How to use Redirect in the new react-router-dom of Reactjs

I am using the last version react-router module, named react-router-dom, that has become the default when developing web applications with React. I want to know how to make a redirection after a POST request. I have been making this code, but after the request, nothing happens. I review on the web, but all the data is about previous versions of the react router, and no with the last update.

Code:

import React, { PropTypes } from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import { Redirect } from 'react-router'
import SignUpForm from '../../register/components/SignUpForm';
import styles from './PagesStyles.css';
import axios from 'axios';
import Footer from '../../shared/components/Footer';
class SignUpPage extends React.Component {
constructor(props) {
super(props);
this.state = {
errors: {},
client: {
userclient: '',
clientname: '',
clientbusinessname: '',
password: '',
confirmPassword: ''
}
};
this.processForm = this.processForm.bind(this);
this.changeClient = this.changeClient.bind(this);
}
changeClient(event) {
const field = event.target.name;
const client = this.state.client;
client[field] = event.target.value;
this.setState({
client
});
}
async processForm(event) {
event.preventDefault();
const userclient = this.state.client.userclient;
const clientname = this.state.client.clientname;
const clientbusinessname = this.state.client.clientbusinessname;
const password = this.state.client.password;
const confirmPassword = this.state.client.confirmPassword;
const formData = { userclient, clientname, clientbusinessname, password, confirmPassword };
axios.post('/signup', formData, { headers: {'Accept': 'application/json'} })
.then((response) => {
this.setState({
errors: {}
});
<Redirect to="/"/> // Here, nothings happens
}).catch((error) => {
const errors = error.response.data.errors ? error.response.data.errors : {};
errors.summary = error.response.data.message;
this.setState({
errors
});
});
}
render() {
return (
<div className={styles.section}>
<div className={styles.container}>
<img src={require('./images/lisa_principal_bg.png')} className={styles.fullImageBackground} />
<SignUpForm
onSubmit={this.processForm}
onChange={this.changeClient}
errors={this.state.errors}
client={this.state.client}
/>
<Footer />
</div>
</div>
);
}
}
export default SignUpPage;

Answer

You have to use setState to set a property that will render the <Redirect> inside your render() method.

E.g.

class MyComponent extends React.Component {
  state = {
    redirect: false
  }

  handleSubmit () {
    axios.post(/**/)
      .then(() => this.setState({ redirect: true }));
  }

  render () {
    const { redirect } = this.state;

     if (redirect) {
       return <Redirect to='/somewhere'/>;
     }

     return <RenderYourForm/>;
}

You can also see an example in the official documentation: https://reacttraining.com/react-router/web/example/auth-workflow


That said, I would suggest you to put the API call inside a service or something. Then you could just use the history object to route programatically. This is how the integration with redux works.

But I guess you have your reasons to do it this way.
