defaultOptions do not work

I tried setting defaultOptions like this:

export const apolloClient = new ApolloClient({
  link,
  cache,
  connectToDevTools: true,
  defaultOptions: {
    watchQuery: {
      fetchPolicy: 'cache-and-network'
    },
    query: {
      fetchPolicy: 'cache-and-network'
    }
  }
})

and yet re-rendering of components does not trigger refetching, however manually setting fetchPolicy option on a particular component does achieve the intended result

Okay, guys, I think the reason is you should provide all 3 properties together (watchQuery, query and mutate):

This code works

const defaultOptions = {
  watchQuery: {
    fetchPolicy: 'cache-and-network',
    errorPolicy: 'ignore',
  },
  query: {
    fetchPolicy: 'network-only',
    errorPolicy: 'all',
  },
  mutate: {
    errorPolicy: 'all'
  }
}

This code doesn’t affect to default options:

const defaultOptions = {
  query: {
    fetchPolicy: 'network-only',
    errorPolicy: 'all',
  },
  mutate: {
    errorPolicy: 'all'
  }
}

or…

const defaultOptions = {
  query: {
    fetchPolicy: 'network-only',
    errorPolicy: 'all',
  }
}

@helios1138 @stefanholzapfel @sfilipov @hwillson please check it. It works for me.

You have to declare defaultOptions as a constant like this:

const defaultOptions = {
  watchQuery: {
    fetchPolicy: 'cache-and-network',
    errorPolicy: 'all',
  },
  query: {
    fetchPolicy: 'cache-and-network',
    errorPolicy: 'all',
  },
  mutate: {
    errorPolicy: 'all',
  }
}

const client = new ApolloClient({
  link: from([
    logoutLink,
    errorsLink,
    httpLink
  ]),
  cache: new InMemoryCache(),
  defaultOptions
});
