{"id":13333,"library":"iniparser","title":"Node INI Parser","description":"This package, `iniparser`, provides a straightforward INI file parser for Node.js environments. Its current stable version is 1.0.5, released in 2012, indicating that the project is no longer actively maintained. It focuses on synchronous and asynchronous parsing of `.ini` files, supporting basic sections and key-value pairs. As an early Node.js utility, it exclusively uses CommonJS modules and does not offer modern features like ESM compatibility, comprehensive configuration options, or built-in TypeScript definitions. Its core functionality includes parsing content from files or strings into a JavaScript object structure. Compared to more recent INI parsers like `@jedmao/ini-parser` or `npm/ini`, `iniparser` lacks ongoing development, broader INI specification support, and a robust community for bug fixes or feature enhancements. It had a brief active period but has been dormant for over a decade.","status":"abandoned","version":"1.0.5","language":"javascript","source_language":"en","source_url":"git://github.com/shockie/node-iniparser","tags":["javascript"],"install":[{"cmd":"npm install iniparser","lang":"bash","label":"npm"},{"cmd":"yarn add iniparser","lang":"bash","label":"yarn"},{"cmd":"pnpm add iniparser","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"This package only supports CommonJS (`require`).
