I initialized a server in nodeJS and I need to instantiate it. How do I do it?
//Defines logic about the server
const express = require('express')
const health = require('./routes/healthChecker.routes')
const app = express();
app.use(express.json());
app.use('/health', health)
const port = process.env.PORT || 3000
app.listen(3000, () => {
console.log(`Listening on port ${port}`)
})
