How to use InflateRaw?

[mustafasalahuldin]

I need to use InflateRaw same as in pako while using zip.js, is it possible?
I can read the entry from the zip file as Byte Array, what is pending is to inflate it and show the progress.
Please advise!

You should use Entry#getData() to inflate data, see https://gildas-lormeau.github.io/zip.js/core-api.html#zip-reading.

This is not working in case I have the entry as Uint8Array.
In my case I use an HTTP request to extract the entry I need from the zip file on server, then I use pako.inflateRaw(Uint8Array) to unzip the entry(as binary), which works perfectly, the issue is pako doesn't provide the onProgress option.
So I need to do the same using zip.js, pass entry as Uint8Array then inflate it and monitor the progress.
Thanks in advance.

Just for more clarity, in my case, I'm inflate binary entry not the full zip. so there is no Central Directory.

It's here: https://github.com/gildas-lormeau/zip.js/blob/master/lib/core/codecs/inflate.js. See the class ZipInflate(options) class at the end of the file, it has an append method and a flush method that allow you to implement a progress listener. Note that pako does have a progress listener but it looks like it's undocumented. It's the abstract method onData in the object returned by new pako.Inflate() and new pako.Deflate() (see last examples here: https://github.com/nodeca/pako#examples--api).

Thanks a lot. Would you please show an example for ZipInflate(options) using Typescript? I can't define such module.

@gildas-lormeau Also I'm interested in InflateRaw() as from the documentation page, it seems there is no progress event assigned to inflate raw.
