PwaManifestGenerator

A Rails engine and gem for generating and managing PWA (Progressive Web App) manifests with advanced configuration, validation, and Rails generator support.

Features

• Strongly-typed manifest builder with validation
• Rails generator to install and override pwa/manifest.json.erb
• Supports all modern PWA manifest fields, including advanced keys (shortcuts, screenshots, edge_side_panel, etc.)
• Extensible and testable Ruby code

Installation

Add this line to your application's Gemfile:

gem 'pwa_manifest_generator', github: 'Dandush03/pwa_manifest_generator'

And then execute:

bundle install

Usage

Rails Setup

Run the install generator to copy the manifest template:

bin/rails generate pwa_manifest_generator:install

This will override app/views/pwa/manifest.json.erb with a template that uses your Rails config.

Configuration Example

In an initializer (e.g. config/initializers/pwa.rb):

PwaManifestGenerator::Builder.config do |pwa|
  pwa.name = 'My App'
  pwa.short_name = 'App'
  pwa.start_url = '/'
  # ...set other keys as needed
end

Manifest Template

The generated manifest.json.erb will use your configuration and output a valid PWA manifest.

Development

After checking out the repo, run bin/setup to install dependencies. Run tests with:

rake test
