# Bigger Applications - Multiple Files

If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure

Let's say you have a file structure like this:

```

import java.util.Map;
import java.util.Set;
import java.util.function.Consumer;

import org.codelibs.core.lang.StringUtil;
import org.codelibs.fess.Constants;
import org.codelibs.fess.util.ComponentUtil;
import org.lastaflute.web.util.LaRequestUtil;
import org.opensearch.index.query.BoolQueryBuilder;
import org.opensearch.index.query.MatchAllQueryBuilder;
import org.opensearch.index.query.QueryBuilder;
import org.opensearch.index.query.QueryBuilders;

import org.codelibs.fess.exception.FessSystemException;
