cd serviceworker-rendering

Note that you will need to have Node.js installed.

Install the dependencies...

cd serviceworker-rendering
npm install

...then build with Rollup:

npm run build

npm start

Navigate to localhost:5000. You should see your app running.

SWSR is based on Svelte component and Vanilla Javascript. It use Svelte as component compiler and a rendering based on Vanilla Javascript.

It implement the YAGNI Extreme programming paradigm into DOM. It just render what we need and anthing else.

In index.html is instantiate into navigator.serviceWorker render.js the render engine of the application.

This solution code is a PoC of a render system based on service worker dynamic creation of http response (a PHP rendering idea into the sw).

When the render sw is installed it caches the static files of the svelte components compiled. On a navigate request it create JiT a html response with an html content based on the request url. It also checked each fetch function to retrurn cached files.
