Effects+View+Actions(React distributed state management solution with rxjs.)
In the long process of practice, we found that the one-way data flow management application state may not be a silver bullet.so we can change the way to make React faster.
npm install --save react-eva
https://codesandbox.io/s/lr68qp453q
import React, { useState } from "react";
import ReactDOM from "react-dom";
import { useEva, createAsyncActions, createEffects } from "react-eva";
const App = ({ actions, effects }) => {
const [state, setState] = useState({ text: "default" });
const { implementActions, dispatch } = useEva({ actions, effects });
implementActions({
getText: () => state.text,
setText: text => setState({ text })
});
return (
<div className="sample">
<div className="text">{state.text}</div>
<button className="inner-btn" onClick={() => dispatch("onClick")}>
button
</button>
</div>
);
};
const actions = createAsyncActions("getText", "setText");
const effects = createEffects(async $ => {
console.log(await actions.getText());
$("onClick").subscribe(() => {
actions.setText("hello world");
});
});
ReactDOM.render(
<App actions={actions} effects={effects} />,
document.getElementById("root")
);
useEva({actions:Object,effects:Function})
It will return the following methods.
property name | description | type | params |
---|---|---|---|
implementActions | it used for batch create state actions method,and it will communicate with externally declared actions. | Function | implementAction(type : String,handler : Function) |
dispatch | It is used to dispatch custom events. | Function | dispatch(type:String,..args : any) |
subscription | It is used to perform side-effect logic.If you set autoRun to false, then you need to call it manually. | Function | subscription() |
connect(options : Object | ReactComponent) : (Target : ReactComponent)=>ReactComponent
The connect's options
property name | description | type |
---|---|---|
autoRun | It is used to auto run the subscription. | Boolean |
The target component will receive the following properties.
property name | description | type | params |
---|---|---|---|
implementActions | it used for batch create state actions method,and it will communicate with externally declared actions. | Function | implementAction(type : String,handler : Function) |
dispatch | It is used to dispatch custom events. | Function | dispatch(type:String,..args : any) |
subscription | It is used to perform side-effect logic.If you set autoRun to false, then you need to call it manually. | Function | subscription() |
subscribes | It is the core object of event communication. | Object |
The output component will receive the following properties.
property name | description | type | params |
---|---|---|---|
actions | This property is designed to internal and external communication of components. | Object | |
effects | This property is designed to handle the side effects of components. | Function | effects(callback : ($ : (type : String, filter : Function)=>Observable)=>{}) |
createActions(...type : String) : Object
It is used for batch declaration of state actions. (Note: The success of calling actions is that the component has been rendered.)
createAsyncActions(...type : String) : Object
It is used for batch declaration of state actions. (Note: All methods will return a Promise object, and we don't have to wait for the component to render completed when we call actions.)
mergeActions(...actions : Object) : Object
It is used for merge multi actions.
createEffects(callback : ($ : (type : String, filter : Function)=>Observable)=>{}) : Function
It is used to create a side-effect execution environment.
