express multer

const multer = require('multer');
const express = require('express').Router();


/**create a folder called uploads*/
/**set up storage*/
const storage = multer.diskStorage({
  destination: (req,file,callback) => {
    callback(null, 'uploads/profileImage');
  },
  filename: (req,file,callback) => {
    const uniqueSuffix = Date.now() + '-' + Math.round(Math.random() * 1e9);
    callback(null, file.fieldname + '-' + 'image-' + uniqueSuffix);
  },
});

const fileFilter = (req,file,callback) => {
  const supportedFiles = ['image/jpeg', 'image/png'];
  if (supportedFiles.includes(file.mimetype)) {
    return callback(null, true);
  } else {
    //reject file
    return callback('Unsupported file format', false);
  }
};

const upload = multer({
  storage: storage,
  limits: { fileSize: 1000000 },
  fileFilter: fileFilter,
});


router.post('/upload-image', upload.single('thumbnail'), (req, res, next)=>{
  console.log(req.file);
	/**do something*/
});

router.post('/upload-images', upload.array('thumbnail'), (req, res, next)=>{
  console.log(req.files);
	/**do something*/
});

const multerStorage = multer.memoryStorage();

exports.uploadUserPhoto = upload.single('photo');

exports.resizeUserPhoto = (req, res, next) => {
  if (!req.file) {
    return next();
  }

  req.file.filename = `user-${req.user.id}-${Date.now()}.jpeg`;

  sharp(req.file.buffer)
    .resize(500, 500)
    .toFormat('jpeg')
    .jpeg({
      quality: 90,
    })
    .toFile(`public/img/users/${req.file.filename}`);

  next();
};
