    Progressive Web App [PWA] for vBulletin

    Progressive Web App for vBulletin


    Overview:


    Progressive Web App (PWA) is a collection of latest technologies for web and mobile apps.


    A Progressive Web App is:
    • Progressive - Works for every user, regardless of browser choice because it's built with progressive enhancement as a core tenet.
    • Responsive - Fits any form factor: desktop, mobile, tablet, or whatever is next.
    • Connectivity independent - Enhanced with service workers to work offline or on low-quality networks.
    • App-like - Feels like an app, because the app shell model separates the application functionality from application content .
    • Fresh - Always up-to-date thanks to the service worker update process.
    • Safe - Served via HTTPS to prevent snooping and to ensure content hasn't been tampered with.
    • Discoverable - Is identifiable as an "application" thanks to W3C manifest and service worker registration scope, allowing search engines to find it.
    • Re-engageable - Makes re-engagement easy through features like push notifications.
    • Installable - Allows users to add apps they find most useful to their home screen without the hassle of an app store.
    • Linkable - Easily share the application via URL, does not require complex installation.




    This product allows you to design a PWA for your forum using a simple service worker for offline webpage. For best experience, use this in combination with Web Push notifications. Read more about PWA here: https://developers.google.com/web/progressive-web-apps/






    Pre-requisites:


    To fully benefit from PWA, your forum must fulfill the following:

    1. HTTPS enabled
    2. Responsive style






    Optional



    1. Install Web Push Notifications, https://vbulletin.org/forum/showthread.php?t=326558
    2. Upload your forum logo images with at least two sizes, 512x512 and 128x128 pixel




    With PWA and web push, you no longer need an app on Play store.




    To Install:



    1. Upload the files from upload folder of attached zip to your forum root directory
    2. Modify manifest.json file as per your forum requirement and upload it to your forum root directory.
      If you are using the Web Push Notifications product, you may already have manifest.json file on your server. Simply modify that file and fill the missing tags
    3. Install the product using the xml file in AdminCP -> Plugins & Products -> Manage Products -> Add/Import Product.


    Click Installed. Keep your mobile users engaged.

    The only file that you have to edit is the manifest.json file.


    Code:
    {
    	"name" : "vB 4 Mobile",
    	"short_name" : "vB4Mobile",
    	"scope" : "/",
    	"display" : "standalone",
    	"start_url" : "/",
    	"theme_color" : "#7192a8",
    	"description" : "vBulletin 4 Mobile, Responsive and PWA",
    	"orientation" : "any",
    	"background_color" : "#7192a8",
    	"icons": [
    		{
    		  "src": "/images/vBlogo.png",
    		  "type": "image/png",
    		  "sizes": "512x512"
    		}
    	]
    }

    All fields are self-explanatory. name, short_name, description, theme_color, background_color. For the icon, upload at least one square image of size 512x512 and update "src" field by replacing "/images/vBlogo.png" with the path to your own logo image.


    For information on how to write manifest.json, visit https://developers.google.com/web/fu...-app-manifest/


    If you are using Web Push notifications add-on, then you will also have "gcm_sender_id" field at the end.

    PWA works differently on iOS.


    According to https://medium.com/@firt/progressive...e-d00430dee3a7 , you will have to look for the Add to Home Screen button in share options.




    What PWAs can do on Android and not on iOS

    • On Android you can store more than 50 Mb
    • Android doesn’t delete the files if you don’t use the app, but it can delete the files under storage pressure. Also, if installed or used a lot by the user the PWA can request Persistent Storage
    • Bluetooth access for BLE devices
    • Web Share for accessing native share dialog
    • Speech Recognition
    • Background Sync and Web Push Notifications
    • Web App Banner to invite the user to install the app
    • You can customize (a little bit) the splash screen and the orientations you want
    • With WebAPK and Chrome, users can’t install more than one instance of a PWA
    • With WebAPK and Chrome, the PWAs appears under Settings and you can see data usage; on iOS everything appears under Safari
    • With WebAPK and Chrome, the PWA manages intents for its URL, so if you get a link to the PWA, it will be opened in standalone mode and not within the browser’s window.




    What PWAs can do on iOS and not on Android

    • Users can change icon’s name before installing it
    • They can be configured in a configuration profile, so corporate users can receive PWAs shortcuts from the company (that’s a good one!). Safari uses the term WebClip for this feature; however it doesn’t seem to be reading the Web App Manifest (according to the documentation)
