Connection Manager
Maintaining connection state is a royal pain in the behind. This utility class takes a connect() method and:
- Only call it to create a connection when needed
- Automatically retry on failure
- Automatically reconnect if the previous connection was closed
- Properly handle shutdown sequence
Usage
const conMgr = new ConnectionManager({
async connect() {
//...
return connection
},
retryDelay: 10*1000
})
//wherever you need the connection
const connection = await conMgr.get()
//shutdown
conMgr.shutdown()
