Get frame from MotionEye
Need to install npm nodeFetch and follow this guide: https://nodered.org/docs/user-guide/context
const nodeFetch = context.global.get('nodeFetch');
const fs = context.global.get('fs');
const url = 'http://my.motion.eye.url./picture/2/current';
const getRandomIntInclusive = (min, max) => {
min = Math.ceil(min);
max = Math.floor(max);
return Math.floor(Math.random() * (max - min + 1) + min);
};
const pictureFilename = `${new Date().getTime()}_${getRandomIntInclusive(0, 9999).toString().padStart(4, 0)}.jpg`;
const savePath = "/tmp/";
const fullPath = `${savePath}${pictureFilename}`;
const res = await nodeFetch(url);
const fileStream = fs.createWriteStream(`${savePath}${pictureFilename}`);
await new Promise((resolve, reject) => {
res.body.pipe(fileStream);
res.body.on("error", reject);
fileStream.on("finish", resolve);
});
// Do what you want with it the photo. Image path is: fullPath
// Delete image after 3 seconds
setTimeout(() => {
fs.unlink(fullPath, () => {});
}, 3000);
return msg;
