react-redux 4.0.6 and Meteor
See original GitHub issueI am following the Get Started Videos for Redux and I have this error Uncaught TypeError: Cannot read property 'displayName' of undefined
with this config:
"meteor": "1.3.beta4",
"redux": "3.0.5",
"react-redux": "4.0.6",
"redux-simple-router": "1.0.2"
Here is my code:
import { createStore } from 'redux'
import { Component } from 'react'
import { combineReducers } from 'redux'
import { Provider, connect } from 'react-redux'
if (Meteor.isClient) {
Meteor.startup(function () {
const todoReducer = (state, action) => {
switch (action.type){
case 'ADD_TODO':
return {
id: action.id,
text: action.text,
completed: false
};
case 'TOGGLE_TODO':
if (state.id != action.id) return state
else{
return {
...state,
completed: !state.completed
};
}
default:
return state;
}
};
const todosReducer = (state = [], action) => {
switch (action.type){
case 'ADD_TODO':
return [
...state,
todoReducer(undefined, action) // no state for a new todo
];
case 'TOGGLE_TODO':
return state.map(t => todoReducer(t, action));
default:
return state;
}
};
const visibilityFilterReducer = (state = 'SHOW_ALL', action) => {
switch(action.type){
case 'SET_VISIBILITY_FILTER':
return action.filter;
default:
return state;
}
};
const rootReducer = combineReducers({
todosReducer,
visibilityFilterReducer
});
const Link = ({
active,
children,
onClick
}) => {
if(active){
return (
<span>{children}</span>
);
}
return (
<a href="#"
onClick={(e)=>{
e.preventDefault();
onClick(active);
}}
>{children}</a>
);
};
class FilterLink extends Component{
componentDidMount(){
const {store} = this.context;
this.unsubscribe = store.subscribe(()=>
this.forceUpdate()
)
}
componentWillUnmount(){
this.unsubscribe();
}
render(){
const {store} = this.context;
const props = this.props;
const state = store.getState();
return(
<Link
active={props.filter === state.visibilityFilterReducer}
onClick={()=>
store.dispatch({
type:'SET_VISIBILITY_FILTER',
filter:props.filter
})
}
>
{props.children}
</Link>
);
}
}
FilterLink.contextTypes = {
store: React.PropTypes.object
};
const getVisibleTodos = (todos, filter)=>{
switch(filter){
case 'SHOW_ALL':
return todos;
case 'SHOW_ACTIVE':
return todos.filter(t => !t.completed);
case 'SHOW_COMPLETED':
return todos.filter(t => t.completed);
}
}
const Todo = ({
onClick,
completed,
text
}) => (
<li onClick={onClick}
style = {{
textDecoration:
completed ?
'line-through':
'none'
}}>
{text}
</li>
);
const mapStateToProps = (state) => {
return {
todos: getVisibleTodos(
state.todosReducer,
state.visibilityFilterReducer
)
}
}
const mapDispatchToProps = (dispatch) => {
return {
todos: id =>
dispatch({
type:'TOGGLE_TODO',
id
})
}
};
const VisibleTodoList = connect(
mapStateToProps,
mapDispatchToProps
)(TodoList);
const TodoList = ({
todos,
onTodoClick
}) => (
<ul>
{todos.map(todo =>
<Todo
key={todo.id}
{...todo}
onClick={() => onTodoClick(todo.id)}
></Todo>
)}
</ul>
);
const AddTodo = (props, {store}) => {
let input;
return(
<div>
<input type="text" ref={
node =>{
input = node;
}
}/>
<button onClick={() => {
store.dispatch({
type:'ADD_TODO',
id: nextTodoId++,
text: input.value
});
input.value = '';
}}>Add todo</button>
</div>
)
};
AddTodo.contextTypes = {
store: React.PropTypes.object
};
const Footer = () => (
<p>
Show:
{' '}
<FilterLink filter='SHOW_ALL'>All</FilterLink>
{' '}
<FilterLink filter='SHOW_ACTIVE'>Active</FilterLink>
{' '}
<FilterLink filter='SHOW_COMPLETED'>Completed</FilterLink>
</p>
);
let nextTodoId = 0;
const TodoApp = () => (
<div>
<AddTodo/>
<VisibleTodoList/>
<Footer/>
</div>
);
ReactDOM.render(
<Provider store={createStore(rootReducer)}>
<TodoApp/>
</Provider>,
document.getElementById('render-target')
);
});
}
I will appreciate any help on this. I don’t find any FAQ or troubleshooting section on this.

Figure it out. I forgot to declare
TodoList
BEFOREconst VisibleTodoList = connect( mapStateToProps, mapDispatchToProps )(TodoList);
Actually, I have good news for you. Looking at the
next
branch, it seems that @jimbolla has already implemented such a check, here: connectAdvanced.js#L67-L71
