vite-plugin-runtime-config

A Vite plugin (v1.0.2) enabling runtime configuration for static builds. Unlike Vite's built-in env variables that are baked at build time, this plugin allows dynamic replacement of config placeholders (e.g., {{ VITE_X }}) in index.html via a generated script (patch_runtime_config.js). Supports development mode (auto-replacement from Vite env) and production mode (post-build script execution). Requires Vite ^3.1.0 and Vitest >0.23.2 <1.0 as peer dependencies. Suitable for projects served by external webservers without SSR.
