Thank you
SvelteKit and Elastic Path make a perfect combination for modern high performance and interactive eCommerce experiences.
SvelteKit breaks out of traditional single-page applications (SPA) and progressive web apps (PWA) by merging them with the best techniques from server-rendered websites. This approach allows websites to seamlessly transition from server-rendered code, ideal for content rich pages requiring high SEO, to a dynamic browser-rendered application perfect for optimizing a cart and checkout experience.
SvelteKit allows developers to create scalable, high-performance eCommerce applications with minimal effort. After two years of development, SvelteKit is now production ready with a 1.0 release and is the recommended way to build Svelte applications.
SvelteKit provides the features you would expect from a modern web framework offering front-end developers the tools needed to create a fast and impressive web application. While SvelteKit lacks the large userbase of ReactJS, it offers unique features that make it stand out.
Svelte is compiled before being served to a browser. This allows Svelte to go beyond JavaScript with new code, symbols, and techniques. This code is then compiled to raw JavaScript before being deployed. The JavaScript is then lighter-weight and more performant than forcing the browser to execute both the page specific code and the framework logic.
SvelteKit has the ability to build API endpoints directly in the application. Any page names +server.js or +server.ts will be executed on the server and can return text, JSON, GraphQL or any needed data. These API endpoints are a great approach to building a back-end for front-end (BFF) in a composable commerce architecture.
SvelteKit supports multiple deployment adapters, both standard and community supported that allow the application to be deployed to edge servers on Cloudflare, Netlify, Vercel and more. Leveraging the edge provides enhanced response times and performance for any global applications that need multi-region support.
Page code can be executed on the server, client, or both depending on the requirements. Having the ability to include server-specific code takes server-side rendering (SSR) to a new level beyond the initial HTML and CSS. It also makes supporting noscript, screenreaders, and alternative devices much easier improving accessibility and reach.
Both. SvelteKit can be used to build back-end APIs and server-rendered pages, but it also sends highly optimized JavaScript code to the front-end to power best in class reactivity. This ability to seamlessly move from backend to frontend is often referred to as a transitional app.
SvelteKit and all transitional apps make an excellent choice for eCommerce. Combined with Elastic Path Composable Commerce it creates the perfect foundation for a composable commerce solution. Since ecommerce has content rich pages that benefit from the SEO and initial load time of server-rendered pages, but also highly interactive content like product builders and the checkout funnel, SvelteKit handles both of those situations well.
ReactJS is a view library whereas SvelteKit is a full framework for building Svelte applications. ReactJS is better compared to Svelte and SvelteKit is more similar to NextJS or Remix. Better is a subjective matter and it depends on your specific requirements and selection criteria. React has a larger ecosystem than Svelte, however Svelte comes with better reactivity and performance. SvelteKit and NextJS are both run by Vercel and are excellent options for frameworks.
Yes. The commerce cloud SDK works with all JavaScript frameworks and libraries. SvelteKit and Elastic Path Commerce Cloud work well in conjunction for building eCommerce applications.
Yes. SvelteKit hit 1.0 on December 14, 2022 and is production ready. Multiple large scale websites already run on SvelteKit.
Yes. It can handle basic SSR requirements, but also offers server specific code, server endpoints, and the ability to leverage edge functions for deployment.
