muneebrather/link-preview-generator repository overview

Link Preview Generator is a Node.js/TypeScript service that fetches website metadata (title, description, image, site name) from any URL. Built to demonstrate Docker multi-stage builds, reducing the final image size from approximately 1.2 GB to 246 MB

DOCKER CONCEPTS DEMONSTRATED:

• Multi-stage Dockerfile (build vs runtime separation)
• Image size optimization (~1.2GB → ~246MB)
• Production-only dependencies
• .dockerignore best practices
• TypeScript compilation inside container

TECH STACK:

• Node.js 20
• TypeScript
• Express
• link-preview-js
• Docker

⁠

USAGE:

⁠Run the container:

docker run -d \
  --name preview \
  -p 3000:3000 \
  muneebrather/link-preview:latest
