### Run Automatically on Startup { #run-automatically-on-startup }

In general, you will probably want the server program (e.g. Uvicorn) to be started automatically on server startup, and without needing any **human intervention**, to have a process always running with your API (e.g. Uvicorn running your FastAPI app).

  /** Returns a joiner which automatically places {@code separator} between consecutive elements. */
  public static Joiner on(char separator) {

But if you return a `Response` directly (or any subclass, like `JSONResponse`), the data won't be automatically converted (even if you declare a `response_model`), and the documentation won't be automatically generated (for example, including the specific "media type", in the HTTP header `Content-Type` as part of the generated OpenAPI).

/// tip

FastAPI automatically generates **OpenAPI 3.1** specifications, so any tool you use must support this version.

Hug inspired parts of APIStar, and was one of the tools I found most promising, alongside APIStar.

Hug helped inspiring **FastAPI** to use Python type hints to declare parameters, and to generate a schema defining the API automatically.

The replication configuration follows [AWS S3 Spec](https://docs.aws.amazon.com/AmazonS3/latest/dev/replication-add-config.html). Any objects uploaded to the source bucket that meet replication criteria will now be automatically replicated by the MinIO server to the remote destination bucket. Replication can be disabled at any time by disabling specific rules in the configuration or deleting the replication configuration entirely.

If you are curious about how the raw OpenAPI schema looks like, FastAPI automatically generates a JSON (schema) with the descriptions of all your API.
