It guarantees CloudFormation receives a response even when exceptions occur, catches Lambda timeouts, and provides structured JSON logging with request and stack IDs for tracing. The library supports long-running operations via polling, which re-invokes the Lambda function every 2 minutes until completion, bypassing the 15-minute Lambda timeout limit.\n\nYou use it by decorating handler functions for create, update, and delete lifecycle events, then calling the helper instance in your main handler. It manages response formatting, error propagation to CloudFormation stack events, and optional CloudWatch Events scheduling for polling workflows. Static typing is supported for mypy compatibility.","worth_installing":"Yes, if you are writing CloudFormation custom resources in Lambda. The library eliminates error-handling boilerplate and ensures CloudFormation receives responses reliably. However, note that maintenance is dormant (654 days since last release); verify compatibility with your Python version and current boto3/CloudFormation APIs before adopting in new projects, and monitor for any security updates."},"id":"crhelper","links":{"html":"https://skillfed.io/packages/crhelper","md":"https://skillfed.io/packages/crhelper.md","pypi":"https://pypi.org/project/crhelper/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2024-10-29","license_spdx":null,"license_treatment":"permissive","name":"crhelper","python_support":"unspecified","summary":"crhelper simplifies authoring CloudFormation Custom Resources"},"popularity":{"monthly_downloads":482836,"position":6420,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.12"}
