Installation

StringOps is available as both a Node.js package available through NPM and as an ES6 module.

To download StringOps through NPM, use the following command:

$ npm install stringops

From here you can either require the package:

const stringops = require('stringops');

Or if you're developing in an environment that allows the use of imports, you can use:

// Webpack
import * as stringoops from 'stringops';

// Browser
import * as stringops from './path/to/stringops.js';

Or even further you can import just the methods you need:

import { ltrim, ucwords, nthIndexOf } from './path/to/stringops.js';

In the browser you can also use the unpkg script like so:

<script type="module" src="https://unpkg.com/stringops@latest/stringops.js"></script>
