Package Exports

request-image-size

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (request-image-size) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

request-image-size

Detects image dimensions via request instead of Node.js native http/https, allowing for options and following redirects by default. It reduces network traffic by aborting requests as soon as image-size is able to obtain the image size.

Since version 2.0.0 it returns an ES6 native Promise that resolves with the size object or rejects with an Error. Requires Node.js v4+.

If you prefer using a callback, please use version 1.3.0 instead (docs)

Supports all the image formats supported by image-size:

BMP
CUR
GIF
ICO
JPEG
PNG
PSD
TIFF
WebP
SVG
DDS

Dependencies

Basic usage

const requestImageSize = require('request-image-size');

requestImageSize('http://nodejs.org/images/logo.png')
.then(size => console.log(size))
.catch(err => console.error(err));

Result:

{ width: 245, height: 66, type: 'png', downloaded: 856 }

Advanced usage

Specifying a request options object (docs):

const requestImageSize = require('request-image-size');

const options = {
  url: 'http://nodejs.org/images/logo.png',
  headers: {
    'User-Agent': 'request-image-size'
  }
};

requestImageSize(options)
.then(size => console.log(size))
.catch(err => console.error(err));
