BREAKING CHANGE: Previously, not returning a value would fail silently, and an application trying to inject the value owuld inject an undefined value, quite possibly leading to a TypeError. Now, the application will fail entirely, and a reason will be given. Closes #4575 Closes #9210

@ngdoc error
|
|
@name $injector:undef
|
|
@fullName Undefined Value
|
|
@description
|
|
|
|
This error results from registering a factory which does not return a value (or whose return value is undefined).
|
|
|
|
The following is an example of a factory which will throw this error upon injection:
|
|
|
|
```js
|
|
angular.module("badModule", []).
|
|
factory("badFactory", function() {
|
|
doLotsOfThings();
|
|
butDontReturnAValue();
|
|
});
|
|
```
|
|
|
|
In order to prevent the error, return a value of some sort, such as an object which exposes an API for working
|
|
with the injected object.
|
|
|
|
```js
|
|
angular.module("goodModule", []).
|
|
factory("goodFactory", function() {
|
|
doLotsOfThings();
|
|
butDontReturnAValue();
|
|
|
|
return {
|
|
doTheThing: function methodThatDoesAThing() {
|
|
}
|
|
};
|
|
});
|
|
```
