What is the Deno equivalent of process.argv in Node.js? - deno

Question

When working with NodeJS, I can pass the arguments to a Node script like this:
$ node node-server.js arg1 arg2=arg2-val arg3
And can get the arguments like so:
// print process.argv
process.argv.forEach(function (val, index, array) {
console.log(index + ': ' + val);
});
//Output
0: node
1: /Users/umar/work/node/node-server.js
2: arg1
3: arg2=arg2-val
4: arg3
How to get the command-line arguments in Deno?
Some experts suggested me to solve the problem by answers to the question

Answer 1

Deno executable path ~ process.argv[0]:
Deno.execPath()
File URL of executed script ~ process.argv[1]:
Deno.mainModule
You can use path.fromFileUrl for conversions of URL to path string:
import { fromFileUrl } from "https://deno.land/std#0.55.0/path/mod.ts";
const modPath = fromFileUrl(import.meta.url)
Command-line arguments ~ process.argv.slice(2):
Deno.args
Example
deno run --allow-read test.ts -foo -bar=baz 42
Sample output (Windows):
Deno.execPath(): <scoop path>\apps\deno\current\deno.exe
import.meta.url: file:///C:/path/to/project/test.ts
as path: C:\path\to\project\test.ts
Deno.args: [ "-foo", "-bar=baz", "42" ]

Answer 2

To get your script’s CLI arguments in Deno, just use Deno.args:
> deno run ./code.ts foo bar
console.log(Deno.args); // ['foo', 'bar']
If you need something identical to Node's process.argv for compatibility reasons, use the official 'node' shim:
import process from 'https://deno.land/std#0.120.0/node/process.ts'
console.log(process.argv); // ['/path/to/deno', '/path/to/code.ts', 'foo', 'bar']
For illustrative purposes, if you wanted to manually construct a process.argv-style array (without using the official 'node' shim) you could do this:
import { fromFileUrl } from "https://deno.land/std#0.120.0/path/mod.ts";
const argv = [
Deno.execPath(),
fromFileUrl(Deno.mainModule),
...Deno.args,
]
console.log(argv); // ['/path/to/deno', '/path/to/code.ts', 'foo', 'bar']
