How can I change the port in Fresh?

I have tried the following in the Main.ts await start(manifest, { port: 3000 }), But I suspect this solution is long outdated. Thx....

How does Fresh run esbuild on Deploy without cache writes?

I'm trying to build some solidjs code during runtime, but I keep getting errors on Deploy because of writes to esbuild cache:

[uncaught application error]: PermissionDenied - Requires write access to '/src/.cache/esbuild/bin', but the file system on Deno Deploy is read-only.

PyCharm notebooks syntax highlight

Hello. I have set up Deno to work with pycharm. I am able to run a jupyter server with Deno kernel selected. Cells execute correctly. One issue I have is that I don't have syntax highlight and autocompletion. Javascript and Typscript plugins are installed and working in .js and .ts files. Is there any other plugin or setting I am missing? I have installed and used Deno kernel in VS Code without any issues. But I definitely prefer pycharm....

Deno does not recognize ".node" extension files

[name].node is C++ (kind of) addons compiled for using in Node.JS (as i get it) It just doesn't allow to run any code with it, since downloading npm:rosu-pp@0.9.4 with Deno, downloads everything EXCEPT index.node, but... default npm install rosu-pp does it, and runs very well, is there something I could do about it? Reproducing problem can be done with this TypeScript + Deno chapter in this paste...

[RESOLVED] Async Route vs Sync Route: Signatures are error-prone

I am new to Deno Fresh and I ran into a strange bug (on my side), when changing a sync route to an async route, because I was getting the Request instead of the RouteContext/PageProps. As in the docs, I was using exported default functions (instead of typed Fat-Arrow-Functions) to define my routes. When changing a route to async, the compiler would not (and could not) warn me, that I am now accessing the wrong property, because at runtime the AsyncRoute will get an extra parameter "Request" as the first (!!!) parameter. A few questions pop up there for me:...

How to actually sign out using deno_kv_auth

Not sure if bug or feature, but I have problems signing out from deno_kv_auth. I'm using Auth0 for testing, but actually the kv auth live demo at https://kv-oauth.deno.dev/ has the same issue, using GitHub provider. Basically, when first visiting the demo, and signing in, you get the GitHub login screen to authorize the sign in. All ok, sign in works. But then you sign out. Yes the session is cleared from the local server, but if you then click sign in again, you don't get the GitHub/Auth0 login screen, but instead get immediately authenticated with the previous credentials, and returned with a new successfully authenticated session....
