have been deprecated and will be removed in a future release.  Callers should switch to using `wait.PollUntilContextCancel`, `wait.PollUntilContextTimeout`, or `wait.ExponentialBackoffWithContext` as appropriate.
  
  `PollWithContext(Cancel|Deadline)` will no longer return `ErrWaitTimeout` - use the `Interrupted(error) bool` helper to replace checks for `err == ErrWaitTimeout`, or compare specifically to context errors as needed. A future release will make the `ErrWaitTimeout` error...

Pour y parvenir, vous aurez normalement un **programme séparé** qui s'assure que votre application est lancée au démarrage. Et dans de nombreux cas, il s'assurera également que d'autres composants ou applications sont également lancés, par exemple une base de données.

### Exemples d’outils pour lancer au démarrage { #example-tools-to-run-at-startup }

Voici quelques exemples d'outils capables de faire ce travail :

E0080..E00FF  ; disallowed                             # NA   <reserved-E0080>..<reserved-E00FF>

## GitHub'da **FastAPI**'ye yıldız verin { #star-fastapi-in-github }

## `fastapi` sürümünü sabitleyin { #pin-your-fastapi-version }

İlk yapmanız gereken, kullandığınız **FastAPI** sürümünü uygulamanızla doğru çalıştığını bildiğiniz belirli bir güncel sürüme "sabitlemek" (pinlemek) olmalı.

Örneğin, uygulamanızda `0.112.0` sürümünü kullandığınızı varsayalım.

`requirements.txt` dosyası kullanıyorsanız sürümü şöyle belirtebilirsiniz:
