Automate your requests using Postman Collections – Part #2.

March 30, 2018July 20, 2018Studio-Scala

Reading Time: 4 minutes Previously on the blog, We discussed what is Postman Collection and how to create them. But our main aim is to use these collections to automate our requests, such that, we can dynamically modify: URLs Paths Request parameters And a lot more. As we referred in the earlier blog, We first need to understand the reasons for these automations. Environments: While working with APIs we Continue Reading

Automate your requests using Postman Collections – Part #1.

March 30, 2018July 20, 2018Studio-Scala

Reading Time: 3 minutes We usually use the Postman to send requests to our APIs and get a response. All the requests that we send come under history so that we could re-use the requests. But this is a manual approach. So the questions that rises are: Why use Postman collections?. Why would we need to automate them? We will be going through the answer to the first question Continue Reading

Actor Model : Basics before going deep.

January 31, 2018July 20, 2018Studio-Scala

Reading Time: 4 minutes We have CPUs and they are getting better every day, in helping us process fast. But CPUs are not getting faster!! What’s happening is that we now have multiple cores on them. And, to take advantage of this, we need a way to run our code concurrently. Some concurrency models that we are already familiar with, are: Processes Threads Futures Coroutines For concurrency, we as Continue Reading

Reading Time: 4 minutes What is Lagom? Lagom is not in disguise anymore. Everyone who’s following on micro-service architecture knows about Lagom framework. Lagom is an open source framework built with the shifting from monoliths to micro-services-driven application architecture in mind. It abstracts the complexity of building, running and monitoring micro-services driven applications. The Lagom framework includes Java and Scala APIs to simplify development of microservices. Lagom helps us Continue Reading
