I had some trouble to get server side rendering with the AWSAppSyncClient working. I finally found a solution in https://github.com/awslabs/aws-mobile-appsync-sdk-js/issues/82 but it might be worth to share it here as well. Instead of adding a big code block to each file I'll just refer to this Pull Request. ______ In case you want to use the `AWSAppSyncClient` you just need to replace the `create()` function with this function: ```jsx import AWSAppSyncClient from 'aws-appsync'; import { AUTH_TYPE } from 'aws-appsync/lib/link/auth-link'; function create(initialState) { const client = new AWSAppSyncClient({ url: AWS_AppSync.graphqlEndpoint, region: AWS_AppSync.region, auth: { type: AUTH_TYPE.API_KEY, apiKey: AWS_AppSync.apiKey, // Amazon Cognito Federated Identities using AWS Amplify //credentials: () => Auth.currentCredentials(), // Amazon Cognito user pools using AWS Amplify // type: AUTH_TYPE.AMAZON_COGNITO_USER_POOLS, // jwtToken: async () => (await Auth.currentSession()).getIdToken().getJwtToken(), }, disableOffline: true, }, { cache: new InMemoryCache().restore(initialState || {}), ssrMode: true }); return client; } ```
