Unreal.js is an Unreal Engine plugin that embeds a V8-powered JavaScript runtime, giving scripts full access to the Unreal Engine API with live reload and debugging support. It supports CommonJS modules, npm libraries, editor extension bridges, and auto-generated TypeScript definitions for VS Code.

Use cases

• script unreal engine gameplay logic in javascript
• extend the unreal editor with javascript tools
• hot-reload game scripts without recompiling c++
• subclass blueprints and engine classes from javascript
• debug javascript inside unreal with vscode or webstorm
• use npm libraries inside unreal engine projects

When to choose

• your team prefers javascript over c++ or blueprints for game logic
• you need rapid iteration with live-reloaded scripts in unreal engine
• you want to reuse existing javascript libraries in a game project

When to avoid

• you target unreal engine versions beyond 5.1 or need guaranteed ongoing support
• you need maximum runtime performance from compiled native code
• your project requires a permissively documented license for commercial review
