Please what kind of programmer would ever do this?

    if (weAreConnected === true) {
      this.setState({
        isConnected: true
      })
    } 
    else {
      this.setState({
        isConnected: false
      })
    }

That is just verbose unnecessarily:

    this.setState({ isConnected: weAreConnected });

And probably not so popular, but this:

    var color;
    if (this.state.isConnected) {
      color = 'green'
    }
    else {
      color = 'red'
    }

Would be simplified often to:

    var color = this.state.isConnected ? 'green' : 'red';
