Using Namespaces and Autoloading in WordPress Plugins, Part 4
Jan 19, 2017 @ 10:24:36

The TutsPlus.com site has posted the fourth part of their series covering the use of namespacing and autoloading in WordPress plugins. In this latest tutorial they take everything they've shared (and made) previously and put it all together into a cohesive whole plugin.

At this point, we've laid the foundation for our plugin, written the plugin, and defined and explored namespaces and autoloaders. All that's left is to apply what we've learned.

So in this tutorial, we're going to put all of the pieces together. Specifically, we're going to revisit the source code of our plugin, namespace all relevant classes, and write an autoloader so that we can remove all of our include statements.

He starts off talking about namespacing and how it relates to directory structure and the code you'll need for each of the plugin files for put them in the correct namespace. With just these in place, however, errors are thrown. This requires the setup of a custom autoloader and PHP's own spl_autoload_register handling. He includes the code for the autoloader, taking in the class name and splitting it up to locate the correct directory, making it easier to replace the loading of all plugin scripts.

Mattias Noback:
Containerizing a static website with Docker, part III
Jan 09, 2017 @ 11:48:46

Matthias Noback has posted the third part of his "containerizing a static website with Docker" service, continuing on from his previous two posts to look at deploying the environment he's created.

In the previous posts we looked at creating a build container, and after that we created a blog container, serving our generated static website.

It's quite surprising to me how simple the current setup is — admittedly, it's a simple application too. It takes about 50 lines of configuration to get everything up and running.

The idea of the blog container, which has nginx as its main process, is to deploy it to a production server whenever we feel like it, in just "one click". There should be no need to configure a server to host our website, and it should not be necessary to build the application on the server too. This is in fact the promise, and the true power of Docker.

He then gets into the two remaining steps in the process resulting in the deployment of the simple application: pushing to Docker Hub and deploying out to a DigitalOcean server. He includes all of the commands and configuration you'll need to get the process set up and work with the remote machine.

Containerizing a static website with Docker (Part 1 & 2)
Jan 06, 2017 @ 09:07:39

Matthias Noback has started a series to his site showing you how to use Docker along with a static site, like one generated with Sculpin to create a complete environment. So far he's posted part one and part two.

Recently a former colleague of mine, Lucas van Lierop, showed me his new website, which he created using Spress. Lucas took two bold moves: he started freelancing, and he open-sourced his website code. This to me was very inspiring. I've been getting up to speed with Docker recently and am planning to do a lot more with it over the coming months, and being able to take a look at the source code of up-to-date projects that use Docker is certainly invaluable.

Taking lots of inspiration from Lucas's codebase, and after several hours of fiddling with configuration files, I can now guide you through the steps it took to containerize my blog (which is the site you're visiting now) and deploy a single container to a production server.

In part one he talks about how his blog is currently set up - based on a "large set of Markdown files" - and using Sculpin to generate the resulting site. He walks through the configuration of the Sculpin installation and how to configure and build the initial container, the "build" container.

In part two he continues the process but creates a "blog" container this time. This container runs the web server itself (nginx) configured as required by the Sculpin formatting.

Programming With Yii2: Using the Debugger
Jan 03, 2017 @ 11:52:29

The TutsPlus.com site continues their "Programming with Yii2" series of tutorials with the latest edition in the series, a look at using the Yii2 debugger to help track down issues in your code.

In today's tutorial, I'll show you how to install the Yii2 Debugger, and we'll explore its capabilities in detail. It's a powerful programming assistant which is often underutilized.

As you code and test your application, the debugger can show you your application path, queries and query variables, performance characteristics, server and framework settings, and much more.

The article starts off by showing you how to install the "yiisoft/yii2-debug" library (via Composer) and enable it in the "debug" section of your configuration. With it correctly installed you'll then be able to access it at the bottom of your pages. The debug console provides plenty of helpful information related to:

  • the route matched
  • a log of actions and events
  • load time
  • memory used
  • database queries performed

...among others. The tutorial walks you through these and other pieces of information the tool provides with screenshots of example output for each.

Building Your Startup: Ajax for Meeting Times and Places
Jan 02, 2017 @ 13:10:42

The TutsPlus.com site has posted the next in their "Building Your Startup" series of tutorials covering the use of Yii2 to create a calendaring application. In this new part of the series they continue migrating some functionality over to use an Ajax-powered system, reducing the need for page reloads.

Last week, I delved deeper into Ajax to transform the meeting scheduling experience into a fully ajaxified model and eliminated the need for page refreshes. I got about halfway, focusing mostly on the straightforward elements.

In today's tutorial, I'll guide you through the more complex content panels that required a lot more troubleshooting, research, debugging, brainstorming, and recoding. [...] I'm also going to show you how I used Google's Chrome browser developer console to help me identify the broken areas—which can be especially difficult when working with Ajax between PHP and JavaScript. It's like light at the end of the tunnel of darkness.

