stringify

Static method on JSON.

Converts a JavaScript value to a JavaScript Object Notation (JSON) string.

stringify(input: { value: any; replacer?: (this: any; key: string; value: any) => any; space?: string | number; prompt?: string }): Promise<string>
stringify(input: { value: any; replacer?: (string | number)[]; space?: string | number; prompt?: string }): Promise<string>

The prompt field is optional. When omitted (or set to an empty string) the wrapper falls back to the native JSON.stringify 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 });
// Convert reality into something you can hand off to another team.
await neuro.json.stringify({ value: state, replacer: null, space: 2, prompt: 'serialize an object to a JSON string' });

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

Generated promptJSON.stringify
You are simulating the JavaScript built-in `JSON.stringify`.
## Original signature(s)
  Overload 1: (value: any, replacer?: (this: any, key: string, value: any) => any, space?: string | number) => string
  Overload 2: (value: any, replacer?: (string | number)[], space?: string | number) => string
## JSDoc
Converts a JavaScript value to a JavaScript Object Notation (JSON) string.

## How to respond
- Behave EXACTLY as the original `stringify` 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.
