Referencing environment variables from .env in deno compile or deno task commands

This works for me on Linux: deno.json

{
  "tasks": {
    "print-env": "deno run -A --env-file print-env.ts"
  }
}

{
  "tasks": {
    "print-env": "deno run -A --env-file print-env.ts"
  }
}

.env

MY_VAR="THIS IS MY VAR"

MY_VAR="THIS IS MY VAR"

print-env.ts

console.log(Deno.env.get('MY_VAR'))

console.log(Deno.env.get('MY_VAR'))

$ deno task print-env
Task print-env deno run -A --env-file print-env.ts
THIS IS MY VAR

$ deno task print-env
Task print-env deno run -A --env-file print-env.ts
THIS IS MY VAR

[VSCodium] - Deno task list

It can't load tasks even if you create an empty folder and just put a deno.json inside?

Stubbing @std/x

What you're trying to do is to mock a module's function, which is not supported. Try this workaround:

import * as stdYaml from 'jsr:@std/yaml';

 using _parse = stub(
    {parse: stdYaml.parse},
    'parse',
    returnsNext([{ version: '3.8' }]),
  );

import * as stdYaml from 'jsr:@std/yaml';

 using _parse = stub(
    {parse: stdYaml.parse},
    'parse',
    returnsNext([{ version: '3.8' }]),
  );

Deno and Eta browser-side?

Are you sure Eta works in the browser? I would guess it doesn't. But if it does, the maintainers might provide a bundle

unable to see documentation on deno.land/x

You can still generate the docs locally First download the package:

deno cache --vendor https://deno.land/x/jose@v5.9.6/index.ts

deno cache --vendor https://deno.land/x/jose@v5.9.6/index.ts

It will be downloaded to a folder called vendor Then generate the docs for it:

deno doc --html --name="jose" ./vendor/deno.land/x/jose@v5.9.6/index.ts

deno doc --html --name="jose" ./vendor/deno.land/x/jose@v5.9.6/index.ts

Docs will be generated in a folder called docs by default. Open the file docs/index.html in your browser to navigate through the docs

batching tasks

Something like this (untested):

import { chunk } from "jsr:@std/collections/chunk";

for (const spinGroup of chunk(...data, 100)) {
  const spins = spinGroup.map((spin) => this.processSpin(spin));
  await Promise.all(spins);
}

import { chunk } from "jsr:@std/collections/chunk";

for (const spinGroup of chunk(...data, 100)) {
  const spins = spinGroup.map((spin) => this.processSpin(spin));
  await Promise.all(spins);
}

Deno needs better memory leaks debugging tools

I have double checked all of my code to find any clue, but nothing found!

Have you checked inside your dependencies as well?

I am writing this to know if there are any tools that I can use with Deno to debug this issue?

I know that Deno.test() is able to detect some leaks.

Is there any plan to develop some more lower-level tools that can allow debugging these kind of anonymous memory leaks?

AFAIK, no.

deno on alpine-linux

I just realized you did add to Path. I guess $HOME is not resolving to the right directory. Maybe you should instead add /root/.deno/bin to PATH

deno on alpine-linux

Try to log out and then log in again If that doesnt work, I guess deno didnt get added to PATH You can either add deno to PATH manually or call the executable with the full path: /root/.deno/bin/deno

Reliable pattern for cleaning up resources as process exists?

Interesting. Maybe this question is worth opening an issue. I wonder if it would be possible for the Deno runtime itself to automatically cleanup resources declared with using. Not sure if that could work, whether Deno would know the order to cleanup each using

deno 2.1.5 not running in Azure Container App environment

No worries. I was just wondering if the "problem" was in the Deno runtime itself or in your code. Wondering if the app was just one line - a simple console.log, or a Deno.serve() - it would work or not. The guys are implementing Otel, maybe it has something to do with the problem, IDK

std JSON serializer/deserializer with Set and Map support

There is some builtin serialization because KV supports Map and Set, but I dont think it's exposed to users: https://docs.deno.com/deploy/kv/manual/key_space/#values
