If you want to build your own blogging app using only HTML, CSS and JS, this tutorial is for you. You will learn how to create a simple but functional blogging app that can display dynamic blog posts, have a dedicated editor for writing blogs, and use Firebase firestore to store and retrieve blog data.
What You Need

To follow this tutorial, you will need:
A code editor of your choice
Node.js and NPM installed on your system
A Firebase account and project
Setting Up the Server
First, we need to set up a Node.js server that will serve our static files and handle file uploads. To do this, follow these steps:
Create a new folder for your project and open it in your code editor
Open a terminal and run npm init to initialize NPM in your project
Install the following packages: express.js, express-fileupload and nodemon
Create a file named server.js in your project root and import the packages
Create a variable named initial_path and store the path to your public folder
Create an express app and use express.static to serve the public folder
Use app.use(fileupload()) to enable file uploads
Create a home route that sends the home.html file from the public folder
Listen on port 3000 and log a message
