As part of an investigation, we have attempted to create an example that could suit our needs.

Using the following as a basic example…

const sharp = require("sharp");

(async () => {
  console.log("Starting >>>");

  const buffer = await sharp("./test.gif", {
    animated: true,
  })
    .resize(60)
    .gif({
      pageHeight: 60,
    })
    .toFile("resized.gif");
})();

Removing resize and ‘pageHeight’, produce a working animated gif.

However, with resize and pageHeight included, the following is generated…

This was tested on macOs 10.15.7, ideally we may be able to continue with a proof of concept and more comprehensive instructions on how to add configuration.

Perhaps waiting for the next iteration here https://github.com/lovell/sharp/issues/2275 could be a potential solution
