verified May 27, 2026

object-inspect is a robust JavaScript utility that provides string representations of arbitrary JavaScript objects, designed for both Node.js and browser environments. Its primary function is to serialize objects into a human-readable string, handling complex data structures like circular references, DOM elements, and various built-in types (e.g., Map, Set, WeakMap, WeakSet, BigInt, WeakRef). The current stable version is 1.13.4. While there isn't a strict release cadence, the project actively incorporates support for new JavaScript features and addresses edge cases, with recent updates adding WeakRef and BigInt support. Key differentiators include its configurable output through options like `depth`, `quoteStyle`, `maxStringLength`, `customInspect`, `indent`, and `numericSeparator`, allowing fine-grained control over the serialization process, making it a versatile alternative or complement to Node.js's built-in `util.inspect` where cross-environment compatibility or customizability is paramount.
