Several fixes were applied to improve the code. First, winston.transports.Console() was added to the logger, allowing logs to be viewed in the console during development, making debugging more efficient. Next, outdated options useNewUrlParser and useUnifiedTopology were removed from mongoose.connect, as they're no longer needed in Mongoose v6+, preventing deprecation warnings. The polling frequency was adjusted from 5 to 10 seconds (setTimeout(checkNewBlocks, 10000)) to reduce API calls and avoid hitting rate limits. Error handling was improved by logging network issues (ECONNABORTED, ENOTFOUND) more clearly, and implementing a 60-second wait when API rate limits (429) are reached. Finally, the setTimeout approach was used instead of setInterval to avoid multiple overlapping timers, ensuring that new checks occur only after the previous ones finish. The updates improve performance by reducing API requests and handling rate limits effectively. Stability is ensured through better error handling and automatic retries during MongoDB disconnections. Console logs enhance development efficiency by allowing easier real-time debugging.
