    uploadDir:'./Temp',
    maxFieldsSize:'2 * 1024 * 1024 * 1024 ',
}));

am not sure how to set the maxFieldsSize property, need some help!!!

Answer 1

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

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

Answer 2

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.
