Use

You can use Typopo as an online app, VS Code extension, or NPM package.

Online app

URL → https://typopo.org/

The online app is useful especially when you’re a book designer or a DTP operator. Before you typeset raw texts in a DTP app of your choice, run it through Typopo and fix microtypography with a single click.

VS Code extension

Installation

ES Module (Recommended)

For modern Node.js and bundler environments:

npm install typopo

import { fixTypos } from 'typopo';

CommonJS

For legacy Node.js environments or when require() is needed:

const { fixTypos } = require('typopo');

Browser/UMD

For direct browser usage without a bundler:

<script src="https://unpkg.com/typopo/dist/typopo.umd.js"></script>
<script>
  const correctedText = typopo.fixTypos('Your text here');
</script>

TypeScript Support

Typopo includes TypeScript type definitions for enhanced type safety and autocomplete:

import { fixTypos, TypopoLocale, TypopoConfiguration } from 'typopo';

// TypeScript provides autocomplete for locales
const locale: TypopoLocale = 'en-us'; // 'en-us' | 'de-de' | 'sk' | 'cs' | 'rue'

// Type-safe configuration
const config: TypopoConfiguration = {
  removeLines: true
};

// Full type checking
const result: string = fixTypos('Your text here', locale, config);

The library is written in JavaScript, but ships with type definitions for TypeScript users.

Check out the API section for usage details.

API

Fix typos in given text (string) and locale; with an optional configuration:
