I use apollo-server-lambda with serverless-framework and able to deploy aws lambda graphql, ariadne will be able to make on aws lambda too?

Thanks.

I dont know about AWS, but using Google Cloud Functions the code below works.

from ariadne import QueryType, graphql_sync, make_executable_schema, gql
from ariadne.constants import PLAYGROUND_HTML
from flask import Flask, request, jsonify

type_defs = gql("""
    type Query {
        hello: String!
    }
""")

query = QueryType()

@query.field("hello")
def resolve_hello(_, info):
    request = info.context
    user_agent = request.headers.get("User-Agent", "Guest")
    return "Hello, %s!" % user_agent


schema = make_executable_schema(type_defs, query)

def endpoint(request):
    
    if request.method == 'POST':
        
        # GraphQL queries are always sent as POST
        data = request.get_json()
        
        # Note: Passing the request to the context is optional.
        # In Flask, the current request is always accessible as flask.request
        success, result = graphql_sync(
            schema,
            data,
            context_value=request
        )

        status_code = 200 if success else 400
        return jsonify(result), status_code
    
    else:
        return PLAYGROUND_HTML, 200

how do you deploy to google cloud function?
by using google cloud function cli or any other tools?
if you can share your project structure then would be great!

There are many ways to deploy a google cloud function. But using the web interface I believe be the easier way.

Try to follow this tutorial https://rominirani.com/google-cloud-functions-tutorial-writing-our-first-google-cloud-function-a62de60b5c90

Instead of node, select python 3.7 as the runtime.

In the code editor past the code above and for the requirements.txt use this:

# Function dependencies, for example:
# package>=version
