React PropTypes.oneOf to specify an enum doesn't work

Question

I have a problem to specify a property of type 'enum' in react. According to the documentation here React multiple components the following snippet should work :

position : React.PropTypes.oneOf(['rightTop','rightBottom']) 

But I get the following error

ERROR in ./app/components/mqttComponents/mqttPresence.jsx Module build failed: SyntaxError:/Users/giuseppe/Projects/sw-director/app/components/mqttComponents/mqttPresence.jsx: Unexpected token (68:36) 66 |   propTypes : { 67 |     //position: React.PropTypes.string.isRequired, > 68 |     position : React.PropTypes.oneOf(['rightTop','rightBottom']),                                            ^  69 |     showMqttClientStatus : React.PropTypes.bool.isRequired,  70 |     mqtt: React.PropTypes.object  71 |   } 

I don't realise which is the error? Maybe is something related to the new ES6 syntax ?

Answer 1

With the ES6 syntax the propTypes in React should be defined as a static property. So the only difference should be in the propTypes declaration.

static propTypes = {      position : React.PropTypes.oneOf(['rightTop','rightBottom']),      showMqttClientStatus : React.PropTypes.bool.isRequired }
