Add `mongodb` and `mongoose` to the project’ s `package.json` . Then, require mongoose as `mongoose` in `myApp.js` . Store your MongoDB Atlas database URI in a private `.env` file as `MONGO_URI` . Surround the the URI with single or double quotes, and make sure no space exists between both the variable and the `=` , and the value and `=` . Connect to the database using the following syntax:
```js
mongoose.connect(< Your URI > , { useNewUrlParser: true, useUnifiedTopology: true });
```
