There is no hot reload for the native half and there cannot be. require()
of a .node file calls process.dlopen, Node has no matching unload, and the
live state (the winit event loop, the wgpu device, the open window, the
selection registry) lives in thread-locals of the loaded library. A second
load would get empty thread-locals and a dead window, and napi registers
the module once per process.
The rebuild is fast enough that it does not matter. Measured after
touching one file:
cargo check --lib 1.5s
cargo build --lib 4.9s
bun run build:debug (napi) ~2s
one vitest screenshot file ~2s
scripts/dev.ts watches packages/native/src, rebuilds, and refreshes a
target. A Rust edit reaches fresh PNGs in about four seconds.
bun run dev rebuild, re-render screenshots
bun scripts/dev.ts --shots diff only tests matching "diff"
bun scripts/dev.ts --app native-text rebuild, restart an example app
Screenshot mode is the default because Preview.app reloads a PNG on write
and, unlike a live window, the PNG can be read by an agent.
Builds are serialized: a burst of saves otherwise starts overlapping cargo
runs that then block on cargo's own lock and report confusing timings.
scripts/ gets its own package.json and tsconfig.json so the watcher is
type-checked (`bun x tsc -p scripts`) rather than only being run.
