npm:@triton-one/yellowstone-grpc4: "This expression is not constructable"
Hey all,
I'm attempting to import a class from a default export named "Client" from this npm package named "@triton-one/yellowstone-grpc4", however trying to construct it gives an error saying it's not constructable. Checking the type definition file, the class looks like it's being exported properly, and does contain a constructor. Here's a minimal example to reproduce the issue:

Firebase: broken pipe when using npm
Hi, I've been playing around with Deno and Firebase/Firestore, put together a short script:

Type sharing between Deno server and Expo app not working
Hi all! 👋
I'm trying to share tRPC types between a Deno server and an Expo React Native app in a monorepo. My Deno server exports a fully-typed AppRouter for its tRPC routes, and I want the Expo client to import that type directly so that any changes in the backend are immediately reflected in the client's type checking. However, while everything works at runtime, TypeScript in the Expo client resolves the imported AppRouter as any, which means I'm not catching type errors as expected.
I really wanted to give Deno a try, but if I can't resolve this issue, I might have to consider migrating to Node. Has anyone encountered this problem or found a workaround?...

How to inspect Deno's rare uncaught rejections?
I'm encountering an AbortError with Deno.serve, but it's difficult to report the issue since I can't reliably reproduce it. Based on the stack trace, I can't seem to catch the error, as there’s no clear interception point.
How can I investigate and debug this?

Brand new fresh based project which works fine locally. Published to Deploy and no errors - home page loads fine but none of the JS loads... all of it has a 500 in the network tab and if I try open the JS directly I get "An error occurred during route handling or page rendering."
Nothing in the deploy logs either... but stuck on what to try next...
How to build/cache deno program ahead of time
Hey folks! New Deno user here, really loving it so far!
I've built a service that involves a Worker. The Worker is reponsible for executing some provided code. The Worker is terminated after a timeout if it's taking too long. I have a problem that the Worker always takes too long on the first execution of the program – both right after it's been deployed, or locally when running the test suite. In subsequent executions it's as fast as you'd expect.
How can I cache the program ahead of time? I thought thats what
deno cache does, as its help string says "Download and compile a module with all of its static dependencies and save them in the local cache, without running any code", but its docs link (https://docs.deno.com/go/cache) redirects to the docs for deno install , and running deno cache on my src/main.ts and src/worker.ts doesn't have any effect on the problem I'm having....how to install and use framer motion in fresh js

Deno `fetch()` SSRF prevention: Best practices for user-supplied URLs?
What are the best practices for preventing SSRF vulnerabilities when using the
fetch() API in Deno, especially when the input URL for fetch() needs to be arbitrarily received from users?
I understand that using a whitelist for allowed hosts is a good starting point, but I'm looking for a more comprehensive approach. Are there any specific Deno APIs or techniques to effectively block internal IP addresses, limit URL schemes, prevent DNS rebinding attacks, or handle redirects securely? Any example code snippets would be greatly appreciated!...Deno in Jupyter Notebook: Run cells with --check
I would like to be able to run cells with
--check enabled, like you would with a file deno run --check file.ts. Currently, running cells in Jupyter notebook with the Deno kernel will not check types and will succeed even if there are type errors, just how the default behaviour of deno run is to not check types. I would like cells with type errors to fail when I run them. Is there any way to do this? Thanks!Deno permissions and security
Hello
I see that deno provides allow net and filesystem - how can i restrict these things based on the file and not blanket on the sandbox? I.e. i have my code and user code - i want to restrict user code but allow my code to have access - user code may use apis defined in my code...

Is there a way to handle permission prompts from a worker?
I would like to give a worker net/import access to any public IP over https, without giving it the ability to bind to any address or access private IP addresses. The docstring for the
net property on the deno.permissions worker option says if set to string[], the net permission will be requested with the specified host strings with the format "<host>[:<port>].", and hooking that seems like the easiest way to do this kind of permission filtering logic, but I can't figure out how to.high memory usage using compiled binary in docker

hi there 👋
one of deno's main selling points over choosing another runtime like bun is that it promises next.js compatibility, but i haven't yet been able to build and deploy a next.js app with deno.
