Let’s talk about my favorite topic: Laravel.

In Laravel, I often had the situation that I started building something where a package is already there out in the wild. Since I recognized that also for not so common topics packages are existing but also for niche problems, I check google out first before I start programming things. Best example:

I started building my own tax list for my first Product smartdb.io, where I have Stripe implemented for the billing. While researching for the way of writing the reverse charge on the receipt, I found the package from Marcel Pociot which is solving my problems totally: Vat Calculator

But now my list of Packages which I never wanna lose again:

Livewire

Writing reactive UIs is not so intuitive with vue. Ok, you can get it on your plate fast what you have to do, and packages like Interia.js are adorable, but this is nothing compared to livewire. With vue and laravel, you have to create a REST API first and then fire queries and requests to it. Or use Inertia.js, of course, this is making your life easier. With livewire, you can write everything directly in PHP, no need for big JS things. If you want to create something minimal but reactive like the burger-menu on your page, you can use alpine.js. Alpine.js is minimal and functional like tailwind, just check it out.

Horizon

Horizon is a package for managing your queues. It’s so lovely how easy it is to manage multiple, autoscaling queues with it. You can define what queues should run, how much throughput they can have and also what for timeouts etc. they have. Also, the failed jobs are visible in the UI, that’s so good!

Nova

If you didn’t buy Laravel Nova yet, go for it! It’s such a good admin-tool for all your apps, and you can just pay for it if you go live with your app because the license is not limited at your local machine, only for production apps. I also build whole management apps with nova. For example, our Community “Bitkom”: We made a management System for online orders with it, and just with it and mailgun.

Laravel Gravatar

No need for explanation: Never build an upload for an avatar in your MVP again. Here is the package: thomaswelton/laravel-gravatar

Telescope

Debugging your laravel web-application never was more comfortable than with telescope. It’s so pleasant for development purposes. GitHub

socialite

With Laravel socialite, the Social authentification is so secure and comfortable. You want your users to login with GitHub, Facebook, Google, or others? With socialite, it’s done in under 5 minutes. Get it

Cashier

If you start your own SaaS or Shop with laravel, you’ll have the moment to collect money from your users. With cashier and Stripe, it’s easy. Cashier link

Sushi

Sushi was a sponsor package from Caleb Porzio, which is creating Eloquent Models from an array instead of a database connection. Now it’s free to get here: GitHub. I can describe my use-case of this package at best with “better ENUM”. I use it for long lists of countries, specs, or others that are more or less static, for example, taxes, AWS region mappings to AMIs, and such things.

Laravel Debugbar

You all should know it. I use it for years, and I love it. I’ll not explain it too much, but you can debug your MySQL queries, Gates, views, and all other things you need to debug with it. You see how many Queries are executed, you see which views got rendered and all these goodies. Get it

To be honest, I think this list is not complete. Maybe I’ll add a second list and a third and so on. But for now, these are the packages I don’t want to miss.

Let’s set the stage…

We have a list of products that we need to filter. For example, we have a storefront that sells sporting apparel. Each product has a brand (Nike, Adidas etc.) and a category (t-shirts, shoes etc.). We’ll show brands and categories as a list of checkboxes. The user should be able to click on the desired brand and/or category (one or more), then click filter, which will refresh the page showing the filtered results.

Packages

The only package we’ll be using is Spatie’s Laravel query builder. It extends Laravel’s default Eloquent builder by making filtering through large lists easier. Check it out on Github or on Spatie docs. I’ve started using it recently and it has a very fluent API.

Schemas

These models have typical one-to-one relationships, product-to-brand and product-to-category.

I’ve kept the columns to a bare minimum. Product table looks something like this:

$table->text('id'); $table->text('name'); $table->text('description'); $table->text('category_id'); $table->text('brand_id'); $table->text('thumbnail')->nullable(); $table->text('large_preview')->nullable(); 

Category table:

$table->text('id'); $table->text('name'); 

Brand table:

$table->text('id'); $table->text('name'); 

Layout

To get a feel of what this looks like on the front end, we have a column on the left side which lists brands and categories. Each item has a checkbox. The user can check the desired checkbox items and click the filter button.

