# KaraDAV - A lightweight WebDAV server, with NextCloud compatibility
2022-09-03 03:08:52 +00:00
This is WebDAV server, allowing to easily set up a WebDAV file sharing server compatible with NextCloud clients with no depencies and high performance.
2022-08-31 06:06:27 +00:00
2022-09-03 03:08:52 +00:00
The only dependency is SQLite3 for the database.
2022-08-31 06:06:27 +00:00
Although this is a demo, this can be used as a simple but powerful file sharing server.
This server features:
2022-09-30 17:35:04 +00:00
* User-friendly directory listings for file browsing with a web browser:
* Upload directly from browser
* Rename
* Delete
* Create and edit text file
* MarkDown live preview
* Preview of images, text, MarkDown and PDF
2022-09-03 03:08:52 +00:00
* WebDAV class 1, 2, 3 support, support for Etags
2022-08-31 06:06:27 +00:00
* No database is required
* Multiple user accounts
* Share files for users using WebDAV: delete, create, update, mkdir, get, list
* Compatible with WebDAV clients
2022-09-04 00:27:40 +00:00
* Support for HTTP ranges (partial download)
2022-09-30 00:42:21 +00:00
* Support for [RFC 3230 ](https://greenbytes.de/tech/webdav/rfc3230.xhtml ) to get the MD5 digest hash of a file (to check integrity) on `HEAD` requests (only MD5 is supported so far)
* Support for `Content-MD5` with `PUT` requests, see [dCache documentation for details ](https://dcache.org/old/manuals/UserGuide-6.0/webdav.shtml#checksums )
* Support for some of the [Microsoft proprietary properties ](https://greenbytes.de/tech/webdav/webdavfaq.html )
2022-09-30 17:35:04 +00:00
* Passes [Litmus compliance tests ](https://github.com/tolsen/litmus ) for basic, copymove, props
2022-08-31 06:06:27 +00:00
2022-09-04 00:27:40 +00:00
## NextCloud compatibility
* Android app
* Desktop app (tested on Debian)
* [NextCloud CLI client ](https://docs.nextcloud.com/desktop/3.5/advancedusage.html )
* Support for [Direct download API ](https://docs.nextcloud.com/server/latest/developer_manual/client_apis/OCS/ocs-api-overview.html#direct-download )
2022-09-30 13:17:47 +00:00
* Support for [Chunk upload ](https://docs.nextcloud.com/server/latest/developer_manual/client_apis/WebDAV/chunking.html )
2022-09-04 00:27:40 +00:00
2022-09-29 23:39:24 +00:00
## WebDAV clients compatibility
* [FUSE webdavfs ](https://github.com/miquels/webdavfs ) is recommended for Linux
* davfs2 is NOT recommended: it is very slow, and it is using a local cache, meaning changing a file locally may not be synced to the server for a few minutes, leading to things getting out of sync. If you have to use it, at least disable locks, by setting `use_locks=0` in the config.
2022-08-31 06:06:27 +00:00
## Future development
2022-09-03 03:08:52 +00:00
This might get supported in future (maybe):
2022-09-29 23:39:24 +00:00
* [Partial upload via PATCH ](https://github.com/miquels/webdav-handler-rs/blob/master/doc/SABREDAV-partialupdate.md )
2022-09-04 00:27:40 +00:00
* [NextCloud Trashbin ](https://docs.nextcloud.com/server/latest/developer_manual/client_apis/WebDAV/trashbin.html )
* [NextCloud sharing ](https://docs.nextcloud.com/server/latest/developer_manual/client_apis/OCS/ocs-share-api.html ) (maybe?)
2022-09-29 23:39:24 +00:00
* [WebDAV sharing ](https://evertpot.com/webdav-caldav-carddav-sharing/ )
2022-09-03 03:08:52 +00:00
* [Extended MKCOL ](https://www.rfc-editor.org/rfc/rfc5689 ) if CalDAV support is implemented
2022-09-29 23:39:24 +00:00
* CalDAV/CardDAV support: maybe, [why not ](https://evertpot.com/227/ ), we'll see, in the mean time see [Sabre/DAV ](https://sabre.io/dav/ ) for that.
2022-08-31 06:06:27 +00:00
## Dependencies
This depends on the KD2\WebDAV and KD2\WebDAV_NextCloud classes from the [KD2FW package ](https://fossil.kd2.org/kd2fw/ ), which are packaged in this repository.
2022-09-03 03:08:52 +00:00
They are lightweight and easy to use in your own software to add support for WebDAV and NextCloud clients to your software.
