# GraphQL { #graphql }

Comme **FastAPI** est basé sur la norme **ASGI**, il est très facile d'intégrer toute bibliothèque **GraphQL** également compatible avec ASGI.

Vous pouvez combiner des *chemins d'accès* FastAPI classiques avec GraphQL dans la même application.

/// tip | Astuce

**GraphQL** résout des cas d'utilisation très spécifiques.

Il présente des **avantages** et des **inconvénients** par rapport aux **API web** classiques.

### OAuth 1 { #oauth-1 }

Il y a eu un OAuth 1, très différent d'OAuth2, et plus complexe, car il incluait des spécifications directes sur la manière de chiffrer la communication.

Il n'est plus très populaire ni utilisé de nos jours.

OAuth2 ne spécifie pas comment chiffrer la communication ; il suppose que votre application est servie en HTTPS.

// blocks until the mutex is available.
func (lm *LRWMutex) Lock() {
	const isWriteLock = true
	lm.lockLoop(context.Background(), lm.id, lm.source, math.MaxInt64, isWriteLock)
}

// GetLock tries to get a write lock on lm before the timeout occurs.
func (lm *LRWMutex) GetLock(ctx context.Context, id string, source string, timeout time.Duration) (locked bool) {
	const isWriteLock = true

## Dependency tree and scopes { #dependency-tree-and-scopes }

Let's review again this dependency tree and the scopes.
