ECMAScript Nano Libs

This repository contains numerous small utility packages. These packages serve various useful purposes and are written in nano ESModule without any dependencies.

Here is a brief overview of the included libraries:

  1. tsconfig-base: This is a foundational TypeScript configuration used for Alwatr projects.
  2. flat-string: The flat-string function flattens the underlying C structures of a concatenated JavaScript string.
  3. global-this: This TypeScript module provides a cross-platform alternative to globalThis named globalScope. This object works across different environments, including browsers (window), Node.js (global), and Web Workers (self).
  4. platform-info: This module offers a method to identify the current platform where the script is being executed. It defines a platformInfo constant that contains details about the current platform.
  5. prettier-config: These are Alwatr's shared configurations for Prettier.
  6. eslint-config: This is Alwatr's ECMAScript Style Guide presented as shareable ESLint configurations.
  7. deep-clone: This function allows you to clone deeply nested objects and arrays in JavaScript.
  8. nano-build: This is a tool for building/bundling ECMAScript, TypeScript, and JavaScript libraries. It's user-friendly, requires no setup, follows best practices, has no dependencies, and uses esbuild for improved performance.
  9. type-helper: Collection of useful typescript type helpers.
  10. wait: Comprehensive toolkit for managing asynchronous operations.
  11. exit-hook: A utility for registering exit handlers in Node.js.
  12. flatomise: A utility for creating promises that can be externally resolved or rejected.
  13. async-queue: A queue that executes async tasks in order like mutex and semaphore methodology for javascript and typescript.
  14. node-fs: Enhanced file system operations in Node.js, including reading, writing, and handling JSON files, with both synchronous and asynchronous options.
  15. is-number: A simple utility to check if a value is a number.
  16. parse-duration: A simple utility to parse a duration string into milliseconds number.
  17. local-storage: localJsonStorage is a utility object in our TypeScript package that provides methods for interacting with the local storage in a structured and versioned manner.
  18. polyfill-has-own: A polyfill for Object.hasOwn.
  19. fetch: Enhanced fetch API with cache strategy, retry pattern, timeout, helper methods and enhanced types.
