@Debounce / @Throttle

Rate-limit method calls — debounce waits for a pause; throttle enforces a minimum interval.


Kind	Runtime
Backends	`legacy`, `stage3`
Requires `generate`	No

@Debounce

ts

import { Debounce } from 'lombok-typescript/legacy';

class SearchBox {
  @Debounce(300)
  onInput(query: string) {
    this.search(query);
  }
}

Wrapped methods expose cancel() and flush() on the function object (legacy descriptor wiring).

Options: { leading?: boolean; trailing?: boolean } (default trailing).

@Throttle

ts

import { Throttle } from 'lombok-typescript/legacy';

class ScrollHandler {
  @Throttle(100)
  onScroll(y: number) {
    this.render(y);
  }
}

Also supports cancel() and flush() on the wrapped function.

When to use

Debounce — search boxes, resize handlers, autosave after typing stops
Throttle — scroll/mousemove streams where you want periodic updates
