The Best Testing Tools for Node.js
Testing is an essential discipline for any non-trivial software project. With a dynamic language like JavaScript, testing is an absolute necessity. This post is on the best tools currently available for Node.js, but here’s a quick look at some of the many benefits of testing. Find bugs! Guard against future bug regressions. Document the expected functionality or behavior of software. Improve the design, quality, and maintainability of software. Refactor code with confidence. In this post,...
Use PKCE with OAuth 2.0 and Spring Boot for Better Security
Browser and mobile feature enhancements move fast. Often times, these technologies move faster than security standards designed to protect them can keep up. OAuth 2.0 offers the best and most mature standard for modern applications. However, there hasn’t been an official release of this standard since 2012. Eight years is a very long time in Internet technology years! That doesn’t mean that its contributors have been sitting idly by. There is active work on the...
Communicate Between Microservices with Apache Kafka
Build a Beautiful App + Login with Angular Material
Usability is a key aspect to consider when creating a web application, and that means designing a clean, easy-to-understand user interface. Leveraging common design languages can help make that goal a reality with their recognizable components that many users will understand right away. However, unlike desktop apps where the operating system provides a set of uniform widgets, there has historically been no common design language to lean on for web app developers. That was until...
Build Reusable React Components
Who doesn’t love beer? When you drink a great beer you want to tell someone. You definitely want to be able to remind yourself of the great beers you’ve had. Enter Brewstr, a beer rating application that allows you to enter a beer you’re drinking and give it a rating. This way, you know what to get next time since there’s no way you’ll remember it later. React gives the ability to create a component...
AWS Athena as a Data Analysis Supplement
As part of a security investigation, you may be tasked with determining whether a specific API action occurred throughout your cloud deployment within some distant date range. This would normally be straightforward to determine, by using either the provided CloudTrail querying console or a Security Information and Event Management platform (SIEM) which is set to consume these logs such as Splunk or Elasticsearch. For most data analysis solutions, the amount of data ingested or stored...
Protecting a PHP API Using OAuth
REST APIs are a big part of today’s Internet. Some of the everyday use cases of REST APIs are: driving the backend of single-page Web applications/mobile applications integrating different applications to exchange data and automate workflows providing the communication channel for the different parts of a complex service-oriented architecture connecting IoT devices. REST API security is essential because an API can expose powerful, mission-critical, and outright dangerous functionality over the Internet. For example, a fintech...
Build a CRUD Application with Kotlin and React
In this tutorial, you’re going to build a client and server application using React for the frontend and Kotlin with Spring Boot for the backend. You’ll first build the app unsecured before securing it using Okta. To secure the React frontend, you’ll use OAuth 2.0 login, and for the backend, you’ll use a JSON Web Token and Spring Boot’s resource server OAuth implementation. This tutorial covers a lot of ground. It also uses a lot...
How I Learned to Love Default Implementations in C# 8.0
If you haven’t heard, C# 8.0 ships with a new feature that allows you to add default implementations to interfaces. If you’re like me, you may be thinking, “Why? Why would I want to add implementations to interfaces? Isn’t that what abstract classes are for? Doesn’t that go against everything that interfaces stand for?” My immediate reaction to this new feature was visceral and negative,, but I decided to investigate closer and… I think I...
Java REST API Showdown: Which is the Best Framework on the Market?
Developing services in Java, including REST APIs, wasn’t always easy or productive until Spring came along and changed the landscape. Many years have passed since then, and new frameworks have emerged in the community. One of these frameworks was Micronaut. It’s developed by OCI, the same company behind Grails, and their goal is to help developers create microservices and serverless applications. There is also Quarkus, another framework that gained popularity over the last year. Developed...
