kv-demo


Key Value store on top of Upring demo.

See ./bin.js for exposing upring-kv over HTTP.
This file contains a small http API to get/put data into the
key-value store. Each URL equals to a given key.

To use is, follow these instructions. First, install some
dependencies:

``
npm i kv-demo pino baseswim -g
`

Then, we need to figure out what is our ip.

On Linux:

`sh
export MYIP=ip addr show wlan0 | grep -Po 'inet \K[\d.]+'
`

On Mac:

`sh
export MYIP=ipconfig getifaddr en0
`

The export phase needs to be done for every opened shell.

Then we can start our upring cluster. We will use a
baseswim node to simplify bootstrapping.

`sh


on one shell

baseswim --host $MYIP --port 7979 | pino

on another shell

upring-kv -p 3042 $MYIP:7979 | pino

on another shell

upring-kv -p 3043 $MYIP:7979 | pino

on another shell

upring-kv -p 3044 $MYIP:7979 | pino
`

Then we can query our key/value storage using basic curl.

`
curl -v localhost:3042
curl -X POST -d 'hello upring' localhost:3043
curl -v localhost:3044


on another shell

curl localhost:3042?live=true # use SSE to send updates

one more shell

curl -X POST -d 'by Matteo' localhost:3043
``
