Node.js Resiliency Concepts: Recovery and Self-Healing

In an ideal world where we reached 100% test coverage, our error handling was flawless, and all our failures were handled gracefully — in a world where all our systems reached perfection, we wouldn’t be having this discussion. Yet, here we are. Earth, 2020. By the time you read this sentence, somebody’s server failed in production. A moment of silence for the processes we lost.

Going from Consulting to SaaS

For many freelancers and small business owners, moving from consulting or freelance development work to operating a SaaS product is the Holy Grail. That makes sense: running a SaaS scales better and makes for a stable income. While there’s no guaranteed path to success, here’s what we learned taking AppSignal from a “20% time side-project” to a business serving thousands of developers around the globe. This article isn’t a blueprint.

Identifying and Resolving a Kafka Issue With AppSignal

Last week, we had an issue with one of our Kafka brokers. Don’t worry, it didn’t impact any customers. When monitoring things closely, you can often solve things before they impact a customer ;-). In today’s post, I’ll show you how we use AppSignal to dogfood our own issues. I’ll go through how we monitor the non-Ruby part of our stack and how we used AppSignal to detect and resolve the issue.

Security Best Practices for Node.js

Because a lot of systems are connected to the web these days (or, at least, communicate/integrate with it at some level), companies are giving more and more attention to web security. Web security usually comes to public attention when certain events reach the news, for example, security leakages, hacker activities, and/or data-stealing over big companies, some of them really large (like Google, LinkedIn, etc.).

AppSignal Ruby Gem 2.11: Active Job and Friends

We just released Ruby Gem 2.11. We are always making things easier to use for you, so more things work out of the box and more instrumentation and dashboarding is built without you doing any heavy lifting. This release has a big overhaul of Active Job support. The cherry on the stroopwafel cake is the automatically generated dashboard with status per queue, queue throughput and queue times. 2.11 also polishes a lot of other integrations. Let’s dive in.

AppSignal Now Supports Redis for Node.js Out of the Box

Starting today with version 0.6.0 of the Node.js integration, instrumenting a Node.js app that uses Redis is much easier. In fact, we instrument it for you - meaning that if you use Redis in your own app, there’s no extra work for you, everything Just Works™ out of the box! 🎉

The State of Elixir HTTP Clients

In today’s post, we’ll look at two Elixir HTTP client libraries: Mint and Finch. Finch is built on top of Mint. We’ll see the benefits offered by this abstraction layer. We’ll also talk about some of the existing HTTP client libraries in the ecosystem and discuss some of the things that make Mint and Finch different. Finally, we’ll put together a quick project that makes use of Finch to put all of our learning into action. Let’s jump right in!
