Laravel Companion

A Guide to Helpers, Collections And More

About the Book

The Laravel framework contains many useful helper functions, features and utility classes (such as Collections) - not all of these are well known. This book exposes these helper utilities to encourage accelerated application development using the Laravel framework (version 5.3). Through the Laravel Companion you will learn about collections, facades, application helper functions, request and URL helper functions and much, much more.

If you've ever thought there "has to be an easier way" - there probably is in the form of a helper utility.

About the Author

Johnathon Koster
Johnathon Koster

Hello, internet!

My name is John, and I have over fifteen years of professional software development. I've worked on a wide range of projects over the years, from simple websites and critical government reporting applications all the way to high-performance telematics solutions.

During my downtime, I enjoy working on open-source projects, writing posts on my blog, and contributing to the Laravel and Statamic ecosystems.

Some of the recent open-source projects I've worked on include:

  • blade-parser-typescript - a Laravel Blade parser, formatter, reflection library, and linter, written in TypeScript
  • Antlers Toolbox - a Visual Studio Code extension providing syntax highlighting, code auto-complete, intelligent refactoring, and project-aware assistance for Statamic developers
  • Antlers Runtime - an advanced PHP templating engine for the Statamic CMS platform
  • Proteus - a Laravel package that makes it simple to read, write, and modify Laravel configuration files from your application code
  • Primitives - a PHP library that safely parses input strings into native PHP types (string, bool, arrays, etc.) and can optionally be configured with a sandbox for method evaluation
