Hoping for a clean way to get an array of filenames in directory

You can use <Array>.fromAsync

const result = (await Array.fromAsync(Deno.readDir(Deno.cwd()))).filter(({ isFile }) => isFile);

const result = (await Array.fromAsync(Deno.readDir(Deno.cwd()))).filter(({ isFile }) => isFile);

Or go over the board with fp-ts, which is way more readable

import { task, function as func } from "npm:fp-ts"

const result = await func.pipe(
  Deno.cwd(),
  Deno.readDir,
  Array.fromAsync,
  task.of,
  task.map((files) => files.filter(({ isFile }) => isFile)),
  (fn) => fn()
)

import { task, function as func } from "npm:fp-ts"

const result = await func.pipe(
  Deno.cwd(),
  Deno.readDir,
  Array.fromAsync,
  task.of,
  task.map((files) => files.filter(({ isFile }) => isFile)),
  (fn) => fn()
)

Deno, TypeScript, ESBuild, WebGL, VSCode

You cannot do imports like that. The reason for which you do the declare module … is because under the hood, a bundler like webpack or rollup is used. Deno doesn't have those. One alternative is to just use Deno.readFile and the like

Is there any way to run deno as a cluster on one machine? (like pm2)

Create an ecosystem.config.js file and add the following contents:

// change for your values
module.exports = {
  apps: [
    {
      name: "name",
      script: "/path/to/source.ts",
      interpreter: "/home/user/.deno/bin/deno",
      interpreterArgs: "run -A --unstable",
    },
  ],
};

// change for your values
module.exports = {
  apps: [
    {
      name: "name",
      script: "/path/to/source.ts",
      interpreter: "/home/user/.deno/bin/deno",
      interpreterArgs: "run -A --unstable",
    },
  ],
};

Then run

npx pm2 start ecosystem.config.js

npx pm2 start ecosystem.config.js

you cant use Deno.* there. Either a call to an api in the routes/api/ folder, or a handler in that route

Inquiry Regarding Deno Security Model and Command Injection Vulnerability

Well yes and no. If the user controls the command executed, yes. It’s the same as —allow-ffi. If you grant that, FFI can be used, essentially overcoming all sandbox features

Inquiry Regarding Deno Security Model and Command Injection Vulnerability

You should also sanitize the user input, interpolating a script and executing whatever was fed into is not the way to go <:cookie_deno:1002977285734932480>

Inquiry Regarding Deno Security Model and Command Injection Vulnerability

I do not fully understand your question. By running deno with --allow-net and --allow-run you're giving explicit permision for deno to access all network features and run commands. You can narrow down these permissions by using the following syntax: --allow-read=.env,main.bin
