How to use

React & React-Native Example

Here is a simple Todo application using mobx, mobx-react and parse-mobx. Please note that you can use parse-mobx in non react js frameworks such as Angular.

todo-store.js

import {observable, action, runInAction, configure} from 'mobx';
import Parse from 'parse/react-native';
import {ParseMobx} from "parse-mobx";
    
configure({enforceActions: "observed"});
    
const Todo = Parse.Object.extend('todo');
    
export class TodoStore {
    
    
    @observable todos = [];
    @observable loading = false;
    @observable newText = "";
    
    @action
    updateText(val) {
        this.newText = val;
    }
    
    
    @action
    async fetchTodos() {
        this.loading = true;
        const todos = await new Parse.Query('todo').find();
        runInAction(() => {
            this.todos = ParseMobx.toParseMobx(todos);
            this.loading = false;
        });
    }
    
    @action
    async addTodo(title = 'unknown') {
        this.loading = true;
        const newTodo = await new Todo().set('title', title).save();
        runInAction(() => {
            this.todos.push(ParseMobx.toParseMobx(newTodo));
            this.loading = false;
        });
    }
    
    @action
    updateTodo(todo, newVal) {
        todo.set('completed', newVal).save();
    }
        
    @action
    async removeTodo(todo) {
        this.loading = true;
        await todo.destroy();
        runInAction(()=>{
            ParseMobx.deleteListItem(this.todos, todo);
            this.loading = false;
        });
    }
}

TodoApp.js

we pass a new instance of our store as props to TodoApp.

import React, {Component} from "react";
import {
    Container,
    Content,
    ListItem,
    Text,
    Body,
    Right,
    List,
    Form,
    Item,
    Label,
    Input,
    } from 'native-base';
    
    import {observer} from "mobx-react";
    import {Switch} from 'react-native';
    
    @observer
    export default class Todo extends Component {
        
    componentWillMount() {
        this.props.store.fetchTodos();
    }
        
    render() {
        return (
            <Container>
                <Content>

                                    onChange={(e) => this.props.store.updateText(e.target.value)}/>

                        {/* todo List */}
                    <List>
                        {this.props.store.todos.map((todo) => (
                            <ListItem key={todo.id}>
                                <Body>

                                <Switch value={todo.get('completed')}
                                            onValueChange={(value) => todo.set('completed', value).save()}/>
                                </Right>
                            </ListItem>
                        ))}
                    </List>
                </Content>
            </Container>
        )
    }
