Description

Specific implementation steps

  1. Add a link to how to install nix in Linux and MacOS and WSL in README.md.

  2. Add flake.nix to the template and demo

  3. flake.nix uses devenv and direnv as well as flake-parts, provides package management tools such as bun or pnpm, adds node-lts runtime, and enables postgres services

  4. Describe the startup command in README

Contributor guide

Research direction
First, review current repository setup for any existing Nix configuration (e.g., shell.nix). Then, create a new flake.nix in the template and demo directories using devenv, direnv, and flake parts as building blocks. Include package management with bun or pnpm, add node lts runtime, and enable PostgreSQL service. Finally, update README.md with installation instructions for Nix and the startup command.
