problem5

For this problem i have created an ExpressJS server for coin management. I have added 5 API endpoints for CRUD operations.

Endpoints coins.ts

• GET /api/coins: Fetches all coins. Supports filtering by blockchain, search string, and price ranges (minPrice, maxPrice).
• GET /api/coins/:id: Fetches a single coin by its ID.
• POST /api/coins: Creates a new coin. Expects currency, blockchain, price, date, and iconFilename.
• PUT /api/coins/:id: Updates an existing coin's details.
• DELETE /api/coins/:id: Removes a coin from the database.

The coins image need to have icon in folder frontend\public\icons\coins
I wont be having a upload file form in order to avoid the complexity of file upload. We can add the icon in the folder and use the filename as the icon name. I also created a coins page to interact with the API. As you can check in the coin tab file CoinsPage.tsx
