Postlight Parser is a JavaScript library that extracts meaningful content—article text, titles, authors, dates, lead images, and excerpts—from any web page URL. It supports custom per-site parsers built with JavaScript and CSS selectors and also runs in the browser to parse the current page.

Use cases

• extract article content from a url
• get title author and publish date from web pages
• build a reader mode like browser extension
• clean html from ads and clutter for readability
• scrape article metadata for a news aggregator
• create custom site-specific content extractors

When to choose

• you need readable article content extracted from arbitrary web pages
• you want metadata like authors, dates, and lead images from articles
• you need a node or browser library for readability-style extraction
• you want to add custom per-domain extraction rules with css selectors

When to avoid

• you need a general-purpose web crawler or full-site scraper
• you need to extract structured data from non-article pages like tables or product listings
• you need a headless browser for javascript-rendered or interactive pages
• you need a maintained actively developed solution for new edge cases
