A framework for building Open Graph images. GitHub’s new social preview images are generated by a Node.js script that fetches data from their GraphQL API, generates an HTML version of the card and then grabs a PNG snapshot of it using Puppeteer. It takes an average of 280ms to serve an image and generates around 2 million unique images a day. Interestingly, they found that bumping the available RAM from 512MB up to 513MB had a big effect on performance, because Chromium detects devices on 512MB or less and switches some processes from parallel to sequential.
