New site, new repo.

This is a Lerna monorepo.

• lit-dev-content: Main content of lit.dev
• lit-dev-server: Production web server for lit.dev
• lit-dev-tools: Eleventy plugins and other internal tools

npm i && npm run bootstrap

npm run build

npm run dev

Serves at http://localhost:5415.

You may also prefer to run each dev script in its own terminal:

cd packages/lit-dev-content

npm run build:ts:watch       # TypeScript
npm run dev:build:site:watch # Eleventy
npm run dev:serve            # @web/dev-server

Dev mode is different to production in these ways:

• Browser auto-reload.
• CSS is not inlined or minified. CSS changes are reflected immediately.
• JS is not inlined, bundled, bare-module transformed, or minified. JS changes are reflected immediately after tsc compile.
• HTML is not minified.

If needed, you can check for dev mode from an Eleventy template using the env.DEV global:

{% if env.DEV %}
  <p>Dev mode</p>
{% else %}
  <p>Prod mode</p>
{% endif %}

First run npm run dev as shown above, and then in another terminal:

cd packages/lit-dev-api
npm run build:watch

You can now edit the comments in any .ts file in the lit directory, and after the automatic rebuild, the dev site will refresh.

code packages/lit-dev-api/lit/

The lit directory is a regular cloned git repo, so you can make changes directly here, and push PRs from it as normal. It's configured to track the main branch, but is pinned to a particular commit via the lit.sha file. To update the current commit, run:

cd packages/lit-dev-tools
npm run monorepo:update

npm run build
npm start

Serves at http://localhost:6415

npm start # production server

cd packages/lit-dev-content
npm run build:ts:watch     # TypeScript
npm run build:rollup:watch # Rollup
npm run build:site:watch   # Eleventy

Screenshots that are committed to the repository need to be created through the "Artifacts / Download link for updated screenshots" Github Action. This action generates a zip archive golden-results which can be extracted into tests/.

unzip golden-results.zip -d tests/
