I've been looking at responses on here for this question, but nothing has helped me. Some solutions have given me even more errors, too.

What I am trying to do is route to different pages with Node.JS. Having learnt a little bit on the MEAN stack, I decided to use Node, Express, and Angular (haven't gotten there yet). If I try to to to any place that isn't the '/' route, I get an error saying 'Cannot find module 'html'. Below is the code in question:

//dependencies
var express = require('express');
var path = require('path');
var engines = require('consolidate')

//variables
var RUN_PORT = 8080;
var VIDEO_IN_PORT = 45679;
var CONTROL_OUT = 45678;
var app = express();

app.use(express.static(path.join(__dirname, 'public')));

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

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

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

//showing that the program is running on the RUN_PORT
app.listen(RUN_PORT, function(){
    console.log("Running on port " + RUN_PORT);
});

What am I not seeing here? Everything seems to look fine. All I have installed in my package.json is Express. I am able to get to the index page just fine, but anything other than that causes that error.

The issue is caused by using res.render('SOMEFILE.html'), because you're not telling Express how to render files with a .html extension.

Since you're not using any templating (yet), you can use this:

// Somewhere at the top:
const path  = require('path');
const VIEWS = path.join(__dirname, 'views');
...

// In your route handlers:
res.sendFile('index.html', { root : VIEWS });

When you want to start using templating, look here: http://expressjs./en/guide/using-template-engines.html
