# What are Service Workers (and why might you want one)? | |
Service Workers are a new technology in modern web browsers. They augment the normal web deployment model and empower applications to deliver reliability and performance on par with natively installed code. | |
Service Workers have many different capabilities, but the most important is their function as a network proxy. They intercept all outgoing HTTP requests made by the application and can choose how to respond to them. For example, they can query a local cache and deliver a cached response if one is available. Proxying isn't limited to requests made through programmatic APIs (such as `fetch`), but includes resources referenced in HTML and even the initial request to `index.html` itself. Service Worker-based caching is thus completely programmable, and doesn't rely on server-specified caching headers. | |
Unlike the other scripts which make up an application (such as the Angular app bundle), the Service Worker is preserved after the user closes the tab. T |
