Overview This is part two of a two-part series of tutorials about regular expressions in Go. In part one we learned what regular expressions are, how to express them in Go, and the basics of using the Go regexp library to match text against regular expression patterns.  In part two, we will focus on using the regexp library to its full extent, including compiling regular expressions, finding one or more matches in the text, replacing regular expressions, grouping submatches, and dealing with new lines. Using the Regexp Library The regexp library provides full-fledged support for regular expressions as well as the ability to compile your patterns for more efficient execution when using the same pattern to match against multiple texts. You can also find indices of matches, replace matches, and use groups. Let's dive in. Compiling Your Regex There are two methods for compiling regexes: Compile() and MustCompile() . Compile() will return an error if the provided pattern is inva...

In my previous article I covered Stimulus—a modest JavaScript framework created by Basecamp. Today I'll talk about internationalizing a Stimulus application, since the framework does not provide any I18n tools out of the box. Internationalization is an important step, especially when your app is used by people from all around the world, so a basic understanding of how to do it may really come in handy. Of course, it is up to you to decide which internationalization solution to implement, be it jQuery.I18n , Polyglot , or some other. In this tutorial I would like to show you a popular I18n framework called I18next that has lots of cool features and provides many additional third-party plugins to simplify the development process even further. Even with all these features, I18next is not a complex tool, and you don't need to study lots of documentation to get started. In this article, you will learn how to enable I18n support in Stimulus applications with the help of the I18nex...

Overview Regular expressions (AKA regex) are a formal language that defines a sequence of characters with some pattern. In the real world they can be used to solve a lot of problems with semi-structured text. You can extract the important bits and pieces from text with a lot of decorations or unrelated content. Go has a strong regex package in its standard library that lets you slice and dice text with regexes.  In this two-part series, you'll learn what regular expressions are and how to use regular expressions effectively in Go to accomplish many common tasks. If you're not familiar with regular expressions at all, there are lots of great tutorials. Here is a good one . Understanding Regular Expressions Let's start with a quick example. You have some text, and you want to check if it contains an email address. An email address is specified rigorously in RFC 822 . In short, it has a local part followed by an @ symbol followed by a domain. The mail address will be separ...

In this article, we're going to explore the notification system in the Laravel web framework. The notification system in Laravel allows you to send notifications to users over different channels. Today, we'll discuss how you can send notifications over the mail channel. Basics of Notifications During application development, you often need to notify users about different state changes. It could be either sending email notifications when the order status is changed or sending an SMS about their login activity for security purposes. In particular, we're talking about messages that are short and just provide insight into the state changes. Laravel already provides a built-in feature that helps us achieve something similar—notifications. In fact, it makes sending notification messages to users a breeze and a fun experience! The beauty of that approach is that it allows you to choose from different channels notifications will be sent on. Let's quickly go through the diff...

There are lots of JavaScript frameworks out there. Sometimes I even start to think that I'm the only one who has not yet created a framework. Some solutions, like Angular , are big and complex, whereas some, like Backbone (which is more a library than a framework), are quite simple and only provide a handful of tools to speed up the development process. In today's article I would like to present you a brand new framework called Stimulus . It was created by a Basecamp team led by David Heinemeier Hansson, a popular developer who was the father of  Ruby on Rails . Stimulus is a small framework that was never intended to grow into something big. It has its very own philosophy and attitude towards front-end development, which some programmers might like or dislike. Stimulus is young, but version 1 has already been released so it should be safe to use in production. I've played with this framework quite a bit and really liked its simplicity and elegance. Hopefully, yo...

Full-text search is crucial for allowing users to navigate content-rich websites. In this post, I'll show you how to implement full-text search for a Laravel app. In fact, we'll use the Laravel Scout library, which makes implementation of full-text search easy and fun. What exactly is the Laravel Scout? The official documentation sums it up like this: Laravel Scout provides a simple, driver-based solution for adding full-text search to your Eloquent models. Using model observers, Scout will automatically keep your search indexes in sync with your Eloquent records. Basically, Laravel Scout is a library that manages manipulation of the index whenever there's a change in the model data. The place where the data will be indexed depends on the driver that you've configured with the Scout library. As of now, the Scout library supports Algolia, a cloud-based search engine API, and that's what we'll use in this article to demonstrate the full-text search implementat...
