It is time 🕑

I did not share much about Rocket recently but it's going great 💪

It's now in beta and if you have been curious before then it's a good time to check it out.


What has happened since the last update?

1️⃣ Engine version became the main release
2️⃣ @rocket/components for SSR & hydration
3️⃣ Rewrite of themes (@rocket/launch & @rocket/spark)
4️⃣ rocket preview
5️⃣ rocket lint

Let's take a closer look.

Main release

The journey from the first prototype to a dedicated package to adding build time SSR to supporting hydration has been challenging but also very rewarding.

Rocket is the first SSG that enables you to write your whole page in template literals and web components. 💪

✨ Rocket highlights ✨

✍️ Author in Markdown, HTML or JS
🚀 Build everything in Web Components
🪶 Ship 0 JS for Web Components by default
🌊 Hydrate Web Components as needed
🎨 Theme System
🖼️ Social Media Images
✅ Link Checking

@rocket/components for SSR & hydration

➡️ Very early but it makes the existing themes so fast
➡️ All components are rendered on the server and can be hydrated if needed
➡️ Add to components and use them
➡️ Docs are lacking 🙈 see source (for now)

👉 site/pages/

import { rocketComponents } from '@rocket/components/components.js';

export const components = {
  'my-counter': '#src/components/MyCounter.js::MyCounter',

👉 site/pages/index.rocket.html

<h1>Welcome to My Page</h1>

  <span slot="summary"> I'm often asked by parents</span>
    what advice can I give them to help get kids interested in science? And I have only one bit of
    advice. Get out of their way. Kids are born curious. Period.

📖 The Documentation Theme (Launch)

➡️ Starts with ~2kb of main thread js (+ ~3kb for service worker)
➡️ Hydrates components as needed
➡️ Works without JavaScript if Declarative Shadow Dom (DSD) is supported
➡️ awesome performance
➡️ Example: preview lighthouse webpage test waterfall

✨ The Landing Page Theme (Spark)

➡️ Similar characteristics to Launch
➡️ Uses 8 web components
➡️ Only 1 gets hydrated at start
➡️ Example: preview

🕑 Getting started

🕑 Getting started with any theme takes you only 5 minutes
🏃‍♂️ Run "npx @rocket/create@latest" in the terminal
🎯 Choose your template and start coding!

PS: It creates a folder for you now worries 🤗

rocket preview

With rocket preview we can check after a production build if everything is in order.

➡️ Uses a plain web server without any features
➡️ If it works there then _site is good to ship to your production web server

👀 Previewing Production Build

  🚧 Local:    http://localhost:8000/
  🌐 Network:
  📝 Source:   /projects/rocket/_site

If what you see works as expected then you can upload "source" to your production web server.

rocket lint

Launching a new site and the first feedback is "this link is broken" 🙈

Not anymore with rocket lint 💪

➡️ Checks asset urls like css, images, scripts, ...
➡️ Checks internal links (incl. if ids exist for anchors)
➡️ It is fast and can/should be used in the CI

npx rocket lint
👀 Checking if all internal links work...
🔥 Found a total of 57 files to check!
🔗 Found a total of 4401 links to validate!

✅ All internal links are valid. (executed in 0s 299.021433ms)


npx rocket lint
👀 Checking if all internal links work...
🔥 Found a total of 57 files to check!
🔗 Found a total of 4401 links to validate!

❌ Found 1 missing reference targets (used by 1 links) while checking 57 files:
  1. missing reference target _site/docs/basics/super-pages/index.html
    from _site/docs/guides/index.html:1213:15 via href="/docs/basics/super-pages/"

Checking links duration: 0s 296.371296ms

There are two modes:

1️⃣ Check the production build in _site (need to execute "rocket build" before)
2️⃣ Run a fast html only build and then check it

Use 1️⃣ in your CI and 2️⃣ while fixing links locally

# use this in CI
# check existing production build in _site (need to execute "rocket build" before)
rocket lint

# use this while fixing broken links
# run a fast html only build and then check it
rocket lint --build-html

That's all folks! 🤗
