react-helmet-async missing HelmetProvider export

I'm on the canary version testing out jsxImportSourceTypes and ran into an issue when switching to using npm specifiers for react@18.0.2. I have the following entry in my deno.jsonc imports.

"react-helmet-async": "npm:react-helmet-async@2",

"react-helmet-async": "npm:react-helmet-async@2",

My editor has no issue showing that it recognizes the HelmetProvider. You can see in the attached screenshots that it is recognizing that I'm importing the class. However, when my code runs, I get the following error....

Where has std/hash/sha3.ts gone?

Basically what the title says. This was removed from std/ at some point, but I can't find the current location of the module anymore (looking it up on deno.land returns nothing).

Loading a module with `.load_main_es_module_from_code()` and TS module loader doesn't transpile

While working on a script runtime I ran into a curious issue where the main module I load doesn't get transpiled. This may well be my lack of understanding of how deno_core crate works but the case seemed so mind boggling to me I created a small repo for reproduction. The TLDR is: 1. I have a script.ts that I load and evaluate at runtime. 2. The script.ts uses functions from a helper library script-api.ts...

StaticModuleLoader: why must the ModuleSpecifier be a URL?

hey everyone, I'm trying to pass a StaticModuleLoader to my runtime to enable specific imports. Each module for the StaticModuleLoader is specified by a ModuleSpecifier (type alias for url::Url) and the corresponding code (impl IntoModuleCodeString). I'm wondering why the module has to be specified by a url. I read here https://choubey.gitbook.io/internals-of-deno/foundations/resolve_url_or_path that the url is crucial because it allows Deno to locate and access the modules. But I'm already providing the code in form of the value that implements IntoModuleCodeString. If I want to enable an import such as import foo from "bar"; in the code that runs on the runtime, what would the ModuleSpecifier url look like that I have to pass to the StaticModuleLoader?...

Writing CSS in Fresh

Are there any alternatives in how we write CSS other than Tailwind-like (inline & abbreviated)? I personally like the normal key-value & scoped styling. But it seems that tool like styled-components is an anti-pattern to Fresh....

How to abstract tests to allow running different functions against the same test suite?

I've set up two suites of tests like this: https://github.com/gustwindjs/gustwind/tree/develop/htmlisp/html-tests, https://github.com/gustwindjs/gustwind/tree/develop/htmlisp/html-tests-sync . They are effectively the same but one is for async code and one for sync. Due to how the language works, technically it should be possible to use the async test suite for testing the sync code since await just wraps sync result within a Promise. The question is, what would be a sane way to extract the...
