Link Preview JS

link-preview-js is a JavaScript/TypeScript module designed to extract and fetch rich HTTP link information, such as title, description, images, and videos, primarily leveraging OpenGraph tags. It processes either direct URLs or text blocks containing URLs to return structured metadata. The library is currently on stable version 4.0.0 and demonstrates an active release cadence with frequent updates. A key differentiator is its explicit focus on server-side execution (Node.js >=18 environments) or specific mobile runtimes (like React Native/Cordova), strictly advising against direct client-side usage due to browser-enforced Cross-Origin Resource Sharing (CORS) policies. It also provides a utility to parse already-fetched HTML content.
