v1.1.0 · zero dependencies · fully typed

Secure strings & a 60-function
string toolkit.

Cryptographically secure generation — tokens, IDs, passphrases, secrets — plus a tree-shakeable toolkit of 60+ string utilities. One zero-dependency package for Node.js, browsers, Deno, Bun & edge.

Get Started API Reference
$ npm install @ppabari/strio
example.ts 
import { generateId, generatePassphrase } from '@ppabari/strio';
import { slugify, camelize, pluralize } from '@ppabari/strio/str';

// Cryptographically secure — bias-free Web Crypto
generateId({ prefix: 'usr' });        // → 'usr_K3xP9mQr2L4Xc'
generatePassphrase({ words: 4 });      // → 'stone-river-proud-flame'

// 60+ string utilities, tree-shakeable
slugify('Héllo, World!');           // → 'hello-world'
camelize('foo-bar_baz');            // → 'fooBarBaz'
pluralize('child');                 // → 'children'

Why strio

Batteries included, weight excluded

Everything you reach for when working with strings — secure and ergonomic, without dragging in a dependency tree.

🔐

Cryptographically secure

Tokens, IDs, passphrases & secrets from a bias-free Web-Crypto engine. Even the random* string helpers use it — never Math.random.

🧰

60+ string utilities

Manipulation, case conversion, validation, searching, formatting, padding, security & more — each a pure, tree-shakeable named export.

📦

Zero dependencies

No runtime deps. Ships ESM + CJS with complete .d.ts declarations and a tiny footprint.

🌍

Runs everywhere

Node.js ≥18, modern browsers, Deno, Bun & edge runtimes — with a built-in checkCompatibility() guard.

🌳

Tree-shakeable

Import only what you use from the /str subpath. Bundlers drop the rest — pay only for the functions you call.

⚡

Fully typed & tested

Written in strict TypeScript with 300+ tests. Great autocomplete, precise return types, and a zod integration.
