BaseClient

Overview

• Class Definition: BaseClient is defined as a class intended to provide a template for all exchange-specific classes in cryptocurrency exchange interactions.

Constructor

• Purpose: Initializes a new instance of the BaseClient class.
• Parameters:
  • apiKey: A string representing the API key for the exchange.
  • secret: A string representing the secret key for the exchange.
• Implementation:
  • Checks if BaseClient is being instantiated directly and throws an error if so, enforcing that BaseClient is an abstract class.

Abstract Methods

These methods are declared but not implemented in BaseClient. They must be implemented in any subclass extending BaseClient.

1. handleRateLimiting(response):

   • Parameter: response, an object from the API request.
   • Purpose: Intended to handle rate limiting specific to the exchange.
   • Throws an error indicating that it must be implemented in derived classes.

2. handleError(error):

   • Parameter: error, an object from the API request.
   • Purpose: Designed to handle errors from the API response.
   • Throws an error if not implemented in derived classes.

3. signRequest(params):

   • Parameter: params, the parameters of the request that need to be signed.
   • Returns: A string representing the signed parameters.
   • Purpose: To handle exchange-specific request signing.
   • Throws an error if not implemented in derived classes.

4. apiRequest(endpoint, method, parameters, headers):

   • Parameters:
     • endpoint: The API endpoint.
     • method: The HTTP method (e.g., GET, POST).
     • parameters: The parameters for the request.
     • headers: The headers for the request.
   • Returns: A promise that resolves to the response from the exchange API.
   • Purpose: To make an API request.
   • Throws an error if not implemented in derived classes.

Exporting

• The BaseClient class is exported for use in other modules.

Summary

BaseClient class is well-structured for its intended purpose as an abstract base class.
