Unit Testing in NestJS for Node Using Suites (Formerly Automock)

For years, Automock was a popular framework for defining mocks and stubs in backend test environments. As technology has evolved, new methods and techniques for streamlining the simulation of dependencies in testing have emerged. That's why Automock has been succeeded by Suites, a more modern and robust library. In this article, we'll explore the transition from Automock to Suites, understand what Suites offers, and see it in action in NestJS through a complete example.

Build Custom ActiveStorage Analyzers for Ruby on Rails

In this series, we will take a close look at the architecture of ActiveStorage for Rails. In this first part, we will examine how ActiveStorage treats uploaded data and how to extend this process. The second part will explore how to augment the presentation of uploaded assets. But first, let's quickly define what ActiveStorage does.

Custom API Logic with Server-Side Scripting

Server-side scripting allows developers to create APIs that respond dynamically to user input, security needs, and business logic. Unlike static APIs, server-side scripts interact with databases and external systems to deliver personalized, secure, and efficient responses. Key highlights: Enhanced API Security: Scripts run on servers, reducing risks like code injection and securing sensitive data. Dynamic Customization: Adjust responses based on user roles, input, or workflows. Improved Efficiency.

Beyond the cloud: Inside Bitrise's data center for faster mobile CI

In this webinar, Arpad Kun, VP of Infrastructure and Engineering at Bitrise, sat down with Solutions Architect Lex Zavala to reveal how our team addressed the pain points of traditional cloud-hosted CI and how Bitrise went all-in on a hybrid model—anchored in custom-built infrastructure. The Bitrise engineering team brought software and hardware together and built a vertically integrated, hybrid macOS/Linux private cloud in strategically located data centers to solve the biggest challenges of managing mobile CI/CD at scale.

How to Filter Events in REST APIs

Filtering events in REST APIs lets you request only the data you need, improving efficiency, reducing server load, and speeding up responses. The process involves using query parameters and operators to define conditions for retrieving specific records, like filtering by date, category, or status. Here's the core idea: Query Parameters: Add key-value pairs to the URL (e.g., ?date=2022-03-01) to filter events by specific fields.

CVE Funding Disruption: How Security Teams Can Prepare

The longstanding Common Vulnerability and Exposure (CVE) database has vitally guided security teams for over 20 years, connecting cybersecurity experts, developers, vendors, and researchers in their shared ability to track unknown vulnerabilities in software. But in April of 2025, the MITRE CVE database program was in jeopardy. U.S. government funding for CVE, managed by MITRE and sponsored by CISA, was set to expire. Only in the 11th hour was funding secured, and the contract extended — for now.

How Database Cloning Eliminates Database Provisioning Bottlenecks for Faster Releases

Dev teams often face delays of days or even weeks waiting for database refreshes. The result? Blocked sprint deadlines and delayed releases. Traditional database provisioning methods often create bottlenecks in DevOps pipelines where speed matters most. But there is a solution to this problem: database cloning. It provides fast, space-efficient copies that speed up development velocity.

WWDC 2025: Apple's AI, Swift on Android & Liquid Glass

At the 2025 instalment of its WWDC event, Apple set out its long-term vision for how we think about platform strategy, AI integration and multi-device architecture. If you’re a CTO, staff engineer, or mobile lead, this wasn’t just a conference to watch, it was one to plan your entire roadmap around. What Apple revealed at this year’s WWDS will affect everything from your frontend stack to how your systems talk to hardware.
