PostgREST vs ReactiveMongo: What are the differences?
PostgREST: Automatic REST API for Any Postgres Database. PostgREST serves a fully RESTful API from any existing PostgreSQL database. It provides a cleaner, more standards-compliant, faster API than you are likely to write from scratch; ReactiveMongo: Non-blocking, Reactive MongoDB Driver for Scala. ReactiveMongo is designed to avoid any kind of blocking request. Every operation returns immediately, freeing the running thread and resuming execution when it is over. Accessing the database is not a bottleneck anymore.
PostgREST and ReactiveMongo belong to "Database Tools" category of the tech stack.
PostgREST and ReactiveMongo are both open source tools. PostgREST with 12.5K GitHub stars and 585 forks on GitHub appears to be more popular than ReactiveMongo with 797 GitHub stars and 231 GitHub forks.
