Abstract

Running apps without servers and browsers without screens sounds a little absurd, but it can be a surprisingly efficient way to solve certain problems. In this talk George will discuss a real-world solution—A service that creates mementos for marathoners based on their recorded activities—built on top of serverless technologies and Puppeteer—the Headless Chrome Node API—to work with the SVG DOM on-the-fly and create print-ready documents from GPS routes. The audience will get a firsthand look at how cutting-edge JavaScript technologies and language features were integrated with a preexisting legacy PHP backend and minimal casualties.

Outline

  • General introduction
  • What Puppeteer is and how to get started with it
  • Challenges in using serverless architecture and Puppeteer together
  • Overview of specific task (Strava API -> GPS routes -> print-ready maps on the fly)
  • Challenges in implementation with existing PHP legacy system
  • Additional design and workflow challenges (Working with provided pre-existing SVG templates)
  • High-Level view of how the final solution was implemented
  • How this approach compares to the legacy version
  • Why DOM manipulation on the server was chosen over client-side in this scenario
  • Future improvements and thoughts on using this stack for other applications
