Traefik Middleware which allows filtering GraphQL queries by different limits

Options

DepthLimit

Optional, Default: 0

Check if the query depth does not exceed the limit. We count depth as each selection set, excluding top-level

Check if the query does not have more batches than limit

Check if query total number of nodes does not exceed the limit. We defined node as a selection set excluding top-level wrappers
