MobX + React Native:注入商店的方式 [英] MobX + React Native : way to inject stores
问题描述
我正在尝试使用MobX进行新项目。
我是在2017年5月开始的,一切都运作良好。我不得不停下来,现在我继续开发它。我不得不做一个 npm install
来管理它的工作,但是现在,我对商店有一些问题...
我依靠这个教程结构:
所以,我总结一下:
- 我从MobX使用
< Provider>
到给我所有商店到我的应用 - 然后,我使用 @inject
- 获取我想要的商店。我将它用作道具,使用
this.props.UserStore
...
但它不起作用。我依靠这个教程来构建结构: https://blog.callstack.io/write-react-native-apps-in-2017-style-with-mobx-e2dffc209fcb
也许2017年5月到今天之间有更新,这会让事情变得不同...... 2017年5月运作良好。
我认为这是一个假的错误,但我找不到哪一个...
除了<$ c $上的装饰者外,一切看起来都不错c> UserStore class: @inject(['ChatStore'])@ observer @autobind
。 @inject(['ChatStore'])@ observer
用于React组件, @autobind
可能仍然按预期工作。
如果删除它们应该有效。
I'm trying to work with MobX for a new project.
I started it on May 2017, and everything was working well. I had to stop, and now I go on developing it. I had to make an npm install
to manage making it working, but now, I have some problem with stores...
I rely on this tutorial for the structure : https://blog.callstack.io/write-react-native-apps-in-2017-style-with-mobx-e2dffc209fcb
This is my structure :
Main index.js
import { Provider } from 'mobx-react';
import Stack from './router';
import stores from './stores';
export default class App extends Component {
render() {
return (
<Provider {...stores}>
<Stack />
</Provider>
);
}
}
Index.js of my stores in ./stores/index.js
import ChatStore from './ChatStore';
import UserStore from './UserStore';
export default {
UserStore: new UserStore(),
ChatStore: new ChatStore(),
};
./stores/UserStore.js (important parts)
import { observer, inject } from 'mobx-react';
import {autobind} from 'core-decorators';
...
@inject(['ChatStore'])
@observer
@autobind
export default class UserStore {
@observable isAuthenticated = false;
@observable isConnecting = false;
@observable user = null;
@observable messages = [];
@observable hasMoreMessages = false;
@observable skip = 0;
...
login() {
const payload = {
strategy: 'local',
material_id: DeviceInfo.getManufacturer(),
password: DeviceInfo.getManufacturer()
};
return this.authenticate(payload);
}
...
Now, for components part :
Router.js
import { StackNavigator } from 'react-navigation';
import Home from './containers/Home';
const stackNavigatorConfig = {
initialRouteName: 'Home',
};
export default StackNavigator({
Home: {
screen: Home,
},
}, stackNavigatorConfig);
./containers/Home.js
import React, { Component } from 'react';
import { AsyncStorage } from 'react-native';
import { observable } from 'mobx';
import { observer, inject } from 'mobx-react';
@inject('UserStore')
@observer
export default class Home extends Component {
props: Props;
...
render() {
this.props.UserStore.login().catch(error => {
console.log('LOGIN', 'ERROR', JSON.stringify(error), error.message);
});
return {
...
}
}
And then, I get an error :
So, I sum up :
- I use
<Provider>
from MobX, to give all my stores to my app - Then, I get the Store I want in my component with @inject
- I use it as a props, using
this.props.UserStore
... But it does not work. I rely on this tutorial for the structure : https://blog.callstack.io/write-react-native-apps-in-2017-style-with-mobx-e2dffc209fcb
Maybe there was an update between May 2017 and today, that makes things different... It was working well on May 2017. I think this is a dummy error, but I can't find which one...
Everything looks good except the decorators on your UserStore
class: @inject(['ChatStore']) @observer @autobind
. @inject(['ChatStore']) @observer
is used on React components, @autobind
might still work as intended.
It should work if you remove those.
