This is a great library. I especially appreciate that they added a version for Svelte (with specific examples for Svelte 5).
It's very convenient how you create the graph, with nodes just being Svelte components.
Adding custom edges isn't very hard either.
If you're curious what you can do with it, I made this demo for myself https://youtu.be/aVY7ySPiSo8 (never launched it).
I used Svelte Flow to visualize AI doing research, my first project using LLMs.
This is an excellent library! I only wish it had react-native support.
I've worked on a few prototype react directed acyclical diagram libraries. jsplumb-react, react-yad, and recently @lincle.
@lincle is my most recent and first attempt at supporting react-native. I tried leveraging existing interactive libraries. I was also inspired by react-flow's minimap. It is still a prototype and needs documentation but works well. I'm realizing now the demo isn't working but the demo source should hopefully give an example of how to use it.
It's quite impressive how many layers of oopsies there are in the React api now.
The curse of being successful as a software project: more people want more from you, but you are not allowed to actually remove cruft, because too many people depend on it.
The entire concept of mitigating un-intended re-rendering by wrapping your bad abstractions in more abstractions is not a category of problem for Svelte devs nor is it inherent to the platform like some inevitably of scale.
React is bad because its foundation is a bad abstraction (v-dom) and it’s spent over decade pilling on more leaky abstractions every year, leading to where we are now — clamoring over a mountain of footguns and indirection.
I'm working on an open source tool called noodles.gl that uses this library and it's been great. The devs have been good about keeping a cadence of solid changes and keeping the community updated, and overall I'm happy to have bet on this library years ago.
I love the flexibility and the fact that there's a variety of examples for basically anything I want to accomplish with it. Great work to the team.
Hah, this pops up right after I note how it's eating good with all the AI tools that use it. Deservedly so, if you're creating node based interfaces there's no reason to hand roll with D3.
This is a well-done library that’s fun to work with. I put together a proof of concept org chart generator[0] with it a while back when working on another project. Very easy to use and well-documented.
I really appreciated that they've made their pro examples available for free for education purposes. I made use of one of those examples for my undergraduate final year project.
I’ve used this library on a couple of projects with great results. One, a drag-and-drop IaC builder and the other a GitHub Actions-like task execution graph viewer.
You can programmatically remove the watermark, either via a flag or by changing the source code.

But if you use it in a commercial project, they'll likely shame you if you don't pay - like what happened to OpenAI with Agent Builder:

Personally, I’d prefer them to use a dual license, but I understand that it would likely create unnecessary hurdles for devs who just want to try out the library.

With expo DOM components it’s easy to just use this library and expo will wrap it in a webview. Then you can easily integrate it into a RN app.
Great library. Just memo your custom nodes properly - edge re-renders cascade faster than you'd expect.

Yes. VDOM is immediate mode. DOM is retained mode. Building immediate mode on top of retained mode is cursed.
React.memo(MyFlowNodeComponent) like this?

I made https://VisualFlows.io with it - among many other AI powered canvases:

Supabase uses this for the Visual Schema Designer https://supabase.com/features/visual-schema-designer
I made a desktop UI using react flow with resizing and deletion of windows.

This is cool. Is there web component library/resources for something equivalent?

I use this library for some in browser AI stuff.

We use this for our flow builder in https://wetarseel.ai
I was tempted for a moment but I think it needs JavaScript
It's a lovely library :) I'm using it in my work on general interfaces for symbolic execution debugging.
Does React Flow still advertise itself unless you pay the developers at least $169/month?

Agree, if they're going to guilt shame companies publicly and be defensive in replies, just dual license it. Not a great look.
Just what I was looking for a project.
I am building https://www.flickspeed.ai using this library
I'm a long-time SvelteFlow user and it has never disappointed so far :).
Lots of updates this year to reach parity with React Flow.
