Part one: 7 must-know object-oriented software patterns (and their pitfalls)

Object-oriented (not orientated!) design is a fundamental principle of modern software engineering, a crucial concept that every developer needs to understand and employ effectively. Software design patterns like object-oriented design serve as universal solutions to common problems, across a range of instances and domains. As software engineers advance in their careers, they actually often start using these patterns instinctively, even without knowing it.

Why every developer needs to learn about source maps (right now)

You did it! Sure, it might be four weeks overdue and late on a Friday, but you’ve finally finished deploying a long-awaited update to the web app. However, your celebrations are cut short as your phone vibrates off the table. Picking it up, you’re confronted with a developer’s worst nightmare. You’re getting flooded with messages that the login is no longer working. Was it your deployment? This is bad. Nobody can use the site if they can’t log in.

Introducing Error Groups to the Raygun API

We’re excited to announce an important extension to our API. After rigorous research, testing, and feedback, we’ve launched the Error Groups endpoints. This powerful new addition aims to enhance your monitoring experience and better handle errors across your applications. Our primary aim with the introduction of these endpoints is to offer you a more detailed view into your applications’ error groups, and to offer a way to update their statuses using the API.

Part two: 7 must-know object-oriented software patterns (and their pitfalls)

Dr. Panos Patros, CPEng This is the second and final part in our exploration of must-know OOP patterns, and covers the composite bridge pattern, iterator pattern, and lock design pattern. Find part one here covering extension, singleton, exception shielding and object pool patterns. Object-oriented design is a fundamental part of modern software engineering that all developers need to understand.

New Raygun JS provider v2.27.0 to support performance timing

The popular chromium based browser ecosystem has recently changed how performance metrics can be collected in relation to performance.timing. Before we get into the details, the TLDR is: if you use the Raygun CDN for raygun4js, you’re up to date. If you self-host raygun4js and use Raygun Real User Monitoring, you’ll want to upgrade to version 2.27.0.

A guide to single-page application performance

Many of us have heard single-page applications (SPAs) hailed as the future of web applications. Proponents of SPAs point to increased code reusability and development velocity, and the advantage SPAs can give when it comes to delivering a fast and seamless user experience. Massive sites like Facebook, AirBnB and Trello are all built as SPAs. On the flipside, monitoring SPAs for performance is pretty challenging.

Best practices for tracing and debugging microservices

Tracing and debugging microservices is one of the biggest challenges this popular software development architecture comes with - probably the most difficult one. Due to the distributed architecture, it's not as straightforward as debugging traditional monolithic applications. Instead of using direct debugging methods, you'll need to rely on logging and monitoring tools, coding practices, specific databases, and other indirect solutions to successfully debug microservices.

The key to secure transmission: TLS in the Raygun ecosystem

As our lives increasingly move online and data becomes the lifeblood of business, secure data transmission is imperative. From personal conversations to financial transactions, from healthcare records to sensitive business data, nearly everything we do online requires trust that our data is protected. And if you’ve ever made an HTTPS request, TLS is behind it, providing that trust.

Server performance metrics: 11 to consider for actionable monitoring

With the DevOps movement becoming mainstream, more and more developers are getting involved with the end-to-end delivery of web applications, including deployment, monitoring performance, and maintenance. As an application gains more users in a production environment, it’s increasingly critical that you understand the role of the server.
