# --description--

In this challenge, you will import the required projects, and connect to your Atlas database.

# --instructions--

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 });
```

# --hints--

"mongodb" dependency should be in package.json

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/file/package.json').then(
    (data) => {
      var packJson = JSON.parse(data);
      assert.property(packJson.dependencies, 'mongodb');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

"mongoose" dependency should be in package.json

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/file/package.json').then(
    (data) => {
      var packJson = JSON.parse(data);
      assert.property(packJson.dependencies, 'mongoose');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```

"mongoose" should be connected to a database

```js
(getUserInput) =>
  $.get(getUserInput('url') + '/_api/is-mongoose-ok').then(
    (data) => {
      assert.isTrue(data.isMongooseOk, 'mongoose is not connected');
    },
    (xhr) => {
      throw new Error(xhr.responseText);
    }
  );
```
