What about
const express = require("express");
const app = express();
app.get("/", (req, res) => {
res.send("Hello from OpenBSD");
});
app.listen(80, (err) => {
if (err) {
console.log("Something went wrong: ");
} else {
console.log("Server started on port 80");
}
});
or something like that? Your app seems to ignore all possible errors, one of
which might be that it can't bind to port 80.
Alternatively try to bind to port 3000 and see if that changes things.
