				+# Notes App
			
 
				+
			
 
				+This is a notes web app that uses WebDAV to store plaintext files that can be
			
 
				+synced to a remote server.
			
 
				+
			
 
				+The reason for storing the notes on the filesystem and exposing via WebDAV is to
			
 
				+make editing with any editor possible.
			
 
				+
			
 
				+It's a precursor that lead to [The Notes App](https://harlanji.gumroad.com/l/the-notes-app).
			
 
				+
			
 
				+## Requirements
			
 
				+
			
 
				+* ExtJS 2.0.2 stored in or linked from the ext-2.0.2 path of each day.
			
 
				+* Nginx with the DAV extension enabled
			
 
				+* An .htpasswd file with at least one user confured in it (via apache tools).
			
 
				+* Optionally lsyncd
			
 
				+
			
 
				+I believe the password in the provided .htpasswd files is demo123, pardon if I'm mistaken.
			
 
				+
			
 
				+## Usage
			
 
				+
			
 
				+The script `setup-deb-bullseye.sh` can be used to install a site to nginx,
			
 
				+or followed for nginx installation on any other platform.
			
 
				+
			
 
				+The `sync-notes` script can be used to run lsync, manually or via a cron job.
			
 
				+
			
 
				+## Dev Practice
			
 
				+
			
 
				+This is an older demo from when I was just establishing the habit of breaking 
			
 
				+practice into a daily format.
			
 
				+
			
 
				+It focuses on:
			
 
				+
			
 
				+* Making minimal code changes from a prior demo
			
 
				+* Getting an app running in Nginx 
			
 
				+* Nginx DAV storage
			
 
				+* Syncing info to a remote server with LSyncd
			
 
				+
			
 
				+The code is messy and intentionally left so because it's derived from an earlier 
			
 
				+work, which I mean to create a minimal diff from and sequentially commit to Git.
			
 
				+Please pardon the apparently amateur style. Releasing as-is to the dev-practice repo.
			
 
				+
			
 
				+## Changelog
			
 
				+
			
 
				+### 2023-05-21
			
 
				+
			
 
				+Updated README for release in harlanji/dev-practice repo.
			
 
				+
			
 
				+### Day 3
			
 
				+
			
 
				+* Added Lunr code to index in browser and/or nodejs given notes
			
 
				+
			
 
				+TODO
			
 
				+
			
 
				+* Save notes as paintext and load them as plaintext (this would enable easy import).
			
 
				+* Create a way to change storage location for cross-site
			
 
				+* Either mount the webdav FS for node to index remote notes
			
 
				+* Or create an iterator over notes in the store to download all content.
			
 
				+
			
 
				+
			
 
				+
			
 
				+### 2022-01-16
			
 
				+
			
 
				+* Added cross-origin support to nginx config
			
 
				+* Updated code to work cross origin
			
 
				+
			
 
				+### 2022-01-15
			
 
				+
			
 
				+* Created baseline notes demo
			
 
				+* Created nginx config with webdav
			
 
				+* Created install script
			
 
				+* Created Lsyncd config
