listen-in v1.0.2

listen-in

listen-in is a simple to use, Promise based, STDIN listener for node applications

Motivation

listen-in was written because I wanted a way to pass secure information into Node applications with out adding EXPORT or configuration files to my user profile.

Options

• envToken [String]: add value to process.env under this name. (default null)
• message [String]: Message to prompt user with. (default null)
• insecure [Boolean]: Passes user input into the then.

Basic Use

const lstn = require('listen-in');

lstn({
  message: 'First Name: ',
  insecure: true
})
.then(data => {
  console.log(`First Name: ${data}`);
});

Use with es2017 Async/Await

import lstn from 'listen-in';

const config = async () => ({
  dbName: 'production',
  dbUser: 'username',
  dbPassword: await lstn({ insecure: true, message: 'Database Password: ' })
});

Use for updating process.env:

import lstn from 'listen-in';

function getConfigs() {
  return lstn({ message: 'Database Password: ', envToken: 'dbp'})
  .then(() => ({
    dbName: 'production',
    dbUser: 'username',
    dbPassword: process.env.dbp
  }));
}
