vite-plugin-fastify

Vite plugin for Fastify with Hot Module Replacement (HMR) support. Version 1.2.6 is current; release cadence is low (occasional updates). Integrates Fastify server into Vite dev and build pipelines. Key differentiator: provides HMR for Fastify routes during development, unlike vanilla Fastify setup. Does not support WebSocket; use vite-node as workaround. Ships TypeScript declarations, ESM-only. Requires Vite and Fastify as peer dependencies.
