How Capri Uses "Islands Architecture" for Interactivity ?
What is the "Islands" term?
Most static site generators either,
- Keep everything static means no interactivity
or
- Make everything dynamic (slow performance)
Capri solves this problem by letting you selectively add interactivity only where you need it. These interactive sections are called "Islands"
If you want a static site but need some interactivity, just name your component with .island.
For example: components/
- Header.tsx # Static component
- Counter*.island.tsx* # Interactive component
- Footer.tsx # Static component
Here, only Counter.island.tsx will have javaScript, while the rest of the page remains pure HTML/CSS.
