Introduction In previous posts on this topic, we learned how JMeter can help us in performance testing our applications. I am using .NET Core for the demos, but you can use APIs written in totally different languages as well. In this post, we will learn various other JMeter components and configurations and will also see … Read more
Introduction In the previous post on this topic, we’ve setup a simple JMeter performance test which is making HTTP Calls to a .NET Core API Endpoint. The test we performed, was making calls to an unauthorized API Endpoint. Today, we will see how to make HTTP calls to an endpoint which is protected by JWT … Read more
Introduction In previous post about performance testing, we learned the basics of performance testing and JMeter tool. We learned that “performance testing tests how an application or resource performs under a given load“. We also learned about performance matrices (we can measure performance in terms of): Response time Throughput (nos of requests kb/sec) Reliability (percentage … Read more
Introduction How our application is performing is a very core question in software development. In this post we will have a basic overview of performance testing, its various types and introduction of JMeter which is one of the most popular performance testing tool in industry. We will be using it to do performance testing of … Read more
Introduction In previous post, on the topic of Token Based Security, we created an API endpoint and protect it (using Authorize attribute) with IdentityServer. Then we setup a simple Angular application with an AuthService to use oidc-client library. We also created few angular components and at the end of previous post, we created two buttons … Read more
Introduction We have been discussing different parts of various Authentication/Authorization requirement scenarios. We also covered some theory and saw some demo code regarding OAUTH, OIDC, Identity Server etc. In previous post, we learned how to configure IdentityServer, AllowedScope of a client application and how to make a PasswordTokenRequest for the scopes to UserInfo Endpoint. Currently … Read more
Introduction In previous post of this series, we saw different flows to get the token from IdentityServer and then pass those token as Authorization Headers in our HTTP Calls and client application was able to get the data as expected. Today, we will continue our journey and learn more about users and claims. So, if you are new … Read more
Introduction In previous post, we learned that OAuth is an authorization framework specially built for HTTP APIs. It allows a user to securely delegate scoped API Access to an application. By scoped access means, that user define exactly what parts of an API, they want application to be allowed to use. This application can then … Read more
Introduction We all know the username/password mechanism of login to a web application. We also might have heard, used or implemented authentication/authorization systems, with or without frameworks. Token-based security is one of common mechanism to secure backend APIs. A common architecture for web applications typically consist of a web client app (e.g. an Angular or … Read more
Introduction In my previous post about Nodejs – Dependency Management, we looked at basics of what is Nodejs module. How can we use module.exports and require to work with dependencies. How folder dependencies work and why they are useful. We all look at how Nodejs lookup system works to look for dependencies and some basics … Read more
