Hyperlocal context (HLC) server combining all the core open source software packages of the reelyActive stack for convenience and ease of exploration of features and applications. Observe who/what is where/how, in real time, in any physical space. Just add radio infrastructure (ex: RFID readers, Raspberry Pi, ...) for source data.
Getting Started Tutorials
The easiest way to get started with hlc-server:
Installation and Quick Start
Using git and npm
git clone https://github.com/reelyactive/hlc-server.git cd hlc-server npm install
Add then to run:
docker run -p 3001:3001 -p 50000:50000/udp -p 50001:50001/udp reelyactive/hlc-server
Hello Hyperlocal Context
Browse to localhost:3001 to see the landing page.
hlc-server will listen for data as follows:
- reel packets over UDP on port 50000 (via barnowl-reel UdpListener)
- encoded raddecs over UDP on port 50001
hlc-server will output data as follows:
- socket.io stream on port 3001 (via barnacles-socketio)
- decoded raddecs to Elasticsearch, if an instance is running (by default on port 9200)
A variety of web apps designed to make it easy to familiarise oneself with the many platform features and capabilities can be accessed via the landing page at localhost:3001. These web apps are built with the open source beacorcut stack of beaver.js, cormorant.js and cuttlefish.js.
Note that the integration of some open source software packages with hlc-server is still a work in progress.
hlc-server observes the following environment variables:
|PORT||3001||The hlc-server port|
|REEL_PORT||50000||The port on which to listen for reel packets over UDP|
|RADDEC_PORT||50001||The port on which to listen for raddecs over UDP|
|ELASTICSEARCH_NODE||http://localhost:9200||The Elasticsearch node|
Add listeners and interfaces
Add any barnowl-x listener to connect with a hardware interface in just two lines of code. For example, to listen for reel data over a serial connection:
const HLCServer = ;const BarnowlReel = ; // 1: Include the interface packagelet app = ;// 2: Add the specific listener with relevant optionsapp;
Add any barnacles-x interface to distribute the data stream in just two lines of code. For example, to forward data via a webhook:
const HLCServer = ;const BarnaclesWebhook = ; // 1: Include the packagelet app = ;// 2: Add the interface with relevant optionsapp;
The v1.0 release of hlc-server is a work in progress as the v1.0 releases of barnowl, barnacles, chickadee, barterer, beaver, cormorant and cuttlefish evolve and/or become available. The objective is to combine all these ingredients required for hyperlocal context in a user-friendly deploy-anywhere package/container that promotes discovery and experimentation.
