By default the script will delete files older than a year. You can change that in the TIMESTAMP variable.

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

	# www.fduran.com
	# Create Java KeyStore from SSL certificate for domain example.com

	# Change format from cert.crt PEM (----BEGIN CERTIFICATE----- ... -----END CERTIFICATE-----) to DER
	openssl x509 -in cert.crt -inform PEM -out cert.der -outform DER

	# create KeyStore cert.jks for your domain ("alias" in keytool, "common name" or CN in openssl req)
	keytool -import -trustcacerts -alias example.com -file cert.der -keystore cert.jks

-var https = require('https');
-// CONFIGURATION #######################################################################################################
-var token          = '';
-var delay          = 300; // delay between delete operations in millisecond
-// GLOBALS #############################################################################################################
-var baseApiUrl    = 'https://slack.com/api/';

	"use strict";

	// Load plugins
	const autoprefixer = require("autoprefixer");
	const browsersync = require("browser-sync").create();
	const cp = require("child_process");
	const cssnano = require("cssnano");
	const del = require("del");
	const eslint = require("gulp-eslint");
	const gulp = require("gulp");

	# send logs for all traffic (including non-html) to google analytics
	#
	# in server block:
	# set $google_analytics_id "UA-THECORRECT-ID";
	# include /srv/nginx/google_analytics;
	#
	# in location blocks:
	# post_action @ga;
	#
	# notes: post_action has been referred to by nginx devs as a "dirty hack" and this approach may stop working one day.
