multer

I use multer . Question 1 When I put the following snippet in the app.js app.use(multer({ dest: './uploads' } ).single('file')); it creates a new folder under the root folder, my question is about this new folder's lifeCycle, When it'll be deleted? How much the size of the folder could be after 100 call? Question 2 If I don't want to limit the file size, what I should put in the configuration? app.use(multer({ dest: './public/profile/img/', limits: { fieldNameSize: 50, files: 1, fields: 5, fileSize: 1024 * 1024 }, Update My app is built like app.js file contain app.use(multer({ dest: '.

I am using expressjs 4.0 along with multer to handle file uploads. Problem is, I want to stop file upload when the file's size exceeds a maxSize variable. But multer uploads file anyways. Is there a way to stop this behaviour. Some example code : app.post('/upload', function(req, res) { var maxSize = 32 * 1000 * 1000 // 32mb max if(req.files.file.length > maxSize) { // stop upload } else { // continue res.send(201); } }); LorenzoGi According to Multer documentation: ( https://www.npmjs.org/package/multer ) you could use onFileUploadStart(file), and return false if the size is above your limit.

I have this express route with multer file-upload. When the upload is complete, I would like to encode the image to base64 and send with response. However when I do it like this, the code tries to execute the base64 encoding before the file is created to the folder. Edit : Added storage & upload functions const storage = multer.diskStorage({ destination: (req, file, callback) => { if (!fs.existsSync('./uploads')) { fs.mkdirSync('./uploads'); } let path = './uploads'; callback(null, path); }, filename(req, file, cb) { let fileExt = file.originalname.substring(file.originalname.lastIndexOf('.'))
