knockout-ssr
is a tool designed to enhance Knockout v3 applications by enabling server-side rendering (SSR) and Static Site Generation (SSG). It integrates easily into any build process and allows for gradual implementation without requiring a complete overhaul of your existing application.
While Knockout remains a simple yet powerful tool, it lags behind modern frameworks in certain features, particularly SSR. knockout-ssr
bridges this gap, offering a straightforward solution to enhance your Knockout applications. This library significantly boosts SEO and allows for asynchronous hydration, which significantly improves load speeds.
The library parses HTML documents to identify Knockout-specific binding attributes and virtual elements. It then server-renders these bindings by executing the binding values as JavaScript, utilizing the corresponding viewmodel.
Leveraging Knockout's MVVM pattern, which relies on underlying data models, knockout-ssr
allows for the creation of isomorphic viewmodels operative on both server and client sides, or distinct server-side viewmodels. Client-side, you can use applyBindings
as usual for correct view hydration. For enhanced performance, consider asynchronously executing applyBindings
to reduce JavaScript blocking and improve page load times.
