npm install @full-pack/string-packconst { ... } = require('@full-pack/string-pack');import { ... } from '@full-pack/string-pack';Adds padding to given string.
Pads the start of a string with a specified fill string a certain number of times.
// Basic Usage padStart('hello', 'abc', 3) // abcabcabchello // Limiting total length padStart('hello', 'abc', 3, 8) // abchelloPads the end of a string with a specified fill string a certain number of times.
// Basic Usage padEnd('hello', 'abc', 3); // helloabcabcabc // Limiting total length padEnd('hello', 'abc', 3, 8); // helloabcPads a string with a specified fill string a certain number of times on both ends.
// Basic usage padBidirectional('hello', '*', {repeatCount: 2}); // '**hello**' // Limiting total length padBidirectional('world', '-', {repeatCount: 3, maxLen: 10}); // '--world---' // Controlling padding distribution padBidirectional('example', '*', {repeatCount: 2, maxLen: 10, bias: PaddingBias.START}); // '**example*'Merges an array of strings into a single string using a specified separator.
merge('-', 'apple', 'orange', 'banana'); // 'apple-orange-banana' merge(true, 'apple', 'orange'); // 'apple orange' merge(false, 'apple', 'orange', 'banana'); // 'appleorangebanana'Performs a strict comparison between two strings.
compare("hello", "hello"); // true compare("abc", "ABC"); // falsePerforms a case-insensitive loose comparison between two strings.
looseCompare("hello", "HELLO"); // true looseCompare('abc', '123'); // falseCapitalizes the first letter of a word in a string.
capitalizeInitial('hello'); // 'Hello' capitalizeInitial(':> hello'); // ':> Hello'Capitalizes the first letter of each word in a given string.
capitalizeWords('hello world'); // 'Hello World' capitalizeWords('Sphinx of black quartz:-judge my vow'); // 'Sphinx Of Black Quartz:-Judge My Vow'Converts a string to snake_case format.
snakeCase('hello WorLd'); // 'hello_world' snakeCase('from-kebab-case'); // 'from_kebab_case' snakeCase('snake Case With Numbers123', true); // 'snake_case_with_numbers_one_two_three'Converts a string to kebab-case format.
kebabCase('h3llo WoRld'); // 'h3llo-world' kebabCase('from_snake_case'); // 'from-snake-case' kebabCase('kebab Case With Numbers123', true); // 'kebab-case-with-numbers-one-two-three'Converts a string to camelCase format.
camelCase('hello WoRld'); // 'helloWorld' camelCase('Test CaSe ExamplE'); // 'testCaseExample' camelCase('camel Case With Numbers123'); // 'camelCaseWithNumbers'Converts a string to PascalCase format.
