Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Language Guesser

Language Guesser is a robust and efficient library for detecting the language of a given text based on statistical analysis. It's perfect for applications that need to handle multilingual user input.

Installation

Install the package using npm:

npm install @horizon-rs/language-guesser

Or with yarn:

yarn add @horizon-rs/language-guesser

Usage

Detecting a list of possible languages of a text

import { Language } from '@horizon-rs/language-guesser';

const language = new Language();
const text = 'This is a sample text in English.';
const result = language.guess(text);

console.log('Detected language:', result);
Detected languages: [
  {
    alpha3: 'eng',
    alpha2: 'en',
    language: 'English',
    score: 0.9059288537549407
  },
...
]

Detecting the best single language of a given text

import { Language } from '@horizon-rs/language-guesser';

const language = new Language();
const text = 'This is a sample text in English.';
const result = language.guessBest(text);

console.log('Detected languages:', result);
Detected languages: {
  alpha3: 'eng',
  alpha2: 'en',
  language: 'English',
  score: 0.9059288537549407
}

Specifying expected language options for detection

import { Language } from '@horizon-rs/language-guesser';

const language = new Language();
const text = 'This is a sample text in English.';
const result = language.guessBest(text, ['eng']);

console.log('Detected language:', result);
Detected language: { alpha3: 'eng', alpha2: 'en', language: 'English', score: 1 }

API

Language Class

The Language class provides methods for language detection and related operations.

constructor()

Creates a new instance of the Language class.

guess(utterance: string, allowList?: string[], limit?: number): { alpha3: string; alpha2: string; language: string; score: number }[]

Detects the language of the provided utterance. You can optionally specify an allowList of accepted languages and a limit for the number of results.

guessBest(utterance: string, allowList?: string[]): { alpha3: string; alpha2: string; language: string; score: number } | undefined

Returns the best guess for the language of the utterance. You can optionally specify an allowList of accepted languages.

addExtraSentence(locale: string, sentence: string): void

Adds an extra sentence for language analysis. This can enhance the accuracy of language detection.
