Support for SSE? #395
Description
first, thanks for HTMLUnit, first time I am using it and it is really nice.
I tried to test a javalin web app with SSE (server side events), plus htmx on the client side (you tweeted about it a few weeks ago, see https://twitter.com/HtmlUnit/status/1447250140423770122).
So, here is my setup:
private final Javalin app;
private final ConcurrentLinkedQueue<SseClient> clients = new ConcurrentLinkedQueue<>();
app.sse("sse-events", client -> {
clients.add(client);
client.onClose(() -> clients.remove(client));
});<div class="container mx-auto px-40 pb-10">
<div hx-sse="connect:/sse-events">
<div hx-sse="swap:box-update">
<div class="flex pl-4 pr-4 pt-4 pb-4 mt-4 mb-4" id="sse-element">
<div class="flex-grow content text-text"> </div>
</div>
</div>
</div>
</div>Test looks like this
try (final WebClient webClient = new WebClient()) {
webClient.getOptions().setRedirectEnabled(true);
webClient.getOptions().setCssEnabled(false);
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
webClient.setJavaScriptErrorListener(new DefaultJavaScriptErrorListener());
final HtmlPage mainPage = webClient.getPage("http://localhost:7000/");
...
}Running that test in debug mode, leads to the sse-events endpoint not being called, despite part of the HTML that the mainpage returns.
Hope this helps as a start, otherwise I can try to provide a minimal fully reproducible example.
