Trying to deploy fresh project to deno, and all the JS has 500 errors
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.
I've tried following this guide from deno but cant get it to work. i filed [a bug report with reproduction steps on the deploy_feedback github here....
How Node.js SQLite works on Deno?
Hello, I'm curious how node:sqlite is supported in Deno? Basically you reflect the APIs exposed by Node.js? Or you get/fetch the code from Node.js and compile it to Deno? Because there are open issues in Node.js for SQLite and thought if those will be reflected in Deno once Node.js deploys them.
How to create private packages in deno and not fall into ERR_UNSUPPORTED_NODE_MODULES_TYPE_STRIPPING
Hi everyone! Maybe someone already solved this problem, but I could not find any information or "how to" guide, ChatGPT did not help as well.
The problem:
I have few private repositories in gitlab, all uses deno as runtime, I want to share some duplicated typscript code written in deno (i.e. all imports ends with .ts extension, also present libraries like "jsr:@std/testing/bdd"; ) so it cant just be launched with node. Have decided to move shared code to separate repository and make a npm package from it (keyword is npm here).
