speakingurl
A JavaScript library to generate URL slugs with transliteration and extensive customization options.
What is speakingurl?
SpeakingURL is a JavaScript library that generates URL slugs (also known as semantic or clean URLs) from input strings. It solves the problem of creating web-safe, readable, and SEO-friendly URLs by transliterating characters from many languages and handling symbols intelligently. It works both on the server with Node.js and in the browser without any dependencies.
Web developers and content managers who need to generate consistent, internationalized URL slugs for blogs, e-commerce sites, or any application with user-generated content requiring clean URLs.
Developers choose SpeakingURL for its extensive language support, high configurability, and zero dependencies. It offers more transliteration options and fine-grained control (like custom character mapping and title-case handling) compared to simpler slugging libraries.
Overview

Use Cases
Best For
- Generating SEO-friendly URLs from multilingual content
- Creating clean URLs for blog posts or product titles with special characters

Pros & Cons
Pros
Supports over 25 languages including Arabic, Russian, and Vietnamese, with accurate character conversion as shown in examples like German 'Äpfel & Birnen!' becoming 'aepfel-und-birnen'.
Offers fine-grained control over separators, case handling, symbol conversion, and custom maps, allowing tailored slug generation for diverse needs, such as maintaining case or adding allowed characters.
Works in both Node.js and browser environments without external libraries, reducing bundle size and simplifying deployment, as emphasized in the installation and usage sections.
Can trim slugs to a specified length without breaking words, ensuring readability and SEO benefits, demonstrated with truncate options in the examples.
Cons
Adding support for languages not in the predefined list requires manual custom mapping, which can be tedious and error-prone, limiting adaptability to new or niche languages.
The transliteration process for non-Latin scripts may introduce computational overhead compared to simpler slug libraries, potentially impacting performance in high-volume applications.
With numerous options like uric, mark, and custom maps, it can be overkill for simple use cases, leading to unnecessary setup time and complexity for developers.
