/**
|
|
* Motivations:
|
|
*
|
|
* - Client-side getInitialProps() wont have access to the apollo client for
|
|
* that page (because it's not shared across page bundles), so wont be able to
|
|
* reset the state, leaving all the logged in user data there :(
|
|
* - So, we have to have a shared module. BUT; next's code splitting means the
|
|
* bundle for each page will include its own copy of the module, _unless it's
|
|
* inlcuded in every page_.
|
|
* - https://github.com/zeit/next.js/issues/659#issuecomment-271824223
|
|
* - https://github.com/zeit/next.js/issues/1635#issuecomment-292236785
|
|
* - Therefore, this test ensures that every page includes that module, and
|
|
* hence it will be shared across every page, giving us a global store in
|
|
* Apollo that we can clear, etc
