README.MD This file contains the documentation for the chat-server package in the Easy Chat Library.
This is the documentation for the @easy-chat/chat-server package. It provides functionality for the chat server in the Easy Chat application.
@easy-chat/chat-server implements real-time bidirectional event-based communication. It consists of:
- a Node.js server (this repository)
- a Javascript client library for the browser (or a Node.js client)
Its main features are:
Connections are established even in the presence of:
- proxies and load balancers.
- personal firewall and antivirus software.
For this purpose, it relies on socket io, which first establishes connection to the backend server using the best possible transports.
You do not need to understand the internal structures and operation of websockets and chat systems. All you need to do is call create a room, heck you not need to destroy a room as this is handled intelligently and automatically;
Sample code:
import { EasyChatServer, IsocketConfig } from "@easy-chat/chat-server";
const httpsServer; // your node server instance
const roomStatusInterval = 1000; // logging update interval
const socketConfig: IsocketConfig = {
pingTimeout: 3000,
pingInterval: 5000,
transports: ["websocket"],
allowUpgrades: false,
};
const allowedOrigins = ["https://yourwhitelistapi.com"];
const easyChat = new EasyChatServer(httpsServer, roomStatusInterval, socketConfig);
easyChat.run(allowedOrigins);// with npm
npm install @easy-chat/chat-server
// with yarn
yarn add @easy-chat/chat-serverThe following creates an instance of easyChat.
import { EasyChatServer, IsocketConfig, IchatMsg } from "@easy-chat/chat-server";
const httpsServer; // your node server instance
const roomStatusInterval = 1000; // logging update interval
// the config properties can be optional
const socketConfig: IsocketConfig = {
pingTimeout: 3000,
pingInterval: 5000,
transports: ["websocket"],
allowUpgrades: false,
};
const easyChat = new EasyChatServer(httpsServer, roomStatusInterval, socketConfig);
easyChat.run();
/**
* get data from event incase you
* you want to process it futher,say my be save
* in database or file*/
easyChat.onlineRoom.on("CHAT_MESSAGE", (message: IchatMsg) => {
// do stuffs with message here
});
// for full event list see enum ECHATMETHOD
import { ECHATMETHOD } from "@easy-chat/chat-server";Communication between you and the server are established throught events Below are all events you can listen to;
/**
* get data from event incase you
* you want to process it futher,say my be save
* in database or file*/
easyChat.onlineRoom.on("CHAT_MESSAGE", (message: IchatMsg) => {
// do stuffs with message here
});/**
* get delted message request and id of the message incase you want to remove from database*/
easyChat.onlineRoom.on(
"DELETE_MESSAGE",
({ deleted, id }: { deleted: IchatMsg; id: string }) => {
// do stuffs here
}
);/**
* get update room request*/
import { Chatroom } from "@easy-chat/chat-server";
easyChat.onlineRoom.on(
"UPDATE_ROOM",
({ roomData }: { roomData: Chatroom }) => {
// do stuffs here
}
);import { IpeerInfo } from "@easy-chat/chat-server";
/**
* get update peer request*/
easyChat.onlineRoom.on(
"PEER_UPDATE",
({ peerInfo }: { peerInfo: IpeerInfo }) => {
// do stuffs here
}
);You need to pass the Server to easy-chat, and not the express application function. The rest of the listening is done automatically.
import { EasyChatServer, IsocketConfig } from "@easy-chat/chat-server";
import express from "express";
const app = require("express")();
const httpsServer = require("http").createServer(app);
const roomStatusInterval = 1000; // logging update interval
const socketConfig = {
pingTimeout: 3000,
pingInterval: 5000,
transports: ["websocket"],
allowUpgrades: false,
};
const easyChat = new EasyChatServer(httpsServer, roomStatusInterval, socketConfig);The source code of the website can be found here. Contributions are welcome!
