I 'm trying to debug a Deno project, but I dont know, how to debug this on Windows 10 using the lldb debugger as the documentation says.

The LLDB, on windows 10 seems to be not so easy to install.

///reference path="../../deno.d.ts"
import * as deno from 'deno';
import { color } from 'https://deno.land/x/colors/main.ts';

const s = new Set();
[*] s.add('test')

console.log(s);

[*] <-- a breakpoint

deno

In order to debug with Deno:

  1. Add somewhere in your code a debugger; line of code.
  2. Run with --inspect-brk flag. deno run --inspect-brk ... or deno test --inspect-brk ... to debug tests.
  3. Open chrome://inspect page on Chrome.
  4. On the Remote Target section press to "inspect".
  5. Press the Resume script execution button, the code will pause just in your breakpoint.

If you use VSCode here is a launch.json I am using.

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug Deno",
      "type": "node",
      "request": "launch",
      "cwd": "${workspaceFolder}",
      "runtimeExecutable": "deno",
      "runtimeArgs": ["run", "-A", "--inspect-brk", "index.ts"],
      "port": 9229
    }
  ]
}
