A Quick Guide to Java on Netty
Netty is a non-blocking input/output (NIO) framework that makes it relatively simple to develop low-level network servers and clients. Netty provides an incredible amount of power for developers who need to work down on the socket level, for example when developing custom communication protocols between clients and servers. It supports SSL/TLS, has both blocking and non-blocking unified APIs, and a flexible threading model. It’s also fast and performant. Netty’s asynchronous, non-blocking I/O model is designed...
Build A Simple Web App with Node and Postgres
Node.js boasts high performance and scalability for web, mobile, or desktop applications. It is one of the fastest-growing and best-supported javascript frameworks available today, and its microservice patterns has made it a hit for modern enterprise applications. PostgreSQL has also risen in popularity, to compete with MySql. The two technologies partner well as a foundation for modern, microservices-based applications. In this post, we will build a small application that keeps track of a To-Do List...
C# WebSockets Tutorial: Build a Multiplayer Game
It might seem obvious, but HTTP is a transfer protocol for hypertext. It was designed — in 1989 — to allow clients to request and receive hypertext documents from a server. While the protocol is undoubtedly a revolutionary technology, modern web applications have evolved far beyond simply responding to client requests. Today, web applications push more processing onto a client that must accommodate multiple Javascript frameworks and libraries. There is a real need for a...
Symfony 4.3 + Vue.js: PHP Apps Made Simple
Today’s Web users are a lot more sophisticated than just a few years ago. They expect applications to be fast, secure, and work equally well on their desktops and phones. Meeting these expectations requires a great deal of work so you can provide a reliable backend and a fully dynamic frontend, while keeping the whole system secure and scalable. However, with the right set of tools, you can get started quickly and become productive in...
Kafka with Java: Build a Secure, Scalable Messaging App
Today’s users expect your app to be accessible from their computer, mobile phone, tablet, or any other device! This transition to Software as a Service (SaaS) as the norm requires developers to effectively integrate with robust tools that scale to handle thousands (or even millions) of requests every second. Apache Kafka is one of the most effective tools for handling those high throughput environments. In this tutorial, you’ll learn the basic concepts behind Apache Kafka...
ASP.NET Core 3.0 MVC Secure Authentication
On September 23rd, Microsoft announced the third major release of its .NET Core framework. This new release boasts better performance, support for Windows Desktop apps, improved support for Docker containers, and more. Naturally, I was excited to see this new release and get authentication hooked into it with Okta! I put together this tutorial to demonstrate how to quickly and securely set up user management with Okta and OIDC (OpenID Connect) in an ASP.NET Core...
Create a React Native App with Login in 10 Minutes
React Native is a mobile app development framework that allows you to use React to build native iOS and Android mobile apps. Instead of using a web view and rendering HTML and JavaScript, it converts React components to native platform components. This means you can use React Native in your existing Android and iOS projects, or you can create a whole new app from scratch. In this post, I’ll show you how to add a...
Build a Simple Microservice with C# Azure Functions
I’ve always liked microservices because they embrace small, well-encapsulated building blocks. They mitigate deployment hell by treating each component of a software system as its own product, with versions, testing, and releases. A microservice is “micro” because of the narrow scope of its functionality, not necessarily because the length of its code is very short. A microservice’s functionality, so long as it’s kept to the limited scope, can go as deep as required by the...
Use Vue and GraphQL to Build a Secure App
When you develop a new web application, you most likely split the application into two parts. The server-side provides access control and data persistence, while the client-side is mostly presentational. The two parts have to communicate, and your first idea may be to implement a REST API. However, a number of flaws have been identified with the RESTful pattern, mostly related to the flexibility and speed of the request-response pattern. At Facebook, these problems were...
Get Started with Koa.js for Node Applications
Ever since JavaScript made its giant leap from frontend to backend more than 10 years ago, Express has been the go-to library for writing server-side javascript and virtually synonymous with Node.js. It was (and in many aspects it still is) a modern and simple approach backend APIs. Declarative tree-like structure of routes, native support for middleware, asynchronous request processing and a miniature memory footprint all make Express very robust for a backend. As good as...
