Local development machine development environment setup with nix

⚠️ 🚨 ONLY PROCEED with the subsequent steps if ./setup-doughnut-dev.sh (see README.md) somehow failed for you!!!

1. Install Lix

We use Lix (a variant of Nix package manager) to manage and ensure a reproducible development environment (https://lix.systems/).

Full details on Lix installation via lix-installer here

curl --proto '=https' --tlsv1.2 -sSf -L https://install.lix.systems/lix | sh -s -- install

2. Setup and run doughnut for the first time (local development profile)

mkdir -p ~/.config/nix
echo 'experimental-features = nix-command flakes' >> ~/.config/nix/nix.conf

Launch a new terminal in your favourite shell (I highly recommend zsh). Clone full all-in-one doughnut codebase from Github (Microsoft Windows OS users, please clone the repo to a non-Windows mount directory)

git config --global core.autocrlf input
git clone [email protected]:nerds-odd-e/doughnut.git
git add --renormalize .

Boot up your doughnut development environment. MySQL DB server wil be started and initialised on entering the local cloned doughnut source directory via direnv else run nix develop.

cd doughnut

All development tool commands henceforth should work when in the nix development environment that will be bootstrapped by direnv (if installed and configured correctly), else run nix develop to get the necessary tooling installed correctly. Run E2E profile springboot backend server with gradle (backend app started on port 9081)

# from doughnut source root dir
pnpm sut

Open your browser to visit http://localhost:9081

Run backend unit tests

# from doughnut source root dir
pnpm backend:verify

Run frontend unit tests

# from doughnut source root dir
pnpm frontend:verify

Run E2E profile with backend server & frontend in dev mode & Cypress IDE (frontend app on port 5173; backend app on port 9081)

⚠️ For MS Windows users, you need to ensure your WSL2 Linux has xvfb installed. This is not managed by Nix! (see Additional things to note for Microsoft Windows10/Windows11 developers using WSL2g with Ubuntu-23.04.)
# from doughnut source root dir
pnpm test:open

Run headless E2E (doughnut full stack started on port 9081)

# from doughnut source root dir
pnpm verify

3. Upgrade Lix

You can upgrade Lix with:

sudo -i nix upgrade-nix

4. Uninstalling

I hope you don't, but IF YOU REALLY REALLY NEED TO, you can remove a lix-installer-installed Nix by running

/nix/lix-installer uninstall
