Add vertx web client config

[FroMage]

We're using the vertx web client in RESTEasy Reactive, but there's no way to configure it. While we might add jaxrs-client-specific config to override global web client settings, there should be a way to configure the vertx web client globally, possibly in the vertx extension?

Definitely +1 for this idea.

I don't see however how we could make these settings global as the HttpClient is created like so:

vertx.createHttpClient();

The WebClient is created in similar fashion:

WebClient.create(vertx)

Perhaps we need some new SPI in Vertx where we can register the default HttpClientOptions and WebClientOptions?

At the moment the Vert.x Web Client is unmanaged.
Injected a managed one is tricky as configuration (host/port) are likely going to be different every time.

What about a facade like:

WebClient create(WebClientOptions options)

which would merge the options with some default ones and produce the web client?

[geoand]

Yeah, that's a good idea

+1 for this, we need to enable logs in Vert.x Web client and it seems this requires passing WebClientOptions.setLogActivity to true for it to log requests and responses

Do I understand it correctly that Clement's proposal should end up in the quarkus-vertx-http extension?

[cescoffier]

Yes, or in a new extension.
