strz – Very Strongly Typed String Functions

• 0️⃣ No dependencies
• 🌲 Tree shakable
• 📦 Small
• 5️⃣ Typescript 5
• 📝 Strongly typed

Why?

In projects that encourage strong typing, the standard library requires manually casting to match function parameter signatures. strz brings the power of strong typing to the standard library.

Example

import { split, suffix } from 'strz'

const str = "The quick brown fox jumps over the lazy dog"

const splitStr = split(str, " ") // splitStr is of type ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"]
const suffixed = suffix(str, "!") // suffixed is of type "The quick brown fox jumps over the lazy dog!"

Installation

npm install strz

Usage

import {
  charAt,
  toLowerCase,
  toUpperCase,
  toArray,
  slice,
  uncapitalize,
  capitalize,
  prefix,
  suffix,
  split,
  trim,
  trimStart,
  trimEnd,
  replaceAll,
  replace,
  length,
} from 'strz'

const str = "The quick brown fox jumps over the lazy dog"

// Before
const char = str.charAt(0) // char is of type string
// After
const char = charAt(str, 0) // char is of type "T"

// Before
const replaced = str.replaceAll(" ", "_" ) // replaced is of type string
// After
const replaced = replaceAll(str, " ", "_" ) // replaced is of type "The_quick_brown_fox_jumps_over_the_lazy_dog"

// And so on...
