Support OPDS

Open kelson42 opened this issue 6 years ago • 6 comments

OPDS is the new way to deliver the ZIM catalog. See https://wiki.kiwix.org/wiki/OPDS Would that be possible to support OPDS in Kiwix JS?

@kelson42 Three questions about this (related to Kiwix JS Windows, which has an implementation of a download library):

  1. Are there plans to deprecate direct browsing of http://download.kiwix.org/zim/ for directories and filenames? I currently scrape those indices for filenames in Kiwix JS Windows. Not the right way, I know... NB I get the download links from the .meta4 file, so users of the app have a choice of mirrors.

  2. Currently I can get the torrent for a given ZIM by adding .torrent instead of .meta4 on the filename, and this works. Can I still rely on that?

  3. Have all "split" versions of ZIM files been deprecated (*.zimaa *.zimbb etc.)? There are now only quite old files in http://download.kiwix.org/zim/portable/. If so, I should remove my "portable" links.

I know the right way is to query the catalog, but it may take some time to develop...

Yes

Listing and downloading ZIM files from the app is currently not implemented in kiwix-js. We simply point to https://download.kiwix.org/zim/. @Jaifroid has implemented some logic inside kiwix-js-windows (without OPDS)

The OPDS stream has been strongly developed and as soon as libkiwix10 is release (in a few days) should be considered ready to use. A pure OPDS reader is now available in kiwix serve welcome page.

@kelson42 Is the pure OPDS reader implemented in JS, do you know?

@Jaifroid yes, you can try it by downloading a nightly build of kiwix-serve. The js code is in the libkiwix for the moment. I'm perfectly aware that such a piece of software/js library would benefit to many of our solutions and therefore if your are happy with it we could/should consider to isolate it to simplify maintenance/integration.
