**Why download the js agent locally?**  
In some cases, there might be connectivity issues/limitations that prevent the successful download of the javascript agent (ruxitagentjs). In this case, you can save the script locally and build the application accordingly.

**Here are the steps to do so:**  
1. You can download the script/file from the web application via the WebUI or API. If via UI you can find it under the **W**** eb Application → Settings → Setup.**

Note: This application must be the matching web application for your hybrid/mobile application

2. Save the file locally (in any directory).&nbsp;Note that you can name the file whatever you want but the file and directory that you use needs to exist. The file downloaded from the WebUI will be named&nbsp;jsSnippet.txt&nbsp;by default.

3. There are 2 ways to build the app:&nbsp;  
&nbsp; &nbsp; &nbsp; &nbsp;- Via the custom configurations in the dynatrace.config.js. Your config.js will look like the screenshot below:

Then you can build the application as you normally would by running “ **cordova build android/ios** ”.

- Via custom Command Line Interface (CLI) arguments:

```auto
cordova build android <span>--jsagent=C:/path/to/jsSnippet.txt</span>

```

**Note:** &nbsp;If both&nbsp; custom CLI arguments and custom configuration arguments are used, custom CLI arguments will be used.
