use-case: web component development in deno

My use-case is quite simple, really. But I have a hard time finding the tooling to work with it. - I have plain HTML, say "index.html", some CSS, say "app.css", and some typescript. - I want to include this typescript in the HTML. - I want a webserver that reloads the index.html page whenever any of the files changes...

Run all pending ticks synchronously

Currently it seems like run_event_loop is the only way to run all the pending ops that are scheduled including the ones that are scheduled for the next tick. Is there a way to just call the next tick on the runtime?

How can I do server sent events on the client side in deno?

I have a server api which is doing server sent events correctly, I can see it in curl doing what I would expect. One the calling side I have a simple cli written in deno and I'm trying to use an EventSource, which is not a requirement. If there is an easier way I'm all for it. The downside of the EventSource is that it is an event handler api, where you subscribe to on('message', handler) and I'm looking for an async generator api. If I just use the EventSource as is, it appears to not work at all, the process just exits right away as if its not taking out a ref(). If I convert it into an async generator then I"m getting a "Top-level await promise never resolved" error. I'm wondering if anyone has any simple examples of doing server sent events in deno client side? Using EventSource is not required at all....

TC39 stage 3 decorators not working anymore in Deno Deploy

As of Feb 15th, deployments to #deploy™ fail when using TC39 decorators. Despite the decision to support legacy decorators in Deno 1.40+, see @bartlomieju 's post here https://github.com/denoland/deno/issues/19160#issuecomment-1855462766, when compiling, the experimentalDecorators config is ignored and I suspect any decorator, including the TS 5.0 ones, causes compilation to fail. I'm supposed to go live in a few weeks and I my app doesn't run on Deno Deploy anymore. ...

VSCode Extension Failing ot Initialize

Which components exactly should be islands?

Hi! I am currently developing a web app using fresh and I am getting confused about the usage of islands. In the doc it is stated that:

Islands enable client side interactivity in Fresh. Islands are isolated Preact components that are rendered on the server and then hydrated on the client. This is different from all other components in Fresh, as they are usually rendered on the server only.

Islands enable client side interactivity in Fresh. Islands are isolated Preact components that are rendered on the server and then hydrated on the client. This is different from all other components in Fresh, as they are usually rendered on the server only.

However, this is still kind of a vague description for me. Is this the same as: "every component that renders jsx elements with an event handler attached or uses any browser API"? ...
