Response data, is not altered, attributes are kept with their original name, value are not casted (for now). the only thing done, is the object structure, which is flatten, empty (as is XML NODATA) attributes are removed

For consitancy with OPMET and SIGMET, messages from VAA & TCA messages are grouped by station.

There are also some static methods wich return list of avaliable stations and options.

Aeroweb.VAA
Aeroweb.VAAG
Aeroweb.TCA
Aeroweb.TCAG
Aeroweb.PREDEC
Aeroweb.CARTES

They are populated with data in MeteoFrance documentation.

Frequent Issues

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://aviation.meteo.fr/FR/aviation/serveur_donnees.jsp?ID=API_KEY&TYPE_DONNEES=VALIDATION&CODE_METEO=SomeUser. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

Aeroweb server will not set Access-Control-Allow-Origin header, preventing you from using it directly from browser. You'll need some sort of Proxy, or ServiceWorker to add this header.

for exemple, using a proxy :

let aero = new Aeroweb("API_KEY", {prefetch: (request) => new Request("https://cors-anywhere.herokuapp.com/" + request.url, request); })
