I've created a middleware that checks if a request returns an invalid access response. If the status is a 401, I want to redirect the user to the login page Here's the middleware code import React from 'react'; import { push, replace } from 'react-router-redux'; const auth_check = ({ getState }) => { return (next) => (action) => { if(action.payload != undefined && action.payload.status==401){ push('login'); console.log('session expired'); } // Call the next dispatch method in the middleware chain. let returnValue = next(action); return returnValue } } export default auth_check; Including it in

I have researched on how to implement Stripe using React native, but have not found a solid way to so. Apparently, React Native does not support http module so would have to use Stripe API using fetch (as explained in http://blog.bigbinary.com/2015/11/03/using-stripe-api-in-react-native-with-fetch.html ). So my question is, is using fetch method to Stripe API endpoints a good alternative to stripe.js ? And would I be missing out on anything by not using stripe.js ?

Context: I am developing a widget-based webapp, (like the defunct iGoogle, where users can choose which widgets they want to display). Each widget is a React component. Simplified example: Here are 2 different widgets var HelloWidget = React.createClass({ render: function() { return <div>Hello {this.props.name}</div>; } }); var HiWidget = React.createClass({ render: function() { return <div>Hi {this.props.name}</div>; } }); As a user, I have chosen the HiWidget and my name is "dude" so when the system gets my preferences from the persistence layer it looks like this: var dataFromDb = { type:

I'm following the React Tutorial and got stuck on how to use React.findDOMNode . Here is my code: export class CommentForm extends React.Component<{}, {}> { handleSubmit(e: React.FormEvent) { e.preventDefault(); console.log(React.findDOMNode(this.refs['author'])); } render() { return <form className="commentForm" onSubmit={ e => this.handleSubmit(e) }> <input type="text" placeholder="Your name" ref="author" /> <input type="text" placeholder="Say something..." ref="text" /> <input type="submit" value="Post" /> </form>; } } Calling console.log(React.findDOMNode(this.refs['author'])); gives me

I'm new to React and I've made a navbar that displays the users name user <NavItem eventKey={4} href="#">{this.state.name}</NavItem> but the problem is if the user is not signed in, I get an error due to this.state.name being undefined. Is there some way I can check if this.state.name is defined before rendering it as part of the navbar or is there a better way to get rid of this error? Sure, use a ternary: render() { return ( this.state.name ? <NavItem>{this.state.name}</NavItem> : null ); } or even shorter render() { return ( this.state.name && <NavItem>{this.state.name}</NavItem> ); } Sure
