I managed to fit a hacky text editor inside a URL [0] without too many issues, and I didn't bother with any minification or custom packing of the data. So you can easily take it a lot further!
I found there were a lot of edge cases with data URIs that made sharing them kinda annoying. Like email providers stripping the data URI when you email it (not getting spam-binned. The link would get deleted. Even if you left it as a plain text email.)
Firefox doesn't appear to have a URL length limit. Unfortunately, the world is standardising on Chrome, and that absolutely does (about 2,097,152 characters for the entire URI). Chrome also _sometimes_, but not always, opens a data:text/html link in Quirks Mode.
Good info thank you! Yeah I’ve noticed some weird stripping behavior in some clients like iMessage and Slack. Not sure if it’s the encoding or the length of the string that is my current issue but they both seem to play a role.
