To connect React.js with MongoDB, you can follow these steps:
- Install MongoDB: First, you need to install MongoDB on your machine. You can download it from the official MongoDB website and follow the installation instructions.
- Set up a MongoDB Database: Once MongoDB is installed, start the MongoDB server and create a new database using MongoDB shell or a GUI tool like MongoDB Compass.
- Set up the backend: Create a backend server using Node.js and Express.js. Install the necessary packages using npm or yarn. This server will serve as the bridge between your React.js frontend and MongoDB database.
- Connect to MongoDB: In your backend server code, import the MongoDB client package (such as 'mongodb' or 'mongoose'). Use the client to connect to your MongoDB database by providing the connection URL and other connection options.
- Define API routes: Create API routes on your backend server to handle CRUD (Create, Read, Update, Delete) operations. These routes will interact with the MongoDB database to perform data operations.
- Run the backend server: Start your backend server using the command line or your preferred IDE. Ensure that the server is running and able to connect to MongoDB.
- Integrate with React.js: In your React.js frontend, use the fetch API or third-party libraries like Axios to make HTTP requests to your backend API routes. Send requests to perform CRUD operations on the MongoDB database.
That's it! Now your React.js frontend is connected to MongoDB through your backend server, allowing you to store and retrieve data from the database.
