Issues with importing from npm - should I switch to esm.sh?

Is importing from esm.sh recommended over npm? Recently I've been having a lot of issues with imports from npm inside Jupyter. For example: ``` import * as crypto from "node:crypto"; import { DynamoDB } from "npm:@aws-sdk/client-dynamodb@3.714.0";...

Nextjs. task dev

so unsure what's going on here but I've cloned my git project to my work macbook but whenever I use deno task dev with nextjs it gives me this error

Leaks Detected

Hey guys - got a couple of blocks of tests that are flagging detected leaks. It would be awesome if we could get more details on these detections. I understand from past issues there are challenges to do with the layers that Deno tests are built on. So this is a bit of a hail-Mary in case someone can guide me as to how to track down a leaked file....

Wierd issue with uncaught exception in WebSocketPovider on Canary

On stable the error listener block is executed but in canary (which I have been using as a fix to "Warning: Not implemented: ClientRequest.options.createConnection") the error doesn't seem to propogated to the listener and thus the rest of my code, instead an uncaught error is thrown, which is messing up my tests since I am expecting this error event to be thrown.

Issues migrating dependencies from v1.x to v2.x

Hey, I'm facing some issues when upgrading from v1.146 to v2. We have a backend monorepo that uses import_map.json files to manage dependencies per sub module in our monorepo. We don't have a package.json for Deno (only for our Next.js frontend which is still on node). We do have a deno.jsonc at the root level of our project. After upgrading to Deno v2, we get these errors when we run or try to install: ```sh install...
