* Throw error if getInitialProps is defined as as instance method Omitting the static keyword happens pretty often. Therefore we should trigger a warning in devmode. Closes: #4782 * Document getInitialProps error * Add unit tests for loadGetInitialProps

getInitialProps was defined as an instance method
Why This Error Occurred
getInitialProps must be a static method in order to be called by next.js.
Possible Ways to Fix It
Use the static keyword.
export default class YourEntryComponent extends React.Component {
static getInitialProps () {
return {}
}
render () {
return 'foo'
}
}
or
const YourEntryComponent = function () {
return 'foo'
}
YourEntryComponent.getInitialProps = () => {
return {}
}
export default YourEntryComponent
