installation
To install the stable version:
npm install --save-dev @qjwvtd/share-store
That's it!
import createShareStore from '@qjwvtd/share-store';
const reducers = {reducer1,reducer2,reducer3,...};
const { useStore, useProvider, getAsyncStore } = createShareStore(reducers);
//To avoid naming conflicts, alias
export const useGloblaStore = useStore;
export const useGloblaProvider = useProvider;
export const globlaAsyncStore = getAsyncStore;
//useStore,Use within components
function App(){
const [state,dispatch] = useGloblaStore();
return <div>{state}</div>;
}
//getAsyncStore,For external use, such as in encapsulated request functions or other utility functions
function asyncRequest(){
const [state,dispatch] = globlaAsyncStore();
setimeout(() => {
dispatch({type:'xxx',data: xxx});
},2000);
}
Example
project.js
const initState = {
name: '金融城项目',
desc: '关于金融城项目的描述'
};
export default function (state = initState, action) {
switch (action.type) {
case 'init_project':
state.name = action.data.name;
state.desc = action.data.desc;
break;
}
return Object.assign({}, state);
}
user.js
const initState = {
name: '',
role: ''
};
export default function (state = initState, action) {
switch (action.type) {
case 'init_user':
state.name = action.data.name;
state.role = action.data.role;
break;
}
return Object.assign({}, state);
}
store.js
import project from './project';
import user from './user';

//To avoid naming conflicts, alias
export const useGloblaStore = useStore;
export const useGloblaProvider = useProvider;
export const globlaAsyncStore = getAsyncStore;
//app.js
import {useGloblaStore,useGloblaProvider,globlaAsyncStore} from './store';
import {getUserDataApi} from './api';
function asyncRequest(params){
//anync request
const [state, dispatch] = globlaAsyncStore();

});
}
function View(){
const [state, dispatch] = useGloblaStore();
//or
const [, dispatch] = useGloblaStore();
//or
const [state] = useGloblaStore();
//async
useEffect(() => {

},[]);
return <div>{state}</div>;
}
function App(){
//useStore() cannot be used within a top-level component,
//At this time, the Provider has not injected the store into the View
return useGloblaProvider(View);
}
