alejandra VS dream2nix

I hope someone using lazy.nvim, has a setup they can share, where they are using alejandra as their nix formmater. I've read the instruction, but can't get it to work other than using the manual command. Hoping to integrate it into the LSP automatically.

Flakes are best imported from other flakes, but if your system configuration isn’t a flake, you can use builtins.getFlake to load it, like (builtins.getFlake "git+https://github.com/kamadorueda/alejandra?rev=d00d03f0b45d2d1d6e0ae2d110c821b497d8fb09").packages.x86_64-linux.default gives you the alejandra package.

As others have mentioned, there are a couple of LSP implementations. There's also statix for basic static analysis, as well as a few formatters, including nixpkgs-fmt and alejandra.

(I'm on the flox team) we'd love to support that and it's something we've talked about! We already support auto-generation for some languages like Rust because they have a lockfile (e.g. Cargo.lock), but it's a bit trickier for a requirements.txt. We hope at some point to contribute to/integrate with upstream efforts like dream2nix which have auto-generation as their goal

How about dream2nix? I like to use the nix way, but there are many third nix ways

I'm not 100% sure, but looking at the docs [here](https://nix-community.github.io/dream2nix/subsystems/node.html#granular-pure-default) and the implementation [here](https://github.com/nix-community/dream2nix/tree/main/src/subsystems/nodejs/builders/granular-nodejs) it seems as it builds dependencies separately and symlinks (see `install-deps.py` those into a `node_modules` tree. I don't know much about Yarn's PNP (was doing more backend/devex last few years), but it sounds vaguely similar in that each package should be built once as a separate derivation and then symlinked to a big `node_modules`-as-a-symlink-tree derivation?

How are you building your NodeJS project with Nix right now? Recently I spot a new abstraction, it looks good but I havn't tried it yet: https://github.com/nix-community/dream2nix

dream2nix is a great package, that makes a nix-derivation out of node project with the minimal flake

The DavHau/dream2nix project aims to be a generic solution for this issue by splitting the problem into specific stages, each of which can be configured individually (e.g., changing the level of purity)
