So, last Saturday I visited a bookstore in Düsseldorf with my friend and we found a book named "Practical Node-Red Programming". We both were like what?!? is?!? this?!?, is this related to NodeJS or what, we've never even heard about it despite both belonging to a world of software engineering. So after coming home out of curiosity, I read about this framework and what it does, and here is everything you need to know about it. So, let's get started! 🚀

What's Node-RED?

Node-RED is like a digital playground where you can link things together using pictures instead of words. It's free software that helps connect devices, websites, and services easily.

How it works:

• Picture Connections: Instead of writing code, you drag and connect colorful circles (called nodes) to do different tasks.

• Easy to Learn: Because it's visual, it's simpler for many people to understand and use, even if they're not expert programmers.

• Helpful Community: Lots of people use Node-RED, so there are many ready-made parts (nodes) you can use, and folks ready to help if you get stuck.

What People Do with It:

• Smart Gadgets: It's used for making smart gadgets at home or work, like turning lights on and off automatically.

• Testing Ideas: People use it to try out new ideas quickly without writing lots of complicated code.

• Connecting Everything: You can link different things like your phone, computer, and even coffee machines to work together.

Where It Goes:

• You can use Node-RED on computers, tiny devices like Raspberry Pi, or even in big systems on the internet.

• It's good for small projects at home or big things in companies—it's quite flexible that way.

So, the conclusion I would say is that Node-RED is like a colorful way to connect stuff together. It's handy for making gadgets smarter, trying out new ideas, and getting different things to work as a team. Plus, lots of people use it, so there's always help around if you need it!
