help

in Deno

Threads

I've been trying different ways to use my personal access token (ddp_...) to access Deno Deploy's KV databases with no luck. It seems browsing them via web is not an option?

I've placed them in my .env file
The variables are accessible
I've even tried with a manual curl post only to receive the same message.

Is this a bug? Am I missing something? I can't find documentation on this.

Thanks!

Map */ to */index.ts?

jcayzac12/13/25, 4:27 AM

With import maps, is it possible to map any import path ending with

to the same path +

index.ts

index.ts

?
Since import maps, unlike

compilerOptions.paths

compilerOptions.paths

, don't accept

placeholders, I guess not?

cannot find env

grontylion12/12/25, 9:12 AM

I have three branches: the main branch is the master branch, and there are also dev and autumn branches. I have set environment variables, and the context is set to "Preview" (the other options are Production, Build, Local). However, when I build on the dev or autumn branches, I always get errors saying the environment variables cannot be found.

definition for subtle crypto broken?

jcayzac12/12/25, 8:53 AM

This code fails when I type-check because

crypto.subtle.digest

crypto.subtle.digest

expects a

BufferSource

BufferSource

as 2nd param, contradicting all the docs and all the examples out there:

async function digest(data: Uint8Array): Promise<string> {
    return Array.from(new Uint8Array(await crypto.subtle.digest('SHA-256', data)))
        .map((b) => b.toString(16).padStart(2, '0'))
        .join('')
}

async function digest(data: Uint8Array): Promise<string> {
    return Array.from(new Uint8Array(await crypto.subtle.digest('SHA-256', data)))
        .map((b) => b.toString(16).padStart(2, '0'))
        .join('')
}

There's nothing wrong with the code and it works just fine, but to pass typechecking I have to cast to

any

and silence that, which isn't great

Are Deno Workers still too insecure for code isolation?

Anders12/10/25, 2:25 PM

Does anybody know if Deno Workers are still too insecure as an architecture to run untrusted user code?
The Val Town team has written som great articles over the years about the different iterations of their architecture. I'm wondering if Deno's sandboxing is still too weak, as mentioned in https://blog.val.town/blog/val-town-newsletter-5/

WebStorm not recognising deno.json import map

jsdom 27 wants to read the filesystem

I'm trying to update

return value setTimeout and Deno.unrefTimer

fast&fear< 🔥12/4/25, 3:56 PM

Hi,

In the recent version, I had no trouble passing the return value from setTimeout to Deno.unrefTimer.
But today I get this:

TypeError: expected f64
 ❯ Object.unrefTimer ext:core/01_core.js:810:25
 ❯ Object.unrefTimer ext:deno_web/02_timers.js:123:8
 ❯ ResolveOnce.setProcessed src/resolve-once.ts:627:20

TypeError: expected f64

 ❯ Object.unrefTimer ext:deno_web/02_timers.js:123:8
 ❯ ResolveOnce.setProcessed src/resolve-once.ts:627:20

and some logs later:

ResolveOnce set a reset timer for Timeout {
  _idleTimeout: 10,
  _onTimeout: [Function (anonymous)],
  _timerArgs: [],
  _isRepeat: false,
  _destroyed: false,
  [Symbol(refed)]: true,
  [Symbol(timerId)]: 202
} on { deno: '2.5.6', v8: '14.0.365.5-rusty', typescript: '5.9.2' }

  [Symbol(timerId)]: 202
} on { deno: '2.5.6', v8: '14.0.365.5-rusty', typescript: '5.9.2' }

Why does setTimeout return a structure, and unrefTime might look for a value in [Symbol(timerId)]?

Did I miss something, or is that an error?

There is something strange going on. I tried to make it work, and need this code, which means there are some cases where the returned value is a number, and sometimes it's the struct:

Deno.unrefTimer timerId from struct: 236 version: { deno: '2.5.6', v8: '14.0.365.5-rusty', typescript: '5.9.2' }

Test Case Names Disappearing?

