongoose

First, you will need to install Next.js 13 and Mongoose in your project. You can do so by running the following commands in your terminal:

        
            npm install next@13 mongoose
        
    

Once Next.js and Mongoose are installed, you can connect to your MongoDB database by creating a new Mongoose connection in your Next.js application. You can do so by creating a new file, for example, db.js, and adding the following code:

        
            // db.js
            import mongoose from 'mongoose';

            const connectDB = async () => {
                try {
                    const conn = await mongoose.connect('your_mongodb_uri', {
                        useNewUrlParser: true,
                        useUnifiedTopology: true
                    });

                    console.log(`MongoDB Connected: ${conn.connection.host}`);
                } catch (err) {
                    console.error(err);
                    process.exit(1);
                }
            };

            export default connectDB;
        
    

Next, you can use the connectDB function in your Next.js pages or API routes to connect to your MongoDB database. For example, you can create a new page in your Next.js application and use Mongoose to query and manipulate your data:

        
            // pages/index.js
            import connectDB from "../db";
            import mongoose from 'mongoose';

            const Home = ({ data }) => {
                return (
                    

                        
Welcome to our Next.js application!
                        
{data}
                    
                );
            };

            export async function getServerSideProps() {
                connectDB();

                const MyModel = mongoose.model('MyModel', new mongoose.Schema({ name: String }));

                const doc = new MyModel({ name: 'John' });

                await doc.save();

                return {
                    props: {
                        data: `New document created: ${doc.name}`
                    }
                };
            }

            export default Home;
        
    

Conclusion

In this article, we have seen how to use Mongoose with Next.js 13 for MongoDB. By following these steps, you can easily connect to your MongoDB database and perform data operations using Mongoose in your Next.js application. This allows you to build powerful and scalable web applications with Next.js and MongoDB.
