@mellkam/json v0.2.1

Utility types and validators for typesafe work with json in typescript.

Installation

npm i @mellkam/json

Usage

import { type JSONValue, isJSONValue } from "@mellkam/json";

JSON.parse("...") as JSONValue;
JSON.stringify({ ... } as JSONValue)

isJSONValue({ key: "value" }) // true
isJSONValue({ key: new Map() }) // false

In the case of cyclic objects, the validator gets into an infinite loop.
