Great library. Just memo your custom nodes properly - edge re-renders cascade faster than you'd expect.

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.

Yes. VDOM is immediate mode. DOM is retained mode. Building immediate mode on top of retained mode is cursed.

React.memo(MyFlowNodeComponent) like this?
