What is a PWA
Progressive Web App
A PWA is a website developed in such a way as to be recognized by the browser as an App and therefore installed on the device.
Independence
A site developed as a PWA will not depend on any App Store and navigation of the site will also be available offline, because at the time of installation the site already resides entirely on the device.
Why develop a PWA
User Experience
If the site is developed as a PWA it will be available by clicking the icon on the device screen. Consequently it will behave like an App and you will have more space on the display as you will not use the browser to navigate.
Performance
The website developed as a PWA is installed on the device, but a website is very light compared to normal apps and will therefore weigh very little on the device's memory. In this way the loading of pages is very fast.
Memory storage
There will not be continuous updates that increase the size of the PWA while decreasing the available space on the user's device.
