## FastAPI Experts

These are the users that have been [helping others the most with questions in GitHub](help-fastapi.md#help-others-with-questions-in-github). 🙇

They have proven to be **FastAPI Experts** by helping many others. ✨

/// tip

You could become an official FastAPI Expert too!

Just [help others with questions in GitHub](help-fastapi.md#help-others-with-questions-in-github). 🤓

This is very useful when you need to:

* Have shared logic (the same code logic again and again).
* Share database connections.
* Enforce security, authentication, role requirements, etc.
* And many other things...

All these, while minimizing code repetition.

## First Steps { #first-steps }

Let's see a very simple example. It will be so simple that it is not very useful, for now.

### 3. Setup MinIO with etcd

MinIO server expects environment variable for etcd as `MINIO_ETCD_ENDPOINTS`, this environment variable takes many comma separated entries.

```
export MINIO_ETCD_ENDPOINTS=http://localhost:2379
minio server /data
```

		if typ == unexpectedFileMode || typ&os.ModeSymlink == os.ModeSymlink {
			fi, err := Stat(pathJoin(dirPath, string(name)))
			if err != nil {
				// It got deleted in the meantime, not found
				// or returns too many symlinks ignore this
				// file/directory.
				if osIsNotExist(err) || isSysErrPathNotFound(err) ||
					isSysErrTooManySymlinks(err) {
					continue
				}
				return err
			}

A "build session" represents a single invocation of Gradle, for example when you run `gradlew build`.
A session runs the build one or more times.
For example, when continuous build is enabled, the session may run the build many times, but when it is disabled, the session will run the build once only.

The build session state is managed by the `BuildSessionState` class.
