FastAPI and GraphQL - build your first API

API Development with FastAPI, GraphQL, SQLAlchemy, Alembic, PostgreSQL, Uvicorn and Docker. In this tutorial we take a first look at building an API with FastAPI and GraphQL. We build an API that will allow posting, mutations and queries. SQLAlchemy + Alembic is used to manage migrations, PostgreSQL + PGAdmin all wrapped deployed in Docker/Docker-Compose.

Amazing tutorial.
If you're coming here in 2023, here's a couple of things you need to know.
1. graphql is no longer accessible through starlette, use from starlette_graphene3 import GraphQLApp
2. app.add_route is nolonger valid, use app.mount
3. to get the GUI, you'll need make_graphiql_handler() from starlette_graphene3.

Your imports should be:
from starlette_graphene3 import GraphQLApp, make_graphiql_handler

your route method should be:
app.mount("/graphql", GraphQLApp(schema=graphene.Schema(query=Query, mutation=PostMutations), on_get=make_graphiql_handler()))

I'm a Cuban Brazilian and found this tutorial incredible, you are the best!!!

If you installed starlette > 0.17 .0 you should install starlette-graphene3, so to use "from starlette_graphene3 import GraphQL Api" instead "from starlette.graphql import GraphQLApp"

This is great. I like tutorials that explore how to build a real project showing how different technologies interact and integrate. Hope to see more.

[tonyromano]

Couldn't find another tutorial like this anywhere. Thanks for doing this!

[jdpenuliar]

The starlette-graphene3 is not being recognized by FastAPi() anymore. Been looking at some docs but it seems it was deprecated? Specifically on the GraphQLApp part. Any suggestions or updates?

[pipi_delina]

There has been some form of a refactor of the Graphene Code, I will be very happy if you do another video based on the current specifications.

[davishek]

Wow, asked you last time. thanks for this again.

[gtv]

Your videos are freaking amazing, im surprised u only have 17k followers.

[justacasualdeveloper]

Awessome Video as always. Thanks man 😊.

[abdoramandawud]

An awesome video as always. Hope best man 😉

[Haggyk]

Is there a similar Video with MongoDB?

[shalineesharma]

starlette.graphql has been deprecated. What can I use in place of it such that all other dependencies remain just the same ?

[pipi_delina]

I am asking again if you can give us a new update on this... cant seem to figure out why graphene and starlette are not resolving although they are installed

[elysium-hf]

Great tutorial, but i'm getting this error "cannot import name 'connection_from_list_slice' from, do you have any idea about why this is happening or how i could solve it?

[munivinayk]

Hello. I have used your approach and made minor changes to be able to use it from the react front end. For Fast API i have added CORS middleware and calling them using fetch fucntions in react. However, since i have added this middle ware to the Fastapi, i am getting the following error: "SLL SYCALL Error: EOF detected". This would happen, when i keep the session idle for few mins. I will have to always restart the docker to be able to resume the operations back. do you happen to know what would be causing this error?

[anthonyvetrenko]

It's super awesome, keep going!
May you please also show an example with relations in DB and how to manage them in graphql?

[abrarshahid]

Your videos are just like Diamonds to
Btw, I have a question.
May I know your opinion about Django vs FastAPI?

[ericsalesdeandrade]

Real helpful thank you. What version of Python are you using?

[kunyan]

Why is it true that when I log in to PGadmin, I am prompted to check my password when I am told that my password is compromised
