postal.js使用

requirejs.config({
    //默认情况下模块所在目录为js/lib
    baseUrl: './',
    //当模块id前缀为app时，他便由js/app加载模块文件
    //这里设置的路径是相对与baseUrl的，不要包含.js
    paths: {
        'lodash': 'lodash',
        'postal': 'postal'
    },
    shim: {
       'postal': ['lodash']
  }
});
requirejs(['lodash','postal'],
function   (_,postal) {
  var channel = postal.channel();
    // subscribe to 'name.change' topics
    var subscription = channel.subscribe( "name.change", function( data ) {
       console.log("name.changed:"+data.name);
    } );
    // And someone publishes a name change:
    channel.publish( "name.change", { name: "Dr. Who" } );

});
