Integrating MongoDB and Mongoose with Nuxt 3
Building dynamic web applications often requires seamless integration with a robust database solution. When it comes to creating powerful server-side applications, MongoDB has emerged as a popular choice among developers due to its flexibility and scalability. Combined with the Vue.js framework, Nuxt.js provides a solid foundation for building fast, server-rendered applications. However, incorporating MongoDB and its object modeling tool, Mongoose, into a Nuxt project might seem like a daunting task for those new to the stack.
In this blog post, we'll explore two simple yet effective methods to add MongoDB and Mongoose to your Nuxt 3 project. Whether you're a seasoned developer or just starting your journey in full-stack web development, this guide will help you leverage the capabilities of MongoDB and Mongoose within the Nuxt ecosystem.
Prerequisites
Before we get started, make sure you have a working nuxt 3 project. If you don't have one already, you can create a new project using the following command:
npx nuxi init <project-name>
Once the project is created, navigate to the project directory and install the dependencies:
cd <project-name>
npm install // or yarn install
Now that we have a working nuxt 3 project, let's explore the two methods of adding MongoDB and Mongoose to our project.
Method 1: Using the nuxt-server-utils module
This is the easiest way to add MongoDB and Mongoose to your Nuxt 3 project. The nuxt-server-utils module provides a set of utilities that allow you to interact with your MongoDB database from within your Nuxt 3 application. It also provides a simple API for creating and managing your MongoDB collections.
To get started, install the nuxt-server-utils module using the following command:
npm install nuxt-server-utils mongoose
Next, Add the nuxt-server-utils module to the modules
section of your nuxt.config.ts
file:
Add nuxt-server-utils
to the modules
section of nuxt.config.ts
:
export default defineNuxtConfig({
// ...
modules: ["nuxt-server-utils"],
});
Finally, add the MongoDB connection string to the .env
file of your nuxt app:
MONGODB_URI=<your-mongodb-connection-string>
That's it! Now you can use mongoose in your Nuxt 3 server routes like how it is normally used in Express. For example, let's create a simple server route that returns all the documents from a MongoDB collection:
Defining the Mongoose model in server/models/user.model.ts
:
import { Schema, model } from "mongoose";
const UserSchema = new Schema({
name: String,
email: String,
});
export const User = model("User", UserSchema);
Now let's create the API Route in server/api/users.get.ts
:
import { User } from "~~/server/models/user.model";
export default defineEventHandler(async (event) => {
const users = await User.find();
return Users;
});
If you navigate to the /api/users
route, you should see a list of all the users in your database.

Method 2: Creating a Nitro plugin
Nuxt 3 uses Nitro under the hood to power its server-side rendering capabilities. Nitro provides a simple API for creating plugins that can be used to extend the functionality of your Nuxt 3 application. In this section, we'll create a Nitro plugin that will allow us to use MongoDB and Mongoose in our Nuxt 3 project.
First, let's create a new plugin file in the server/plugins
directory:
touch server/plugins/mongodb.ts
Then let's install the required dependencies:
npm install mongoose
Next, let's add the following code to the newly created plugin file:
import { Nitro } from "nitropack";
import mongoose from "mongoose";
export default async (_nitroApp: Nitro) => {
const config = useRuntimeConfig();
try {
await mongoose.connect(config.mongodbUri);
console.log("Connected to MongoDB");
} catch (e) {
console.error(e);
}
};
Finally, let's add the plugin to the plugins
section of our nuxt.config.ts
file:
export default defineNuxtConfig({
// ...
nitro: {
plugins: ["~/server/plugins/mongodb.ts"],
},
});
That's it! Now you can use mongoose in your Nuxt 3 server routes like how it is normally used in Express.
