Change page export validity check on client and server in development (#5857) Resolves #4055 Credit: https://github.com/zeit/next.js/pull/5095 I didn't use the ignore webpack plugin from the original PR and tested bundle size with https://github.com/zeit/next.js/pull/5339 - seems to be safe on that front. Was able to get tests to pass locally, unsure of what goes wrong in CI 🤷‍♂️ Questions 1) The initial PR didn't include changes to `next-server/lib/router` in `getRouteInfo()`. Should the same changes be made within? 2) Should we add a test for rendering a component created via `forwardRef()`? `component-with-forwardedRef`: ```javascript export default React.forwardRef((props, ref) => <span {...props} forwardedRef={ref}>This is a component with a forwarded ref</span>); ``` some test: ```javascript test('renders from forwardRef', async () => { const $ = await get$('/component-with-forwardedRef') const span = $('span') expect(span.text()).toMatch(/This is a component with a forwarded ref/) }) ``` 2018-12-17 15:09:23 +00:00			`import React from 'react'`
