You can optionally deploy your FastAPI app to <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>, go and join the waiting list if you haven't. 🚀

If you already have a **FastAPI Cloud** account (we invited you from the waiting list 😉), you can deploy your application with one command.

There are special blocks surrounded by four slashes («////»). They mark text, which will be rendered as part of a tab in the final document. The scheme is:

    //// tab | {tab title}
    {tab content, may span many lines}
    ////

Keep everything before the vertical bar («|») as is, including the vertical bar. Translate the tab title. Translate the tab content, applying the rules you know. Keep the four block closing slashes as is.

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.

Make sure you evaluate if the **benefits** for your use case compensate the **drawbacks**. 🤓

## GraphQL Libraries { #graphql-libraries }

Here are some of the **GraphQL** libraries that have **ASGI** support. You could use them with **FastAPI**:

    An HTTP exception you can raise in your own code to show errors to the client.

    This is for client errors, invalid authentication, invalid data, etc. Not for server
    errors in your code.

    [FastAPI docs for Handling Errors](https://fastapi.tiangolo.com/tutorial/handling-errors/).
