Express.js App scenarios to Serve Static Files from Nested Directory on Heroku
Can someone help me understand I've been working on this all day and I've looked through the documentation and I'm still confused about I'm deploying an Express.js application on Heroku, and I'm having trouble serving static files from a nested directory. My project structure looks like this: ``` my-app/ ├── server.js └── public/ └── assets/ ├── css/ │ └── styles.css └── js/ └── app.js ``` In my `server.js` file, I have the following configuration: ```javascript const express = require('express'); const path = require('path'); const app = express(); app.use(express.static(path.join(__dirname, 'public'))); app.get('/', (req, res) => { res.sendFile(path.join(__dirname, 'public', 'index.html')); }); const PORT = process.env.PORT || 3000; app.listen(PORT, () => { console.log(`Server is running on port ${PORT}`); }); ``` Locally, everything works perfectly, and I can access the CSS and JS files without issues. However, once I deploy to Heroku, the browser console shows 404 errors for the static files. The specific behavior message is: ``` GET https://my-heroku-app.herokuapp.com/assets/css/styles.css 404 (Not Found) ``` I’ve confirmed that the files are indeed present in the Heroku environment by checking the build logs, and I've already set the buildpack to Node.js. I've tried moving the files directly under the `public` directory as well as adjusting the path with no success. I've also ensured that there are no discrepancies in file names and that there are no case sensitivity issues, as Heroku runs on a case-sensitive filesystem. I've looked into using `express.static` with different configurations, and nothing seems to resolve the scenario. Has anyone faced a similar question or can point out what I might be missing in my setup? Any insights would be appreciated! I've been using Javascript for about a year now. Any feedback is welcome! I'm working in a CentOS environment. Has anyone else encountered this?
