Instalation
npm install image-size
Usage
var sizeOf = require('image-size');
var dimensions = sizeOf('images/funny-cats.png');
console.log(dimensions.width, dimensions.height);
Async version
var sizeOf = require('image-size');
sizeOf('images/funny-cats.png', function (err, dimensions) {
console.log(dimensions.width, dimensions.height);
});
Using a url
var url = require('url');
var http = require('http');
var sizeOf = require('image-size');
var imgUrl = 'http://my-amazing-website.com/image.jpeg';
var options = url.parse(imgUrl);
http.get(options, function (response) {
var chunks = [];
response.on('data', function (chunk) {
chunks.push(chunk);
}).on('end', function() {
var buffer = Buffer.concat(chunks);
console.log(sizeOf(buffer));
});
});
You can optionally check the buffer lengths & stop downloading the image after a few kilobytes.
You don't need to download the entire image

Credits
not a direct port, but an attempt to have something like
dabble's imagesize as a node module.
