Progressive Web App for vBulletin


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/


To fully benefit from PWA, your forum must fulfill the following:
  1. HTTPS enabled
  2. Responsive style

  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.

Block Disabled:      (Update License Status)  
Suspended or Unlicensed Members Cannot View Code.

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.

If I understood correctly, this product will make my site Responsive? If so, I will apply it and see the changes. obviously always make a backup

iA1 04 Nov 2018 14:49

No, this does not make your site responsive. You will need a responsive style for that.

This is Progressive Web App, which makes your site similar to a mobile app in certain ways.

I installed it on vB4.2.5 (PHP7.0) and... no effect.
Using my iPhone with Safari and Chrome, it still shows the same mobile Style from vB, no change to see.

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.

If you are able to find it, please post some screenshots for other users. I don't have an iPhone to test it out.

What PWAs can do on Android and not on iOS
  • On Android you can store more than 50 Mb
  • Android doesnít delete the files if you donít 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 canít 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 browserís window.

What PWAs can do on iOS and not on Android
  • Users can change iconís name before installing it
  • They can be configured in a configuration profile, so corporate users can receive PWAs shortcuts from the company (thatís a good one!). Safari uses the term WebClip for this feature; however it doesnít seem to be reading the Web App Manifest (according to the documentation)

So, if I understand this right, I need to have your responsive style, which you offer as a paid service in order for this modification?

It doesn't have to be my responsive style. Any responsive style will do. Even the mobile style that you get bundled with vB 4 will work fine.

Making a responsive style requires time and effort. As far as I know, there is no freely available responsive style for vB 3 and vB 4 at the moment.

I get that completely - I wanted to be sure that the requirements was something that did not require it to be something that you had specifically done. I'll test this out on my site over the next week

Hopefully it's not to late or expensive ;)

CharlieDelta 26 Nov 2018 15:08

Interesting. Will check this out.

Is it an Android phone? I can see it on my android phone.

This products enables PWA for your site, but displaying the Add to Home Screen banner is browser dependent. Each browser decides how and when to display the banner or not to display it at all. We don't have any control over it. We only enable all the features required to display it.

See the icon on lower-right corner, beside the camera

Works on all Android devices. iOS is not yet supported.

scottkoz20 19 Oct 2019 16:46
