import React from 'react';

class TextInput extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      value: ''
    };
  }

  handleChange(event) {
    this.setState({ value: event.target.value });
  }

  render() {
    return (
      <input
        type="text"
        value={this.state.value}
        onChange={this.handleChange.bind(this)}
      />
    );
