Napkin Notes is an encrypted, lightweight, note-taking app for quick math, short-term tasks, and temporary notes.
Hacked together by: thalida 🦄 | [email protected] | thalida.com
Napkin Notes was built over the course of a weekend as part of a solo-mission hack-a-thon. As a result, I paried down the feature set to only things I'd need when I need to quickly paste content or perform quick math during my day-to-day.
Napkin Notes is available at https://napkinnotes.app/ You can try it out anonymously, but to sync your notes across devices you'll need to create a free account!
✨ Napkin Notes is a Progressive Web App, so on supported browsers and devices you'll be able to install the app to your desktop. ✨

React's control of the dom was interferring with contenteditable components, especially once I added support for checkboxes. There was most likely an issue with my implementation, but I didn't want to spend too much time debugging.
Once React became a no-go, I tried using Svelte instead. I confirmed in the Svelte online editor that contenteditable would work with checkboxes, but I quickly got confused on how to use Svelte Kit for creating a simple application.
Since this project was a quick hack, I didn't want to spend too much time getting setup, so made the ultimate and final switch to Vue as the app's framework.
From everything I saw online (Stackoverflow), contenteditable is a headache and difficult to work with. While that was the case when figuring out how to handle custom compoents; I found it equally as challenging to find a simple text editor framework that was well supported, not behind a paywall, and allowed for easy customization.
At the end of this weekend, I'd say that I wouldn't recommend contenteditable if working on a production-grade high-traffic platform, but for a quick editor it's highly recommended!!
Django Channels doesn't seem to support token authentication by default, so I add to create my own auth token middleware for use of Django Channels to authenticate websocket requests. https://github.com/thalida/napkinnotes/blob/ee942bd460c80500b40851985d145863a2ce32dc/api/api/middleware.py
The middleware takes in the token and token_type query paramaters from the websocket request, and directly calls oauth2_provider.contrib.rest_framework.OAuth2Authentication to perform the authtentication.
