vite-plugin-custom-tsconfig

A Vite plugin (v1.0.4, latest) that lets you use custom tsconfig filenames like tsconfig.build.json or tsconfig.app.json with Vite. It works by copying your chosen tsconfig.*.json to tsconfig.json before Vite starts and removing it after the build finishes. This is a simple solution for monorepos or projects needing different TypeScript configurations for different environments. The plugin is lightweight, has no dependencies, and supports both ESM and CJS imports. Unlike alternatives like tsconfig-paths-webpack-plugin for Webpack, this plugin is Vite-specific and focuses solely on swapping tsconfig.json files.
