I got successfully my websocket up and running but I need to use the .send() method on my route.
I got my app split on several files. In this case I got:
app.js
//..some other code..
//Server
const server = http.createServer(app)
var port = process.env.PORT || 80;
const connection = server.listen(port, () => {
console.log('Listening on ' + port);
});
const WebSocketServer = require("ws").Server;
const wss = new WebSocketServer({
server
});
//Here I need to export the wss
module.exports.sengMsg = function (msg, callback) {
return wss.on("connection", function (ws) {
ws.send(msg, callback);
ws.on("close", function () {
console.log("websocket connection close")
})
})
};
api.js
//..some other code..
var sendMsg = require('../app').sendMsg;
router.get('/', (req, res) => {
sendMsg('Hi I from default route', (err)=>{
console.log("I got some error on ws");
})
res.send('Welcome to my API');
})
But in the end I come up with
TypeError: sendMsg is not a function
What is the recommended way to export the funcionality of my wss on my routes using this setup ?
Try changing the code to,
var sendMsg = require('./app');
router.get('/', (req, res) => {
sendMsg.sendMsg('Hi I from default route', (err)=>{
console.log("I got some error on ws");
})
res.send('Welcome to my API');
})
or change the app.js module.exports to following,
module.exports = {
sendMessage :function (msg, callback) {
return wss.on("connection", function (ws) {
ws.send(msg, callback);
ws.on("close", function () {
console.log("websocket connection close")
})
})
}
}