Below is the snippet for the left panel blade partial. I’ll skip the styling.

<p>Brands</p> @foreach ($brands as $brand) <label class="m-checkbox"> <input name="brand" type="checkbox" value="" @if (in_array($brand->id, explode(',', request()->input('filter.brand')))) checked @endif >  </label> @endforeach <p>Categories</p> @foreach ($categories as $category) <label> <input name="category" type="checkbox" value="" @if (in_array($category->id, explode(',', request()->input('filter.category')))) checked @endif >  </label> @endforeach <button type="button" id="filter">Filter</button> 

Everything is pretty straight forward. The @if conditional is there so once the form is submitted, we can catch the selected id’s through request() object and use them to tick the checkboxes.

Product list renders something like this, again skipping the styles.

@foreach ($products as $product) <p></p> <p></p> <button>Add to Cart</button> <hr> @endforeach 

Javascript

Laravel query builder can filter models based on URL parameters. We’ll use javascript to refresh the page with selected brands and categories. We’re trying to stay away from submitting forms with arrays as names. I have not really found a good way to submit form arrays without swapping brackets with URL safe characters. The query string doesn’t looking appealing when you swap it out. JS method will keep the URL pretty. This also keeps the request() object variable clean, plus it opens the door to other ideas, like submitting through Ajax or Livewire.

<script> function getIds(checkboxName) { let checkBoxes = document.getElementsByName(checkboxName); let ids = Array.prototype.slice.call(checkBoxes) .filter(ch => ch.checked==true) .map(ch => ch.value); return ids; } function filterResults () { let brandIds = getIds("brand"); let catagoryIds = getIds("catagory"); let href = 'products?'; if(brandIds.length) { href += 'filter[brand]=' + brandIds; } if(catagoryIds.length) { href += '&filter[category]=' + catagoryIds; } document.location.href=href; } document.getElementById("filter").addEventListener("click", filterResults); </script> 

When the filter button is clicked, you can collect all the id’s for brand and category. Internally, the getIds function collects all the checkboxes with brand or category names, then filters through, collecting the values of checked checkboxes.

document.location.href=href refreshes the page with the url containing the brand and categories to filter.

document.getElementById("filter").addEventListener("click", filterResults); adds the click event to the filter button.

Controller

The index controller below, without URL parameters, will show all the products. When url parameters are supplied, products will be filtered. Check out Spatie docs for more options.

public function index() { $categories = Category::all(); $brands = Brand::all(); $products = QueryBuilder::for(Product::class) ->allowedFilters([ AllowedFilter::exact('brand', 'brand_id') AllowedFilter::exact('category', 'category_id'), ]) ->get(); return view('products.index', compact('products', 'brands', 'categories')); } 

I hope this helps in your filtering with Laravel project. If you have a question, drop a comment and I’ll be sure to get back to you.

The popular phrase “there’s always room for improvement” rings true no matter what industry you’re in. Even for venerated manufacturers such as Smith & Wesson, SIG Sauer, and Glock, there are always tiny steps here and there that are taken to improve their product. Today we’ll be taking a look at the various Glock generations and explore what improvements (or setbacks) were made to the popular line of polymer Austrian pistols over the years.

A History of Perfection: TFB’s Definitive Guide to all Glock Generations

Glock Generation 1 – 1982

By 1984 Glock was still operating out of just a single building in Deutsch Wagram, Austria. Gaston Glock and 3 employees were hard at work making consumer goods and by the late 70’s even some military hardware. Specifically, the FM 78 Field Knife and machine-gun belt links were at the forefront of their product catalog by the 80s.

The Glock 17 was the first pistol to come to market after nearly 3 years of development within Glock headquarters. The result of this design process was the semi-automatic polymer-framed Safe Action Glock 17 9mm pistol. The pistol was very bare-bones at this point but proved to be functional and reliable and these qualities gave it much favor with various military and police departments across the globe.

