I am making a small websocket-based database on Glitch. My testing was working perfectly at first, but when I ran my test and the client reloaded, I received the error message shown above. I tried turning new parts of the code into comments to fix this, but it seems to be a permanent issue. Here is my code:
On the server:`const WebSocket = require(‘ws’);
const wss = new WebSocket.Server({ port: 8080 });
var fs = require(‘fs’);
var data = ;
var i;
function sleep(ms) {
return new Promise(resolve => setTimeout(resolve, ms));
}
function readWriteSync(val) {
var dat = fs.readFileSync(‘stuff.txt’, ‘utf-8’);
var newValue = dat+=val+’ ';
fs.writeFileSync(‘stuff.txt’, newValue, ‘utf-8’);
}
function deleter(){fs.writeFileSync(‘stuff.txt’, ‘’, ‘utf-8’);}
async function reloader(){
fs.writeFileSync(‘reload.txt’, ‘reload’, ‘utf-8’);
await sleep(100);
fs.writeFileSync(‘reload.txt’, ‘’, ‘utf-8’);
}
wss.on(‘connection’, (ws) => {
ws.on(‘message’, (message) => {
console.log(Received message => ${message})
if(message==‘delete’){deleter()}else{
data.push(message);deleter();readWriteSync(message);reloader();}
if(data.length>=10){
for(i=0;i<data.length;i++){
readWriteSync(data[i]);
}
reloader();
}
})
ws.send(fs.readFileSync(‘stuff.txt’, ‘utf-8’));
setInterval(function(){ if(fs.readFileSync(‘reload.txt’, ‘utf-8’)==‘reload’){ws.send(‘reload’)} }, 50);
