My first open source project (micro check library)
Check types, regexps, presence, time and more...
My first open source project (micro check library) launched on January 28, 2015 with 13 votes and more than 75% of that year's launches. The site was still online in September 2026, 11 years on.
In plain words
This open source library provides validation checks for developers, including type checking, regular expression matching for postal codes and phone numbers, presence validation, and range comparisons. It verifies values against specific formats like Canadian postal codes, social security numbers, and extensible provisioning protocol phone numbers, while also offering utility checks for object properties and browser detection. The tool is designed for developers building applications that require input validation and data verification functionality.

Talanoa▲340Hi 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…
