Horizon是一個用JavaScript開發的開源實時應用程序後臺。
使用一個簡單的JavaScript API快速構建和部署Web或移動應用程序，將您的應用程序擴展到數以百萬計的用戶而沒有任何後端代碼。
由rethinkdb團隊和開源社區的貢獻保駕護航，讓你以閃電般的速度建立複雜的應用程序。
Horizon is built on top of RethinkDB and consists of four components:
- Horizon server -- a middleware server that connects to/is built on top of RethinkDB, and exposes a simple API/protocol to front-end applications.
- Horizon client library -- a JavaScript client library that wraps Horizon server's protocol in a convenient API for front-end developers.
- Horizon CLI -
hz-- a command-line tool aiding in scaffolding, development, and deployment - GraphQL support -- the server will have a GraphQL adapter so anyone can get started building React/Relay apps without writing any backend code at the beginning. This will not ship in v1, but we'll follow up with a GraphQL adapter quickly after launch.
Horizon currently has all the following services available to developers:
![:white_check_mark:]()
Subscribe --
a streaming API for building realtime apps directly from the browser without writing any backend code.![:white_check_mark:]()
Auth --
an authentication API that connects to common auth providers (e.g. Facebook, Google, GitHub).![:white_check_mark:]()
Identity --
an API for listing and manipulating user accounts.![:white_check_mark:]()
Permissions --
a security model that allows the developer to protect data from unauthorized access.
Upcoming versions of Horizon will likely expose the following additional services:
- Session management -- manage browser session and session information.
- Geolocation -- an API that makes it very easy to build location-aware apps.
- Presence -- an API for detecting presence information for a given user and sharing it with others.
- Plugins -- a system for extending Horizon with user-defined services in a consistent, discoverable way.
- Backend -- an API/protocol to integrate custom backend code with Horizon server/client-libraries.
