A suite of utilities for AWS Lambda Functions that makes tracing with AWS X-Ray, structured logging and creating custom metrics asynchronously easier.
- AWS Lambda only – We optimise for AWS Lambda function environments only. Utilities might work with web frameworks and non-Lambda environments, though they are not officially supported.
- Eases the adoption of best practices – The main priority of the utilities is to facilitate best practices adoption, as defined in the AWS Well-Architected Serverless Lens; all other functionality is optional.
- Keep it lean – Additional dependencies are carefully considered for security and ease of maintenance, and prevent negatively impacting startup time.
- We strive for backwards compatibility – New features and changes should keep backwards compatibility. If a breaking change cannot be avoided, the deprecation and migration process should be clearly defined.
- We work backwards from the community – We aim to strike a balance of what would work best for 80% of customers. Emerging practices are considered and discussed via Requests for Comment (RFCs)
- Idiomatic – Utilities follow programming language idioms and language-specific best practices.
* Core utilities are Tracer, Logger and Metrics. Optional utilities may vary across languages.
- Structured logging initial implementation from aws-lambda-logging
- Powertools idea DAZN Powertools
