Laravel 5.x Cookbook

Chapter 2. Using Composer Packages

In this chapter, we will cover the following topics:

  • Working with the composer install command and avoiding the Composer update
  • Downloading and installing Guzzle using Composer
  • Making a provider
  • Using the Facade pattern
  • Using private packages

Introduction

We will cover some of the day-to-day workflows of setting up Laravel to use composer and many of the packages that exist out there for us to easily use in our PHP applications.

Working with Composer install command and avoiding Composer update

Composer is an amazing tool in PHP which allows us to pull in libraries from https://packagist.org/ and even our own private repositories. We will cover how to install a library and note some steps to save time.

Getting ready

We covered installing Composer on your Mac in Chapter 1, Setting Up and Installing Laravel, though you can use it inside Homestead if you need to.

How to do it...

Perform the following steps to install Guzzle using Composer:

  1. In this example, we will use Composer to install Guzzle (a powerful PHP HTTP client). Make sure you are in your App directory, and in this example, I will be on my local computer and not in Homestead just to make the file processing go faster:
    >composer require "guzzlehttp/guzzle":"^6.1"
    

    This will take a minute or less to run.

  2. And that is it!

How it works...

First, let me say this is a good example of a short tip, which is better than a long one. Maybe other instructions...

Making a provider

In the previous section, we used composer to pull in Guzzle, so we're ready to use it in our project. However, we'd rather not have to instantiate the Guzzle client manually every time we invoke it—hardcoding URLs and authentication and settings with each use. A service provider can help to centralize some of this configuration, and later, we will use service providers to help swap in a mock implementation for testing purposes.

Providers can also help us to avoid writing code that directly calls to a service, which is often a very helpful practice. For example, we may make BillingProvider that can use either Swipe or BrightTree as a billing service. BillingProvider allows us to easily switch between different implementations of the billing service.

Getting ready

Follow the steps in the Working with Composer install command and avoiding composer update section to pull in Guzzle, and start up your terminal.

How to do it...

The following steps will help you in...

Using the Facade pattern

Using the preceding work, let's take it one step further in how easy it is to use this Client in our code.

Getting ready

Install Guzzle and set up the provider just as we did previously, and you are ready for this next recipe.

How to do it...

  1. Make a folder called Facades in your app folder.
  2. Then add a file called APIClient.php and make it look like this:
    How to do it...
  3. Then scroll way down to the Façade section of this file, where we can register the Facade in our config/app.php file like this:
    How to do it...
  4. Now, let's see it working in a test by adding the method called seeing_our_facade_work to our test:
    How to do it...
  5. Now run the test:
    How to do it...

How it works...

So, the amount of work is all it takes to make your Provider just as easy to use as View, File, Storage, and all the other Facades that come from Laravel that make it easy and enjoyable to use.

Also, we can change the test to show it being just as easily swapped out. We will cover this in the testing chapter.

Using private packages

Sometimes, you need to use a private repository on GitHub or another location. I will cover here how to set this up in your composer.

Getting ready

We need a private repo, so if you have it and its composer.json is set up properly, you will be set from there.

How to do it...

  1. First, go to GitHub and navigate to SettingsPersonal access tokens:
    How to do it...
  2. At the command line, type this:
    >composer config –g github-oauth.github.com THE_TOKEN_FROM_ABOVE.

  3. Then, edit composer.json so that there are two new sections:
    How to do it...
  4. Then, let's tell the composer to install this:
    >rm –rf composer.lock vendor
    >composer install
    

How it works...

Alright, let's talk about these steps. The first one is to make sure we are setting up our Homestead or Mac for easy access to the private repository. This is really key as well if you are doing 2FA on your GitHub account (which you should be doing). Step 2 wraps this up by adding it to your ~/.composer configuration.

I'd be able to give it more stars if I could read the code examples. Unfortunately they have been take from screenshots of a code editor with a dark profile, so some code is indistinguishable from the background.The content may be great, but in terms of print and presentation, is not as good as the O'Reilly 'Cookbook' series.

I guess it was my fault really. I was looking for a good book for beginners but made a wrong purchase. The author is a programmer and not a teacher . Most of the content made assumptions that you were an advanced user of Laravel. The only concession wa the first chapter where you were introduced to the basic setup., and even for half of that chapter the reader is sent away somewhere or the other to get how-to information. I could have saved my money and downloaded free tutorials instead...which I eventually did . From the second chapter to the end the author was completely immersed in displaying his brilliance at programming and on his brilliant project he is working on in this Cookbook. It is a distressing book . I'd possibly eventually use it as a door stop. It is that heavy !
