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
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 }
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));
