feat: Update the GraphQL page

Update the GraphQL page from GraphiQL to GraphQL Playground by Prisma Labs. It provides a better and Interactive UI for testing and checking Endpoints. Demo

I could make a PR for the same by Changing the contents of the GRAPHIQL variable here https://github.com/encode/starlette/blob/c5239ba89bc273645c82bd76bce185a5bd4964c7/starlette/graphql.py#L147-L279 I’ll start working on this if this gets a green flag 😅 😅

Hey @tomchristie I actually Tried it by playing a bit with Source code and it actually worked and really well too…

import graphene
from fastapi import FastAPI
from starlette.graphql import GraphQLApp


class Query(graphene.ObjectType):
    hello = graphene.String(name=graphene.String(default_value="stranger"))

    def resolve_hello(self, info, name):
        return "Hello " + name

#
app = FastAPI()
app.add_route("/", GraphQLApp(schema=graphene.Schema(query=Query)))

This is the source code for it

I think I probably just need to leave this one in other folk’s hands.

I’d be totally happy with someone starting up a project based on the existing graphql.py and associated tests & docs. If someone happens to take a propactive lead on that, then we can consider deprecating the built-in option, and instead start linking out to third parties instead.
