Examples

• For more examples see: play.js at https://github.com/szilveszter9/smallfoot-sandbox
• Get a DOM element, read it's innerHTML, make it uppercase, and log that. (Read it from bottom to top.)

var app = l.compose(
  l.log.value,
  l.string.upper,
  l.object.getValue('innerHTML'),
  l.dom.getDomElement
);

app('#mydiv');

• Request JSON data and inject it into a template. (Read the compose from right to left.)

var userTemplate = l.template.set('<div class="avatar">{{login}}<img src="{{avatar_url}}"/></div>');
var url = "https://api.github.com/repos/mozilla/kuma/contributors";
var userTemplates = l.compose(l.map(userTemplate), l.http.getResponseJSON);
var usersTemplate = l.compose(l.array.toString, userTemplates);
var eitherUsersTemplate = l.compose(l.Either('could not generate the template'), l.array.toString, userTemplates);
function app(){
  var setMydiv = getElSetHtml('#mydiv');
  var showUsers = l.compose(l.map(setMydiv), eitherUsersTemplate);
  l.http.get(showUsers)(url)();
}

app();
