Scraper to scrap websites & mobile apps with no web interface
Almost all the websites are using DOM manipulation and Dynamic content. A generic scraper script can’t access the data from these websites and moreover, the APIs serving these websites can’t be scraped directly unless the dynamically generated security token is passed on to the server, the request header. Captcha is the show-stopper for scrapers and bad news is that almost all the websites have captcha enabled for the suspicious requests.

Benefits of building a PWA app
Progressive
One of the core features of PWA is its progressive enhancement, which enables the app to run on any device and supports all browsers. PWA offers enhancement over the existing web technology.
Overcome network issues
One of the most significant advantages of PWA is that it works efficiently at low internet speed and consumes less data as compared to the native counterpart. It provides users with glitch-free user-experience and even works offline.
Improved engagement
Without a doubt, PWA delivers better engagement as compared to native mobile apps as these apps load very fast and delivers amazing performance. PWA also supports push notifications for better user engagement.

We are at the forefront of building Progressive Web Applications
Building a streaming PWA using Angular 7

The interpreter can be in any remote location and can listen to direct feedthrough real-time broadcasting of the presenter feed.
The PWA app offers the user to listen to live streams. The PWA app provides various types of integrations, such as sockets that provide seamless integration of the PWA app with the whole system.
The PWA app also offers some offline data available to users, such as which session they attended, streaming duration, etc.

Our team of PWA developers is skilled in all PWA components
We have a highly experienced team of PWA developers who are skilled in all the components that help in building a Progressive Web Application.
Application Shell Architecture
To build and maintain a PWA, it is required to separate static content from the dynamic content. So, we use application shell architecture. The app shell consists of core design elements that are required to run an application even without an active connection. The app shell approach works really well for JavaScript-heavy apps.
Service Worker
Service worker supports the offline work mode, push notifications, and background synchronization. It is just a JavaScript file run by the browser separately from the app/web page. The service worker responds to user interactions and handles network requests.
Web-App Manifest
It is a JSON file that gives PWA the appearance of a native app. Using manifest, we control as to how the app is displayed to the user and how the app has to be launched. The manifest file using contains app full name and short name, starting URL, links to icons, splash screen, etc.
Transport Layer Security (TLS)
TLS is a standard of robust and secure data exchanges between two applications. To maintain the integrity of the data, it is required to serve the website via HTTPS and installing an SSL certificate on the server. Progressive Web Applications leverages the power of the TLS protocol.
