Known issues

due to how MockedProvider works in Apollo, you will have to hard refresh when visiting sub stories (visiting stories that exist in the same file) to get the expected results, please upvote my comment here to see if we can get this fixed: https://github.com/apollographql/apollo-client/issues/9738#issuecomment-1606316338

Upgrading from a previous version below 6.x

In previous versions, we had a decorator called withApolloClient this is no longer nesscessary. If you're upgrading from this API here are the following changes that you'll need to make:

1. remove all code referencing the deprecated withApolloClient decorator.
2. follow install instructions

Writing your stories with queries

1import DashboardPage, { DashboardPageQuery } from ".";
2
3export default {
4  title: "My Story",
5};
6
7export const Example = () => <DashboardPage />;
8
9Example.parameters = {
10  apolloClient: {
11    mocks: [
12      {
13        request: {
14          query: DashboardPageQuery,
15        },
16        result: {
17          data: {
18            viewer: null,
19          },
20        },
21      },
22    ],
