Danielo,
I explored using noteself as a replacement for tiddlyfox saving. IOW, I did
not use the couchdb server functionality. I faced some issues which I share
below:
Issues 3 and 7 seem to be pouchdb/noteself specific, the rest might be
fundamental issues with the skinny tiddler approach. I guess even 3 is
skinny tiddler related.
1. *Feedback on import progress* - I used the browse widget to select a
tiddlywiki file with over 1000 tiddlers and it wasn't easy to tell that the
import was still in progress. Not realizing it was still in progress, I
refreshed the page only to discover after careful inspection that the
import was incomplete. Finally I learned I could tell the import was
complete in one of two ways
1. During the import the save button stays solid red and it loses the
color once the import is complete
2. Open the javascript console and wait for the import messages to
stop
2. *importvariables widget* doesn't work unless all the tiddlers being
imported are opened manually ahead of time
3. *Drafts* - directly opening a draft is empty. "Directly opening a
draft" happens when you have a tiddler in draft mode (and it gets saved
that way) and then you refresh the browser. Steps to reproduce:
1. open wiki and create a new tiddler, adding some text to the body
2. leave it in edit mode and refresh the TW browser page
3. click on the "Draft of 'New tiddler'" link in the recent tab
4. the tiddler will be empty (i.e. the body text is lost)
- This is a data-loss situation...I didn't find a way via tiddlywiki to
recover the draft contents. Probably the data is somewhere in pouchdb,
but
I didn't dig into it.
4. *Shadow version of some tiddlers wreaks havoc*
- I use the codemirror plugin with vim mode and its use of the Escape
key conflicted with cancelling edits, so I had a modified
$:/core/ui/EditTemplate wherein I changed the cancel key to Ctrl-Escape.
For some reason (probably a good reason), having a shadow version of a
tiddler causes a periodic scan (20-30 seconds maybe?) into pouchdb for
changes. Whether there were any changes found or not, all the tiddlers in
the scan list get refreshed. Refreshing the edit template while there are
any drafts open causes focus to move from the text body and into the
title
and the title is selected. If typing is going on, then the title ends up
getting deleted and replaced by that typing. I found the newest version
of
TW has keyboard configuration which obsoletes my need for the shadow
instance of the Edit Template
- TLDR: Don't store shadow instances of Edit Template in the pouchdb
5. *Having lots of tiddlers loaded really slows things down* - with
my >1000 tiddler TW instance it became very slow if all the tiddlers get
loaded. For example, if I hit the save button in order to get a json export
of the TW, that would cause all the tiddlers to be loaded. It would also
cause >1000 periodic scans to pouchdb for changes to these tiddlers. I
would have to refresh the browser page after exporting to json in order to
not suffer slowdowns.
6. *Manual load of any tiddler required before accessing anything other
than title field*. This affects
1. Search can only match on titles
2. Any list filters matching against fields other than title field. I
have several pieces of custom functionality which use such filters
7. *Export from search broken* - I decided to move my changes back into
a non-pouchdb TW, but found the menu which allows export to .csv, .json,
.tid, etc. was broken. Instead of downloading the results of the search in
the requested format, the entire TW was downloaded only in json format.
Seemed like the export was taking the same functionality as the Save button
in the sidebar. I ended up dragging the tiddlers one-by-one into the other
TW instance. Only a dozen or so, so it wasn't too bad.
This was a fun experiment...thanks for sharing your work.
Brian
