If a breaking change cannot be avoided, the deprecation and migration process should be clearly defined. New features and changes should keep backwards compatibility. We strive for backwards compatibility.Additional dependencies are carefully considered for security and ease of maintenance, and prevent negatively impacting startup time. 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. Utilities might work with web frameworks and non-Lambda environments, though they are not officially supported. We optimize for AWS Lambda function environments and supported runtimes only.

Thus, following on the heels of similar Powertools offerings for Python and Java, AWS recently announced the latest new package, AWS Lambda Powertools for Typescript, which provides a library of utilities for AWS Lambda functions running on the Node.js runtime - working with both JavaScript and TypeScript code bases - to ease the adoption of best practices such as tracing, structured logging, custom metrics and so on.

Additional benefits include mitigating deployment risks, offering more accurate production-readiness assessments and fostering more informed decisions to deploy systems and changes. Specifically, those best practices for designing and operating reliable and secure systems in the AWS cloud are provided by the AWS Well-Architected Framework and its Serverless Lens.Īdhering to those best practices can reduce the number of bugs and boilerplate code needed to be written, while also accelerating remediation and speeding up the application lifecycle into production, AWS said. The latter is for serverless computing, helping developers implement architectural best practices for using AWS Lambda functions, typically used for event-driven computing where blocks of code - functions - are executed in response to user or system-generated events. Amazon Web Services (AWS) continues to nod to Microsoft-centric developers, most recently announcing Visual Studio on Amazon EC2, along with AWS Lambda Powertools for TypeScript.
