Thumbnail

Generate a smaller preview image from an image, video, or document.

File-first​

thumbnail() requires both width and height. The fit option (max / crop / scale) controls how the source is fitted to those dimensions. Omitting either is rejected with a GislConfigError before any upload — there is no wasted round trip.

const result = await client
  .file('./photo.jpg')
  .thumbnail({ width: 200, height: 200 })
  .run({ maxWait: '5m' });

console.log(result.url);

Chaining​

Thumbnail the output of a prior step in the same workflow — for example, compress first, then thumbnail the compressed result:

import { OptimizeFor } from '@giveitsmaller/sdk';

const result = await client
  .file('./photo.jpg')
  .compress(OptimizeFor.Size)
  .thumbnail({ width: 200, height: 200 })
  .run({ maxWait: '5m' });
