ElaString - Fluent Immutable String Transformation

Opionated fluent string transformations; You can use this package when the input is coming from a user or any other unregulated source, and you want to use the string in a normalized and formated way.

Getting Started

npm i @hisorange/elastring
# or
yarn add @hisorange/elastring

Examples

import { Elastring } from '@hisorange/elastring';

const str = new Elastring('ORMDriver');

console.log(str.snakeCase.toString()); // orm_driver
console.log(str.pascalCase.suffix('.html').toString()); // OrmDriver.html
console.log(str.upperCase.toString()); // ORMDRIVER
console.log(`${str.pathCase.prefix('../').suffix('.js')} at!`); // ../orm/driver.js at!

Technicalities

TypeScript: Everything is written in typescript from the get go, so You can have the best DX possible :)

Normalization: Some transformer will normalize the string first, this is there to avoid the weird side effects of some format to format conversion.

Immutable: After initialization the strings are immutable, so every call will create a new instance with the expected format, this is useful behavior when a string need in multiple format but be aware this is a computation heavy solution, so it's not advised to be used a in a high performance demanding environments.

Versioning: SemVer! But be aware if there is a behavior change then it will break compatibility so the major release will be changed, currently running ~110 test to ensure consistency but there are always edge cases, so each edge case will be fixed with a major release to avoid ruining someones setup on that case.
