[Poi] Use Poi to Build an Index.js with Modern JavaScript Features

Poi can easily launch an

import

it right away.

Install:

npm install -g poi

Code:

// src/index.js

import {Observable} from 'rxjs';

Observable.intervable(1000).subscribe(
i = > document.getElementById("app").innerHTML = `
<h1>{i}</h1>
`
)

Run:

poi src/index --port 3000
