Use your Raspberry Pi Camera Module with Node.js

pi-camera-native

• Forked to fix errors/crashes to do with buffer recycling (esp. on stop), re-entrancy, menory-leak fixes and expand the API
• Includes Typescript type definitions
• All dependencies have also been updated

Use your Raspberry Pi Camera Module with Node.js

NOTE: Currently only supports image capture and live preview as MJPEG

Prerequisites

• Hardware

  • Raspberry Pi
  • Raspberry Pi Camera module

• Software

  • Raspberry Pi camera enabled
  • Node.js 8 or later installed

Install

npm install pi-camera-native-ts --only=prod 

npm install pi-camera-native-ts will also install development dependencies, but you're probably better off with git clone https://github.com/MatAtBread/pi-camera-native.git && cd pi-camera-native && npm i

Usage

// require module
const raspberryPiCamera = require(pi-camera-native-ts);

// add frame data event listener
raspberryPiCamera.on('frame', (frameData) => {
  // frameData is a Node.js Buffer
  // ...
});

// start capture
raspberryPiCamera.start({
  width: 1920,
  height: 1080,
  fps: 20,
  encoding: 'JPEG',
  quality: 12,
  rotation: 0,
  mirror: Mirror.NONE
});

import camera from 'pi-camera-native-ts';
....
await camera.start({
  width: 1920,
  height: 1080,
  fps: 20,
  encoding: 'JPEG',
  quality: 12,
  rotation: 0,
  mirror: Mirror.NONE
});

const jpegData = await camera.nextFrame();

await camera.stop();
