Best practice to import internal components

Many examples show that importing with file extensions is simple, but these todo examples are not connected to real-life scenarios. In reality, components are not just a single file (they include styles, tests, and the component itself), and you typically store each component in its own folder. This leads to duplicated imports like Button/Button.tsx, which look messy. For example, my project structure is as follows: ``` /...

`deno install` installs workspace members' npm dependencies, but not jsr dependencies?

In a monorepo setup, does deno install install the dependencies of workspace members? I couldn't find any mention of this behavior in either the deno install documentation or the workspace documentation, so I'm unsure if this is the expected behavior. Consider the following monorepo structure:...

Can I import/reference Deno's TypeScript when bundling types?

I have the following import in a script that uses ts-morph to pull some types from TypeScript (TypeScript is currently pulled in via package.json as an entry in devDependencies):

import { version } from 'typescript';

VSC having issues with NextJS using Deno

so I installed Deno and NextJS and have successfully run both the front and backend, but unfortunately it seems like it's throwing lots of extra errors with the tsx renderer. example error:

Relative import path "next/image" not prefixed with / or ./ or ../
  hint: If you want to use a JSR or npm package, try running `deno add jsr:next/image` or `deno add npm:next/image`deno(import-prefix-missing)

Cannot import when index.d.ts file

This is largely a question about node compatibility as what I really want is to run my existing large node/typescript project in Deno so that I can get good jupyter integration. I've managed to figure things out to where they mostly work but am running into issues where my existing code uses the npm type-fest package to provide advanced typescript types. So as an example, I have the following import in my code ``` import { LiteralUnion } from 'type-fest'...

SIGSEGV (invalid memory reference) after returning a freshly-compiled function

Hi all, apologies if this is not the right place to ask, but we're hitting an invalid memory reference error when using deno_core and would like to ask for help narrowing the problem down or even identifying the cause of the error. Here's a bit more context: we're using the deno_core crate to write a transpiler/interpreter[1] for the Nix language[2]....

Possible to use Deno.test for callbacks?

I've been implementing tests to make sure the porting of my main project to Deno is working out as expected, coupled with this is a WebSocket server done with Deno.serve. For this the test needs to handle both a server and client session, waiting for callbacks to come through. Right now my test finishes prematurely even if I await the termination of the server, I need to set both sanitizeOps: false and sanitizeResources: false to have the test finish at all, but then it skips any assert defined in the callbacks. My previous experience is with Mocha where we get the done callback to run to finish the current test, but for Deno.test I only see us getting the option to make the test caller asynchronous, which in this case doesn't seem to help me....
