What steps are needed to set up my Express server so that it can render all my content, rather than just my HTML file?

I need help setting up a server for my project using Express. Here is the structure of my file directory:

root-directory
├── public
│   ├── css
│   │   └── styles.css
│   ├── images
│   │   └── img1.png
|   |   └── img2.png
|   |   └── img3.png
│   └── index.html
|   └── main.js
└── server
    └── app.js

This is my current server code:

const express = require('express');
const path = require('path');

const app = express();
app.use('/static', express.static('public'));
app.use(express.json());

app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname, '../public/index.html'))
});

const port = 5000;
app.listen(port, () => console.log(`Server is listening on port ${port}.`))

Right now, only the static HTML file is being displayed by the server, and not the linked CSS or JavaScript files. I tried modifying the sendFile function to

res.sendFile(path.join(__dirname, '../public'))
, but I received an Error: Cannot GET /.

How can I adjust my server configuration to showcase all HTML, CSS, and JavaScript content simultaneously?

Answer №1

  • First and foremost, it is advised to remove the following block of code:
app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname, '../public/index.html'))
});

Responding to all GET requests with the index.html file due to the use of '*' may not be necessary. Additionally, this conflicts with the line

app.use('/static', express.static('public'));
.

  • Secondly, make sure to replace /static in the aforementioned line with /
app.use('/static', express.static('public'));

This change will enable your app to locate the index.html in the public folder when responding to the GET '/' request.

  • Lastly, verify that all links in your index.html file for CSS/JS/image files are correct. For example, the link to the style.css file should be:
    <link rel="stylesheet" href="/css/style.css">
    .