The tutorial then walks through the updates needed to move over various pieces of functionality to the Ajax-driven model:

  • adding meeting participants
  • adding dates and times
  • adding meeting places

There's also a few screenshots included of the Chrome developer console and what some of the example request/responses look like, helping you debug your own development work.

Programming With Yii2: Helpers
Dec 27, 2016 @ 11:13:44

The TutsPlus.com site has continued their "Programming with Yii2" tutorial series with a new post introducing you to helper functions that come bundled with the framework. It also shows you how to create your own custom helper function, making it easier to perform common functions custom to your application.

In the Programming With Yii2 series, I'm guiding readers in use of the Yii2 Framework for PHP. In this tutorial, I'll provide a brief overview of helpers. In Yii, helpers are modules which group commonly useful libraries for string, file, image, URL and HTML management amongst other things, and they are easy to extend.

I'll also share an example of creating a helper within Meeting Planner, the focus of our Envato Tuts+ startup series.

The tutorial then introduces you to (and links you to) the common helpers the framework comes bundled with including the ArrayHelper, FileHelper and Markdown helpers. The tutorial then covers two in a bit more detail, the ArrayHelper and HtmlPurifier helper, including some code examples for each. Finally it shows the creation of a custom helper with several custom functions and their use in a template.

Master Zend Framework:
How To Use Forked Repositories In Composer
Dec 21, 2016 @ 12:40:09

The Master Zend Framework site has continued their series covering Composer and some more advanced concepts than just the usual introduction. In this new tutorial Matthew Setter shows you how to work with forked repositories.

Have you ever submitted a patch to a repository which your application relies on, but, because that patch is vital to the uptime of your application, you can’t wait for it to be reviewed and merged into the next release?

In times like these, it’s fair to want them to move faster than they normally would, so that you don’t have to wait for the normal review, merge, and release cycles. [...] But, you may urgently need the patch to be applied and released. So, what do you do? In times like these, you can use Composer’s ability to use custom repositories, specifically a fork which you create and patch.

If this sounds appealing to you — because perhaps you’re in this very situation right now — let’s now step through the process of modifying your composer.json configuration so that you can use one.

He walks through the Composer configuration you'll need to update to work with the forked repository as you'd expect. He also covers changes that would need to be made for working with private repositories and using local files instead of remote.

Matt Stauffer:
Update to queue workers in Laravel 5.3
Dec 21, 2016 @ 09:47:38

Continuing his series about new functionality in Laravel v5.3 Matt Stauffer has posted this quick article covering updates to the queue worker functionality.

Queues are one of those tools in Laravel that everyone knows is there, but very few people understand deeply. It's understandable--Laravel is often the first place folks have run into queues, and to be honest, they're not simple.

Thankfully, very little has changed on a user-facing front with regard to how queues work in Laravel 5.3.

One of the main updates is that the "listen" command is now "work" and the action then runs as a daemon by default instead of requiring the command to be long-running. He talks about the difference in this shift and how something like Supervisor can now be used to manage the daemon (including some documentation specific to Laravel). He finishes the post looking at what has changed "under the hood" and the benefits the changes bring.

Building Your Startup: Security Basics
Dec 20, 2016 @ 11:55:58

The TutsPlus.com site has continued their "Building Your Startup" tutorial series with this latest article covering the "security basics" you'll need to adequately protect your application. This tutorial touches on both the server-level and code-level security aspects.

In today's episode, we'll dive into the basics of web server security. I'll cover securing the Linux VPS running Meeting Planner and some basic Yii security. In the next episode, I'll dive more into programmatic Yii application security.

The article starts off with the server side of things, introducing hosting options, keeping the server updated, configuring SSH for logins, setting up a firewall and SSL. With that solid base in place, it then starts on the code side covering the built-in functionality used to secure the backend and frontend functionality.

Scaling Laravel Using AWS Elastic Beanstalk Part 2: Setting up VPC, RDS and Ela
Dec 15, 2016 @ 10:56:06

On the DeliciousBrains.com site they've posted the second part of a series covering the scaling of a Laravel-based application using Elastic Beanstalk (part one is here).

In my last article we decoupled Laravel and got it ready for deployment to the Elastic Beanstalk architecture. However, before we race ahead to actually deploying our code to Elastic Beanstalk we need to do some preparation first. Specifically we need to set up some other AWS services that will be used by our Laravel app. These include: Virtual Private Cloud (VPC) to keep our infrastructure secure, Relational Database Service (RDS) for our MySQL database and ElastiCache for our Redis cache

With these “supporting” services up and running we can finally move on to deploying our Laravel app to Elastic Beanstalk.

They start off by walking you through the creation of the VPC on the AWS services using both public and private subnets. With that in place they move on to the RDS setup, configuring it to host their MySQL database and making a test connection. Finally they set up the ElastiCache instance for the Redis handling finishing out their "supporting services" setup in AWS.
