Show HN: Simple pub/sub using WebSockets in Node.js I built this pubsub module because I wanted a simple solution that uses only node. Why did I want pubsub? I wanted to build a complex app but segregate it into microservices that work together through event messages. I also wanted to use this method instead of node's built-in clustering for multiple instances. I've been running it for a few weeks now with several messages per second bugfree. I plan to use this setup for future apps as it reduces complexity of the code and allows me to restart/update one part of the app without interrupting the other parts. I would love to receive feedback and suggestions on the code and features, and hope it can be useful to you also! https://ift.tt/hN7tbjU December 16, 2022 at 07:36PM
Show HN: StreetComplete, an OpenStreetMap Editor for Humans StreetComplete is an OpenStreetMap[0] editor directed at people who want to contribute and want to do this using their smartphone, without learning how to edit things[1]. It is available as an Android application. It is intended to be used as one walks, with quests appearing as markers on the map. Selecting a marker allows one to answer a simple question. The answer will be added to the OpenStreetMap database, with app handling selecting objects for editing, transforming answer into OSM tags and making edits. OpenStreetMap account is needed to apply edits, but it is possible to start without it, make some edits and login/register later. Note: I am not the main author, but I am one of the active contributors. Github page is at https://ift.tt/2g8lasH and https://ift.tt/3nR9PzS shows what was recently released.
