Content of the file:

let express = require("express");
let app = express();

app.get("/", function(req, res) {
        res.render("./index.html");
});

app.get("/somepage", function(req, res) {
        res.render("./somePage.html");
});

app.listen(3000);

Listing of the directory:

vitalkanev@vitalkanev-HP:~/siteData/expressors$ ls
data.js  views

Operating System: Lubuntu Zesty
Node version: 8.4.0
NPM version: 5.3.0, as comes with the Node version above

Try this

npm install ejs --save
npm install path --save

Add this to your app.js(express js file)

var path = require('path');
app.set('views', path.join(__dirname, 'views'));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');

OR this one liner will work

app.use(express.static(__dirname + '/public'));

Next time please use Stackoverflow before posting a issue here 😄

There is a usability issue here, though: it looks like @vitalkanev may have installed the module html, but since that module is not an Express template module, it causes this odd error. The error can be made better, though.
