Bubbling UP Error details in Node.js

Posted on August 21, 2024 | Marc Andreu

The problem: We want to propagate some error details from the internal modules to the front end or to the API exposed to our code’s users. One common method of propagating the error is passing it as the second parameter of the error constructor. However, obtaining the error details requires specific syntax. The solution: In Node.js, the Error object can propagate the cause property inside the options argument. As an example, let’s say we have the function getUsers that fetches a list of users, and another module consumes that function to generate the list of elements on the UI. [Read More]

Optimal NodeJS DevContainer Package Management

Posted on July 16, 2024 | Marc Andreu

The problem: Each dev container that uses Npm or Yarn as package managers has to download all the “node_modules”, plus some transient ones, for each container where those files take quite a lot of disk space and time to download. The Solution: Set up a dev container with Pnpm and a global shared packages store with the host system. This approach eliminates the need to duplicate files. It saves significant network resources and time by reusing all the files that other dev containers or the host machine have already downloaded into the global store. [Read More]

Overcoming Git Credential Issues in VSCode Dev Containers We developers should work in isolated environments to maintain consistency across different machines and team members. Visual Studio Code’s dev containers are a fantastic tool, providing an automated method to consistently spin up a development environment regardless of the host machine. However, when working with private repositories, you might encounter a common hurdle: accessing your Git credentials within the dev container. The Problem: Missing Git Credentials in Dev Containers Picture this scenario: You’re diligently coding away in your VSCode dev container, feeling productive and in the zone. [Read More]

The basics of Software Quality

Posted on January 25, 2022 | Marc Andreu

The “Who should do QA” podcast is one of the best podcasts about Software Quality I have found so far. I became a regular listener to the Test & Code show by Brian Okken. Episode 175 is one of the finest synopses about the quality practices to perform as a top software development team. Brian presents the ideas from a reflective style as a practical developer, making the concepts more engaging than QA biased content. [Read More]
