Stateless Components not working with SSR

throws this error: ComponentClass is not a constructor
with this stack:

TypeError: ComponentClass is not a constructor at getQueriesFromTree (/Users/alex/djcode/another_example_app/frontend/src/server.ts:48:23) at getQueriesFromTree (/Users/alex/djcode/another_example_app/frontend/src/server.ts:67:5) at /Users/alex/djcode/another_example_app/frontend/src/server.ts:73:54 at forEachSingleChild (/Users/alex/djcode/another_example_app/frontend/node_modules/react/lib/ReactChildren.js:52:8) at traverseAllChildrenImpl (/Users/alex/djcode/another_example_app/frontend/node_modules/react/lib/traverseAllChildren.js:69:5) at traverseAllChildren (/Users/alex/djcode/another_example_app/frontend/node_modules/react/lib/traverseAllChildren.js:164:10) at Object.forEachChildren [as forEach] (/Users/alex/djcode/another_example_app/frontend/node_modules/react/lib/ReactChildren.js:72:3) at getQueriesFromTree (/Users/alex/djcode/another_example_app/frontend/src/server.ts:73:14) at getQueriesFromTree (/Users/alex/djcode/another_example_app/frontend/src/server.ts:67:5) at getQueriesFromTree (/Users/alex/djcode/another_example_app/frontend/src/server.ts:67:5)

This occurs only with Stateless Components, which work fine when rendered on the client but break when rendered on the server with react-apollo and react-router.

This is the immediately surrounding code:

  const App = (
    <ApolloProvider client={client} >
      <RouterContext {...renderProps} />
    </ApolloProvider>
  )

  const { markup, initialState } = await renderToStringWithData(App)

When I only have class-based components, everything works. When I have a Stateless component anywhere in my hierarchy, I get the above error.

Version

• apollo-client@0.5.0
• react-apollo@0.5.14
• react@15.3.2

This also occurs when <RouterContext /> is not used

That's interesting, I'm pretty sure it does work in some cases (for instance GitHunt has some SFCs). In any case, I'm going to refactor this code soon, thanks for reporting it.

[rattrayalex]

Awesome, thanks @tmeasday ! Looking forward.

Fixed in 0.6.0 (I think?)
