How to use 2 terminating Links?

[vendramini]

Hello everyone.

I read the docs about terminating links, but what about the situations which we need to use the behavior of different terminating links?

My case is: I'm using apollo-upload-client for upload and I would like to use apollo-link-batch-http to improve performance request.

So this code says that I can't have 2 terminating links:

export default function createApolloClient(initialState, ctx)
{
    // The `ctx` (NextPageContext) will only be present on the server.
    // use it to extract auth headers (ctx.req) or similar.
    const httpLink = createUploadLink({
        uri: `${process.env.NEXT_PUBLIC_API_URL}/graphql`,
        credentials: 'same-origin',
        fetch,
    });

    const batchLink = new BatchHttpLink(
        {
            uri: `${process.env.NEXT_PUBLIC_API_URL}/graphql`,
            credentials: 'same-origin',
            fetch,
        }
    );

    const authLink = setContext((_, { headers }) =>
    {
        // get the authentication token from local storage if it exists
        const token = Cookies.get('token');
        // return the headers to the context so httpLink can read them
        return {
            headers: {
                ...headers,
                authorization: token ? `Bearer ${ token }` : "",
            }
        }
    });

    return new ApolloClient({
        ssrMode: Boolean(ctx),
        link: from([authLink, batchLink, httpLink]),
    })
}

What is the best approach in this kinda of problem?
