How to Remove Documents Using Node.js Mongoose 🚀💻

Are you struggling to remove documents using Node.js Mongoose? Don't worry, you're not alone! In this guide, we'll explain why the provided code snippet doesn't work and provide you with a simple solution to remove documents effectively. Let's dive in! 🏊‍♂️

The Problem 🤔

Let's take a look at the code snippet provided:

FBFriendModel.find({
    id: 333
}, function (err, docs) {
    docs.remove(); // Remove all the documents that match!
});

The intention of the code is to remove all the documents that match the specified ID. However, the code doesn't seem to be working as expected, and the records are still present.

The Solution ✅

The issue lies in the usage of the remove() method. In Mongoose, the remove() method is used to remove a single document, not multiple documents. To remove multiple documents, we need to use the deleteMany() method instead. Let's update the code accordingly:

FBFriendModel.deleteMany({
    id: 333
}, function (err) {
    if (err) {
        console.error(err);
    } else {
        console.log("Documents successfully removed!");
    }
});

In the updated code, we're using the deleteMany() method instead of remove(). This method removes all the documents that match the specified criteria, in this case, the ID being equal to 333. Additionally, we've also added error handling to ensure any potential errors are logged.

Now, when you run this code, it will successfully remove all the documents that match the provided criteria.
