deep-string-to-object

A lightweight, zero-dependency utility that converts a dot-separated string chain into a deeply nested object

Features

• Dot notation to object: converts "a.b.c" into { a: { b: { c: value } } }
• DoS protection: enforces a maximum chain depth (default: 32) to prevent stack abuse
• Secure: blocks prototype pollution
• Immutable: always returns a new object
• Dual format: ships both CJS and ESM builds
• Zero dependencies

Installation

npm install deep-string-to-object

yarn add deep-string-to-object

pnpm add deep-string-to-object

Usage

ESM

import deepConvert from 'deep-string-to-object';

const result = deepConvert('server.database.host', 'localhost');
// { server: { database: { host: 'localhost' } } }

CJS

const deepConvert = require('deep-string-to-object');

const result = deepConvert('a.b.c.d.e', 12);
// { a: { b: { c: { d: { e: 12 } } } } }
