How to disable compression of a newly created ZIP?

[drauch]

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

Best regards,

You have to set the option level to 0 when creating a ZipWriter instance or when calling the add method.

See here for an example of code:

zip.js/tests/all/test-store.js

Line 15 in eb89a9c

const entry = await zipWriter.add(FILENAME, new zip.BlobReader(BLOB), { level: 0 });

See here for the documentation: https://gildas-lormeau.github.io/zip.js/api/interfaces/ZipWriterConstructorOptions.html#level.
