Server.js
var restify=require('restify')
const { logIn,userCreation, demotable } = require('./routes/Function');
const corsMiddleware = require('restify-cors-middleware2');
const { data } = require('jquery');
const PORT=process.env.PORT || 8080;
var path=require('path')
var server=restify.createServer() //server created
server.use(
function crossOrigin(req,res,next){
res.header("Access-Control-Allow-Origin", "*");
res.setHeader('Access-Control-Allow-Headers', 'Content-Type');
res.setHeader('Access-Control-Allow-Credentials', true); // If needed
res.header("Access-Control-Allow-Origin", "*");
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
return next();
}
);
const cors = corsMiddleware({
preflightMaxAge: 5, //Optional
origins: ['*'],
allowHeaders: ['*'],
exposeHeaders: ['*']
})
server.pre(cors.preflight)
server.use(cors.actual)
//setting
// if (process.env.NODE_ENV === "production") {
// //server static content
// //npm run build
// server.use(restify.static(path.join(__dirname, "client/build")));
// }
console.log(__dirname);
console.log(path.join(__dirname, "client/build"));
//get data from login form
server.post('/note', userCreation);
server.use(restify.plugins.bodyParser());
server.get('/login',logIn)
server.get('/employees',demotable)
if(process.env.NODE_ENV==='production')
{
server.get('/client/build/*', restify.plugins.serveStatic({
directory: __dirname,
default: 'index.html'
}));
// server.use(restify.serveStatic('client/build'))
// server.get('*',(req,res)=>{
// res.sendFile(path.join(__dirname,'client','build','index.html'))
// })
}
// server.get("*", (req, res) => {
// res.sendFile(path.join(__dirname, "client/build/index.html"));
// });
server.listen(PORT, function(){
console.log("server started...")
})

You should put the "start": "node server.js" inside the scripts section like
"scripts": {
"start": "node server.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
