Creating the server
Initialize a server on port 8082:
const realjs = require("real.js");
const Server = new realjs.RealTimeServer({ port: 8082 });
Server.on("connection", () => console.log("New client"));
Send a message event to a new client
You can send any dictionary with primitive types to the client.
Server.on("connection", client => {
// send message to new client
Server.publish(client, "message", {
myCustomAction: "new_user",
message: "New user connected"
});
});
Send a message event to all connected clients
Server.on("connection", client => {
// send message to all clients
Server.publishAll("message", {
myCustomAction: "new_user",
message: "New user connected"
});
});
Events are user-defined
We can send a newUser event on a new connection
Server.on("connection", client => {
// send message to all clients
Server.publishAll("newUser", {
detail: "New user connected"
});
});
