Building a Web Application with Nix (An Experimental Attempt)

·2021.07.16 09:00

Key point

This introduces an experimental method of building a web application by leveraging the functional programming features of the package manager **Nix**.

Details

Nix, a package manager and reproducible build system, was not originally designed for web development. However, since Nix is itself a complete functional programming language, code can be executed directly through its built-in interpreter without going through a package build process.

Rather than using Nix directly as a web server, this experimental project uses a regular web server to invoke the nix eval command.

The implementation works as follows:

  • default.nix: Defines a Nix function that has HTML content as an attribute.
  • Python server: Uses subprocess to run the nix eval --raw -f ./app get command and returns the resulting value as HTML.

Through this process, it demonstrates a unique structure that runs a web application by leveraging Nix's functional programming characteristics.
