I just want to use the "archive" feature of ZIP and put some files into a ZIP, how to forego compression?

Best regards, D.R.

You have to set the option level to 0.

See here for an example of code: https://github.com/gildas-lormeau/zip.js/blob/eb89a9c2448bd13637a86cb60c8784c33b5ae43f/tests/all/test-store.js#L15. See here for the documentation: https://gildas-lormeau.github.io/zip.js/api/interfaces/ZipWriterConstructorOptions.html#level.
