Async execution context

Is there any way I can create a global that is unique to an async operation? I would like to use that for logging operation context. Or maybe just a built in way to get some kind ID of the current operation, as in for each task in the event loop getting a different ID, than I can use regular module context with the ID.

Error Deploying to Deno Deploy LODASH isEmpty.js

I am having issues deploying to deno deploy. All was well 3 days ago. Made some changes today - but not in terms of adding/deleting libraries. Today I am getting this error: "Error The deployment failed: HTTP status client error (404 Not Found) for url (https://raw.githubusercontent.com/lodash/lodash/master/isEmpty.js)" Appreciate anyone's help here!

Is there anywhere I could find documentation / examples on how to use deno_core / deno_runtime

I'd like to use deno_core / deno_runtime to safely execute some arbitrary javascript code from a rust program that'll be received from a user, I can't really find any clear examples of exactly how to do this, was wondering if anyone had any examples / guides in the best way to approach this

API architecture for generic callback

Hi there,
I have a general question about code architecture for an API I'm doing.
Basically, it listens to MIDI messages from a native library and I use an FFI binding to forward the messages to the user. A message is represented by an array of bytes, and from that you can describe its data and how to interpret it. I made a layer that converts the raw data to a typed object, but what I want to do is offer a choice to the user so he can retrieve either the raw data or the converted typed object....

How can I run `deno test` on all `*.spec.ts` files contains in a specific directory ?

Everything is in the question, it seems very strange that we do not have a pattern option to specify we wanna run all test contains in a directory

Basic react server side rendering does not work on Deno Deploy but does locally

node crypto

Hey everyone, can you explain why certain packages such as node/crypto are not included in newer versions? I noticed that it is available in version 0.169.0 on this link (https://deno.land/std@0.169.0/node/crypto.ts), but returns a 404 error in version 0.201.0 (https://deno.land/std@0.201.0/node/crypto.ts). What's the reason behind this?

Pretty new to Deno, what is the recommended way to create a monorepo-like in Deno ?

Everything is in the question. I tried during the entire week-end to get up & running with monorepo-like setup in Deno.

My NodeJS monorepo was pretty simplistic:
- app
---- 3 projects inside (front, server, and cli)
- packages
---- 1 project inside which is used by all 3 mentioned above

I don't have any problem with Deno runtime project (eg. CLI, server, etc), Deno delivers perfectly (it's a real pleasure to work with it on those type of project).

**The real pain reside in FrontEnd with V...

Autosave firing on editing `.ts` files when a separate Deno enabled project is open

Hello, I am working on slack automation using deno.
I'm developing with webstorm, but I'm having a problem because the .ts file is automatically saved in the deno project, is there a solution?

UUID of managed KV database

Hello, I am trying to follow [this doc](https://docs.deno.com/kv/manual/on_deploy#connect-to-managed-databases-from-outside-of-deno-deploy) to connect a Deno KV from an application running elsewhere (not Deno Deploy). I don't know where to find the database uuid. Is there something I am missing? Is it even possible to access KV from outside Deno Deploy?

Setting source map root with `deno_emit`

Hello! I'm currently trying to use deno_emit so bundle some assets. The code bundles properly, however the source map is using the absolute path to files on my drive. I'd prefer if it just used relative paths, is that possible? No worries if not :) thanks!

In Deno, what is the best way to simply host static websites?

What is the best way to simply host static/cached files?
Without having to do a read file call every request.
And would this work with Deno Deploy?
