Architecture Overview

This overview is 3+ years old. A lot has changed, moved and is being completely reworked in 0.20.
File | Description |
---|---|
red / red.js | The main entry point for Node-RED. Provides the programmatic API into the runtime. |
red / ui.js | Creates the basic express app that serves the UI and related REST endpoints. |
red / server.js | The heart of the runtime. Adds runtime API endpoints to the express app created by ui.js . Provides start /stop functions for the runtime. |
red / events.js | A singleton event-emitter for broadcasting events through-out the runtime. |
red / comms.js | Provides a WebSocket endpoint for real-time communication with the editor UI. |
red / library.js | Provides Flow Library and generic node-type library (e.g. Functions, Templates) functionality. |
red / log.js | Centralised log handling for the runtime and nodes. |
red / storage / index.js | Pluggable storage system for the runtime. |
red / storage / localfilesystem.js | Default storage plugin for the local file system. |
red / nodes / index.js | Entry point into the nodes API. |
red / nodes / Node.js | The class prototype all runtime nodes extend. |
red / nodes / registry.js | The registry of all node types. Responsible for discovering the installed nodes and loading them into the runtime. |
red / nodes / flows.js | Takes the requested flow configuration and instantiates/starts/stops it. |
red / nodes / credentials.js | Provides an api to the credential system for load/add/get/delete functionality. |
