These notifications are delivered directly to your device, ensuring you stay updated even if you’re not actively using the website.
Concept 3: How Service Workers Work
Service workers operate as a middle layer between your browser and the website you’re visiting. When you first visit a website that uses service workers, the browser downloads the service worker script and installs it on your device. This script acts as a background process that runs independently of the website.
Once the service worker is installed, it can intercept network requests made by the website. For example, if you click on a link or submit a form, the service worker can intercept that request and decide how to handle it. If you’re offline, the service worker can respond with the cached version of the website’s content instead of making a request to the server.
Service workers also have the ability to update themselves. This means that when you revisit a website, the service worker can check for updates and install a new version if available. This ensures that you always have the latest version of the website, even if you haven’t visited it recently.
It’s important to note that service workers only work with websites that have been designed to support them. Website developers need to implement specific code and configure the service worker to enable offline functionality. So not all websites will have service workers, but as more developers adopt this technology, we can expect to see an increase in websites that provide offline experiences.
