Logic
On demand services
import { service, makeObservable, observable } from "ya-signals";
// AppService.ts
class AppService {
public lang: string;
constructor() {
this.lang = "ru";
makeObservable(this, {
lang: observable.ref, // immutable value
});
}
}
// Only Proxy for create class on demand in future
export const appService = service(AppService);
If you run appService.user
in your code anywhere it's get app property for on demand created service
import { observer } from "ya-signals";
import { appService } from "./AppService.ts"
// App.tsx
export const App = observer(() => {
return (
<div className="App">
<h1>App lang {appService.lang}</h1>
</div>
);
});
In rare cases when it's necessary to initialize a service without invoking any method.
service.instantiate(appService);
In rare case when it's necessary to destroy a service manually.
service.destroy(appService);
Describe component logic in OOP-style
import { hook, un } from "ya-signals";
class RecipeForm {
constructor() {
un(() => {
// destroy
})
}
}
export const useRecipeForm = hook(RecipeForm)
// Somewhere in React component
const form = useRecipeForm()
And it can be with params of course
import { hook, type SignalReadonly } from "ya-signals";
// Can be object struct with named fields
type Params = {
count: number;
text: string;
};
class LocalLogic {
constructor($params: SignalReadonly<Params>) {
console.log("constructor with params", $params.value);
$params.subscribe((params) => {
console.log("updated params", params);
});
}
}
const useLocalLogic = hook(LocalLogic);
The signal
documentation see here.
And using it somewhere inside React component function
import { useRecipeForm } from './recipe-form.ts';
function Form() {
const [count, setCount] = useState(() => 1);
const [text, setText] = useState(() => "Hello");
const logic = useLocalLogic({ count, text });
return <>
// ...
}
