It stablish a connection between two nodes.

Examples

// Server
const { createNode } = require('dop')
const WebSocket = require('ws')
const wss = new WebSocket.Server({ port: 8080 })
function serverEntryFunction() {
    return {
        login,
        register,
        logout
    }
}
wss.on('connection', ws => {
    const client = createNode()
    client.open(ws.send, serverEntryFunction)
    //...
})

// Client (Browser)
import { createNode } from 'dop'
const ws = new WebSocket('ws://localhost:8080')
const server = createNode()

ws.onopen = async () => {
    const serverEntryFunction = server.open(ws.send)
    // ...
}

Client is not passing an entryFunction as second argument. But both can do it.

// Server
const clientEntryFunction = client.open(
    ws.send,
    function serverEntryFunction() {
        // do some stuff
    }
)

// Client (Browser)
const serverEntryFunction = server.open(
    ws.send,
    function clientEntryFunction() {
        // do some stuff
    }
)
