Nix flake templates for dev environments

Use nix flake to make dev environments reproducible (e.g. tools, environment variables, init scripts).

This repository is heavily inspired by the-nix-way/dev-templates and tailored for personal preferences.

Prerequisites

Install Nix and enable the following experimental features:

nix.settings.experimental-features = [ "nix-command" "flakes" ];

Get started

# To initialize (where `ENV` is listed in the table below):
nix flake init --template github:whisperpine/dev-templates#ENV

# Here's an example (for the rust template):
nix flake init --template github:whisperpine/dev-templates#rust
# To ensure it's up to date, use `--refresh`:
nix flake init --refresh --template github:whisperpine/dev-templates#rust

How to use the templates

Once your preferred template has been initialized, you can use the provided shell in two ways:

• If you have nix-direnv installed, you can initialize the environment by running direnv allow.
• If you don't have nix-direnv installed, you can run nix develop to enter the nix-defined shell environment.

Available templates

# list all the templates (notice items under "templates"):
nix flake show github:whisperpine/dev-templates

• empty: a good start point for any projects.
• golang: manage golang toolchain with configurable versions.
• python: python virtual environment managed by uv.
  Notice the shellHook "source .venv/bin/activate", which is essential.
• rust: manage rust toolchain, targets and others tools.
  It supersedes the functions of rustup in a declarative way.
• web: web or nodejs dev environment managed by bun.
  Notice web/.envrc extends PATH environment variable.
