Loglayer: A fluid logging interface for JavaScript loggers
This has been in use on our production systems for around two years now at Switchboard (https://switchboard.app). The problem we had was that we were using two different logging libs for our frontend and backend at the time (specifically roarr, and bunyan), and the API for the logging libs were not compatible with each other. Loglayer was designed to wrap around popular JS logging libraries where you can swap out any underlying library without re-writing your log entries to adapt to the new library. One common example is using plain "console" as a starting integration, but later…

LogLayer – Unified logger that routes logs to various logging libraries2025 · loglayer.dev · ▲56As a longtime TypeScript/Node.js developer, I've often faced challenges with logging—choosing, using, and maintaining the right logger for various projects. While most loggers offer the usual methods like "info", "warn", and "error", they vary significantly in how they handle structured metadata or Error objects. This can lead to ad-hoc solutions, like serializing errors or writing custom pipelines, just to get logs formatted correctly. I built LogLayer to address these pain points by introducing a fluid, expressive API. With methods like "withMetadata" and "withError", LogLayer…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
