extendscript-bundler

0.0.6 verified Sat Apr 25 auth: no javascript abandoned

A development-time bundler for creating ExtendScript + ScriptUI panels for Adobe Creative Cloud applications (After Effects, Premiere Pro, Photoshop, etc.) on macOS. v0.0.6 (latest) is pre-1.0 and not actively maintained; the package has not seen updates since 2020. Key differentiators: provides live reload via AppleScript + browserify bundling, enabling a hot-reload-like workflow by reusing the global Window instance. Windows support is not available; the package is macOS-only.

Common errors

error Error: Cannot find module 'extendscript-bundler' ↓

cause Package is not installed globally; running as npx without installation first.

fix

Run 'npm install -g extendscript-bundler' or use 'npx extendscript-bundler' (without local install).

error Error: spawn osascript ENOENT ↓

cause AppleScript runtime not available (not on macOS or osascript missing).

fix

This tool only works on macOS. Ensure you are running on macOS with osascript in PATH.

Warnings

breaking macOS only – Windows support is not implemented. ↓

fix Use on macOS only, or look for alternative tools like 'Adobe ExtendScript Toolkit' or webpack-based solutions.

deprecated Package is unmaintained since 2020 and may not work with newer Adobe applications or Node.js versions. ↓

fix Consider using Adobe UXP or CEP-based tools for modern development.

gotcha Requires the 'extendscript-starter' project for live reload (optional, but strongly recommended). ↓

fix Clone https://github.com/adobe-extension-tools/extendscript-starter and follow its setup.

gotcha Live reload relies on AppleScript; ensure 'osascript' is accessible and that the Adobe application is running. ↓

fix Make sure the target Adobe application (e.g., After Effects) is open and scripting is enabled.

Install

npm install extendscript-bundler

yarn add extendscript-bundler

This package is primarily a CLI tool, not a library. It does not export any JavaScript API for programmatic use.

Quickstart

Bundles an ExtendScript entry file into a single .jsx file and evaluates it in the specified Adobe application.
