Promise rings and comment zings
I made a Promise-aware debounce and throttle library for TypeScript
A tiny coding tool drops, and the comments instantly turn into a roast, a job interview, and a rename war
TLDR: A developer launched temporize, a small coding tool for handling delayed and repeated actions while still returning real results to callers. The community reaction was split between impressed users, brutal README criticism, and jokes that this is either genuinely useful or just another front-end interview favorite.
A developer showed off temporize, a small TypeScript tool kit for timing tricks like delaying, spacing out, canceling, and retrying actions. In plain English: it helps apps avoid doing the same thing too often, while still giving each caller a real promise of a result. That matters for things like search boxes, auto-save, and loading user data without everything turning into a messy pile-up. The pitch is tidy: no extra baggage, works in modern JavaScript setups, and keeps type hints intact for people who love their editor autocomplete.
But the real show was the comment section, where the mood swung wildly from praise to pure eye-roll. One of the harshest reactions came fast: “The README is slop, so I truly don’t care.” Ouch. That instantly turned the vibe from “cool new utility” into “community food fight over presentation.” Another commenter popped in with a side-eye observation that debounce is basically a front-end developer interview classic, which gave the whole launch a slight “is this useful, or just résumé-core?” energy.
Not everyone came to throw tomatoes. One fan said the library fits beautifully with automatic type-safe API tools, praising how it preserves all the helpful hints and returns while layering in these timing controls. And then, because no internet thread is complete without chaos, someone suggested renaming the whole thing to “dab.js.” Meanwhile, another commenter skipped the hype entirely and asked the question every skeptical reader was thinking: what exact real-world problem made this library necessary in the first place? In other words, the code may be polished, but the crowd still wants receipts.
Key Points
- •temporize is presented as a TypeScript timing and concurrency utility library with zero runtime dependencies and support for both ESM and CommonJS.
- •The library emphasizes promise-aware debounce and throttle behavior, where each scheduled call returns a promise for the wrapped function’s actual result.
- •The article compares temporize with lodash.debounce and lodash.throttle, listing additional features such as batching, retries, idle scheduling, async overlap control, and FIFO concurrency limiting.
- •Usage examples demonstrate `debounce`, `throttle`, and `rafThrottle`, including pending checks, flushing, cancellation, and browser/Node fallback behavior.
- •`debounceAsync` supports overlap policies of `queue`, `drop`, and `cancel-previous`, using internally supplied `AbortSignal` support for cancellation.
