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

Posted 2020-10-19 Answer1215

Poi can easily launch an index.js file simply by running the poi command. This will launch a dev-server and automatically reload whenever you make changes. You can also npm install any package you need and 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
