Using a proxy for persistence in TypeScript

	class Account {}

	getAccounts(): Account[]

blrobin2 / ReadStreamFactory.ts

Last active December 8, 2017 13:49

A wrapping factory object for node.js createReadStream to promisify the read stream. Handles adding and removing event listeners for GC.

	import { createReadStream, ReadStream } from 'fs'

	class ReadStreamFactory {
	private readStream: ReadStream
	private promiseResolve: (stream: ReadStream) => void
	private promiseReject: (reason: Error) => void

	static createReadStream(filename: string): Promise<ReadStream> {
	const factory = new ReadStreamFactory(filename)
	return factory.promisifyReadStream()

blrobin2 / missingRequired.js

Created September 25, 2017 18:39

A dumb way of checking if required parameter is passed

	function missingRequired() {
	const thisFunc = arguments.callee;
	const caller = thisFunc.caller;
	const passedArgs = caller.arguments;
	const args = caller.toString()
	.replace(/((\/\/.$)\|(\/\[\s\S]?\\/)\|(\s))/mg,'') // remove all spacing
	.split(/function\s*\w+\(?/)[1] // remove 'function name ('
	.split(/\)\s*\{/)[0] // remove everything after ){
	.split(/,/); // break apart into comma separated list of arguments

blrobin2 / singly-linked-list.js

Created July 12, 2017 16:58

A naïve approach at a SinglyLinkedList object in JS

	class SinglyLinkedList {
	constructor(value = []) {
	if (Array.isArray(value)) {
	value.forEach(val => this.addAtEnd(val))
	} else {
	this.value = value
	this.next = null
	}
	}

blrobin2 / proxies.js

Extending Dr. Axel Rauschmayer's RESTful web service example

	// Source http://exploringjs.com/es6/ch_proxies.html#_accessing-a-restful-web-service-method-calls

	const gitHubService = createWebService('http://api.github.com');

	gitHubService.feeds.get().then(data => {
	console.log(data.timeline_url);
	});

	gitHubService.users.blrobin2.get().then(data => {
	console.log(data.avatar_url);

blrobin2 / EventStore.php

Created July 14, 2015 21:34

I like to use Doctrine in Laravel, and I needed an annotated event store class for the table. If you utilize event sourcing, and especially if you use Qandidate Labs Broadway package, this could be useful.

	<?php

	use Doctrine\ORM\Mapping as ORM;

	/**
	* Class EventStore
	*
	* @ORM\Entity
	* @ORM\Table(name="event_store")
	*/

blrobin2 / helpers.php

Created July 4, 2015 02:15

This is my helpers file I've been using in a few Laravel projects. Just throwing it up here because, why not?

	<?php

	/**
	* Checks for an image and moves it to the set folder.
	*
	* @param $image . The image, most likely from the Request object
	* @param $destination . The folder in source where it's going.
	* @return null\|string
	*/
	function moveImage($image, $destination)
