AWS Select profile

This is a helper to switch AWS profiles, which then can be used by other scripts.

The script parses the ~/.aws/config file and let's the user select one of the configured profiles. The current active profile is marked with a star.

The selected value then will be stored as AWS_PROFILE in the env file.

To use the profile name in another script, you can get the value via:

const region = await env('AWS_PROFILE');

// Menu: AWS Select Profile
// Description: Select AWS profile from you AWS config

import { readFileSync } from 'fs';

const ini = await npm('ini');
const awsConf = `${process.env.HOME}/.aws/config`;

const config = ini.parse(readFileSync(awsConf, 'utf-8'));

const currentMarker = ' ★';
const currentProfile = env['AWS_PROFILE'];

const sections = Object.keys(config).reduce(function (filtered, section) {
  if (section.startsWith('profile ')) {
    let profileName = section.replace('profile ', '');
    if (profileName == currentProfile) {
      profileName += currentMarker;
    }
    filtered.push(profileName);
  }
  return filtered;
}, []);

const profile = await arg(
  {
    placeholder: 'Select profile',
    hint: `parsed from ${awsConf}`,
  },
  sections.sort()
);
await cli('set-env-var', 'AWS_PROFILE', profile.replace(currentMarker, ''));
