TestContainers are broken in Deno.
I'm was trying to set up testcontainers https://testcontainers.com/ in deno. Their SDK makes a socket connection to local docker using node http. However, this same connection is broken in deno. I'm just wondering if it's my machine or something is wrong with node:http. Here is more info https://github.com/denoland/deno/issues/27675
Super slow LSP with Deno + VSCode
We experience a really degraded DX in our IDE (VSCode) since we migrated to Deno 2.1.2.
We have a Deno workspace with some backend services and a React SPA built with Vite.
- Slow start (lots of "Loading...")
- Blinking stuff (colors change, underlines, inferred types...)
- Slow (lots of "Loading...") when we open a file for the first time....
Deno compile with SupaBase doesn't work
I created a little authentication client that works on deno very well, connecting to a supabase istance. However, when i compile the code, it doesn't work. It seems to be unable to compile Typescript into JS for some reason.
Is Deno a good JS runtime for embedding into another application?
Hi,
I am looking for a Js runtime that I could easily embed into my application.
I would like to allow scripting for the users of my application to extend its capabilities.
The reason I am considering Deno is because of its security features.
Is Deno a good candidate for this?...
How to customize daisyui default theme?
Hello, I'm trying to define a new value for the light theme for daisyui. The trouble I'm running into is with the tailwind.config.ts where I'm unable to use the require statement as directed in their docs to import the existing classes: https://daisyui.com/docs/themes/#-7. Not really sure where to go from here.
I need ideas for different ways to dig into the Deno API's and its standard library
I am new-ish to Typescript, but I have been a programmer for over a decade. I'm giving myself a challenge to do a new thing with Deno every day for 100 days. https://github.com/kimdcottrell/hundo-days-of-deno
Over the next few days, I'm thinking I can test out:
- Deno.connect() and the node-mysql2 lib...
Relative import path "oak/router" not prefixed with / or ./ or ../ and not in import map
I get the above message when attempting to deploy to Deno Deploy via github actions. The same does not occur when running locally with

# ......ONNX fails in Deno Deploy
Hey Deno community.
We have been putting a lot of work into ONNX on Deno, a good friend put our an amazing article showing how to do it. However, we are facing trouble when trying to run it on Deno Deploy.

Deno + SvelteKit + Paraglide | Can not run dev server using deno because of "FsWatcher"
Hey there everyone :hooray_deno:
I have been trying out Deno for my SvelteKit projects and enjoying it so far. However, I ran into an issue when using Paraglide.
While running the development server, I keep encountering this error:
...
error: module 'node:fs' does not provide an export named 'globSync'
Documentation (https://docs.deno.com/api/node/fs/~/globSync) says:
import { globSync } from "node:fs";
But that just doesn't work....
`npm workspace`'s support with Deno v2
I am trying to follow the tutorial of using Deno Workspaces w/ npm workspaces https://docs.deno.com/runtime/fundamentals/workspaces/#migrating-from-npm-workspaces
If I copy all the code and then run
deno check main.ts, I get the following error:
```...Typescript monorepo LSP performance
I recently converted a node and typescript monorepo to deno as an experiment to try out the monorepo support in deno. To my disappointment i noticed a severe slowdown in LSP performance in vscode with the deno extension for a medium sized monorepo (~15 packages, tens of thousands of lines of code, and LSP response times went from from a barely noticeable fraction of a second to a consistent 3-5 seconds delay)
This got me wondering, how does deno actually instrument the LSP for monorepos? Does it use one or several typescript projects under the hood, does it use project references?
My guess would be that deno just makes one typescript project, instead of one per package in the monorepo. At least that would explain the huge difference in performance compared to using multiple node and tsc based packages with project references....

Reliable pattern for cleaning up resources as process exists?
I'm using Explicit Resource Management (I'm familiar with (never mind, unload doesn't fire during SIGINT)
I also know about
await using resource = ...), but [Symbol.asyncDispose] doesn't get called if my program is killed with SIGINT or other signals. Is there a known/good pattern for making sure some resource gets cleaned up, even if the process is dying?
window.onunload, but since that's a global, it feels unreliable to rely on, since anything else in my dependencies might overwrite it during a lengthy runtime. I may also have more than one thing that I want to clean up.Deno.addSignalListener() but there are an awful lot of signals I'd need to listen to....Deno cannot use ErrorEvent Type from @types/ws
The Error:
deno.json:...
Cannot import type declaration files. Consider importing 'ws' instead of '@types/ws'.
import type { ErrorEvent } from "@types/ws";
Cannot import type declaration files. Consider importing 'ws' instead of '@types/ws'.

Why are both denols and tsserver attaching to the same TypeScript project in Neovim?

deno 2.1.5 not running in Azure Container App environment
I was using
FROM denoland/deno:latest in my Dockerfile and after the deno 2.1.5 release new replicas want deploy to CA environments, the container starts but immediately terminates.
Tried pulling the deployed image locally and it runs on my Windows PC on docker desktop without any issues.
I fixed the image to FROM denoland/deno:2.1.4 which solves the issue on Azure CA environment but think there might be some underlying compatibility issues....How can I add tailwindcss to a deno/vite/solidjs project?
Saw this article: https://deno.com/blog/build-solidjs-with-deno, but I want to add tailwindcss to this configuration. I tried this article from tailwind; https://tailwindcss.com/docs/guides/vite. But when i apply tailwind classes to any html elements it does nothing.
Expose package scripts
Hey, I'd like to run a script which is in one of installed packages. Something like (fake syntax)
deno amazingFramework list. Where list is the script and amazingFramework is name of package. Node deals with that with bin in package.json and .bin directory.
Is it possible to do similar thing in deno?...Start Data Science Channel
I think Deno with Jupyter has a lot of potential to drive data science. To promote its adoption and sharing of ideas, I propose that we create a dedicated channel for this topic. Please let me know if you agree, and if so, what the next steps should be. Thanks