The design of the Glock 17 Gen 1 was simple. There was no accessory rail, the magazine release was minuscule and the grip texturing wrapped fully around the entire pistols grip. The grip pattern used on the Gen 1 pistol frames used a “pebble finish” and had no finger grooves.

Early Glock Gen1 pistols made use of a much thinner bore wall than later generations with the early barrels being referred to as “pencil barrels.” These pistols were produced between 1982 and 1986 and featured serial number prefixes “AF” through “AM”.

A History of Perfection: TFB’s Definitive Guide to all Glock Generations

The last notable feature about the Gen 1 Glock pistols was the pistol cases. Early Glock pistols were shipped in the iconic “Tupperware” boxes but Gen 1 Glocks produced and sold in Austria shipped with the case preformed for ammunition storage with these compartments later being removed for importation into the United States. The Generation 1 Glock pistols were produced until 1988 when the Gen 2 Glocks started to make their first appearance.

Glock Generation 2 – 1988

Up until 1988 Glock produced only the Glock 17 model. With the 2nd generation of pistols making their debut in 1988, Glock also released the new Glock 19 – a pistol that would go on to be arguably the most iconic product of the brand. In fact, Hop over on TFBTV argues that the Glock 19 Gen 2 is the greatest generation of Glock to have ever existed.

Gen 2 Glocks saw only minor improvements, some of which were only prompted by pressure from the ATF. For example, Glock had to include a steel serial number plate in order to comply with the BATFE’s regulations (Subpart C—FIREARMS TITLE 27). Other improvements were made to the magazine floorplate and magazine follower spring for improved performance. Glock Gen 2 also holds a special place in my heart as being the pistol heavily featured in the Half-Life series of first-person shooter games.

By 1991 Glock had also made revisions to the grip texturing by adding a checkering pattern to the front and rear instead of just on the sides as they had first been released in 1988. These grip modifications gave the user more purchase on the gun in all conditions. In addition to modifications to the grip design, Glock also introduced several calibers including .40 S&W, 10mm Auto, .380 ACP, and .45 ACP.

In 1995 Glock also introduced the Glock 26 and Glock 27 – the first subcompact pistols made by Glock. These could be considered the first guns that targeted the consumer market rather than the police and military markets.

Glock Generation 3 – 1998

Glock Gen 3 pistols remain to this day some of the most popular handguns on the market. They have been in production for 20 years and are still being produced today and are available for sale. Gen 3 saw the addition of two new calibers (.45 GAP and .357 SIG) and a new feature – an accessory rail. The Universal Glock Rail allowed wielders of the pistols to mount lights and lasers to the gun for added utility.

A History of Perfection: TFB’s Definitive Guide to all Glock Generations

Other improvements were the addition of a thumb shelf on both sides of the pistol to accommodate both left and right-handed shooters. By far the most contentious addition to the Gen 3 Glocks were the finger grooves. Many people, myself included, disliked the finger groves. For me, they gave the otherwise smooth lined pistol an odd feeling and awkwardly spaced out your fingers if they didn’t fit exactly inside the groves. However, not everyone disliked them and I supposed that is why the pistols are still being made to this day – someone is buying them.

The raised extractor indicating the chamber has a round in it.

Gen 3 also added a life-extending cross pin to the rear of the trigger pin which reduced the stress encountered by the locking block when firing the pistol – this improvement leads to longer service life for the pistol. The last major functional improvement to the Gen 3 Glocks was the addition of an extractor which also served as a loaded chamber indicator. When the pistol had a round in the chamber, the extractor would stick up slightly from the frame giving you a visual indicator that the pistol was hot.

Before the start of Glock Gen 4 the Glock 22, 21, 31, 32, and 19 were all being offered in Glock’s new RTF2 (Rough Textured Finish) which had fish-scale style rear slide serrations and a new stippling pattern. These pistols were only offered for a limited time and are no longer being produced.

