[MongoDB](https://www.mongodb.com/) is a general purpose, document-based, distributed database built for modern application developers and for the cloud era. This example will show you how to connect to and use MongoDB as your backend for your Next.js app.

Once you have access to the environment variables you'll need, deploy the example using [Vercel](https://vercel.com?utm_source=github&utm_medium=readme&utm_campaign=next-example):
[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?project-name=with-mongodb&repository-name=with-mongodb&repository-url=https%3A%2F%2Fgithub.com%2Fvercel%2Fnext.js%2Ftree%2Fcanary%2Fexamples%2Fwith-mongodb&integration-ids=oac_jnzmjqM10gllKmSrG0SGrHOH)
Execute [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app) with [npm](https://docs.npmjs.com/cli/init), [Yarn](https://yarnpkg.com/lang/en/docs/cli/create/), or [pnpm](https://pnpm.io) to bootstrap the example:
Set up a MongoDB database either locally or with [MongoDB Atlas for free](https://mongodb.com/atlas).
### Set up environment variables
Copy the `env.local.example` file in this directory to `.env.local` (which will be ignored by Git):
```bash
cp .env.local.example .env.local
```
Set each variable on `.env.local`:
-`MONGODB_URI` - Your MongoDB connection string. If you are using [MongoDB Atlas](https://mongodb.com/atlas) you can find this by clicking the "Connect" button for your cluster.
Your app should be up and running on [http://localhost:3000](http://localhost:3000)! If it doesn't work, post on [GitHub discussions](https://github.com/vercel/next.js/discussions).
You will either see a message stating "You are connected to MongoDB" or "You are NOT connected to MongoDB". Ensure that you have provided the correct `MONGODB_URI` environment variable.
When you are successfully connected, you can refer to the [MongoDB Node.js Driver docs](https://mongodb.github.io/node-mongodb-native/3.4/tutorials/collections/) for further instructions on how to query your database.
## Deploy on Vercel
You can deploy this app to the cloud with [Vercel](https://vercel.com?utm_source=github&utm_medium=readme&utm_campaign=next-example) ([Documentation](https://nextjs.org/docs/deployment)).
To deploy your local project to Vercel, push it to GitHub/GitLab/Bitbucket and [import to Vercel](https://vercel.com/new?utm_source=github&utm_medium=readme&utm_campaign=next-example).
