import { createInterface } from "https://deno.land/std@0.145.0/node/readline.ts";
The readline.createInterface()
method creates a new readline.Interface
instance.
const readline = require('readline');
const rl = readline.createInterface({
input: process.stdin,
output: process.stdout
});
Once the readline.Interface
instance is created, the most common case is to
listen for the 'line'
event:
rl.on('line', (line) => {
console.log(`Received: ${line}`);
});
If terminal
is true
for this instance then the output
stream will get
the best compatibility if it defines an output.columns
property and emits
a 'resize'
event on the output
if or when the columns ever change
(process.stdout
does this automatically when it is a TTY).
When creating a readline.Interface
using stdin
as input, the program
will not terminate until it receives EOF
(Ctrl+D on
Linux/macOS, Ctrl+Z followed by Return on
Windows).
If you want your application to exit without waiting for user input, you can unref()
the standard input stream:
process.stdin.unref();
