try
neuro.promise.try
Section titled “neuro.promise.try”Static method on Promise. Variadic items live under args.
Takes a callback of any kind (returns or throws, synchronously or asynchronously) and wraps its result in a Promise.
Signatures
Section titled “Signatures”try(input: { callbackFn?: (...args: U) => T | PromiseLike<T>; args: U; prompt?: string }): Promise<Promise<Awaited<T>>>The prompt field is optional. When omitted (or set to an empty string)
the wrapper falls back to the native Promise.try 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.
Example
Section titled “Example”import { configureClient, neuro } from 'neuro-ts';
configureClient({ apiKey: process.env.OPENAI_API_KEY });
// Sync-to-promise bridge. Shipped in 2024. Seven years after everyone needed it.await neuro.promise.try({ callbackfn: () => syncMaybeThrows(), prompt: 'invoke callbackfn synchronously and wrap its return in a promise, turning any throw into a rejection -- the async boundary that async/await needed in 2017 and finally shipped in 2024' });System prompt
Section titled “System prompt”The exact system prompt the SDK sends to your model when you provide a
prompt field:
Promise.tryYou are simulating the JavaScript built-in `Promise.try`.
## Original signature(s)
Overload 1: (callbackFn?: (...args: U) => T | PromiseLike<T>, ...args: U) => Promise<Awaited<T>>
## JSDoc
Takes a callback of any kind (returns or throws, synchronously or asynchronously) and wraps its result
in a Promise.
## How to respond
- Behave EXACTLY as the original `try` 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.
