omniscient-tools/index.js

A few tools to use with omniscient.js

var react = require('react')
var Promise = require('bluebird')
var omniscientComponent = require('omniscient')

// allows you to define a handler for react router
exports.handler = function(urlLoad, render) {
  if (!render) {
    render = urlLoad;
    urlLoad = null;
  }
  var cache = {};
  return React.createClass({
    displayName: 'OmniscientToolsHandler',
    statics: {
      urlLoad: urlLoad,
      cache: cache
    },
    render: function () {
      return render(cache.val);
    }
  })
}

exports.loadHandlers = function(state, oldState) {
  var loads = state.routes
    .filter(function(route) { return route.handler.urlLoad })
    .map(function(route) {
      route.handler.cache.val = null;
      return route.handler.urlLoad(state.params, state, oldState).then(function (val) {
        route.handler.cache.val = val;
      });
    });

  return Promise.all(loads)
}

// automatically use the jsx version. This is optional, just use normal omniscient
// if you prefer the other way

exports.component = function() {
  var comp = omniscientComponent.apply(null, arguments)
  return comp.jsx
}
