Hack on MDN: Web Performance

Thursday, April 4, 2019, we're having a full day hackathon to help document performance for the greater web developer community. Participants will team up to help evangelize web performance, convincing developers #PerfMatters, and teaching them tip and tricks to ensure the web is accessible to everyone, no matter their device or bandwidth.

Hack-on-MDN: Web Performance

We're going to spend two (or three) days learning about web performance. Cement what you learned by sharing and teaching others.

In this full day hack-a-thon we'll be working to improve MDN Web Docs, the premier free resource for web developers. You can choose to work on adding performance documentation to MDN, work on improving the site's performance, or anything that you think makes sense.

Work with some of the conference speakers, some Mozilla and Google staff, and the people you just met over the preceding few days to Hack on MDN.

The day will include a lot of coding, chatting, food, and fun. The registration fee is to ensure we don't have people sign up and not attend, and helps offset the cost of food, space rental, etc.

Here are some of the topics that you might want write about (estelle came up with these):


  • What is web performance
  • HTML performance features
  • JavaScript performance best practices
  • Multimedia: Images and Video
  • Advanced CSS performance features
  • How do users perceive performance?
  • Web Performance Basics
  • Mobile performance
  • Populating the page
  • Performance bottlenecks
  • Understanding latency
  • Understanding bandwidth
  • HTTP/2 and you
  • The role of TLS in performance
  • Reading performance charts
  • Analyzing JavaScript bundles
  • Lazy-loading JavaScript with dynamic imports
  • Controlling resource delivery with resource hints

Other documentation

  • The business case for performance
  • Performance Budgets
  • Mobile performance checklist
  • Optimizing Startup Performance
  • Developer Tools Performance Features
  • Understanding Latency
  • Web performance checklist

App Performance

  • Performance fundamentals
  • Optimizing startup performance
  • Profiling with the built-in profiler
  • CSS and JavaScript animation performance

This should be a lot of fun. I know I am looking forward to learning a bunch while feeling good about giving back.
