AngularJS Question

Angular 'undefined is not a function' defining component

I had working ionic code to allow the user to input a list, which I tried to factor out into a component for re-use. But on running I get the error

undefined is not a function
in line 4 of the js. How can this be fixed?

/*jshint multistr: true */
var app = angular.module('ionicApp', ['ionic']);

bindings: {label: '@'},
template: '\
<div class="list">\
<div class="item item-button-right">\
<ion-label floating>Enter {{$ctrl.label}} below then press +</ion-label>\
<input type="text" ng-model=""></input>\
<button class="button button-assertive" ng-click="addItem()">+</button>\
<div class="item item-button-right" ng-repeat="item in items track by $index">\
<button class="button button-positive" ng-click="items.splice($index,1)">-</button>\
controller: function() {
this.items = [];
this.nameinput = {name:''};
this.addItem = function(){
var name =;
if (name!=="")

Answer Source

You mentioned that you are using Ionic v1.0.0-beta1 in your project, which i believe that this version of ionic comes bundle with angular version below 1.3.

Component, on the other hand, is a new feature available in angular 1.5 and above. This explains why you got function is undefined in line 4 app.component() method.

I would suggest you to take either one of these 2 approach to resolve your issue:
1) Convert component to directive.
2) Upgrade the ionic to v1.3.2 (latest version) which supports angular 1.5
