もし Web API の代わりにターミナルで使用する<abbr title="Command Line Interface">CLI</abbr>アプリを構築する場合は、<a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a>を確認してください。

**Typer**は FastAPI の弟分です。そして、**CLI 版 の FastAPI**を意味しています。

## 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.

### Multiple Processes - Workers

  public NullPointerTester() {
    try {
      /*
       * Converter.apply has a non-nullable parameter type but doesn't throw for null arguments. For
       * more information, see the comments in that class.
       *
       * We already know that that's how it behaves, and subclasses of Converter can't change that
       * behavior. So there's no sense in making all subclass authors exclude the method from any

আপনি যদি <abbr title="Command Line Interface">CLI</abbr> অ্যাপ বানাতে চান, যা কিনা ওয়েব API এর পরিবর্তে টার্মিনালে ব্যবহার হবে, তাহলে দেখুন<a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a>.

So, it's really important that you actually read and run the code, and let me know in the comments that you did. 🤓

	errorLine     int   // Line number of last error.
