Use Puppeteer and Nodejs to Take Screenshots and PDFs 

Did you ever thought of a simple solution to create screenshots programmatically?

As a developer I wanted to create a simple service which creates dynamic websites and have them easily sharable via screenshots and PDF. I could have created a simple NodeJS application (like described in this article) just to solve the problem at a time but thought: “Why do I not make it a simple service?”.

The basics — a simple NodeJS application spawning a puppeteer controlled headless browser to capture screenshots and images from a website — where already in place, but now I wanted to make it a bit more versatile and consumable.

What is a bit more?

• A simple and straightforward API
• Param validation
• Documentation
• Testing
• Security considerations
• Docker Images
• Simple deployment to e.g. Heroku
