JSON Stringify Helpers

Utilities for stable JSON stringification and cleaning surrounding JSON garbage.

stableStringify

Creates a deterministic JSON string representation of any value with guaranteed sorted object keys.

function stableStringify(obj: unknown): string

Parameter	Type	Description
`obj`	`unknown`	The value to convert to a stable JSON string.

playground.ts

Removes leading or trailing garbage characters from strings that wrap JSON objects or arrays.

function stripJsonEdgeGarbage(str: string): string

Parameter	Type	Description
`str`	`string`	The input string containing a JSON payload with potential surrounding garbage.

string: A sanitized string containing only the JSON object or array content.

playground.ts

Stable Stringification: Uses deep recursion to sort all nested objects' keys. This is critical for hash generation, digital signatures, caching keys, or performing reliable deep equality checks.
Edge Garbage Cleanup: Scans the input string to locate the outermost boundaries ({} or []) and extracts the content between them. If no JSON structure boundaries are found, it returns the original string.
