Part 1: JavaScript Application Introduction

Chris Berry JavaScript, Node, Single-Page Application, Technology Snapshot, Vue Leave a Comment

Part of the Solid Foundations Learning Series
This is the introductory post to an in-depth series of articles that will tell the story of why and how a specific web application was built. In a nutshell, it is a JavaScript-based suite of single-page applications optimized for use in a microservice environment.

In this post, we will set the stage for the series and introduce the overall design and structure of this application. In future posts of this series, there will be technical discussions about certain parts of the application and there will be theory discussions for other aspects of the application.

The web application we will be talking about started its life as a simple NodeJS and Express application….

Lean Mean Vue Machine

Chris Berry JavaScript, Technology Snapshot, Vue Leave a Comment

The year is 2019 and Command Line Interfaces abound for many of the big name JavaScript frameworks such as Angular CLI, Create React App, and the Vue CLI.

But wouldn’t it be nice to go back to the days when you could just drop a simple script tag on a page and be able to run an application? Well, here is my attempt in trying to accomplish just that.

In this post, we create a working Vue.js web application with standard CRUD functionality and deploy it without any extra dependencies other than the actual application itself.

Flow: A Static Type Checker for JavaScript

Lou Mauget JavaScript, Problem Solving, React, Technology Snapshot Leave a Comment

In this post, we’ll discuss the concept of types, compare static and dynamic types, and show an unobtrusive type inference package provided by Flow.org.

Facebook developed and maintains Flow. The package provides static typing to normally late-bound JavaScript code, including React code. It provides this analysis to a JavaScript application, even if it is an existing application.  Flow operates by carrying out a static abstract syntax tree (AST) analysis of type flows at build time.

Create your own web bots in .NET with CEFSharp!

Matt Cunningham .NET, JavaScript, Programming, Tutorial Leave a Comment

Have you ever wanted to create an automated way to load, manipulate, and then act upon a web page?

Using CEFSharp (and some strategic JavaScript), you can create headless (no GUI) interfaces of Chrome’s parent browser, Chromium, and then instruct them to do pretty much anything a web browser can do.

This is a tutorial about using CEFSharp to accomplish some basic web functions with simple examples. We’ll create three automated bots that can simulate user web interaction and programmatically react to browser events using CEF and the CEFSharp library. You can follow along by copying the code provided or by downloading…

Creating A Blockchain In JavaScript

Vince Pendergrass Blockchain, JavaScript, Technology Snapshot Leave a Comment

Blockchain is all the buzz now. And for good reason! A distributed public ledger that is extremely secure through encryption?! Imagine the millions of applicable use cases. A blockchain can be created and maintained using any modern language.

For the purpose of this blog, let’s dive into a blockchain written in JavaScript. Hopefully, this doesn’t just serve as a simple code example but also gives a very basic understanding of how a blockchain actually works.

Do keep in mind this will be very simplist…
