For the "one-store" web project, a combination of React.js for the frontend and Laravel with MongoDB for the backend will be employed. The frontend, developed with React.js, will consist of components tailored for various sections of the application such as products, tickets, and more. React Router will be utilized to facilitate navigation between different pages, and a form will be implemented to allow users to create tickets.

On the Laravel backend, the project will be set up with MongoDB as the database. Models for data entities, such as tickets and store items, will be defined, and controllers will handle CRUD operations for tickets. API endpoints will be established to enable communication between the frontend and backend.

In terms of the ticketing system, a user submitting a repair request will trigger an API call to the Laravel backend, resulting in the creation of a new ticket in the MongoDB database. A dedicated section in the React app will display all tickets, with the ability to view individual ticket details and update ticket statuses, such as marking them as "in-progress" or "completed."

For the contracting or work order system, relevant information about each ticket, including its ID, description, and status, will be stored in the MongoDB database. When generating contracts, references to tickets or direct inclusion of ticket details will be implemented. Additionally, a section of the application will be dedicated to managing contracts, allowing users to view, edit, and generate contracts related to repair tickets.

It is crucial to incorporate robust authentication and authorization mechanisms to ensure that only authorized users can create tickets or access contract-related functionalities. Comprehensive planning of the database schema, API endpoints, and user interfaces is recommended before initiating the development process.
