Runtime improvements

Native VitaJS modules are now maintained through a centralized module definition system. New modules can be registered without manually updating multiple parts of the runtime bootstrap.

JavaScript source files are evaluated as ES modules, allowing applications to be split into multiple files using standard import / export syntax.

QuickJS

The embedded QuickJS runtime has been upgraded to the 2026-06-04 release while preserving VitaJS-specific module loading and PlayStation Vita path handling.

New native modules

The runtime now includes:

  • Screen
  • Pads
  • Font
  • Audio
  • Net
  • System
  • App
  • Dialog
  • Power
  • std
  • os

Installation

Download vitajs-v0.4.0.vpk below and install it on your PS Vita.

VitaJS is still experimental. APIs may change between releases and testing on real PS Vita hardware is recommended.
