Purpose

This pull request migrates the React app from Create React App (CRA) to Vite, modernizing the build system, updating dependencies, and cleaning up configuration and environment handling. The changes improve build speed, update tooling, and streamline the development workflow. Key updates include replacing CRA scripts and config files with Vite equivalents, updating environment variable usage, and cleaning up obsolete or redundant files.

These changes collectively modernize the app’s tooling and development workflow, making builds faster and the configuration more maintainable.

Does this introduce a breaking change?

Yes
No

…and configurations - Changed project structure to support Vite as the build tool. - Updated package.json to replace react-scripts with Vite and adjusted scripts accordingly. - Removed public/index.html as it is no longer needed with Vite. - Updated environment variable access from process.env to import.meta.env. - Modified TypeScript configuration to target ES2020 and updated module resolution. - Removed reportWebVitals and adjusted testing setup for Vitest. - Added Vite configuration file for server and build settings.

Pull request overview

This PR migrates the frontend from Create React App (CRA) to Vite, updating build/test tooling and switching environment variable access from process.env.REACT_APP_* to import.meta.env.VITE_*. It also updates Docker/Nginx static serving to use Vite’s dist/ output.

Changes:

Replace CRA build/test setup with Vite + Vitest (new vite.config.ts, updated tests setup, updated TS config).
Update runtime/build environment handling (VITE_* variables, import.meta.env, remove CRA-only artifacts like public/index.html and reportWebVitals).
Update container build output and static hosting path from /build to /dist.
