# --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);
|
||
}
|
||
);
|
||
```
