Hi Derek,

I 'think' there are currently a couple of ways of achieving this, depending on your use case:

- **In the Node-RED dashboard** : recently version [2.10.0](https://discourse.nodered.org/t/announce-dashboard-version-2-10-0/4196) of the Node-RED dashboard was released, which offers a Widget API. That can be used to create your own widget in the dashboard. In the .js file, there is a HTML function where you can generate Javascript code (as a string) that will run in the browser.

- **In the Node-RED flow editor** : every Node-RED node can have Javascript that runs in the browser (as defined in it's .html file), but that is - I think - only active when you have the node's config screen open.

Perhaps you can explain a bit more what you are trying to build ...
