perf(#3231): decrease setup time: optimise setup and defer requires until tree open by alex-courtis · Pull Request #3308 · nvim-tree/nvim-tree.lua

alex-courtis · 2026-03-30T23:27:42Z

nvim-tree is now completely lazy on startup and requires the minimum when:

requiring api / registering events
requiring nvim-tree
calling setup

setup time ~1ms, down from ~8ms, see #3229 timings

@przepompownia @perrin4869 I would be most grateful for your testing of this branch, ensuring that the load times have been significantly reduced.

Using minimal config:

require("nvim-tree.api")

paste -sd+ <(grep "require('nvim-tree\." /tmp/startuptime | cut -d ' ' -f 5 | sed -E 's/:$//g') | bc
1.347

Can we expect anyone to still use Nvim 0.9?

Apparently yes, for debian users.

I did receive some pushback when I recently discussed increasing the minimum version, although I cannot find that conversation.

It's not a problem right now, however I will revisit if it becomes a problem.

Edit: I think upgrading might be difficult for people on locked down corporate computers or remote environments.

Debian 12.13 (current oldstable) has Nvim 0.7.2, Debian 13.3 has 0.10.4-8. I didn't check other distros.

https://github.com/search?q=repo%3Anvim-tree%2Fnvim-tree.lua+%220.9%22&type=issues&s=created&o=desc - rather nothing relatively fresh.

@alex-courtis thanks for the great job! I'll try to find a time to compare startup times. Now I only switched to this change and see no issues.

For two months I changed my lazy loader to even packadd some plugins on demand (being aware of the unavailability of command definitions etc.), but thanks to the recent changes here, I can also expect improved performance during use (not only at the Nvim startup).
