Bybit Futures API Integration Using ccxt Library with Error Handling

• The ajax object defines how data is fetched from the server.
• url: Endpoint for fetching data.
• type: HTTP method (GET).
• error: Logs errors that occur during the AJAX request.
• dataSrc: Processes the server's response. It logs the data and returns records for display.

• The columns array specifies how data fields (e.g., username, points) map to table columns.

• $response->body(): This retrieves the raw response body as a string, which you can then process based on its format.

If the raw response is in the form of a query string (e.g., key1=value1&key2=value2), you can use PHP’s built-in parse_str() function to convert it into an associative array.

• Node.js installed on your machine.
• A basic understanding of JavaScript.
• An Etherscan API key (explained below).
• Familiarity with Ethers.js for blockchain interaction.

To use the Etherscan API, you’ll need to get an API key. Here’s how:

• Etherscan: Use to fetch transaction history and display it in your dApp.
• Infura: Use to allow users to send transactions or interact with smart contracts.

Etherscan and Infura serve different purposes in the Ethereum ecosystem. Etherscan is perfect for applications that need to query blockchain data, while Infura is essential for real-time interaction with the blockchain. By understanding the strengths of each, you can choose the best service for your project, or even combine them to build powerful Ethereum applications.
