How to set as external all node modules in rollup?

I want to have all modules imported from node_modules as external. What is the configuration for this?

I tried without success :

import path from "path";
import glob from "glob";
import multiEntry from "rollup-plugin-multi-entry";

export default {
    entry: "src/**/*.js",
    format: "cjs",
    plugins: [
        multiEntry()
    ],
    external: glob.sync("node_modules/**/*.js").map(file => path.resolve(file)),
    dest: "dist/bundle.js"
}];

or

import multiEntry from "rollup-plugin-multi-entry";

export default {
    entry: "src/**/*.js",
    format: "cjs",
    plugins: [
        multiEntry()
    ],
    external: id => id.indexOf("node_modules") !== -1,
    dest: "dist/bundle.js"
}];
rollup node.js module

Using rollup 2.63 this works for me

export default {
    // ...
    external: [/node_modules/],
    // ...
}

UPDATE:

Use rollup-plugin-auto-external.

Thank @IsidroTorregrosa for his answer (and @maxkueng ofcourse). I improved it by adding node built-in modules (like fs and path) and also peerDependencies. Use:

import builtins from 'builtin-modules/static'
const pkg = require('./package.json')
// ...
export default {
    external: builtins.concat(Object.keys(pkg.dependencies || {})).concat(Object.keys(pkg.peerDependencies || {})),
    // ...
}

See builtin-modules on npmjs.com and also see:

export default {
  ...
  external: [...Object.keys(pkg.dependencies), /^node:/]
}
