ng-lazy-module
Does the same things you would normally do with angular.module('...')
but in a leisurely manner.
Description
This tiny zero-overhead Angular patch provides a set of lazy.…
methods for each Angular module that reflects module's own methods but can be used after the modules have been bootstrapped.
E.g. a new directive angular.module('...').lazy.directive(...)
can be defined within existing app components and compiled then.
The exceptions are config
and run
which cannot be used to define new config/run blocks when the respective phases are over.
Install
NPM
npm install --save ng-lazy-module
Bower
bower install --save ng-lazy-module
Usage
ng-lazy-module.js
is loaded after angular.js
and before Angular modules.
Let the example speak for itself.
angular; var app = angular; app; appvalue'appService' value: '%s gets the worm'; app;
Pitfalls
Precedence
lazy.run
won't be available before run
phase and the rest of lazy methods won't be available before config
phase.
The things can become too messy and complicated when there are several lazy modules that depend on each other. Although solid promise chains may minimize the possibility of having missing dependencies and maintain app design in a good shape.
config
Lazy lazy.config
can be used to get to service providers even when config
phase is over. Existing service instances may or may not be affected with changes made to corresponding providers. And modified provider $get
property takes effect only if the service hasn't been instantiated yet.
Decoration
lazy.decorator
was introduced as well, but its usage could be justified rarely. It won't have an effect on the services which were injected into advance module components and thus, instantiated (as the example shows).
Chaining
lazy.…
methods return another lazy
object, not module
. The proper chaining syntax for lazy components is
angularlazy ;
