Software transition in React-Router v4

How can I go to a new page after some checking with React Router V4? I have something like this:

export class WelcomeForm extends Component {

    handleSubmit = (e) => {
        e.preventDefault()

        if(this.validateForm())
            // send to '/life'

    }
    render() {
        return (
            <form className="WelcomeForm" onSubmit={this.handleSubmit}>
                <input className="minutes" type="number" value={this.state.minutes} onChange={ (e) => this.handleChanges(e, "minutes")}/>
            </form>
        )
    }
}

I would like to send the user to another route. I looked at Redirect, but it looks like it will remove the current page from the story I don't want.

You are using response-router v4 , so you need to use withRouter with your component to access the properties of the history objects, then use history.pushto dynamically change the route.

withRouter :

  Router. withRouter , , : {match, location, history}.

:

import {withRouter} from 'react-router-dom';

class WelcomeForm extends Component {

    handleSubmit = (e) => {
        e.preventDefault()
        if(this.validateForm())
            this.props.history.push("/life");
    }

    render() {
        return (
            <form className="WelcomeForm" onSubmit={this.handleSubmit}>
                <input className="minutes" type="number" value={this.state.minutes} onChange={ (e) => this.handleChanges(e, "minutes")}/>
            </form>
        )
    }
}

export default withRouter(WelcomeForm);
