# Module `app`
Ce module permet de récupérer des informations sur les applications actives dans l'environnement Edge courant.
## Méthodes
### `app.list(ctx: Context): []Manifest`
Récupère la liste des applications actives.
#### Arguments
- `ctx` **Context** Le contexte d'exécution. Voir la documentation du module [`context`](./context.md)
#### Valeur de retour
Liste des objets `Manifest` décrivant chaque application active.
### `app.get(ctx: Context, appId: string): Manifest`
Récupère les informations de l'application identifiée par `appId`.
#### Arguments
- `ctx` **Context** Le contexte d'exécution. Voir la documentation du module [`context`](./context.md)
- `appId` **string** Identifiant de l'application
#### Valeur de retour
Objet `Manifest` associé à l'application, ou `null` si aucune application n'a été trouvée correspondant à l'identifiant.
### `app.getUrl(ctx: Context, appId: string): Manifest`
Retourne l'URL permettant d'accéder à l'application identifiée par `appId`.
#### Arguments
- `ctx` **Context** Le contexte d'exécution. Voir la documentation du module [`context`](./context.md)
- `appId` **string** Identifiant de l'application
#### Valeur de retour
URL associée à l'application ou `null`, ou `null` si aucune application n'a été trouvée correspondant à l'identifiant.
## Objets
### `Manifest`
```typescript
interface Manifest {
id: string // Identifiant de l'application
version: string // Version de l'application
title: string // Titre associé à l'application
description: string // Description associée à l'application
tags: string[] // Mots clés associés à l'application
}
```
