dp-ioc

简单、强大的基于TypeScript的IOC库。

一、安装 [ Installation ]

- npm i dp-ioc

二、快速开始

``typescript
import { Inject, Injectable, Provider } from "dp-ioc";

//定义一个可注入类
@Injectable()
class Person {
name = "rajan"
dance() {
return this.name + " dance";
}
}


// 注入到其他类中
class ClassRoom {

@Inject(Person)
public person:Person;
}

// 使用，（通过Provider函数进行实例化 ）
let classRoom = Provider(ClassRoom);
console.log(classRoom.person.name); // rajan
console.log(classRoom.person.dance); // rajan dance

`
> 注意，使用了依赖注入的类，在应用时必须通过Provider进行实例化

三、高级用法

$3

`typescript
import { Single, Injectable } from "dp-ioc";

@Single()
@Injectable()
class Person {
name = "rajan"
dance() {
return this.name + " dance";
}
}
`

$3

`typescript
import { Single, Injectable,Inject,Provider } from "dp-ioc";

@Injectable()
class Person {
name = "rajan"
dance() {
return this.name + " dance";
}
}

@Injectable()
class ClassRoom {
name = "room 001"
@Inject(Person)
person:Person
}

class School {

@Inject(ClassRoom)
classRoom:ClassRoom;
}

let school = Provider(School);

`

> 本库支持实例化Injectable可注入对象时，传入实例化的参数

`typescript
import { Single, Injectable,Inject,Provider,Constructor } from "dp-ioc";

@Injectable()
class Person {
name = "rajan"
age = 0;

//ioc 容器实例化该类时，setPersonBasicInfo方法将会被执行
@Constructor()
setPersonBasicInfo(name:string,age:number){
this.name = name;
this.age = age;
}

dance() {
return this.name + " dance";
}

}

//注入
class ClassRoom {
name = "room 001"

@Inject(Person,["小明",18])
person:Person
}

// 实例化
let classRoom = Provider(ClassRoom);
console.log(classRoom.person.name,classRoom.person.age); // 小明 18

`

$3

`typescript
import { Single, Injectable,Inject,Provider,Constructor } from "dp-ioc";

@Injectable()
class Human {
age = 0;
name = "";
}

class Student extends Human {
dance():string{
return this.name + "dance";
}
}

class classRoom {
@Inject(Student)
public Student: Student;
}

`

> 在实际项目开发中，某些对象可能需要序列化为字符串以便存储，传输。本库支持将序列化之后的对象还原为依赖对象。

`typescript
import { Single, Injectable,Inject,Provider,Constructor } from "dp-ioc";

@Injectable()
class Person {
age = 0;
name = "";
dance():string{
return this.name + "dance";
}
}

class ClassRoom {

@Inject(Student)
public Student: Student;
}

let classRoom = Provider(ClassRoom);

let classRoomStr = JSON.stringify(classRoom); // 序列化为字符串

classRoom = Provider(ClassRoom,JSON.parse(classRoomStr)); // 反序列化为依赖对象

``
