Next Js Bangla Tutorial: Connect MongoDB with Next.js Bangla, Insert a Post on Mongodb | Part 8

Next.js is a popular JavaScript framework that is used to build web applications. In this tutorial, we will learn how to connect MongoDB with Next.js Bangla and how to insert a post on MongoDB.

Step 1: Create a MongoDB database

First, you need to create a MongoDB database. You can do this by signing up for a MongoDB account and creating a new cluster. Once your database is set up, you will need to note down the connection string, which will be used to connect Next.js with MongoDB.

Step 2: Connect MongoDB with Next.js

Next, you will need to install the mongoose package, which will enable you to connect to the MongoDB database from your Next.js application. You can do this by running the following command in your terminal:

npm install mongoose

Next, you will need to create a new file called db.js in your Next.js project. In this file, you will use the mongoose package to connect to your MongoDB database using the connection string you obtained earlier. Here’s an example of how you can do this:

  const mongoose = require('mongoose');

  const connectionString = 'your-mongodb-connection-string';

  const connectDB = async () => {
    try {
      await mongoose.connect(connectionString, {
        useNewUrlParser: true,
        useUnifiedTopology: true,
      });
      console.log('Connected to MongoDB');
    } catch (error) {
      console.error('Error connecting to MongoDB', error);
      process.exit(1);
    }
  };

  module.exports = connectDB;
  

Step 3: Insert a Post on MongoDB

Now that you have connected Next.js with MongoDB, you can start inserting posts into your database. First, you will need to create a model for your posts. Create a new file called Post.js in your Next.js project and define your post schema using the mongoose package:

  const mongoose = require('mongoose');

  const postSchema = new mongoose.Schema({
    title: String,
    content: String,
  });

  const Post = mongoose.model('Post', postSchema);

  module.exports = Post;
  

Now you can use this model to insert a new post into your MongoDB database. In your Next.js route or API endpoint, you can use the Post model to create and save a new post:

  const connectDB = require('./db');
  const Post = require('./Post');

  const insertPost = async (req, res) => {
    await connectDB();
    const newPost = new Post({
      title: 'New Post',
      content: 'This is the content of the new post.',
    });
    await newPost.save();
    res.json({ message: 'Post inserted successfully' });
  };

  export default insertPost;
  

By following these steps, you can connect MongoDB with Next.js Bangla and insert a post on MongoDB. This will allow you to build dynamic web applications with Next.js and store data in a MongoDB database.
