A lightweight reactive wrapper around EventSource using RxJS, providing automatic reconnection and buffering.

export class EventSourceError extends Error {
    message;
    attempt;
    constructor(message, attempt = -1) {
        const attemptMessage = attempt > -1 ? ` - Attempt: ${attempt}` : '';
        super(`EventSource Error: ${message}${attemptMessage}`);
        this.message = message;
        this.attempt = attempt;
        this.name = 'EventSourceError';
    }
}
