MEANJS : 413 (Request Entity Too Large)

I am using a MEANJS stack, I upload an image using ng-flow and save the imgsrc as base64 url.


Here is my mongoose schema:

var ServiceSchema = new mongoose.Schema({
name : String,
url: String,
description : String,
category : String,
imgsrc: String

I run into a Request Entity Too Large server error for large images.

I could resize the image prior to upload but this still only allows me image of size 200 x 200

$scope.resizeimageforupload = function(img){
var canvas = document.getElementById('canvas');

var MAX_WIDTH = 200; //400; too big still
var MAX_HEIGHT = 200; //300 too big still
var width = img.width;
var height = img.height;

if (width > height) {
if (width > MAX_WIDTH) {
height *= MAX_WIDTH / width;
width = MAX_WIDTH;
} else {
if (height > MAX_HEIGHT) {
width *= MAX_HEIGHT / height;
height = MAX_HEIGHT;
canvas.width = width;
canvas.height = height;
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0, width, height);

var dataURL = canvas.toDataURL("image/png");
dataURL.replace(/^data:image\/(png|jpg);base64,/, "");

return dataURL;

Any ideas on a work around or alternate solution ?

Answer Source

You can add following to express config:

app.use(bodyParser.urlencoded({limit: '50mb'}));
app.use(bodyParser.json({limit: '50mb'}));

Basically you need to configure Express webserver to accept bigger request size. Replace 50mb with whatever maxsize you want to accept.

Hope this helps!!!