Glock Generation 4 – 2010

Gen 4 Glocks saw the first dimensional differences to the pistol which to date had been largely identical across generations. The addition of user-serviceable backstraps allowed the user to change both the beavertail and grip of the frame by swapping out Glock Modular Backstraps. The new frames’ base grips were also slightly smaller than previous generations

A History of Perfection: TFB’s Definitive Guide to all Glock Generations

A welcome improvement to Generation 4 was the larger magazine catch/release which was nearly tripled in size and was now reversible for both left and right-handed shooters. There was a minor drawback when it was first introduced as the current generation magazines had issues when the magazine catch was moved to the right side (for left-handed shooting). This problem was later corrected with the introduction of a new generation of magazines designed to circumvent this problem.

A History of Perfection: TFB’s Definitive Guide to all Glock Generations – A Glock Slimline G42 Pistol

The Generation 4 Glocks featured a new dual recoil spring which reduced the recoil felt when shooting and also had the benefit of reducing wear and tear on the gun. Alongside these improvements, two new single-stack “Slimline” pistols were introduced as part of generation 4 in 2014 and 2015. The Glock 42 .380 ACP pistol and the much favored Glock 43 9mm pistol were introduced as subcompact single stack pistols.

Glock Generation 5 – 2017

The newest numbered generation of Glocks made its debut at SHOT Show 2017 and to date has only released a handful of pistols. The current lineup includes only the 17, 19, 26, 34 MOS, 17 MOS, and 19 MOS pistols. The MOS pistols share a unique optics mounting plate for the addition of a micro red dot – something that spilled its way over into the United States Military Modular Handgun System competition.

A History of Perfection: TFB’s Definitive Guide to all Glock Generations

Both the Glock 47 and 45 have since been added to the list of offerings with both being used by United States Customs and Border Patrol agents as their new duty weapon. However, more than just combinations of the already existing slide and frame sized were being added. Gen 5 also saw the addition of a flared magazine well, trigger guard relief cuts for a higher grip as well the first major changes to the internal components.

A History of Perfection: TFB’s Definitive Guide to all Glock Generations

The internal workings of Glock pistols had more or less remained unchanged since the Gen 1 Glock was introduced, however, the Gen 5 saw the removal of the cross pin that would normally be above the trigger guard. Glock also replaced the standard barrel with a Glock Marksman barrel for all Gen 5 Glocks and lastly, the outer coating is a newer nDLC coating. I’m not personally a fan of this newer coating as I much prefer the Tennifer ferritic nitrocarburizing that has been around and lasted throughout the decades on previous generations of Glocks.

Glock Sliver Slimline Era – 2019

The Slimline series of Glocks were released in early 2019 and made waves when they were revealed to the public. The Glock 48 and 43X were both single-stack 10 round capacity pistols using the Glock Slim 01 magazines. Not quite a Glock 19 but also not a Glock 43 and having features from the last three generations of Glocks makes these pistols almost a generation of their own.

A History of Perfection: TFB’s Definitive Guide to all Glock Generations

One thing that sets the 43X and 48 (as well as the 43 and 42) is the unique firing pin and striker. All four of the pistols share the same striker and firing pin and these components are not compatible with any other generation of Glock pistol. Furthermore, the Slimline pistols nixed the finger groves from the Gen 3’s as well as the modular backstraps from Gen 4 and Gen 5 but at the same time add their own flair with an increase single-stack magazine capacity, a silver PVD finish and forward slide serrations.

A History of Perfection: TFB’s Definitive Guide to all Glock Generations

Regardless of where these Silver Slimline pistols fit they are no longer being produced as they have been replaced by the more traditional all-black models which carry the same features but lack the non-reflective PVD coating. By far these Slimline Glocks have to be my favorite generation of pistols.

More to Come?

Glock continues to make improvements to their long line of pistols and is even branching out into new territory with the recently released Glock 44 22LR pistol. I would expect Generation 5 Glocks to continue for quite a while until we start seeing any signs of Gen 6 Glocks and by then who knows what we will see happen to the popular polymer pistol brand. What is your favorite generation and model of Glock and why? Let us know down in the comments!
