Node/Express: $ symbol not recognising the input PORT 8080

Question

How can I get my PORT running on 8080? Do I need to install a dependency?

const app = require('express')();
const PORT = 8080;

app.listen(
    PORT,
    () => console.log('its alive on http://localhost:${PORT}')
)

Terminal: API % node . its alive on http://localhost: ${PORT}

Answer 1

Since you are using template literals you need to write it as

const PORT = 8080;

app.listen(
    PORT,
    () => console.log(`its alive on http://localhost:${PORT}`)
)
