aurelia-property-injection
This plugin enables the core Aurelia's DI Container to inject dependencies into class instance properties, lifting the constructor from being the dependency bearer and decoupling child classes from parent dependencies.
The implementation follows the Convention over configuration paradigm, assuming the presence of a static injectProperties
enumeration of property: Type
to satisfy dependencies. For example, having a class like this:
import {Router} from 'aurelia-router';
export class MyClass {
static injectProperties = {
router: Router
};
}
the container will produce an instance of MyClass
with the current Router
available in the router
property.
It also provides extended implementations of the core inject
and autoinject
decorators, e.g.
import {inject} from 'aurelia-property-injection';
import {Router} from 'aurelia-router';
export class MyClass {
@inject(Router)
router;
}
and for TypeScript
import {autoinject} from 'aurelia-property-injection';
export class MyClass {
@autoinject
private router: Router;
}
Installing the plugin
Install the plugin via NPM:
npm install --save aurelia-property-injection
Enabling the plugin
To enable the plugin, simply use
it in the Aurelia's main configuration of your application:
export function configure(aurelia) {
aurelia.use
.standardConfiguration()
.developmentLogging()
.plugin('aurelia-property-injection');
aurelia.start().then(() => aurelia.setRoot());
}
