# @rootsher/di-resolver
## installation
```sh
$ npm install @rootsher/di-resolver
```
## example usage
* define class A:
```ts
// [A]
class A {
private value: number = 1;
method(): number {
return this.value;
}
}
```
* define class B:
```ts
// [B, { deps: [A] }]
class B {
private a: A;
constructor(a: A) {
this.a = a;
}
callAMethod(): number {
return this.a.method();
}
}
```
* define class C:
```ts
// [C, { deps: [B, A] }]
class C {
public value: number = 2;
constructor(private b: B, a: A) {}
method({ value }: { value: number }) {
this.value = value;
}
}
```
* create dependency injection container definitions:
```ts
import { Resolver } from 'typed-di-container';
const resolver = new Resolver([
[A],
[
B,
{ deps: [A] }
],
[
C,
{
deps: [B, A],
calls: [
(c: C) => c.method({ value: 15 })
]
}
]
]);
```
* simple access to instances (`resolver.get([class])`):
```ts
console.log(resolver.get(B).callAMethod()); // 1
console.log(resolver.get(C).value); // 15
```
## IDE support
```ts
// IDE will help with types ("value" property, "method" method etc.)
"resolver.get(C).[value/method]"
```
