  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

    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”)
