What are PWA and What problems do they solve?
Let’s discuss the well-known phone app, Whatsapp. When using this app, if there is no cellular, you will still be able to open the application, check past messages and even send a message to somebody.
When you finally get connected back to wifi or the internet, all of your messages will automatically be sent through.
Progressive Web App (PWA) is a name used to signify a new software development methodology. Compared to customary applications, progressive web apps are a hybrid of standard site pages (or sites) and that of a mobile application. This new application model endeavors to join the highlights offered by most contemporary browsers, with the advantages of an exceptional mobile experience.
Why we need PWAs and what are their highlights?
- PWAs are extremely reliable! PWAs load in a split second and never demonstrate the infamous ‘downasaur’ (indicating the internet is ‘down’), even in the most unreliable network conditions.
Additionally, they’re very quick, responding rapidly to user interactions with seamless animations and fluid interactions.
They’re engaging to such a degree that they feel like a natural application on your gadget, offering a vivid client experience.
- There’s no downloading required! PWAs open directly through a browser just like a website. For the ability to quickly open it up later, the PWA can be added to the home screen with a single click. As a result, an icon shows up right on the user’s screen, which enhances your brand recognition. Eliminating the need for a user to download anything from an application store means that ultimately there are fewer steps required before being able to use the PWA.
- Push Notifications: A PWA can send push notifications to its users. This enables providers to alert users periodically, thus ensuring that they do not forget about your progressive web application and use it more frequently. This also ensures that the user will become familiar with push notification and find it an easy way to stay informed above any changes or updates on the App
- A single code for every mobile platform: compared to the Android/iOS local programming apps, where the code is made separately for every stage, PWAs make a solitary code base utilizing JS, HTML, and CSS. This ultimately prompts a decrease in the overall general spending plan of the application.
- Furthermore, there’s no need to upload your application to the App Store or Google Play! Also, you don’t need to give commercial centers a percentage of your income and you won’t be restricted by guidelines.
- Enhanced security: a PWA works with the same security protocols as a regular website. Hence, it is easy to connect the SSL certificate, which is the most secure solution for practicing reliable communication with the server.
- If there is a poor or no Internet connection whatsoever, a normal website or app won’t load and clients can’t interact with it. PWAs, however, aren’t restricted and can work offline because of their unique ability to utilize stored information from past online exercises. For instance, say you have an online store; a user can continue glancing through your product pages after the Internet disconnects. Having an offline mode expands the user retention and engagement by giving the user a chance to remain on your web pages for a longer period of time.
