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:

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

On Mac:

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.

# 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
