# 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 Once you have access to [the environment variables you'll need](#step-2-set-up-environment-variables), 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?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://:@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 ``` 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. #### Deploy from Our Template Alternatively, you can deploy using our template by clicking on the Deploy button below.
