jsonflat

jsonflat is a lightweight Node.js library that flattens nested JSON objects to a single level using customizable delimiters.

Installation

You can install jsonflat via npm:

npm install @kishor82/jsonflat

Usage

To flata nested JSON object, import the flat function from jsonflat and use it as follows:

const { flat } = require("@kishor82/jsonflat");

const nestedObject = {
  person: {
    name: {
      first: "John",
      last: "Doe",
    },
    age: 30,
    address: {
      city: "New York",
      state: "NY",
    },
  },
};

const flattenedObject = flat(nestedObject);

console.log(flattenedObject);

The flat function accepts an optional delimiter parameter to customize the separator used in the flattened keys:

const flattenedObject = flat(nestedObject, ".");

console.log(flattenedObject);

Flattens the input JSON object to a single level.

• inputObject (Object): The nested JSON object to be flattened.
• delimiter (String): Optional. The delimiter used to separate keys in the flattened output. Default is '.'.
