all

Static method on Promise.

Creates a Promise that is resolved with an array of results when all of the provided Promises resolve, or rejected when any Promise is rejected.

all(input: { values: Iterable<T | PromiseLike<T>>; prompt?: string }): Promise<Promise<Awaited<T>[]>>
all(input: { values: T; prompt?: string }): Promise<Promise<{ -readonly [P in keyof T]: Awaited<T[P]>; }>>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native Promise.all and returns a resolved Promise without contacting the LLM. When present, the LLM is given the original arguments plus your prompt and is asked to behave like the original method.

import { configureClient, neuro } from 'neuro-ts';
configureClient({ apiKey: process.env.OPENAI_API_KEY });
// Wait-for-all. First rejection wins, hung promises hang forever. Just like cross-team dependencies.
await neuro.promise.all({ values: requests, prompt: 'resolve to an array of values when every promise fulfills, reject on first failure, hang forever if anything hangs - like waiting for all departments to sign off' });

The exact system prompt the SDK sends to your model when you provide a prompt field:

Generated promptPromise.all
You are simulating the JavaScript built-in `Promise.all`.
## Original signature(s)
  Overload 1: (values: Iterable<T | PromiseLike<T>>) => Promise<Awaited<T>[]>
  Overload 2: (values: T) => Promise<{ -readonly [P in keyof T]: Awaited<T[P]>; }>
## JSDoc
Creates a Promise that is resolved with an array of results when all of the provided Promises
resolve, or rejected when any Promise is rejected.

## How to respond
- Behave EXACTLY as the original `all` would, but use the user's intent to choose any callback / comparator / transform logic that the original would normally accept as an argument.
- Strictly preserve the original return type and shape.
- Output ONLY the JSON-encoded return value of the function call.
- Do NOT include explanations, prose, comments, or markdown fences.
- If the function would return `undefined`, output the literal string `undefined`.
- For Date / RegExp / Map / Set / TypedArray returns, output an object of the form { "__type": "Date" | "RegExp" | "Map" | "Set" | "<TypedArrayName>", ... } so the SDK can rehydrate it.
