import React, { Component } from 'react';
import PropTypes from 'prop-types';
import logo from './logo.svg';
import './App.css';

import LoginThemeGrey from '@mitchallen/react-login-theme-grey';

class App extends Component {

  constructor(props) {
    super(props);

    this.state = {
      isLoading: false,
      status: this.props.defaultStatus || 'Login',
      username: '',
      password: '',
    };

    this.handleChange = this.handleChange.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
    this.validateForm = this.validateForm.bind(this);
  }

  validateForm() {
    return this.state.username.length > 0
      && this.state.password.length > 0;
  }

  handleChange = (event) => {
    this.setState({
      [event.target.id]: event.target.value
    });
  }

  handleSubmit = async (event) => {
    event.preventDefault();
    this.setState({ 
      status: this.props.successMessage , 
      isLoading: false 
    });
  }

  render() {
    return (
      <div className="App">
        <header className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h1 className="App-title">Welcome to React</h1>
        </header>
        <p className="App-intro">
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
        <hr size="1" />
        <LoginThemeGrey
            handleChange={this.handleChange.bind(this)}
            handleSubmit={this.handleSubmit.bind(this)}
            validateForm={this.validateForm.bind(this)}
            status={this.state.status}
            isLoading={this.state.isLoading}
            username={this.state.username}
            password={this.state.password}
        />
        
        <hr size="1" />
      </div>
    );
  }
}

App.defaultProps = {

}

App.propTypes = {
  userHasAuthenticated: PropTypes.func.isRequired,
