assertjunky

Tiny TypeScript assert library centered on scoped assert-route fallbacks.

Install

npm i assertjunky

Usage

import * as sr from 'assertjunky';

const getName = sr.fn('unknown', (value: unknown) => {
  sr.assertPlainObject(value);
  sr.assertString(value.name);
  return value.name;
});

Core ideas

• Throwing assertions with good TypeScript narrowing
• test() to convert assertion blocks into booleans
• fn() and fnAsync() to turn assert-failing branches into safe fallbacks
• A broad assert helper library without complicating the core runtime model

Build

npm run build
