This module fix rotate and resize your image.
import resizer from 'image-resizer-js';
resizer(image<Uint8Array | ArrayBuffer>, maxWidth<Number>, quality<Number 0..100>, rotate<Number 0..3>)
.then(image<ArrayBuffer> => {
// image resized
const blob = new Blob([image]);
image.src = blob;
})
.catch(err => console.error(err))
Or with more options...
import resizer from 'image-resizer-js';
const options = {
maxWidth: <Number | undefined>,
maxHeight: <Number | undefined>,
quality: <Number 0..100 | undefined>,
rotate: <Number 0..3 | undefined>,
type: <String>,
silent: <Boolean>
}
resizer(image<Uint8Array | ArrayBuffer>, options)
.then(image<ArrayBuffer> => {
// image resized
const blob = new Blob([image]);
image.src = blob;
})
.catch(err => console.error(err))
Where the options.silent
is active, no logs is return if you have an error or other.
Where the options.type
is the mime type of the resulting image. The mime type defaults to image/png
so you
may want to specify images/jpeg
.

import resizer from 'image-resizer-js';
fetch('my-image.jpg')
.then(res => res.arrayBuffer())
.then(buffer => resizer(buffer, undefined, 50))
.then(buffer => {
const blob = new Blob([buffer]);
const image = new Image():
image.src = URL.createObjectURL(blob);
// ...
})
