@tsdi/core is Ioc container, via typescript decorator
npm install @tsdi/coreThis repo is for distribution on npm. The source for this module is in the
main repo.
@tsdi/core is Ioc container, Injector, via typescript decorator. extends @tsdi/ioc
with features:
* can load script and inject.
* get service form injector tree.
* get services form injector tree.

class decortator, use to define the class is Ioc extends module. it will auto run after registered to helper your to setup module.
2. add service resolve.
3. module inject.
Ioc
1. Register one class will auto register depdence class (must has a class decorator).
2. get Instance can auto create constructor param. (must has a class decorator or register in container).
$3
1.
@Abstract abstract class decorator.
2. @AutoRun class, method decorator, use to define the class auto run (via a method or not) after registered.
3. @AutoWried property or param decorator, use to auto wried type instance or value to the instance of one class with the decorator.
4. @Inject property or param decorator, use to auto wried type instance or value to the instance of one class with the decorator.
5. @Injectable class decortator, use to define the class. it can setting provider to some token, singleton or not.
6. @AutoWried method decorator.
7. @Param param decorator, use to auto wried type instance or value to the instance of one class with the decorator.
8. @Singleton class decortator, use to define the class is singleton.
9. @Providers Providers decorator, for class. use to add private ref service for the class.
10. @Refs Refs decorator, for class. use to define the class as a service for target.
AOP
It's a dynamic aop base on ioc.
define a Aspect class, must with decorator:
*
@Aspect Aspect decorator, define for class. use to define class as aspect. it can setting provider to some token, singleton or not.*
@Before(matchstring|RegExp) method decorator, aop Before advice decorator.*
@After(matchstring|RegExp) method decorator, aop after advice decorator.*
@Around(matchstring|RegExp) method decorator, aop around advice decorator.*
@AfterThrowing(matchstring|RegExp) method decorator, aop AfterThrowing advice decorator.*
@AfterReturning(matchstring|RegExp) method decorator, aop AfterReturning advice decorator.*
@Pointcut(matchstring|RegExp) method decorator, aop Pointcut advice decorator.

boot
DI Module manager, application bootstrap. base on AOP.*
@DIModule DIModule decorator, use to define class as DI Module.
* @Bootstrap Bootstrap decorator, use to define class as bootstrp module.
* @Boot Boot decorator, use to define class as startup service for application.
* @Message Message decorator, for class. use to define the class as message handle register in global message queue.`tsimport { DIModule, BootApplication } from '@tsdi/boot';
