Hi, Thanks. svanderburg. How do I use nijsfunProxy?

flake this place version (master)

When will this be normal? You've already gifted us node2nix, but I hope this simpler way will be sooner rather than later. (It's really nice to be able to put it back as a nix argument right away like this)

Thanks

i've just regenerated the Nix expressions, so that broken reference should be gone now.

To try the proxy examples, the typical workflow is to clone the Git repository, and then run:

$ cd tests
$ nix-build proxytests.nix -A sum
$ cat result
3

I have never tried the flake approach before.

Keep in mind that many use-cases in NiJS were originally developed for experimentation purposes. The only "mature" aspect of NiJS is to use it as a Nix code generator.

Pure didn't work, so I moved it to .config/nixpkgs/config.nix, Again move flake.. with impure it worked fine on flake.nix. . Since js is an impure language, you wouldn't do it with flake, right? If it was changed, it would be too much work?, so I was a little reluctant to answer about it. . Even on flake it runs fine with impure anyway. . One question, is it possible to load only node modules? because.. my private hope... After making a js file (cljs, purescript, or typescript es6.js files compiled into one, it would be really good if there is a way to load and run nijsfunProxy. . And I misunderstood that nijsFunProxy could make a launcher like this in installPhase as makeWrapper $out/bin/${function} $@ . Even if that doesn't work, it doesn't matter for now (if that's the case, it would be better to create a js by yourself or give it to node directly.) . Anyway, as you said, I think you should use it for its original purpose. (so In the original nix dsl use, I wonder if the all js import of the js ecosystem is able.) So, in the future, I would like to have an interop system that easily executes something with js and the nix function receives it and processes it immediately.

Thanks.
