Prepare the environment

1. Install Node.js v16.9+. To install it without a headache, use NVM (Node Version Manager). You can run something like this:

   # Install NVM itself
   curl -o- https://raw.github.com/nvm-sh/nvm/v0.39.1/install.sh | bash
   
   # Run it to use NVM in the current shell session or restart your shell
   export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
   [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

   Then you can install Node 18:

   nvm install 18

2. Enable Corepack:

   corepack enable

3. Install project dependencies. From the root of the cloned repository, run:

   pnpm install

Run dev mode

pnpm dev

It will start a local dev-server. You will be able to open a browser, observe rendered documentation, edit source files and see your edits on-demand.

Formatting

We use Prettier to format project sources. Its configuration is located at ./.prettierrc.js. Check options reference for all available options.

• Format sources: apply formatting to all project source files:

  pnpm format:fix

• Check the formatting in sources: ensure that all project source files match Prettier code style

  pnpm format:check

We use prettier-eslint tool to override Prettier formatting for Vue components.

Linting

To check whether ESLint rules pass, run:

pnpm lint

To fix auto-fixable issues, run:

pnpm lint --fix

Testing

We use Vitest test framework to assure quality of non-trivial internal parts of the project.

To check whether tests pass, run:

pnpm vitest run

To run vitest in a watch-mode, run:

pnpm vitest

Enabling feedback form

In order to enable the "Share feedback" button, the following environment variable should be provided:

VITE_FEEDBACK_URL=https://example.com/get-feedback

When a user submits the form, a simple POST request with a JSON body is sent to this URL.

This variable will be picked up by the application during dev/build mode. Read more about it in the Vite documentation.
