Programming Visually With Node-RED: Wiring Up The Internet Of Things With Ease

BY JESUS DARIO RIVERA - FREELANCE SOFTWARE ENGINEER @ TOPTAL

Writing programs in text works, and in most cases it works well. However, the ability to express programs visually is often desirable. Being able to design the flow of information through various components of a larger system is often all that is needed. Visual programming tools are also lenient towards anyone who is new to programming and struggling to handle various concepts like variables, pointers, signals, scopes, and so on.

Node-RED is a tool for programming visually. It displays relations and functions visually, and allows the user to program without having to type a language. Node-RED is a browser-based flow editor where you can add or remove nodes and wire them together in order to make them communicate with each other.

In Node-RED, every node is one of the following two types: an inject node or a function node. Inject nodes produce a message without requiring any input and push the message to the next node connected to it. Function nodes, on the other hand, take an input and perform some work on it. With a plethora of these nodes to choose from, Node-RED makes wiring together hardware devices, APIs, and online services easier than ever.

Building the "landing" page for the Dream Keybord

BY LÁSZLÓ MONDA - FREELANCE SOFTWARE DEVELOPER @ TOPTAL


As an engineer, all I could see ahead was product development and technical challenges. However, marketing is just as important and must not be overlooked. A good landing page is a must-have.

Luckily for us, we realized that there’s a lot to do before we start our crowdfunding campaign, and an attractive site could turn this otherwise idle time to our advantage by capturing people’s attention, generating more subscribers and priming us for the campaign.

So, the development of the Ultimate Landing Page for our Ultimate keyboard began in earnest.
