About a year ago I wanted a fast, simple, throwaway, no sign-up/log-in To-Do List at my fingertips at work, I couldn't find one so I built one myself, in a quick and dirty way.

Recently I decided to release to public, so I rewrote, productise it a bit, added markdown support, added dark mode, added extension for chromium browsers etc, and this is it. May you find this small utility website useful if you happen to need something like this as well.

Some tech & non-tech bullets

- Pure static website

- Data goes up to URL on updating, base64 encoded, non-hashed spa style

- Rewrote with React & Redux

- ChatGPT assistance for markdown parsing, regex and its unit testing

- Playwright for testing

- CDN with AWS CloudFront

Any feedback and comments are appreciated.

A note on saving data in the URL, To-Do lists usually wouldn't be too long so saving its data in URL seems a natural fit, plus my initial sketchy research showed ff max URL is 64k and chrome can go MBs. But actually in real world, if you take server and CDNs into consideration, 8k seems to be a de facto limit (https://stackoverflow.com/a/417184), still enough for usual todo lists :)
