Introduction
HarmonyJS is a full-featured NodeJS framework, aimed at creating fast, efficient, scalable and reactive websites and applications.
Built around GraphQL, HarmonyJS is a data-centric framework: the entry point of all code is the data-model, and all development is made around it, not against it.
Philosophy
HarmonyJS relies on established as well as state-of-the-art technologies such as changestreams, websockets and GraphQL to provide amazing performances and an awesome developer experience.
All parts of HarmonyJS are built with stateless-ness in mind, inspired by GraphQL resolvers which are a big part of the core framework. Because of this stateless philosophy, Harmony applications are scalable horizontally out-of-the-box.
Getting started
HarmonyJS is composed of three core packages: @harmonyjs/server, @harmonyjs/persistence and @harmonyjs/query.
- On the server-side,
@harmonyjs/serverprovides the core functionality of a webserver.@harmonyjs/persistencehelps us define and access our data. - On the client-side,
@harmonyjs/queryallows us to write our API calls and subscribe to our data changes.
HarmonyJS packages are standard NPM packages and require no specific CLI whatsoever. Just add them to your project.
