Build a Fullstack Blog with Flask

This tutorial will help you build a fully functional blog using Flask as the backend. We’ll cover everything from setting up a database, rendering posts, handling user input, and enabling admin control.

Project Overview

The blog will include features like:

• Homepage with blog post previews
• Detailed post view
• Admin dashboard to create, edit, delete posts
• Categories and tags for filtering

Step 1: Setup Project Structure

project_folder/
├── app.py
├── templates/
│   ├── base.html
│   ├── blog.html
│   ├── post_detail.html
│   └── admin_dashboard.html
├── static/
├── models.py
└── forms.py
    

Step 2: Configure Flask and Database

Set up Flask with SQLAlchemy:

# app.py
from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///blog.db'
db = SQLAlchemy(app)
    

Step 3: Create Post Model

# models.py
class Post(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    title = db.Column(db.String(100), nullable=False)
    content = db.Column(db.Text, nullable=False)
    date_posted = db.Column(db.DateTime, default=datetime.utcnow)
    

Step 4: Design Templates

Use Jinja2 with Tailwind CSS to build your UI. Start with `base.html` for layout and extend it in `blog.html` and `post_detail.html`.

Step 5: Admin Features

Create forms using Flask-WTF to allow admins to add, edit, and delete blog posts. Secure admin routes using login protection.

Step 6: Final Touches

• Add category filtering
• Enable pagination for large blogs
• Include SEO meta tags for better reach
• Deploy on Render or Vercel

Conclusion

With Flask, building a dynamic, full-featured blog is completely achievable. This project also builds skills you’ll need for more complex apps like portfolios, dashboards, or e-commerce sites.
