As I was working on upgrading Legend’s custom state system for the new sync method for the new backend, I put it in a benchmark to see how fast it was, and it was only ok. That sent me down a deep rabbit hole of trying to make it faster than all the rest. The downside is it distracted me away from Legend itself for a couple of weeks, but the upside is I managed to make it faster than every other React state library and also really nice to use. I think it can help a lot of other developers so I open sourced it.
If you’re not a React developer yourself, then just know that the new backend will be faster and more stable, and Legend will get faster and faster as we migrate everything to use this new state system, and will make further development quicker ⚡️
If you are a React developer, I think you’ll like this a lot. It’s faster than all the rest (by quite a wide margin) and is a real pleasure to use. Check it out at https://legendapp.com/dev/state/
