I am grouping my files like so:
I've already required those:
const express = require('express');
const app = express();
const path = require('path')
what do I do next?
I assume that you're somewhat of a beginner with Node/Express.
I recommend you learn more about how express works before deploying this into an actual app.
Let's get something straight: I believe that you only have a group of HTML files that you want to show to the user under the file names eg. example.com/about.html with the homepage HTML file being called index.html so that express knows what to show where.
This is the simplest way I could think i'd achieve this effect.
const express = require('express');
const app = express();
const path = require('path');
// This is the port where the application is running on
// Uses the server's enviroment variable named PORT if is defined else
// this will use port 5000
// the page can be seen locally at http://localhost:5000/
const PORT = process.env.PORT || 5000;
// This line makes the app created earlier use the middleware that express provides for "rendering" static files
// inside the express.static method we give a path to the static files
// to create that path we use the path.join method provided by the path module we imported earlier
// this method takes in all the paths that need to be joined.
// the __dirname is the directory the application was launced from (you can use process.cwd() to get the root)
// and ofcourse the structures is the folder which contains all your HTML files
app.use(express.static(path.join(__dirname, "structures")));
// Now we do the same thing we did before but we add the middleware for the styles under the "/styles" URI.
app.use("/styles", express.static(path.join(__dirname, "styles")));
// This will start the server at the PORT which we defined earlier.
app.listen(PORT);
