Dob is a tool for monitoring object changes. Using Proxy.
There are some demo on fiddle. Here's the simplest:
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.
import { Action, observable, combineStores, inject } from 'dob'
import { Provider, Connect } from 'dob-react'
@observable
export class UserStore {
name = 'bob'
}
export class UserAction {
@inject(UserStore) private UserStore: UserStore;
@Action setName () {
this.store.name = 'lucy'
}
}
@Connect
class App extends React.Component {
render() {
return (
<span onClick={this.props.UserAction.setName}>
{this.props.UserStore.name}
</span>
)
}
}
ReactDOM.render(
<Provider {
...combineStores({
UserStore,
UserAction
})
}>
<App />
</Provider>
, document.getElementById('react-dom'))
Use
inject
to pick stores in action, do notnew UserStore()
, it's terrible for later maintenance.
