Tornado Framework for High Performance Web Apps

in

This bad boy is a game-changer in the world of web development, especially if you need your app to run like lightning fast.

So how does it work? Well, let me break it down for ya. Imagine you’re building an online store and you want customers to be able to add items to their cart without any lag time or delays. With Tornado Framework, you can handle multiple requests at once using non-blocking I/O operations. This means that your app won’t freeze up when someone tries to buy a bunch of stuff all at once it just keeps on truckin’.

Here’s an example: let’s say you have a list of products and their prices, and you want customers to be able to add items to their cart by clicking a button. With Tornado Framework, you can create a function that handles the request and updates the cart in real-time without any delays or page refreshes:

from tornado import web
import json

class MainHandler(web.RequestHandler):
    def get(self):
        # Get list of products from database
        products = [{"name": "Product 1", "price": "$9.99"}, {"name": "Product 2", "price": "$14.99"}]
        
        # Render HTML template with product list and add cart button for each item
        self.render("index.html", products=products)
    
    def post(self):
        # Get selected product from form data
        product_id = int(self.get_argument('product')) # get the product id from the form data and convert it to an integer
        
        # Add selected product to cart and update total price in real-time using AJAX
        self.write("Product added to cart!") # write a message to the page to confirm that the product has been added to the cart
    
    def get_cart(self):
        # Get current contents of cart from database or session storage
        items = [{"name": "Product 1", "price": "$9.99"}, {"name": "Product 2", "price": "$14.99"}]
        
        # Render HTML template with cart list and total price calculation using JavaScript
        self.render("cart.html", items=items) # render the cart page with the list of items and use JavaScript to calculate the total price

In this example, we’re using the `get()` function to render an HTML template that displays a list of products and their prices. When a customer clicks on a product, they are redirected to another page where they can add it to their cart using AJAX (without any page refreshes). The `post()` function handles this request by adding the selected item to the cart and updating the total price in real-time.
