What is Bootstrap

In a single sentence, Bootstrap helps us to code faster and easier user interfaces by providing a set of HTML, and CSS templates for creating UI components like buttons, dropdowns, forms, alerts, modals, tabs, accordions, etc. Reusing the assets provided by the Bootstrap framework we might win time and also improve the quality of our end-product. Why using Bootstrap:

  • Easy to use - any developer with basic programming knowledge can use and combine Bootstrap components to prototype fast a web page.
  • Responsiveness - Bootstrap components are built to adapt and display properly on desktop and mobile devices with a wide range of resolutions.
  • Alive Community - this amazing framework is actively supported and versioned by a huge open-source community
  • Cross-Browser Compatibility - Bootstrap keeps up the codebase with the latest standards for a smooth deployment on all well-known browsers: Chrome, Safari, IE, or Firefox.

What is Flask

Flask is an open-source web framework coded in Python using a lightweight codebase and flexible by design. By default, Flask is not coming with a database or any other hard dependency empowering the developers with total freedom in terms of used modules and how to structure the project. To use Flask and code a test application, Python3 should be properly installed in the workstation and accessible in the terminal window.

$ pip install flask
Flask - Install via PIP

The above command install Flask using PIP, the official package manager for Python. Once Flask is installed, we can code a simple app and run it:

from flask import Flask 
app = Flask(__name__) 
 
@app.route('/') 
def hello_world(): 
    return 'Flask & Boostrap works great!' 
 
if __name__ == '__main__': 
    app.run() 
Flask - Simple App

If we execute the above snippet and open http://localhost:5000 in the browser we should see the message Flask & Boostrap works great. Even if not too much, we've just coded a usable Flask application that we can improve with more features and modules.

For more than a simple Hello World let's get back to our list.
