Ask HN: What are some tools / libraries you built yourself?
I've created a simple typescript library for generating QR payment strings, which can then be encoded into an actual QR payment. The actual standard for such payments is called SPAYD and it's accepted in most of our contry's bank apps.
Initially, I needed to create such QR and hadn't found any publicly available web tool, so I created one by myself.

Ask HN: What are some tools / libraries you built yourself?
I build a logging library for Go, because I couldn't find one that logs to stdout AND stderr. If you used a logging lib on GCP for example, all log output went into the same pile of junk and it was hard to find "real" errors: https://github.com/emvi/logbuch
Then there is "null", also because I couldn't find one that got both, marshalling to JSON and be able to store null values in db: https://github.com/emvi/null
And finally, our "flagship" open-source project Pirsch, an embedded library for web analytics: https://github.com/pirsch-analytics/pirsch
