Overview of this book

When used effectively, deep learning techniques can help you develop intelligent web apps. In this book, you'll cover the latest tools and technological practices that are being used to implement deep learning in web development using Python. Starting with the fundamentals of machine learning, you'll focus on DL and the basics of neural networks, including common variants such as convolutional neural networks (CNNs). You'll learn how to integrate them into websites with the frontends of different standard web tech stacks. The book then helps you gain practical experience of developing a deep learning-enabled web app using Python libraries such as Django and Flask by creating RESTful APIs for custom models. Later, you'll explore how to set up a cloud environment for deep learning-based web deployments on Google Cloud and Amazon Web Services (AWS). Next, you'll learn how to use Microsoft's intelligent Emotion API, which can detect a person's emotions through a picture of their face. You'll also get to grips with deploying real-world websites, in addition to learning how to secure websites using reCAPTCHA and Cloudflare. Finally, you'll use NLP to integrate a voice UX through Dialogflow on your web pages. By the end of this book, you'll have learned how to deploy intelligent web apps and websites with the help of effective tools and practices.

Summary

Using ngrok to facilitate HTTPS APIs on localhost

You will need to create your own order management system API for the cloud function script to work so that it can fetch the order status from the API. You can find a quick sample at http://tiny.cc/omsapi. Your API must run on an HTTPS URL. To achieve this, you can use services such as PythonAnywhere and ngrok. While PythonAnywhere hosts your code on their servers and provides a fixed URL, ngrok can be installed and run locally to provide a forwarding address to localhost.

Say you have to run your Django project for the order management API on port 8000 of your system and now wish to provide an HTTPS URL so that you can test it; you can do so easily with ngrok by following these steps:
