IoT- the Internet of things is no longer a subject that requires an introduction. With advancements in technology and their regular requirement in our daily lives, we all have heard of smart devices powered with exceptional ability. , like Alexa, Google Home are making lives convenient and simpler.
Thus, enhanced with voice assistant capabilities, IoT devices support all your personal and professional commands with internet connectivity beyond traditional devices like computers or smartphones. However, many are confused and sometimes do not understand how an IoT device works, connects, and performs.
Well, as fun as it sounds for a non-technical individual to call out Alexa and say, “Hey Alexa, tell me the recipe for pasta,” the technical heads innovate consistently to provide better experiences with IoT devices.
Thus, improving IoT capability and its development, IBM Watson developed Node-RED as a programming tool for wiring together hardware, API and online services in flawlessly new ways. Node-RED, a flow-based development tool for visual programming, provides a browser-based editor, offering convenience to wire together flows using a wide range of nodes. Node includes- pre-installed for analyzing texts, running commands, sending and receiving messages, messages from HTML, JSON, XML, queuing and dequeuing messages, and processing CSV files. It also supports the integration of MongoDB and MySql.
Node-Red is a web-based editor also provides rich text editor to create Javascript functions, and the built-in library available allows to save vital functions and templates for re-use. Also, the development tool provides flow deployment in a single click in the runtime.
Thus, offering more accessible and better IoT and industrial solutions, Node-Red is a free and open-source logic engine. Also, it is a convenient and perfect application providing a visual representation for developers through a network of black boxes (nodes). Hence, Node-Red is preferable when the Application flow can be understood without having to go through each line of code. It saves time and is also excellent support when designing or troubleshooting IoT Applications.
Furthermore, as an advantage, Node-RED offers light-weight and beneficial runtime built on Node.js, making it ideal to run at the edge of the network and also on low-cost hardware such as Raspberry Pi. It is also compatible and perfect to run in the cloud. Along with, to add new capabilities, Node provides an excellent range of palette nodes with a package repository of over 225,000 modules.
Thus, combining a little markup of HTML/CSS, with coding in Javascript and a dash of metadata provides exceptionally looking User Interface. A brilliant and worth mentioning capability.
Also, providing an online flow library and flow storage in JSON, Node-Red offers flexible and easy sharing ability with others. Node-red is an ideal development tool is browser friendly; hence, you can use with any web browser like Chrome, Safari, or Firefox too.
Therefore, as a valuable tool for developers and architects offering perfect IoT solution, Node-Red is easy to use tool allowing developers to visualize and control the workflow of data and manage a series of cause-based events. Also, the ability of Node-Red that can run anywhere with Node.js, it offers flexibility to the IoT developers for solution mapping and maintenance.
Nonetheless, at the core with Node.js development services, Node-Red is a mature and widely used development tool, used by thousands of developers worldwide as a trusted platform.
