Graduate from Preact !

(fine-grained) reactivity in pure Rust/Wasm, deleting overhead between Preact's signal system and Rust/Wasm application.

• project:

  • Implement a signal runtime
    • For example, how about porting stackblitz/alien-signals to Rust?

• server:

  • Put island attributes directly to the root node of each island
  • Memorize the relative positions of mutable parts (children(text), attributes) from the root node
    • Relative position can be encoded as a simple composition of firstChilds and nextSiblings, just pointer traversal and be very fast
  • Generate Rust/Wasm code that binds signals to mutable parts
    • No VDOM is needed, directly calls DOM API (e.g. innerText = ...)
  • Generate Rust/Wasm code that binds effects to event handlers
    • Basically, they just mutate signals. All the rest is done by the signal runtime

• client:

  • just call hydrater (Wasm code) for each island marker, via a tiny glue JS
