Smart Time Ago: a new JS lib to update relative timestamps more efficiently (opens in new tab)

It depends on the application itself. For pages which user will only stay for few minutes, no much more efficiency gained. But for realtime apps which user will keep the page open for hours/days, it will improve a lot. And for apps which have more read than write, it will also improve a lot. BTW, I'm not sure whether I catch you about the "extra code". It's a replacement with less than 1KB difference in size.

It's different. While momentjs focus on date parsing, manipulating and formatting, smart-time-ago is the lib to update the relative timestamps in time on the page.

Yup. Ryan did a great job on the timeago lib. We have ever discussed about the pull request but finally find that we changed lots of the logic about how to deal with the relative timestamp. So we started a new one to give an optional choice.

The simple solution to this is that the server sends a reference time along with the timestamps: when the page loads you calculate the drift from the local time to the reference time, and then adjust local time to server time when you update relative timestamps.

It looks interesting. Thanks for the info. Just watched. :D
