如果你要开发一个用于终端的 <abbr title="Command Line Interface - 命令行界面">命令行</abbr>应用而不是 Web API，看看 [**Typer**](https://typer.tiangolo.com/)。

**Typer** 是 FastAPI 的小同胞。它的目标是成为**命令行中的 FastAPI**。⌨️ 🚀

FastAPI 站在巨人的肩膀之上：

    @Test
    public void test_createSystemProperties() throws IOException {
        List<String> cmdList = new ArrayList<>();
        cmdList.add("test");
        cmdList.add("command");

        File propFile = new File(tempDir, "test.properties");

        // Mock ComponentUtil.getSystemProperties() to return actual system properties
        Properties systemProps = System.getProperties();

During development in an IDE we would need layered resolution approach that would allow resolution from the workspace, then the local Maven repository and then from any number of remote Maven repositories. During development from the command line we would need a layered resolution approach that would allow resolution from the local Maven repository and then from any number of remote Maven repositories. In production the resolution for the dependencies could also be layered but would depend...

Если вы создаёте приложение <abbr title="Command Line Interface - Интерфейс командной строки">CLI</abbr> для использования в терминале вместо веб-API, посмотрите [**Typer**](https://typer.tiangolo.com/).

**Typer** — младший брат FastAPI. И он задуман как **FastAPI для CLI**. ⌨️ 🚀

## Replication - Processes and Memory { #replication-processes-and-memory }

With a FastAPI application, using a server program like the `fastapi` command that runs Uvicorn, running it once in **one process** can serve multiple clients concurrently.

But in many cases, you will want to run several worker processes at the same time.
