# Http

Dans une application Angular, la plupart des données proviennent d'API ReST où les échanges de données se font via des requêtes HTTP. Cf. notre "white paper" sur les bonnes pratiques et la sécurité des API ReST <https://blog.wishtack.com/api-rest-bonnes-pratiques-et-securite/>.

Pour produire des requêtes HTTP, Angular fournit un service `HttpClient` qui est un wrapper de la classe native (et vieillissante) `XMLHttpRequest`.