James12/1/25, 11:28 PM

Has anyone else run into this? Some of my test case names disappear:

running 15 tests from ./tests/config_test.js
Configuration can be loaded from options only ... ok (19ms)
 ok (8ms)
Configuration options take precedence over data object ... ok (4ms)
 ok (6ms)
Configuration has data object data ... ok (2ms)

running 15 tests from ./tests/config_test.js
Configuration can be loaded from options only ... ok (19ms)
 ok (8ms)
Configuration options take precedence over data object ... ok (4ms)
 ok (6ms)
Configuration has data object data ... ok (2ms)

The lines starting with "ok" are individual test cases with names. But the names don't show up... It is always the same test cases too, regardless of where I place them. Here is an example of the first two test cases, the first appears, the second doesn't:

Deno.test({
    name: "Configuration can be loaded from options only",
    fn: async () => {
        const config = await Config.load(defaultOptions, undefined);
        assertEquals(config.src, "mySrc");
        assertEquals(config.templates, "myTemplates");
        assertEquals(config.out, "myOut");
        assertFalse(config.isDev);
        assertFalse(config.isDebug);
    },
});

Deno.test({
    name: "Configuration can be loaded from data object only",
    fn: async () => {
        const config = await Config.load({}, dataFilePath("defaultData.js"));
        assertEquals(dataRelativePath(config.src), "myDataSrc");
        assertEquals(dataRelativePath(config.templates), "myDataTemplates");
        assertEquals(dataRelativePath(config.out), "myDataOut");
        assertFalse(config.isDev);
        assertFalse(config.isDebug);
    },
});

Deno.test({
    name: "Configuration can be loaded from options only",
    fn: async () => {
        const config = await Config.load(defaultOptions, undefined);
        assertEquals(config.src, "mySrc");
        assertEquals(config.templates, "myTemplates");
        assertEquals(config.out, "myOut");
        assertFalse(config.isDev);
        assertFalse(config.isDebug);
    },
});

Deno.test({
    name: "Configuration can be loaded from data object only",
    fn: async () => {
        const config = await Config.load({}, dataFilePath("defaultData.js"));
        assertEquals(dataRelativePath(config.src), "myDataSrc");
        assertEquals(dataRelativePath(config.templates), "myDataTemplates");
        assertEquals(dataRelativePath(config.out), "myDataOut");
        assertFalse(config.isDev);
        assertFalse(config.isDebug);
    },
});

I can't see any obvious differences between them, but maybe I'm just missing something obvious.

Accessing the `Deno.lint` namespace for Intellisense

tym12/1/25, 6:00 PM

Hello,

I have been trying to author a Deno.lint plugin following the guide. However, I can't get VSCode to recognize the namespace to get Intellisense to work.

I just get the error:

Namespace 'Deno' has no exported member 'lint'.deno-ts(2694)

Namespace 'Deno' has no exported member 'lint'.deno-ts(2694)

I know that the API is labeled

, I have enabled

and tried

but to no avail.

Does anyone know how to do this?

Test Case Names Disappearing?

James12/1/25, 11:28 PM

Has anyone else run into this? Some of my test case names disappear:

running 15 tests from ./tests/config_test.js
Configuration can be loaded from options only ... ok (19ms)
 ok (8ms)
Configuration options take precedence over data object ... ok (4ms)
 ok (6ms)
Configuration has data object data ... ok (2ms)

I can't see any obvious differences between them, but maybe I'm just missing something obvious.

Accessing the `Deno.lint` namespace for Intellisense

tym12/1/25, 6:00 PM

Hello,

I have been trying to author a Deno.lint plugin following the guide. However, I can't get VSCode to recognize the namespace to get Intellisense to work.

I just get the error:

Namespace 'Deno' has no exported member 'lint'.deno-ts(2694)

Namespace 'Deno' has no exported member 'lint'.deno-ts(2694)

I know that the API is labeled

unstable

unstable

, I have enabled

deno.lint

deno.lint

and tried

deno.unstable = true

deno.unstable = true

.vscode/settings.json

.vscode/settings.json

but to no avail.

Does anyone know how to do this?

Testing fails for temporal in deno environment

Albion12/1/25, 3:19 PM

import { TestWorkflowEnvironment } from "@temporalio/testing";

    beforeEach(async () => {
      testEnv = await TestWorkflowEnvironment.createTimeSkipping();
    });
    afterEach(async () => {
      restore();
      await testEnv?.teardown();
    });

    it.only('say hi', () => {
      console.log('hello')

import { TestWorkflowEnvironment } from "@temporalio/testing";

    beforeEach(async () => {
      testEnv = await TestWorkflowEnvironment.createTimeSkipping();
    });
    afterEach(async () => {
      restore();
      await testEnv?.teardown();
    });

    it.only('say hi', () => {
      console.log('hello')
    })

I have this test for temporal, it currently fails with this message:

say hi => https://jsr.io/@std/testing/1.0.16/_test_suite.ts:171:39
error: Error: Failed to connect before the deadline

say hi => https://jsr.io/@std/testing/1.0.16/_test_suite.ts:171:39
error: Error: Failed to connect before the deadline

Is there perhaps any solution for this or workaround? Thanks
