Hacking around scripts

• Multiple Dangerfile: yarn danger --help
• yarn vs npm - am sorta preferring yarn now due to executing.
• How to store env variables in a repo? Should we store env variables in a repo?
• exec to run shell commands from node.
• const args = require('yargs').argv then args._[0] to access the argument.

• require('fs') to use file system.

• Exit in Node: Reference is process.exit(1).
• console.log can be in two arguments to add a color.
• Reading files in Node: Reference
• Environment variables? Reference
  • Can set it manually via process.env.
• Appending to a file: Reference

const { exec } = require('child_process');
const args = require('yargs').argv;
const fs = require('fs');

const tenant = args._[0];

const getTenants = function () {
  return new Promise((resolve, reject) => {
    exec(
      `ls  ./projects | xargs`,
      (error, stdout, stderr) => {
        console.log('haha');
        resolve(stdout.trim());
      },
    );
  });
};
