I need to extend an existing Laravel application with a small but important set of new features. 1. WhatsApp slider Create a front-end component that slides in on desktop and mobile, initiates a WhatsApp chat with a pre-filled message, and generally streamlines our business process flow. Basic requirements: configurable position (left / right), custom greeting, optional appearance delay, and the ability to turn it on or off from an admin setting. 2. Toggle switches Replace several plain checkboxes with visually clear toggle switches that write/read the same boolean values in the database. The toggles must respect existing validation and policy logic, so the change stays strictly presentational. 3. Re-usable inline script Package the slider (or a trimmed variant of it) inside a single minified JS file that can be embedded on another page outside the Laravel ecosystem. When it loads, the script must call an endpoint in our app, fetch the relevant settings, and render the widget without breaking CSP. Deliverables • Fully tested Laravel code (PSR-12, PHP 8.2) • One compressed JS file (<50 KB gzip) ready for copy-paste inclusion • Short README covering installation, configurable parameters, and any third-party packages used No performance tuning or bug-fixing is expected this round—just clean, well-documented new features.
