node-raylib

Node.js bindings for raylib, a simple and easy-to-use library to enjoy videogames programming (www.raylib.com).

Examples

Dependencies

• Node.js >= 10

Usage

1. Create a new Node.js project:

   mkdir myexample
   cd myexample

2. Create a package.json file with:

   {
     "dependencies": {
       "raylib": "*"
     },
     "scripts": {
         "start": "node index.js"
     }
   }

3. Create a index.js JavaScript file, like core_basic_window.js:

   const r = require('raylib')
   
   const screenWidth = 800
   const screenHeight = 450
   r.InitWindow(screenWidth, screenHeight, "raylib [core] example - basic window")
   r.SetTargetFPS(60)
   
   while (!r.WindowShouldClose()) {
       r.BeginDrawing();
       r.ClearBackground(r.RAYWHITE)
       r.DrawText("Congrats! You created your first node-raylib window!", 120, 200, 20, r.LIGHTGRAY)
       r.EndDrawing()
   }
   r.CloseWindow()

4. Have npm install the dependencies for you:

   npm install

5. Run index.js through Node.js:

   npm start

   

Check for more examples organized by raylib modules.

Installation

Raylib is implemented as bindings with node-addon-api. Bindings are prebuilt for many platforms in Releases. If your platform is not supported by a prebuilt binary, you will need CMake to build the native addon. Windows users building manually will also require MSVC Build Tools 2019, or Visual Studio 2019 with build tools for C/C++.

In general, to install node-raylib locally, use npm:

npm install raylib

DRM

On some ARM devices like Raspberry PI, raylib can be used in a DRM mode instead of rendering to an x11 window. This version requires a seperate native addon, and on installation on ARM devices node-raylib will include both. To use the DRM mode, import raylib/drm instead.

import * as rl from 'raylib/drm/index.js'
const rl = require('raylib/drm')

CLI

The project comes with a node-raylib command-line tool to run node-raylib files directly:

# Unix
./bin/node-raylib core_basic_window.js

# Windows
node bin/node-raylib core_basic_window.js

The CLI can be installed globally through npm or npx for no-install:

npm install raylib --global
node-raylib --version
npx -y raylib --version

Development

node-addon-api is used to construct the bindings. Raylib provides a header parser that generates a JSON file containing information on the API. The code binding raylib to NodeJS is automatically generated based on this file. For information on how bindings are written for raylib read the documentation. Code generators for the C++ bindings, TypeScript definitions, and JavaScript wrapper functions are found in the tools/generate_templates folder.

Testing

Run the following to run tests...

git clone https://github.com/RobLoach/node-raylib.git
cd node-raylib
npm i
npm t

TypeScript Definitions

Typescript definitions are provided by a generator based on raylib's header parser. See node-raylib-definitions.js for information on how to generate them.

Package

To build the packaged releases, use the following command:

npm run pkg
