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.
