Question

What is the process for linking my Next.js application with MongoDB Compass?

Currently, I am working on a project in Next.js called NetMapper where I am developing a web interface for the CLI tool nmap. My main focus right now is creating Sign In/Sign Up forms and storing user information in MongoDB Compass. Despite trying various tutorials from YouTube, I am facing challenges in establishing a connection to MongoDB Compass. Although I have developed Schemas and Models for users, I am unable to successfully connect to the MongoDB Compass database.

To address this issue, I have installed mongoose.

My attempt so far:

const connectDb = async () => mongoose.connect("mongodb://localhost:27017/netmapper);

What steps should I take next? How can I effectively utilize the Model I created to insert data from the form into the database?

Answer №1

Start by creating a .env.local file at the root and saving database credentials inside

MONGO_URI=mongodb://localhost:27017/netmapper

If the above code doesn't work, change localhost to 0.0.0.0

Establish a connection to MongoDB

    async function connectToMongo() {
    try {
         await mongoose.connect(process.env.MONGO_URI);
         console.log("Connected to MongoDB");
       } catch (error) {
         console.error("Error connecting to MongoDB:", error);
         throw error;
        }
    };

Create a schema for your data

    const testSchema = new Schema({
       name: String,
       email: String
    });

    const Test = models.Test|| model("Test", testSchema );

Handle incoming requests and send responses by setting up an api/xyz.js file

async function handler(req, res) {
    if (req.method === "POST") {
        const data = req.body;

        try {
            await connectToMongo();
            await Test.create(data);

            res.status(201).json({ message: "Data Inserted!" });
        } catch (error) {
            res.status(500).json({ message: "Internal Server Error" });
        }
    }
};

Finally, submit your form data

 async function submitFormHandler(formData) {
    const response = await fetch("/api/xyz", {
      method: "POST",
      body: JSON.stringify(formData),
      headers: {
        "Content-Type": "application/json"
      }
    });

    const data = await response.json();
    console.log(data)
  }
