## Overview

This is a React Router employee-management application for HR staff. Users manage employee records, then associate timesheets with employees and review those timesheets in a filterable table or calendar. Route loaders read SQLite data, while form actions validate and persist create/update submissions; shared form components render the inputs. The route excerpts support the listed database and calendar interactions, but not all route implementations were sampled, so unsampled wiring is omitted.

Main entry points: [`app/routes.ts`](https://github.com/ibrahimkataya/ems-challenge-ibrahimkataya/blob/main/app/routes.ts) (Route configuration), [`app/db/getDB.ts`](https://github.com/ibrahimkataya/ems-challenge-ibrahimkataya/blob/main/app/db/getDB.ts) (SQLite access), [`app/routes/employees.$employeeId._index/route.tsx`](https://github.com/ibrahimkataya/ems-challenge-ibrahimkataya/blob/main/app/routes/employees.%24employeeId._index/route.tsx) (Edit employee), [`app/routes/employees._index/route.tsx`](https://github.com/ibrahimkataya/ems-challenge-ibrahimkataya/blob/main/app/routes/employees._index/route.tsx) (Employee list)
