Answer 1

Express uses connect middleware, you can specify the file upload size by using the following

app.use(express.limit('4M'));

Connect Limit middleware

Answer 2

// Comment sart   
// app.use(express.bodyParser({
//    uploadDir:'./Temp',
//    maxFieldsSize:'2 * 1024 * 1024 * 1024 ',
// }));  

// Add this code for maximun 150mb 
app.use(bodyParser.json({limit: '150mb'}));
app.use(bodyParser.urlencoded({     // to support URL-encoded bodies
limit: '150mb',
extended: true
})); 

// I did it Okay. Goood luck 

Answer 3

app.use(express.limit('4mb'));

But you must make sure you add this line above the below,

app.use(express.bodyParser());

or

app.use(express.json());
app.use(express.urlencoded());

depending on which version you are using.

Answer 4

I'm using Express 4. I tried numerous app.use() statements, including the non-deprecated ones listed on this thread, but none of them worked.

Instead, it turned out I only needed to add one line to index.js to change the maxFileSize option in the Formidable module:

// create an incoming form object
var form = new formidable.IncomingForm();

// ADD THIS LINE to increase file size limit to 10 GB; default is 200 MB
form.maxFileSize = 10 * 1024 * 1024 * 1024;

Answer 5

var upload = multer({ storage : storage2, limits: { fileSize: 1024 * 1024 * 50 } });

correct format for increasing file uploading size with multer in nodejs
