As a Ruby developer, you have probably used the map method to transform arrays and other collections of data. But have you ever needed to transform an array and flatten the result in one go? This is where the flat_map method comes in.

In Ruby 2.4, a new method called transform_values was introduced to help transform hash values using a block. This method can be particularly useful when you need to modify the values in a hash without changing the keys.

Horizontal scaling is the process of adding more servers to handle increased traffic and user activity in your Ruby on Rails application. With horizontal scaling, you can handle more requests by distributing the load across multiple servers, rather than relying on a single server to handle all the traffic. In this article, we will discuss how to implement horizontal scaling in Ruby on Rails, with a code example.

In Rails 6.1, a new method called compact_blank was introduced to help filter out nil and blank elements from an array. This method can be particularly useful when working with form parameters, where some fields may be left blank or undefined.

Load balancing is an important technique for scaling Ruby on Rails applications to handle high traffic loads. In this article, we will discuss load balancing and some techniques for implementing it in Ruby on Rails, along with code examples.

Database optimization is an important aspect of building high-performance Ruby on Rails applications. In this article, we will discuss some techniques for optimizing database performance in Ruby on Rails, along with code examples.

Caching is a technique that can improve the performance of your Ruby on Rails application by storing frequently accessed data in memory or on disk. In this article, we will explore how to use caching in Ruby on Rails, and we will provide some code examples to illustrate the different types of caching available.

Building a Rails controller is simple and well documented. Follow the ‘Rails way’ and your life is easy. However, webhook endpoints require a different approach. In this post you’ll learn how to build maintainable and secure webhook endpoints.

Ruby on Rails is a popular web application framework that is widely used to develop complex web applications quickly and efficiently. One of the essential parts of developing a robust Ruby on Rails application is testing. Testing is crucial to ensure the application is working correctly and doesn’t have any bugs or errors that could lead to problems for users. In this article, we’ll discuss the best practices for testing Ruby on Rails applications, including unit testing, integration testing, and more.

Debugging Ruby on Rails applications can be a time-consuming and challenging task. In this article, we’ll explore some common issues that developers face and provide tips and tricks for solving them with code examples.

This tutorial explains how to send Slack messages from a Rails application.

This post explains how to iterate over the contents of an AWS S3 bucket and generate download links for each object. This example uses aws-sdk version 2. At the time of writing, version 3 is the latest but there’s still a lot of legacy apps that use v2.

Recently, we worked on deploying a legacy Rails app to Heroku. The minimum Ruby version that Heroku supports is 2.7.6. Apps running older versions must be upgraded before they can be deployed. Thankfully, this problem can be solved by deploying the app as a container. This post explains how to containerize an application and deploy it to Heroku.

In part 1 we built an admin panel and used Turbo Streams to make revenue dynamic. In this post we’ll continue building out the admin panel. We’ll implement tabs, using Turbo Frames, then finish up by making ‘real time orders’ dynamic.

In this series we are building an admin panel, using Hotwire. The admin panel will have multiple tabs and plenty of interactivity. Let’s get started.

Recently, we encountered a bug with some Stimulus code. We were trying to stream updates for a small partial and found that data only refreshed on the first update.

A dedicated software development team is a collaborating model in which a client engages an outsourced team of project managers, software developers, QA testers, and other specialists offered by the software development vendor.

In part 1 we built a Stimulus controller that tests a regex, however, there is a problem with that solution. Ruby and JavaScript regex implementations are slightly different. In our case, we want users to verify their regex using Ruby’s regex implementation. To do that, we need to evaluate the regex on the server side.

Leaders in various industries are embracing digital tools to improve their firms. It could be to begin digital changes, support new remote workforce models, improve customer relations, or automate processes. Fortunately, software is now more widely available than ever. The power of choice, on the other hand, might be overwhelming. Furthermore, your technological decisions can mean the difference between falling behind or staying ahead in your sector.

With the average time between filing a claim and receiving payment approaching 7 weeks or more, the demand for cost-effective and efficient medical billing solutions is unsurprising.

Customer relationship management is critical in any firm. This is what enables entrepreneurs to facilitate interactions that ultimately convert leads into paying consumers. The processes involved in CRM efforts, on the other hand, can be rather tedious.

We’re building an app that requires users to input a regex. We’d like to build a feature that gives users the ability to test their regex, before saving. The feature will work a lot like Rubular. Users will be able to test their regex against various strings.

During a recent Rails 5 -> 6 upgrade we encountered an ES6 bug. Here’s the error message:

Rails 5 uses 't' and 'f' to represent booleans, in SQLite databases, because there is no native boolean support. In Rails 6, the behaviour changed to represent booleans as 1 or 0.

There are 4.4 million apps available on both the Appstore and Google Play, aimed at the world’s 14 billion mobile phones. If you want to create a mobile app, one of the most crucial decisions you must make is whether to use native or cross-platform mobile development.
