**FastAPI** wouldn't exist if not for the previous work of others.

There have been many tools created before that have helped inspire its creation.

I have been avoiding the creation of a new framework for several years. First I tried to solve all the features covered by **FastAPI** using many different frameworks, plug-ins, and tools.

But Facebook login doesn't support OpenID Connect. It has its own flavor of OAuth2.

### OpenID (not "OpenID Connect") { #openid-not-openid-connect }

There was also an "OpenID" specification. That tried to solve the same thing as **OpenID Connect**, but was not based on OAuth2.

So, it was a complete additional system.

It is not very popular or used nowadays.

## OpenAPI { #openapi }

Now, as Swagger UI didn't support multiple JSON Schema examples (as of 2023-08-26), users didn't have a way to show multiple examples in the docs.

To solve that, FastAPI `0.103.0` **added support** for declaring the same old **OpenAPI-specific** `examples` field with the new parameter `openapi_examples`. 🤓

**your own deployment system** while taking care of the other deployment concepts yourself.

Check out the next chapter to learn about **FastAPI** with containers (e.g. Docker and Kubernetes). You will see that those tools have simple ways to solve the other **deployment concepts** as well. ✨...

In discussions and PRs, in many cases, people bring their frustration and show it without filter, in many cases exaggerating, complaining, being entitled, etc. That's really not nice, and when it happens, it lowers our priority to solve their problems. But still, try to breath, and be gentle with your answers.

Try to avoid using bitter sarcasm or potentially passive-aggressive comments. If something is wrong, it's better to be direct (try to be gentle) than sarcastic.

# Recipes

We've written some recipes that demonstrate how to solve common problems with OkHttp. Read through them to learn about how everything works together. Cut-and-paste these examples freely; that's what they're for.

### Synchronous Get ([.kt][SynchronousGetKotlin], [.java][SynchronousGetJava])

Please discuss your change in a Github issue before spending much time on its
implementation. We sometimes have to reject contributions that duplicate other
efforts, take the wrong approach to solving a problem, or solve a problem which
does not need solving. An up-front discussion often saves a good deal of wasted
time in these cases.

We normally immediately reject isolated PRs that only perform simple
