Nix allows users to easily use over 80,000 Linux packages in a repl.
Nix opens the door to many exciting tools and applications on the platform.
Our goal is for every repl to be backed by Nix.
Before we can do that, we need to ensure that the Nix experience is just as good, if not better, than our existing Polygott solution .
If you've used a Nix repl, you may have noticed additional loading time when opening your repl.
The console would show "Loading Nix environment..." and you'd have to wait for a few seconds.
In some cases, you might have waited for tens of seconds.
We care about making repls start up as fast as possible and this additional loading time wasn't acceptable.
Through some additional caching, we have entirely removed this loading time on many Nix repls.
Now, Nix repls will start up just as fast as Polygott-based repls.
See below for a before and after demonstration.
Before: After: With this improvement, we are even closer to being able to transition all repls to Nix without causing any regressions in performance and usability.
