CLI REPL with Deno

You can use std/io to build a REPL.

import { readLines } from "https://deno.land/[email protected]/io/bufio.ts";


async function read() {
   // Listen to stdin input, once a new line is entered return
   for await(const line of readLines(Deno.stdin)) {
      console.log('Received', line)
      return line;
   }
}

console.log('Start typing');
while(true) {
        await read()
}

You can build from here, process each line, add commands and so on.
