GO STREAMING

• Recieve data from Redis Pub/sub, then push data to client.
• Should separate redis to improve performance
• Support SSE and WEBSOCKET

Library:

• gin: https://github.com/gin-gonic/gin
• redis pub/sub: https://github.com/go-redis/redis/v8
• websocket: https://github.com/gorilla/websocket
• broadcast: https://github.com/dustin/go-broadcast

MODEL

[PROCESSING] -> [REDIS PUB/SUB] -> [GO-REDIS-STREAMING] -> [CLIENT]

CONFIG

• port: port streaming service listener
• redis: config redis pubsub
  • host: Host redis
  • port: Port redis
  • db: Database
  • password: Password

{
    "port": "8080",
    "redis": {
        "host": "localhost",
        "port": "6379",
        "db": "15",
        "password": "password"
    }
}

INFO

• / : Get service info
• /admin : Get sse service info

SSE STREAMING

• /streaming/:path/:channel : get sse streaming by path and channel
• Example:
  • /streaming/price/AAPL,IBM -> recieve data from redis pub/sub: price:AAPL and price:IBM
  • /streaming/account/AAPL,IBM -> recieve data from redis pub/sub: account:AAPL and account:IBM

WS STREAMING

• /ws-streaming/:path/:channel : get sse streaming by path and channel
• Example:
  • /ws-streaming/price/AAPL,IBM -> recieve data from redis pub/sub: price:AAPL and price:IBM
  • /ws-streaming/account/AAPL,IBM -> recieve data from redis pub/sub: account:AAPL and account:IBM

TESTING

• Install package wscat

npm install -g wscat

• Run Websocket on terminal

wscat -c wss://localhost:8080/ws-streaming/price/AAPL,IBM

• Run Curl SSE on terminal

curl http://localhost:8080/streaming/price/AAPL,IBM
