I'm using Multer/multer-storage-cloudinary to upload images directly to Cloudinary rather first uploading it to a local temp directory, then sending it to Cloudinary:
const express = require('express');
const router = express.Router({mergeParams:true});
if (app.get('env') == 'development'){ require('dotenv').config(); }
const crypto = require('crypto');
const cloudinary = require('cloudinary').v2;
const { CloudinaryStorage } = require('multer-storage-cloudinary');
const multer = require('multer');
const { storage } = require('../cloudinary');
const upload = multer({storage});
//configure cloudinary upload settings
cloudinary.config({
cloud_name:process.env.CLOUDINARY_NAME,
api_key: process.env.CLOUDINARY_API_KEY,
api_secret: process.env.CLOUDINARY_API_SECRET
});
const storage = new CloudinaryStorage({
cloudinary: cloudinary,
folder: ('book_tracker/'+process.env.CLOUDINARY_FOLDER+'posts'),
allowedFormats: ['jpeg', 'jpg', 'png'],
filename: function (req, file, cb) {
let buf = crypto.randomBytes(16);
buf = buf.toString('hex');
let uniqFileName = file.originalname.replace(/\.jpeg|\.jpg|\.png/ig, '');
uniqFileName += buf;
console.log(req.body);
cb(undefined, uniqFileName );
}
});
const middleware = {
function asyncErrorHandler: (fn) =>
(req, res, next) => {
Promise.resolve(fn(req, res, next))
.catch(next);
}
}
/* POST create user page */
router.post('/register', upload.single('image'), asyncErrorHandler(postRegister));
What I'm running into is that the response I'm getting in req.file
is not the full Cloudinary response which includes public_id, etc. Instead it's like this:
{
fieldname: 'image',
originalname: 'My Headshot.jpg',
encoding: '7bit',
mimetype: 'image/jpeg',
path: 'https://res.cloudinary.com/<cloudinary_name>/image/upload/v1611267647/<public_id>.jpg',
size: 379632,
filename: '<public_id>'
}
It's been a while since I worked with multer-storage-cloudinary, though that storage
was taken directly from an old project that would return the correct information. Is there something in multer, or multer-storage-cloudinary, that I need to set in order to put the full cloudinary response into req.file?
The multer-storage-cloudinary
package is a third party package that integrates multer and Cloudinary in a streamlined way, but it doesn't expose all possible options or responses from the Cloudinary SDK or API
In your example, it's not returning the full API response from Cloudinary, but a subset of the fields, because the file
object's filename
, path
, and size
properties are taken from the Cloudinary API response (from the public_id
, secure_url
, and bytes
properties of the API response respectively), but the other fields aren't mapped: https://github.com/affanshahid/multer-storage-cloudinary#file-properties
If you need the full set of response values (or some specific values not mapped already) you can:
