Doughnut is a Personal Knowledge Management (PKM) tool combining zettelkasten style of knowledge capture with some features to enhance learning (spaced-repetition, smart reminders) and ability to share knowledge bits with other people (for buddy/team learning).

Story Map

🏁 From the root of doughnut directory, in a terminal, run:

Please ensure your git configuration is appropriate for your OS to respect the correct line endings:

git config --global core.autocrlf input
git add --renormalize .

Install Nix package manager if you haven't already with

./setup-doughnut-dev.sh

Install direnv and activate direnv macOS: brew install direnv Ubuntu/Debian (includes WSL2 with Ubuntu): sudo apt-get install -y direnv Fedora: sudo dnf install direnv Change directory to your cloned doughnut folder path and run the below:

echo 'eval "$(direnv hook bash)"' >> ~/.bashrc
echo 'eval "$(direnv hook zsh)"' >> ~/.zshrc
direnv allow

Subsequently, each time your change directory into your doughnut cloned folder, nix flakes will be auto loaded. Each time you change directory away from doughnut directory, the nix environment will be auto unloaded.

Ensure your OS (WSL2/Ubuntu/Fedora, etc) has /bin/sh point to bash. If you are using Ubuntu where /bin/sh is symlinked to dash, please run sudo dpkg-reconfigure dash and answer "No" to reconfigure to bash as default.

🪟 WSL2 with WSLg:

⚠️ Nix and sdkman don't play very well together. A simple way around is to move or rename ~/.sdkman dir and comment out sdkman related config in ~/.<SHELL>rc.

🚦 🚧 ONLY if you hit problems with the above quick-start setup, you should manually walk through the local development environment nix setup.

From the root of your doughnut directory, start your doughnut nix development environment with

If you have direnv installed & configured right, just cd to the path where you cloned doughnut Github source code and the nix develop environment will autoload, OTHERWISE run:

nix develop

Start the backend service/application

pnpm sut

• Rerun it each time you reset the database or change backend java code (java is still a compiled language).

• From doughnut source root directory:

pnpm backend:verify

We use cucumber Gherkin + cypress (test driver) Javascript/Typescript framework to drive the end-to-end test suite.

• Cucumber

The Cypress+Cucumber tests are in JavaScript/TypeScript.

cypress

• cypress-cucumber-preprocessor

• We use mountebank to mock external backend services.

  • To run mountebank in debug mode, run pnpm mb --loglevel debug.

For MS Windows WSL2 users:

1. you need to ensure your WSL2 Linux has xvfb installed manually before you can run cypress. This is not managed by Nix!
2. export NODE_OPTIONS="--max-old-space-size=4096" before running any cypress related commands ( e.g. cy:open or cy:run).

You can find the database migrations in backend/src/main/resources/db/migration/. The migrations are run automatically when the backend app starts up. It will also run the migrations for test when you run pnpm backend:test. To trigger the test DB migration manually, run backend/gradlew migrateTestDB. To connect to the local DB: mysql -S $MYSQL_HOME/mysql.sock -u doughnut -p (password=doughnut).

We chose Vue3 + Vite to build our frontend.

The TypeScript code calling the backend services is generated from the backend code. Run

pnpm generateTypeScript

To do the code generation. There are two steps in this command:

1. Generate openAPI docs from the backend service into ./open_api_docs.yaml.
2. Generate TypeScript interfaces from the openAPI docs, into frontend/src/generated.

If the step 1 is not done, a unit test will fail. If the step 2 is not done, CI will fail (./assert_generated_type_script_up_to_date.sh).

From doughnut source root directory

pnpm frontend:verify

pnpm frontend:sut

pnpm frontend:build
pnpm sut

Expect to find minified and uglified web bundle assets in backend/src/main/resources/static directory:

❯ pwd
/home/lia/doughnut/backend/src/main/resources/static
❯ tree -L 3
.

│   └── vendor.8f9eb49d.js

1 directory, 6 files

When you have the backend and frontend running, you can manually test the application.

Visit http:https://localhost:5173/ to see the frontend web-app. The backend API is available at http:https://localhost:9081, and you will see the built frontend web-app there as well, but it wil not auto-reload on changes. So stay with the 5173 port.

• pnpm: To clean up packages installed by pnpm, you can run pnpm store prune to remove unused packages from the store. To remove all packages for a specific project, navigate to the project directory and run pnpm recursive uninstall to uninstall all dependencies in the project and its subdirectories.
• direnv: To stop direnv from automatically loading the environment, you can simply delete the .envrc/ file in the project directory or run direnv deny in the project directory. To uninstall direnv, use the package manager you installed it with (e.g., brew uninstall direnv for macOS).
• Nix: If you want to remove the Nix package manager and all packages installed through it, you can run sudo rm -rf /nix to delete the Nix store. To uninstall Nix completely, follow the official Nix documentation for uninstallation instructions.
