Trek

A modern web content extraction library written in Rust, compiled to WebAssembly.

Trek removes clutter from web pages and extracts clean, readable content. It's designed as a modern alternative to Mozilla Readability with enhanced features like mobile-aware extraction and consistent HTML standardization.

Features

🦀 Written in Rust for performance and safety
🌐 Compiles to WebAssembly for browser usage
📱 Mobile-aware content extraction
🎯 Site-specific extractors for popular platforms
🔧 Configurable extraction options
📊 Content scoring algorithm
🏷️ Metadata extraction (title, author, date, etc.)

Installation

As a Rust library

[dependencies]
trek-rs = "0.1"

As a WASM/JavaScript module

npm install @officialunofficial/trek

Or with other package managers:

# Yarn
yarn add @officialunofficial/trek

# pnpm
pnpm add @officialunofficial/trek

# Bun
bun add @officialunofficial/trek

Usage

Rust

use trek_rs::{Trek, TrekOptions};

let options = TrekOptions {
    debug: false,
    url: Some("https://example.com".to_string()),
    ..Default::default()
};

let trek = Trek::new(options);
let result = trek.parse(html_content)?;

println!("Title: {}", result.metadata.title);
println!("Content: {}", result.content);

Web Playground

Trek includes an interactive web playground for testing content extraction:

# Build WASM and start the playground server
make playground

# Open http://localhost:8000/playground/ in your browser

The playground provides:

Live Extraction: Paste HTML and see extracted content instantly
Multiple Views: Switch between content, metadata, raw JSON, and debug tabs
Extraction Options: Toggle clutter removal and metadata inclusion
Example Content: Pre-loaded example to demonstrate Trek's capabilities

Playground Features

Content Tab: Shows the extracted article content with proper formatting
Metadata Tab: Displays title, author, word count, and other metadata
Raw JSON Tab: View the complete extraction response
Debug Tab: See extraction details and performance metrics

JavaScript/TypeScript

import init, { TrekWasm } from '@officialunofficial/trek';

// Initialize the WASM module
await init();

const trek = new TrekWasm({
    debug: false,
    url: 'https://example.com'
});

const result = await trek.parse(htmlContent);

console.log('Title:', result.title);
console.log('Content:', result.content);
