# MongoDB and Mongoose with Next.js

This example shows how you can use a MongoDB database to support your Next.js application.

**Pet** is an application that allows users to add their pets' information (e.g., name, owner's name, diet, age, dislikes, likes, and photo). They can also delete it or edit it anytime.

## Deploy your own

[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https://github.com/vercel/next.js/tree/canary/examples/with-mongodb-mongoose&project-name=with-mongodb-mongoose&repository-name=with-mongodb-mongoose&env=MONGODB_URI&envDescription=Required%20to%20connect%20the%20app%20with%20MongoDB&envLink=https://github.com/vercel/next.js/tree/canary/examples/with-mongodb-mongoose%23step-2-set-up-environment-variables)

## How to use

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:

```bash
npx create-next-app --example with-mongodb-mongoose with-mongodb-mongoose-app
```

```bash
yarn create next-app --example with-mongodb-mongoose with-mongodb-mongoose-app
```

```bash
pnpm create next-app --example with-mongodb-mongoose with-mongodb-mongoose-app
```

## Configuration

### Step 1. Get the connection string of your MongoDB server

In the case of MongoDB Atlas, it should be a string like this:

```
mongodb+srv://<username>:<password>@my-project-abc123.mongodb.net/test?retryWrites=true&w=majority
```

For more details, follow this [MongoDB Guide](https://docs.mongodb.com/guides/server/drivers/) on how to connect to MongoDB.

### Step 2. 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
```

Then set each variable on `.env.local`:

- `MONGODB_URI` should be the MongoDB connection string you got from step 1.

### Step 3. Run Next.js in development mode

```bash
npm install
npm run dev
# or
yarn install
yarn dev
# or
pnpm install
pnpm dev
```

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).

## 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)).

#### Deploy Your Local Project

To deploy your local project to Vercel, push it to GitHub/GitLab/Bitbucket and [import to Vercel](https://vercel.com/import/git?utm_source=github&utm_medium=readme&utm_campaign=next-example).

**Important**: When you import your project on Vercel, make sure to click on **Environment Variables** and set them to match your `.env.local` file.
