What is difference with https://www.npmjs.com/package/node-pngquant-native package?

papandreou commented 5 years ago

node-pngquant-native is a native extension that takes and returns a Buffer, whereas node-pngquant shells out to an external binary and exposes itself as a transform stream.

node-pngquant-native should have better performance as it doesn't incur the overhead of a child process per image, but on the other hand it looks like it blocks the event loop while quantizing the image, so YMMV.

The underlying libpngquant code is the same, though, so you should end up with the same result whichever module you choose.

Both modules are rather old, but this one predates node-pngquant-native by about half a year (Dec 2012 vs. June 2013).
