# --description--
在 package.json 文件中添加 mongodb 和 mongoose 作为项目依赖,然后引入 Mongoose。之后将 MongoDB Atlas 的 URI 作为 MONGO_URI 字段存储在私有的 `.env` 文件中。然后使用单引号或双引号包裹 URI最后通过以下的代码片段来连接数据库
```js
mongoose.connect(<Your URI>, { useNewUrlParser: true, useUnifiedTopology: true });
```
# --hints--
"mongodb" 应在 package.json 中作为依赖项定义
```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" 应在 package.json 中作为依赖项定义
```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);
}
);
```
应使用 "mongoose" 连接数据库
```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);
}
);
```
# --solutions--
```js
/**
Backend challenges don't need solutions,
because they would need to be tested against a full working project.
