Going Bare - Writing the web without a framework - Cascadia PHP 2018

Going Bare - Writing the web without a framework - Cascadia PHP 2018

Talk given at Cascadia PHP 2018

If you've only ever experienced web development through a web framework, you're missing out. Have you ever been tempted to rewrite a codebase in your favorite framework? That's a smell that you need to come to this talk.

Being comfortable developing without a framework is a crucial skill to have for refactoring legacy applications. In this talk I show you how to harness the power of going "frameworkless" so you'll feel empowered to make better decisions in your next web project. Be set free from your web-framework ball and chain.

    don’t get with a framework)
  10. joind.in/talk/2e67a @SammyK #cascadiaphp18 The of going bare skill • Writing

    bootstrap & boilerplate • Choosing exact components • Use different paradigms • Use those skills on domain code (Get to know the component ecosystem) (Like singleton, et al) (Gives you more control over how components interact) (Makes you better at writing your domain code)

  14. joind.in/talk/2e67a @SammyK #cascadiaphp18 Myth #3 You’ll spend most of your

    time on boilerplate instead of on domain code
  15. joind.in/talk/2e67a @SammyK #cascadiaphp18 Myth #4 You must be an architecture

  124. joind.in/talk/2e67a @SammyK #cascadiaphp18 Why would you go bare? It’s a

    skill you can use for legacy apps
  125. joind.in/talk/2e67a @SammyK #cascadiaphp18 I’ll just rewrite this in x framework…

  126. joind.in/talk/2e67a @SammyK #cascadiaphp18 Totes samezies except routing

    it’s really not that bad No bootstrap & boilerplate code
  146. joind.in/talk/2e67a @SammyK #cascadiaphp18 Framework pros The code is …so are

    you use when going bare documentation

    contexts going bare is more pragmatic pragmatic
  150. joind.in/talk/2e67a @SammyK #cascadiaphp18 myths? Did we bust the

  151. joind.in/talk/2e67a @SammyK #cascadiaphp18 #1 You must write everything from scratch

    Nope, use components
  152. joind.in/talk/2e67a @SammyK #cascadiaphp18 #2 You’re inherently anti- framework or anti-convention

    Nope, frameworks are great for most greenfield projects
  153. joind.in/talk/2e67a @SammyK #cascadiaphp18 #3 You’ll spend most of your time

    on bootstrapping instead of on domain code It takes a little longer at first but you’ll get faster with practice
  154. joind.in/talk/2e67a @SammyK #cascadiaphp18 #4 You must be an architecture astronaut

    Going bare is more pragmatic for legacy codebases
  155. joind.in/talk/2e67a @SammyK #cascadiaphp18 #5 You like pain No, we just

    like to improve our skills
  156. joind.in/talk/2e67a @SammyK #cascadiaphp18
