A batteries included NodeJS API Kickstater focused on extensability
This is a project based on NodeJS and Koa (and some other libs) implementing a REST API to authenticate users and let them manage TODOs stored in a PostgreSQL database. It's easy to extend and provides you the best developer experience possible with a lot of nifty things already configured. It's meant to be used with a front-end consuming the API like a mobile app or a SPA built with for example React, Angular or Vue.
Scalable Language API (SLAPI) The most comprehensive architecture for conversational natural-language applications including speech recognition/synthesis, semantics, & machine translation. Used on Android & other mobile app platforms.
