Visual Programming for the Modern Web
"The world is asynchronous - don't try to force the systems we build into a synchronous framework!" - J. Paul Morisson RIP
Flyde is a visual functional reactive flow-based programming tool that can be used to build anything from CLI tools to bots and web apps built. It comes with a VSCode extension that allows you to create Flyde flows from within your editor, and integrate them into your codebase using the runtime library.
Checkout the official website at flyde.dev or the examples folder for more information
Note: Flyde is still in the early stages. Your feedback/bug report/idea/complaint is highly valuable.
Everything needed to run a Flyde file is MIT licensed. That includes:
The UI library and other parts of the toolkit are GNU AGPLv3 licensed.
In other words, using Flyde flows in your software is permitted without any limitation. However, if you use Flyde's visual editor in your own work, it must be open-sourced as well. More about GNU APGLv3 here
Is this production ready?
No. Not yet. Flyde hasn't been truly battle-tested other than some internal use cases. However, if interest and usage grow there is absolutely no reason for Flyde to stay an experimental tool. If you're using Flyde for anything that is in production / has real traffic, please let me know!
Does it replace normal coding?
No. There are many things textual coding shines at. Algorithms for example would be a nightmare to build using Flyde. However, orchestrating 3 async APIs with a bit of transformation logic using Flyde feels just natural. Flyde is built to integrate with your existing code, not replace it.
What about performance?
Flyde is not optimized yet for runtime performance, nor was benchmarked. This means it should be slower than writing regular code. Just like JS is slower than C. That's the cost of abstractions. However, there are many possible ideas to improve its performance, so it's safe to say performance will improve drastically in the future.
What languages are supported?
Why did you build this?
Spending several years drawing and reviewing software design on whiteboards caused me to start dreaming of a small "run" button on the corner of the whiteboard. Modern development consisted of a lot of "glue" code, lots of concurrencies, asynchronicity, and third-party APIs. I find it hard to believe that developers will code the same way in 10 years, and I'm sure we're ready for the next abstraction. Flyde is my attempt to make that happen, and lower the barrier for developers to write complex software, just like Assembly did to punched cards programming, and C did to Assembly.
