Serving static files in Express code example

Example 1: node express server static files

var express = require('express');
var app = express();
var path = require('path');

//app.use(express.static(__dirname)); // Current directory is root
app.use(express.static(path.join(__dirname, 'public'))); //  "public" off of current is root

app.listen(80);
console.log('Listening on port 80');

Example 2: express public

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

Example 3: express img folder

app.use(express.static('public'))

Example 4: app.use public

app.use(express.static('public'))
app.use(express.static('files'))

Example 5: use static with expres

app.use(express.static('directoryName'))
#store the files in the directory as if you were making a website without express

Example 6: node js express static folder

// node js -> express -> basic example: static folder, 404 page

const express = require('express');
const path = require('path');
const PORT = process.env.PORT || 5000;

const app = express();

function error404(req, res) {
  res.status(404);

  if (req.accepts('html')) {
    res.sendFile(path.join(__dirname, 'public/errors/404.html'));
    return;
  }

  if (req.accepts('json')) {
    res.send({
      status: 404,
      error: 'Not found'
    });
    return;
  }
  
  res.type('txt').send('404 - Not found');
}

app
  .use(express.static(path.join(__dirname, 'public')))
  .use(error404)
  .listen(PORT, () => console.log(`Listening on ${ PORT }`));
