@thi.ng/api

What is @thi.ng/api?

@thi.ng/api is a collection of TypeScript interfaces, types, and utility functions for functional programming, event handling, and other common tasks in JavaScript/TypeScript projects.

What are @thi.ng/api's main functionalities?

Event Handling

This feature allows you to create and manage custom events. The code sample demonstrates creating an event, adding a listener, and dispatching the event.

const { Event } = require('@thi.ng/api');

const event = new Event('test');
event.addListener('test', (e) => console.log('Event received:', e));
event.dispatch('test', { message: 'Hello, World!' });

Functional Programming Utilities

This feature provides utility functions for functional programming. The code sample demonstrates filtering an array to get even numbers and then mapping the array to get their squares.

const { map, filter } = require('@thi.ng/api');

const nums = [1, 2, 3, 4, 5];
const evenNums = filter((x) => x % 2 === 0, nums);
const squaredNums = map((x) => x * x, evenNums);
console.log(squaredNums); // [4, 16]

Type Utilities

This feature includes type-checking utilities. The code sample demonstrates checking if a value is a string or a number.

const { isString, isNumber } = require('@thi.ng/api');

console.log(isString('hello')); // true
console.log(isNumber(123)); // true
console.log(isNumber('123')); // false

Other packages similar to @thi.ng/api

lodash

Lodash is a modern JavaScript utility library delivering modularity, performance, and extras. It provides similar functional programming utilities like map, filter, and type-checking functions. However, it does not focus on event handling.

rxjs

RxJS is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. It offers more advanced event handling and functional programming utilities compared to @thi.ng/api.

ramda

Ramda is a practical functional library for JavaScript programmers. It focuses on immutability and side-effect-free functions, providing utilities similar to @thi.ng/api's functional programming features.

Environment variables

The following env variables are used to control the behavior of some functions in production builds:

• UMBRELLA_ASSERTS - if set to 1 the assert function will always be enabled. By default, assert() is disabled for production builds, i.e. if process.env.NODE_ENV === "production".
• UMBRELLA_GLOBALS - if set to 1 the exposeGlobal function will always be enabled. By default, exposeGlobal() is disabled for production builds, i.e. if process.env.NODE_ENV === "production".
