[Video] Quick and Effortless Testing of Kumologica-Based Lambda From Postman. In this video, learn how to test an API flow locally from Postman or any REST client with zero effort or deep understanding needed using Kumologica 2.0.
Locally testing an AWS Lambda-based API is always bit of a painful task. This is primarily due to nature of interface and signature provided by AWS Lambda. AWS Lambda by default is not an API, as it just holds the workload execution of your API. Only when an API Gateway is attached to the Lambda will it make a complete API.
Now here is the tricky part. When developing your API implementation locally, you don't have an API Gateway so you need to test the Lambda by sending the AWS API Gateway event directly to your implementation for testing.
The other option is by running a Docker instance of API Gateway locally. If you are using SAM or serverless framework, you still need to understand the AWS event and test the API implementation more like an invocation of function rather than the popular and traditional style of invoking from a REST client like postman.
Kumologica 2.0 has introduced the capability to test the API flow locally from Postman or any REST client of your choice with zero effort or understanding of AWS triggers or API gateway events needed.
Serverless Express enables you to easily host Express.js APIs on AWS Lambda and AWS HTTP API. Here is how to get started and deliver a Serverless Express.js based API with a custom domain, free SSL certificate and much more!
Adding Code to AWS Lambda, Lambda Layers, and Lambda Extensions Using Docker. With Docker, we have three ways to add code to Lambda that isn’t directly part of our Lambda function. Try to AWS Lambda, Lambda Layers, and Lambda Extensions Using Docker.
Serverless Proxy with AWS API Gateway and AWS Lambda. We can communicate between Public and Private instance via a Serverless Proxy thanks to AWS Api Gateway and AWS Lambda. Github Webhook calls a Public API Gateway, API Gateway triggers a Lambda attached to VPC.
Micronaut is creating a buzz around cloud-native application development due to its enriched features and optimizations based out of modern Polyglot JVM.
Distributed tracing is a key aspect in the new world of serverless integration as it is one of the 3 pillars of observability i.e logs, metrics, and traces.
