Adaptation and Components @necolas
“Adaption” vs “Change”
“Adaptable” vs “Adaptive”
Adaptable systems
2013 App 2014 App 2012 App
The ability to adapt-in-time is business-critical
Complexity affects the ability to adapt
Technology type as an organising principle
HTML A B C D ... CSS A B C
D ... JS A B C D ... UNIT A B C D ... ... A B C D ...
HTML A B C D ... CSS A B C
D ... JS A B C D ... UNIT A B C D ... ... A B C D ...
HTML AD B CD D ... CSS A AB C
D ... JS A B C D ... UNIT A B C D ... ... A B AC D ...
Leaky abstractions increase complexity
<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>
<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>
<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>
/* avatar */ .avatar { } /* tweet */ .tweet
{ } .tweet .avatar { } .tweet .text {} /* user card */ .user { } .user .avatar { }
Modularity is not enough
Components as the primary unit of scale

Components are simple
Components are composable & configurable
Reduces emergent complexity
Adaptable over reusable
facebook.github.io/react Defining components with React
/** @jsx React.DOM */ var Photo = React.createClass({ render: function
() { return ( <img src={this.props.src} /> ); } });
<Photo src="photo.jpg"> </Photo>
<figure className={'photo' + this.props.size}> <span className={'crop' + this.props.crop}> <img className="img"
