  1. Adaptation and Components @necolas

  2. “Adaption” vs “Change”

  3. “Adaptable” vs “Adaptive”

  4. Adaptable systems

  5. 2013 App 2014 App 2012 App

  6. The ability to adapt-in-time is business-critical

  7. Complexity affects the ability to adapt

  8. Technology type as an organising principle

  9. HTML A B C D ... CSS A B C

    D ... JS A B C D ... UNIT A B C D ... ... A B C D ...

  10. HTML A B C D ... CSS A B C

    D ... JS A B C D ... UNIT A B C D ... ... A B C D ...

  11. HTML AD B CD D ... CSS A AB C

    D ... JS A B C D ... UNIT A B C D ... ... A B AC D ...

  12. Leaky abstractions increase complexity

  13. <article class="user"> <div class="avatar"> <img class="avatar-img" ...> <div class="tooltip hidden">...</div>

    </div> <button class="btn btn-follow"> <span class="btn-icon"> <span class="icn icn-follow"></span> </span> <span class= "btn-text">...</span> </button> </article>

  14. <article class="user"> <button class="btn btn-follow"> <span class="btn-icon"> <span class="icn icn-follow"></span>

    </span> <span class= "btn-text">...</span> </button> </article> <div class="avatar"> <img class="avatar-img" ...> <div class="tooltip hidden">...</div> </div>

  15. <article class="user"> <button class="btn btn-follow"> <span class="btn-icon"> <span class="icn icn-follow"></span>

    </span> <span class= "btn-text">...</span> </button> </article> <div class="avatar"> <img class="user-img avatar-img" ...> <div class="tooltip hidden">...</div> </div>

  16. /* avatar */ .avatar { } /* tweet */ .tweet

    { } .tweet .avatar { } .tweet .text {} /* user card */ .user { } .user .avatar { }

  17. Modularity is not enough

  18. Components as the primary unit of scale

  19. A HTML CSS JS UNIT ...

  20. A HTML CSS JS UNIT ... B HTML CSS JS

    UNIT ...

  21. A HTML CSS JS UNIT ... B HTML CSS JS

    UNIT ... C HTML CSS JS UNIT ...

  22. A HTML CSS JS UNIT ... B HTML CSS JS

    UNIT ... C HTML CSS JS UNIT ... D HTML CSS JS UNIT ...

  23. A HTML CSS JS UNIT ... B HTML CSS JS

    UNIT ... C HTML CSS JS UNIT ... D HTML CSS JS UNIT ... ... HTML CSS JS UNIT ...

  24. Components are simple

  25. Components are composable & configurable

  26. Reduces emergent complexity

  27. Adaptable over reusable
