  8. http://idlewords.com/talks/website_obesity.htm

  9. Web pages are pretty fast by default! They only get

    slow when we add “clever” cruft

  10. on the other hand…

  11. Photos are biiiiiiiiiig!

  12. The challenge: Can I make a blazing fast, image- heavy

    web page without resorting to lots of hacks & workarounds

  13. How fast can a simple HTML document be?

  14. None
  15. None
  16. None
  17. None
  18. None

  19. Speed Index: 1613 In the fastest ~10% of all websites

  20. Optimisation #1 A truthful browser spinner

  21. https://medium.com/@kellycatchpole/10-best-dog-breeds-for-your- family-22ea2cdde78d Browser says page has finished loading LIES!!!!

  22. Don’t make the browser spinner lie. When the page says

    it’s done loading, it’s really done!

    Anything very tricky or hacky at all…

  37. Easy to build?

  38. I couuuld hand-write the HTML & CSS for this, but

    I want…

  39. • A living styleguide! • Sass! • Hot reloading! •

    Reusable components!

  40. The tooling: • React (no client side!) • Webpack +

    static-site-generator-webpack-plugin • Sass • CSS Modules

  41. React is a better back-end templating language than your favourite

    back-end templating language.
  42. None
  43. None

  44. Free?

  45. GitHub Pages + CloudFlare =

  46. GitHub Pages has pretty crappy caching settings…

  47. None

  48. But if you stick CloudFlare in front of it…

  49. Easy cache header setting!

  50. Free SSL! (well, “flexible SSL”)

  51. A static HTML page + some photos Fast Easy to

    build Free ✅ ✅ ✅
