Lambda Powertools TypeScript is Generally Available

• powertools-lambda-typescript

  6 1,455 9.7 TypeScript

  Powertools is a developer toolkit to implement Serverless best practices and increase developer velocity.

  

Lambda Powertools TypeScript can't be used directly as an ES Modules dependency, but there is an issue open, so please consider adding your +1. For now, it's possible to get by with a require shim or via cjs tricks but it would be great to see native support for ES Modules in Lambda Powertools TypeScript.

• powertools-benchmarks

  1 0 0.0 TypeScript

My benchmarking tool will run each function 50 times aiming to achieve a 20% cold start rate. Code samples are available on GitHub.

• SurveyJS

  surveyjs.io sponsored

• winston

  51 22,045 7.9 JavaScript

  A logger for just about everything.

  

For the sake of comparison, I threw in another implementation of the function using the popular and enduring winston library. Let's see how they did.

• aws-embedded-metrics-node

  7 241 5.0 TypeScript

  Amazon CloudWatch Embedded Metric Format Client Library

  

Often when it comes to metrics, we think about CPU, latency and other operational metrics and AWS services usually provide those out of the box. This kind of thinking can be flawed when we end up having to use 3rd parties such as google analytics to infer critical business events. A simpler solution is to have the application emit a metric when a business event (say a customer signup) occurs. We have a few options for doing this: We can use aws-sdk, we can use the aws-embedded-metrics lib and now we can use Powertools Metrics. Which is the best? Let's see.

• powertools-lambda

One final thing to consider when deciding whether to adopt Lambda Powertools is what features may be in store in the future. The more mature libraries Lambda Powertools Python and Lambda Powertools Java include a number of useful utilities that we may like to see in Lambda Powertools TypeScript. The overall Lambda Powertools Roadmap doesn't tell us very much other than pending dotnet and golang libraries, but we can drill down into TypeScript-specific issues and glimpse the immediate future. It looks like stability is still the main priority, but there are some interesting items like RFC: Testing Factories for AWS Data Objects in the leftmost column.

• middy

  22 3,627 9.4 JavaScript

  🛵 The stylish Node.js middleware engine for AWS Lambda 🛵

  

So what's changed in the beta? A glance at the CHANGELOG suggests the answer is that not very much has changed in six months. Lambda Powertools TypeScript still supports class decorators, middy, and a manual API. It still covers the core capabilities of logging, metrics and tracing, and no new capabilities have been added. Outside of some bug fixes and optimization, this is still very much the library I previewed back in January.
