De plus, la meilleure approche était d'utiliser des normes déjà existantes.

Ainsi, avant même de commencer à coder **FastAPI**, j'ai passé plusieurs mois à étudier les spécifications d'OpenAPI, JSON Schema, OAuth2, etc. Comprendre leurs relations, leurs similarités et leurs différences.

## Conception { #design }

Ensuite, j'ai passé du temps à concevoir l'« API » de développeur que je voulais avoir en tant qu'utilisateur (en tant que développeur utilisant FastAPI).
