Beautilities

A lightweight set of handy utilities for Javascript and Typescript.

Usage

Beautilities can be used in both node and browser environments. Install it using npm:
npm install beautilities.

There are three ways to access the functions:

Top-level (Standard Import)

import { valsAreEqual, generateId, formatDate } from 'beautilities';

Just-in-time (Dynamic Import)

const { valsAreEqual } = await import('beautilities');

Kitchen Sink (Namespace Import)

import * as beut from 'beautilities'; (not recommended in production).

Types are bundled, as are .map files for help with debugging.

Overview

Javascript is awesome. It's a dynamic, powerful, and most importantly, fun language. It rules the web. And thanks to ECMAScript and Typescript, its evolution continues. It has a slew of fantastic general and specific utility libraries, like:

• Lodash
• date-fns
• Math.js
• Ramda
• spacetime

and so on.

To these we can add Beautilities: a set of very handy functions for commonplace requirements like comparing objects, merging data sets, converting casing (of a string, or every key in an n-nested object), capitalising strings, parsing and formatting dates, working with currencies, simple wait functions, generating strong IDs, and so on. This is an ultra-lightweight library that'll save you time, energy, and bytes. Beautilities is also an ever-evolving project; there are no doubt more things to add, just as in time there will be things to take away. Such is the nature of software.

Structure

Containing the following modules, Beautilities' source is arranged very simplistically:

• arrays (Manipulation and comparison for arrays.)
• objects (Manipulation and comparison for objects.)
• functions (Manipulation and comparison for functions.)
• strings (Manipulation and comparison for strings.)
• countries (Built-in data and useful functions for working with country names and codes.)
• currencies (Built-in data and useful functions for working with currencies.)
• datetime (Conversion, formatting, and parsing functions for dates and times.)
• id (Generating random IDs of defined length, using crytpo is available.)
• misc (Set of functions without an appropriate catch-all namespace.)
• typescript (Functions and types that address Typescript deficiencies.)

Everything is commented and strong-typed. Very handy is the naming convention of functions:

• Simple yet extremely revealing names. For example, it's crystal clear the functions arrsAreEqual, objToQueryString, and isDomainOrUrl, objSnakeifyKeys, and wait do. Misnomers are exhausting, and often unconsciously so.
• Prefixes for functions ~specific to data of type x. For example, all string manipulation functions begin with str, all arrays with arr, and all object functions with obj. Your code editor's intellisense will present a popup as soon as you type the prefix and you'll be able to quickly select the required function.

Popular Functions

formatDate Beautify a date object or timestamp.
formatTime Convert a date into human-readable time.
parseDate Convert a timestamp or ISO to a JS date object.
objMerge Deeply merge objects, including arrays.
valsAreEqual Check if two values are equal, with support for all data types.
strSnakeToCamel Convert snake_case string to camelCase.
strCapitalise Capitalise the first letter of a string.
countryToCode Convert a country full name to its ISO two- or three-letter code.
isObject Check if value is a key-value object.
objSnakeifyKeys Convert all keys in an object to snakeCasing.
objsAreEqual Check if two objects are equal.
objToQueryString Convert an object of parameters to a query string.
objOmitProps Omit specific properties from an object by key names.
objKeyFromVal Get a property's key name from it's value.
objFlatten Completely flatten an object, regardless of nesting.
arrsAreEqual Check if two or more arrays are equal.
arrsMerge Merge two or more arrays.
getCurrency Get useful information about a currency such as the symbol, plural name, and decimal points.
generateId Generate a strong ID. Crypto will be used if available (e.g., in Node.js).
wait A simple promise which resolves after a defined number of seconds.
isDomainOrURL Check whether a string is a domain or a URL.

Real-world Usage

Beautilities is used by several companies from a range of different domains. The growing list includes PrestoKast, MyPT, Hamperess, Didakt.io, and The Todo App.
