Dob
Dob is a tool for monitoring object changes. Using Proxy. Online Docs.
## Examples
There are some [demo](https://jsfiddle.net/1q772uL0/20/) on fiddle. Here's the simplest:
```typescript
import { observable, observe } from "dob";
const obj = observable({ a: 1 });
observe(() => {
console.log("obj.a has changed to", obj.a);
}); // <· obj.a has changed to 1
obj.a = 2; // <· obj.a has changed to 2
```
You can enjoy the benefits of proxy, for example `obj.a = { b: 5 }` is effective.
## Use in react component
```typescript
import { Action, observable, combineStores, inject } from "dob";
import { Connect } from "dob-react";
@observable
export class UserStore {
name = "bob";
}
export class UserAction {
@inject(UserStore) userStore: UserStore;
@Action
setName() {
this.userStore.name = "lucy";
}
}
@Connect(
combineStores({
UserStore,
UserAction
})
)
class App extends React.Component {
render() {
return (
{this.props.UserStore.name}
);
}
}
```
> Use `inject` to pick stores in action, do not `new UserStore()`, it's terrible for later maintenance.
## Use in react project
```typescript
import { Action, observable, combineStores, inject } from "dob";
import { Provider, Connect } from "dob-react";
@observable
export class UserStore {
name = "bob";
}
export class UserAction {
@inject(UserStore) userStore: UserStore;
@Action
setName() {
this.userStore.name = "lucy";
}
}
@Connect
class App extends React.Component {
render() {
return (
{this.props.UserStore.name}
);
}
}
ReactDOM.render(
,
document.getElementById("react-dom")
);
```

## Note
### Dependency injection does not support circular references
Do not allow circular dependencies between store and action, It's impossible to do like this:
```typescript
class A {
@inject(B) b;
}
class B {
@inject(A) a;
}
```
### Do not deconstruct to the last level on dynamic object
```typescript
const obj = observable({ a: 1 });
// good
obj.a = 5;
// bad
let { a } = obj;
a = 5;
```
