What's an Effective Engineer?

Recently I ran into a problem in React Native.

I wanted to be able to have more granular control of my build besides React Native's __DEV__.

Our QA people need to have a few tools at their disposal to run the APP vs our live and test servers. I don't want to make them download the project on Github and run it. That would force them onto a mac for iOS builds. I don't want to ship the app with __DEV__ on. It would be quite complex to have them connect to some dev package server to run the app A third option was needed. There should be a __QA__ flag. This way I can release the APP in without __DEV__ but keep some QA features I want. The naive way would be to have something like a globals.js file that you include and edit the file for different releases. eg.

	#!/bin/bash

	# Invoke like this:
	# ./watch.sh my command here
	# And it will run 'my command here' once, and then when it detects changes.

	# TODO: Don't just search in the last second. Search for updates since the last
	# completed build. Otherwise for big directories, midway through your search
	# you've already taken 1s and you will miss updates.

	// @flow

	import React from 'react';
	import { StatusBar } from 'react-native';
	import hoistStatics from 'hoist-non-react-statics';
	import invariant from 'invariant';
	import { withNavigation } from 'react-navigation';

	import type { Subscription } from '../../types';

	type copyOpts;

	[@bs.obj] external makeCopyOpts : (~overwrite: bool=?, ~errorOnExist: bool=?, ~dereference: bool=?, ~preserveTimestamps: bool=?, ~filter: (string=>bool)=?, unit) => copyOpts = "";

	/* copySync(src, dest, [options]) */
	/* https://github.com/jprichardson/node-fs-extra/blob/master/docs/copy-sync.md */
	[@bs.module "fs-extra"] external copySyncExternal : (string, string, copyOpts) => unit = "copySync";

	let copySync = (~overwrite=?, ~errorOnExist=?, ~dereference=?, ~preserveTimestamps=?, ~filter:option(string => bool)=?,
	src: string, dest: string) =>


	//FightCode can only understand your robot
	//if its class is called Robot
	var Robot = function(robot) {

	};

	Robot.prototype.onIdle = function(ev) {
	var robot = ev.robot;
	robot.clone();

	//FightCode can only understand your robot
	//if its class is called Robot
	var Robot = function(robot) {
	var rx = robot.position.x;
	var ry = robot.position.y;
	var aH = robot.arenaHeight;
	var aW = robot.arenaWidth;
	robot.clone()
	};
