Node.js Question

Get download progress in Node.js with request

I'm creating an updater that downloads application files using the Node module "request". How can I use chunk.length to estimate the remaining file size? Here's part of my code:

var file_url = 'http://foo.com/bar.zip';
var out = fs.createWriteStream('baz.zip');

var req = request({
method: 'GET',
uri: file_url

req.on('data', function (chunk)

req.on('end', function()
//Do something

Answer Source

This should get you the total you want:

req.on( 'response', function ( data ) {
    console.log( data.headers[ 'content-length' ] );
} );

I get a content length of 9404541
