Node.js has moved beyond being a developer favorite, it’s a cornerstone of the digital economy. Today, it powers tens of millions of applications globally, and it underpins mission-critical systems at companies like Netflix, PayPal, Uber, and NASA. The foundation of this success is its asynchronous, event-driven architecture, designed to handle thousands of concurrent connections efficiently. From e-commerce platforms to video calls to real-time analytics, Node.js enables responsiveness at scale.

Managing event schema evolution is a key challenge for API gateways, especially in systems relying on real-time data and microservices. Schema evolution ensures that updates to data structures remain compatible with existing integrations, preventing issues like service outages or data corruption. The article explores methods to handle schema changes effectively and highlights DreamFactory’s automated solution.

As consumer expectations rise, loyalty is becoming a top priority. In fact 67% of brands plan to significantly increase investment in strengthening consumer loyalty over the next year, according to a recent report by Apadmi, Europe’s leading digital product consultancy and longstanding Bitrise customer.

Retrieval-Augmented Generation (RAG) lets LLMs deliver current, context-rich answers by fetching live data—customer records, knowledge articles, metrics—from SQL Server, MySQL, and PostgreSQL. Reports suggest RAG can boost answer accuracy dramatically (in some cases up to 90%), making it compelling for BI, support, and operations. The challenge: enabling on-the-fly retrieval without opening security, compliance, or scalability risks. Executive takeaway: Don’t let LLMs write SQL.

If you work with Elixir, chances are you've used structs plenty of times and are likely aware of Ecto schema. However, you may not have explored structs in depth or used Ecto schemas beyond the database context. In this post, we'll explore the ins and outs of structs and Ecto schemas.
