Dependency Injection library
Simple asynchronous dependency container and injector.
Define your components in functions, return them asynchronously, and inject them in other components.
No configuration file required, component definition based on anonymous functions as factories.
Inspired by requirejs, and angularjs factories.
$ npm install plugme
In this example, a function is a component to authenticate a user, and the default admin credentials are stored as value dependencies.
var Plugme = require'plugme'Plugme;var plug = ;// Set configuration valuesplugset'adminLogin' 'admin';plugset'adminPassword' 'admin';// Set the function to authenticate, using configuration values, equivalent to defineplugset'authenticate' 'adminLogin' 'adminPassword'varif login === adminLogin && password === adminPasswordcbnull true;elsecbnull false;;doneauthenticate; // The component is returned asynchronously, but a return statement can be used if synchronous;// Use the authenticate function in application code, equivalent to requireplugget'authenticate'authenticate'foo' 'bar'console.log'Is authenticated:' isAuthenticated;;authenticate'admin' 'admin'console.log'Is authenticated:' isAuthenticated;;;
"Introspection" (using .toString on a function and infer dependencies from arguments name) is not supported, since it does not support minification.
Typescript is not mandatory to use this library.
If you are familiar with requirejs, set is like define, and get is like require.
* Add a scope concept (inject values depending on the current session, request etc...). * Create multiple set methods, for values, factories, services and providers.
