## Older `GraphQLApp` from Starlette { #older-graphqlapp-from-starlette }

Previous versions of Starlette included a `GraphQLApp` class to integrate with [Graphene](https://graphene-python.org/).

It was deprecated from Starlette, but if you have code that used it, you can easily **migrate** to [starlette-graphene3](https://github.com/ciscorn/starlette-graphene3), that covers the same use case and has an **almost identical interface**.
