How to automatically run a .jsx script from a UXP plugin in Photoshop?

UXP Developer Tool

Hi everyone,

I’m trying to trigger an existing .jsx script automatically from within a UXP plugin in Photoshop. My goal is to let the user click a button and have Photoshop run an existing JSX script (e.g. “Mockup.jsx”) that lives in a known path (either inside the plugin folder or in Google Drive Desktop).

I’ve tried the following:

  1. shell.openExternal("file://...") → returns URI scheme "file" is not accepted
  2. shell.openPath(jsxFile.nativePath) → returns Extension ".jsx" is not accepted
  3. Using batchPlay with _obj: "open" and the path to .jsx → also blocked due to extension

I understand that UXP is sandboxed for security, but is there any supported method to trigger a .jsx file (even via bridge or a secure context)?

My setup:

  • Photoshop 25.0+
  • macOS
  • JSX file is valid and works manually via File > Scripts > Browse

Thanks in advance! Any workaround or insight would be appreciated :folded_hands:

Our intention is to keep the UXP and ExtendScript separate, so there isn’t a supported method for what you ask. We acknowledge that converting scripts from .jsx to .psjs is not a simple task. We are dealing with it internally, as well.

While there may still exist workarounds, you shouldn’t expect them to continue indefinitely.
