## What it is
PuerTS is a multi-language scripting solution from Tencent that embeds JavaScript/TypeScript (and, for Unity, Lua and Python) runtimes into Unity, Unreal Engine, and .NET applications. It provides high-performance C#/C++ interop and generates TypeScript declarations for type-safe access to host engine APIs.

## Use cases
- write Unity game logic in TypeScript
- script Unreal Engine gameplay with JavaScript
- embed a V8 or QuickJS runtime in a .NET application
- use npm packages inside a Unity game
- hot-reload game scripts without recompiling the engine
- mix Lua, Python, and TypeScript in one Unity project
- generate TypeScript typings for Unity or Unreal APIs

## When to choose
- your team prefers TypeScript/JavaScript over C++ or C# for game logic
- you want to leverage the npm ecosystem inside Unity or Unreal
- you need a fast, type-safe scripting layer with native interop
- you want to mix multiple scripting languages in a Unity project

## When to avoid
- you need a purely C#/C++ codebase with no scripting layer
- your target platform cannot ship a JS engine runtime
- you only need simple config scripting where Lua alone suffices
- you require Unreal support for languages other than JavaScript/TypeScript

## Facets
- artifact type: library
- maturity: active
- function: interpreter, sdk, plugin-system
- domain: programming-languages, cross-platform
- platform: cpp, c, dotnet, game-engine, cross-platform
- tags: typescript, javascript-engine, v8, quickjs, unity, unreal-engine, scripting, interop, lua, python, game-development
