Node-API related segmentation fault

Any idea what could be causing this crash? I'm using Node-API and the same module is working fine in Node.js. Can't figure out the exact part causing this to create a reproducible example 🤔

anyone have a modern container workflow for the serverless framework?

I was able to find code that executed at one point in time. It no longer does. I’d really like to instead get fresh or deno into a container and use serverless to make it work on aws. this is at least as of current a requirement for all code at my workplace and is a hard must to hit production with deno....

How to deno up nuxt?

Setting up Nuxt3: When learning more about V8 and the node.js architecture I became aware of deno. Diving deeper into DENO and being aware of prototype pollution and other important IT security aspects I would like to set up nuxt via DENO right from the beginning... It it already possible or what needs to be done? #nuxt...

google cloud SDKs

Hi all, I am building an application that interacts with google cloud apis, specifically google play app store api's. In a deno runtime environment I am finding it super hard to build such a system because there are no easy ways to handle oauth authentication strategies....

Dates don't increment correctly

when I run the below function with the specific date 2023-09-30, I get the result of n-1 (for any number > 0), where n is the number of the increment specified. It is only this specific date that appears to have this issue, if I change the Year, Month and/or Day it works. function addDay(date, days) {...

Hi, can anyone direct me to the repo/functions where the deno/fresh project generator is held?

I am looking to add functionality to this project generator but I'm not familiar enough to really find it. I am a noob.

Speed of generators

How fast are JS generators when used as iterators? To be clear, I see the for..of loop being very slow compared to a plain for or while loop when used on arrays. Is it because the for..of loop is inherently slow or because the iterator behind it is slow?...

Parsing HTML/XML

Lately I've been researching how to write a simple HTML/XML -> JSON converter. My syntax isn't completely standard HTML (i.e., <Button> is possible) which makes this a notch harder than it probably should be. Here's an example of how things should work: https://github.com/gustwindjs/gustwind/blob/feat/html-prototype/html-to-breezewind/tests/element_test.ts . The current implementation relies on https://deno.land/x/deno_dom but the problem is that it's losing information for tagName. I cannot use it to tell a button apart from a Button as it's uppercasing the tag by default. As an alternative, I looked into https://deno.land/x/xml but it's losing structural information due to its automatic grouping (i.e., it folds divs within a single array and loses their relative positioning so I cannot map the structure later on to match the original)....

LSP badly resolves relative imports between cached modules

I don't really understand this, but it looks to me like the LSP / VS Code has started resolving relative imports between cached modules badly. I'm running under a devcontainer, with the project root in /workspace/ and $DENO_DIR is /deno/.cache/deno . I can run my unit tests from a terminal ok, but if I try to run them in VS Code I get a "Module Not Found" error popup that shows an attempt to import a module from /workspace/deno/.cache/deno/.... If I open the (cached) module containing the failing import and hover the import statement I see a popup with the "Resolved Dependency" in the wrong place, outside the cache. Screenshots attached....
