Dev Environment - Nix Edition

Reproducible development environment using Nix flakes with modern tools and smart defaults.

Prerequisites

Install Nix and Git on your system:

Nix

sh <(curl -L https://nixos.org/nix/install) --daemon

Git - https://git-scm.com/install/

Setup

1. Clone this repository:

git clone https://github.com/devanandersen/env.git ~/env
cd ~/env

2. Enable flakes:

Add

experimental-features = nix-command flakes

to whatever is existing, see

cat ~/.config/nix/nix.conf
cat /etc/nix/nix.conf
cat /nix/var/nix/profiles/default/etc/nix/nix.conf

3. Apply the configuration:

sudo systemctl restart nix-daemon

For Mac (Apple Silicon):

nix run home-manager/master -- switch --flake .#devan

For Linux:

  nix run home-manager/master -- switch --flake .#devanandersen@x86_64-linux

After the initial installation on Apple Silicon, you can use the nix-update alias from anywhere to apply configuration changes.
