Sapper is a web application framework built on Svelte that provides server-side rendering, file-based routing, code-splitting, and offline support. It has been deprecated in favor of its successor, SvelteKit, and receives no further bug or security fixes.
Use cases
- build a server-rendered Svelte app
- migrate a legacy Sapper project to SvelteKit
- understand how SvelteKit evolved from Sapper
- maintain an existing Sapper codebase
- compare Sapper with Next.js for Svelte apps
When to choose
- you are maintaining an existing Sapper application that cannot yet be migrated
- you need to study Sapper's architecture for historical or migration purposes
When to avoid
- starting any new project - use SvelteKit instead
- you need security fixes or bug fixes
- you want long-term community support
