# azure.function中的package引用

因為需要部署雲端，依存關係無法手動處理（無伺服器特性沒可能去執行npm安裝...）

需於設定檔寫依賴\
下面範例引用「streamifier（v0.1.1）」

{% code title="index.js" %}

```
const streamifier = require('streamifier');
```

{% endcode %}

{% code title="package.json" %}

```
{
  "name": "FunctionName",
  "version": "1.0.0",
  "description": "",
  "scripts": {
    "start": "func start",
    "test": "echo \"No tests yet...\""
  },
  "author": "Dinoin",
  "dependencies": {
    "streamifier": "^0.1.1"
  },
  "devDependencies": {}
}
```

{% endcode %}

package.json在function專案資料夾中，理論上是專案中所有function共用。

{% hint style="danger" %}
推測可能於每一次無服務啟動時進行下載，說不定對啟動效能有影響，需要再觀察。
{% endhint %}
