    I think its possible that the exphbs function is not properly installed or imported:

      npm install express-handlebars

    Import it with:

      const exphbs  = require('express-handlebars');

    If that’s not the case, and you have it installed and imported correctly. Then see if updating to the latest version fixes the issue:

      npm update express-handlebars

    EDIT: Now that I think about it, you need to call the engine() function on exphbs to get the actual function that you can use to register the handlebars templating engine with your Express app.

    The correct code should be:

      const express = require('express')
  const exphbs = require("express-handlebars");
  const path = require("path");
  const app = express()
  const port = 3000

  app.engine("handlebars", exphbs.engine());
  app.set("view engine", "handlebars");

    exphbs isn’t a function, it is an object of stuff exported by handlebars (see the documentation). The function you want to use is exphbs.engine() like this:

    app.engine("handlebars", exphbs.engine());

    Alternatively, you can destructure the object and take out engine directly:

    const express = require('express')
const { engine } = require("express-handlebars");
const path = require("path");
const app = express()
const port = 3000

app.engine("handlebars", engine());
app.set("view engine", "handlebars");
