A fast, unopinionated, minimalist web framework for Node.js

Observability vs. monitoring is not an either-or proposition. Observability has certainly evolved from monitoring, but has taken a big step forward. Based on the telemetry data, monitoring tells you what’s wrong whereas observability tells you why something is wrong. In this article, I explore observability from an application developer perspective, focusing on what challenges developers might be facing. I also show how we can simplify and streamline the work, with an enterprise-grade full-stack observability platform, like Instana, which is a key product in IBM’s AIOps platform.

This articles covers why you should use ESLint for linting Node.js packages -- and how to use ESLint.

Get the quick tips and tricks you need to use ESLint to autofix and format your JavaScript.

Develop applications that are resilient to temporary network blips. You'll use retry logic in a Redis client library to illustrate the steps you can take to design a self-healing connection to a persistent data store or a cache.

Discover how running tests in parallel mode under Node.js allows Mocha to take advantage of multicore CPUs, resulting in significant speedups for large test suites.

Learn best practices for managing memory in container-based Node.js applications.

If you already have an internal IT infrastructure, it quite likely contains an LDAP server (possibly Active Directory, acting as an LDAP server) to serve user identities. In many cases, it is best to continue to use that directory, even when your application sits in IBM Cloud. In this tutorial, I show you how to authenticate users.
