andrey-kazakov / DeferredComponent.jsx

Last active August 29, 2015 14:27

It's a solution to asynchronously load React components used internally in our project. It has a quite simple logic, so just read the script and use it as you want. It depends on jQuery.ajax and jQuery.Deferred, but you can easily avoid it. Loaded script should just do `window.deferredComponents['YourReactComponent'].resolve(YourReactComponent)`

	var DeferredComponent;

	DeferredComponent = React.createClass({
	propTypes: {
	componentName: React.PropTypes.string.isRequired
	},

	getInitialState: function() {
	return {
	resolvedComponent: null,

andrey-kazakov / FocusMonitorMixin.js

Created May 17, 2015 13:19

React focus monitor mixin (click or focus outside of monitored node calls a handler)

	module.exports = {
	componentWillUnmount: function() {
	this.endFocusMonitor();
	},

	startFocusMonitor: function() {
	document.addEventListener('focusin', this.checkFocusTarget);
	document.addEventListener('click', this.checkFocusTarget);
	},

andrey-kazakov / Gemfile

Created January 29, 2013 20:04

My solution for platform-independent testing with guard gem on Mac/Linux. This code installs both rb-fsevent/rb-inotify gems on all platforms (and this way it won't cause platform conflicts with Gemfile.lock), but really requires only needed one.

	group :test do
	gem 'guard'
	###
	gem 'rb-fsevent', '~> 0.9.1', require: (RUBY_PLATFORM.downcase.include?("darwin") && 'rb-fsevent')
	gem 'rb-inotify', '~> 0.8.8', require: (RUBY_PLATFORM.downcase.include?("linux") && 'rb-inotify')
	end

andrey-kazakov / content_repeat.js.coffee

Created January 23, 2013 23:26

This AngularJS directive, when added to element, repeats it's content as many times as length of given array (almost like ng-repeat). The main difference is that DOM, once built, don't being changed on each $digest(). If you want to force the changing of repeated content, you should emit an event 'invalidateView' with (optionally) name of the sc…

	angular
	.module('ContentRepeat', [])
	.directive 'contentrepeat', ($compile) ->
	priority: 1000
	terminal: true
	compile: (element, attr, linker) ->
	template = $compile(element.html())
	element.empty()

	(scope, self, attr) ->

andrey-kazakov / robokassa_merchant.rb

Created May 2, 2012 20:08

Robokassa Merchant rails rack middleware

	require 'digest/md5'
	require 'uri'

	# this code works fine in some of my projects, but I'm just lazy to document it well...
	# so, feel free to use it after full review of logic (is it matching your purposes?)
	# at your own risk, of course! :)

	# requires socksify gem
	require "socksify"
	require 'socksify/http'

	# use w/ OAuth2 like OAuth2::Client.new(id, secret, connection_opts: { proxy: 'socks://127.0.0.1:9050' })
	class Faraday::Adapter::NetHttp
	def net_http_class(env)
	if proxy = env[:request][:proxy]
