Thrown when trying to retrieve an async <a href='Binding-class.html'><code>Binding</code></a> using the sync API.
|
|
|
|
## Example
|
|
|
|
```javascript
|
|
var injector = Injector.resolveAndCreate([
|
|
bind(Number).toAsyncFactory(() => {
|
|
return new Promise((resolve) => resolve(1 + 2));
|
|
}),
|
|
bind(String).toFactory((v) => { return "Value: " + v; }, [String])
|
|
]);
|
|
|
|
injector.asyncGet(String).then((v) => expect(v).toBe('Value: 3'));
|
|
expect(() => {
|
|
injector.get(String);
|
|
}).toThrowError(AsycBindingError);
|
|
```
|
|
|
|
The above example throws because `String` depends on `Number` which is async. If any binding in
|
|
the dependency graph is async then the graph can only be retrieved using the `asyncGet` API.
