About
Koa is an expressive HTTP middleware framework for 
Node.js using ES2017 async functions.
Designed by the team behind Express, it offers a modular architecture, allowing developers to compose middleware functions for routing, error handling, and context management, providing fine-grained control over the request-response cycle.
Sapper is an open-source 
Svelte framework for server-rendered and client-hydrated web applications that has been deprecated in favor of its successor, SvelteKit.
It supports file-based routing with server routes and pages, both Rollup and Webpack templates, legacy browser builds, and 
TypeScript.
