A cool library focusing on handling various flows

// Define custom error classes inheriting from Error
export class WorkflowError extends Error {
  public readonly workflowId?: string;
  constructor(message: string, workflowId?: string) {
    super(message);
    this.name = 'WorkflowError';
    this.workflowId = workflowId;
  }
}

export class NodeExecutionError extends WorkflowError {
  public readonly nodeId?: string;
  public readonly stepId?: string;
  constructor(message: string, nodeId?: string, stepId?: string, workflowId?: string) {
    super(message, workflowId);
    this.name = 'NodeExecutionError';
    this.nodeId = nodeId;
    this.stepId = stepId;
  }
}

export class TimeoutError extends NodeExecutionError {
   constructor(message: string, nodeId?: string, stepId?: string, workflowId?: string) {
    super(message, nodeId, stepId, workflowId);
    this.name = 'TimeoutError';
  }
}

export class AuthorizationError extends NodeExecutionError {
   constructor(message: string, nodeId?: string, stepId?: string, workflowId?: string) {
    super(message, nodeId, stepId, workflowId);
    this.name = 'AuthorizationError';
  }
}

export class ConfigurationError extends Error {
     constructor(message: string) {
        super(message);
        this.name = 'ConfigurationError';
    }
}
