Generate a Application Cache Manifest to support offline access.
I have developed this for the intention of using it exclusively for single page applications.
While it can be extended to support App Cache Manifests for multiple pages, I have no intent at this point in time to develop support for this.
If it is something that you do need, please let me know and I'll investigate how it could work without compromising the configuration syntax.
Add the following line to Gemfile, then run bundle install:
gem 'middleman-appcache'Add a link to the appcache name in you html layout:
<html manifest="manifest.appcache">
...
</html>And active the extension inside config.rb:
activate :app_cache do |config|
config.cache_manifest = 'manifest.appcache'
config.cache = %w(index.html favicon.ico stylesheets/*.css javascripts/*.js images/*)
endThen when you run middleman build, the application cache will be generated in the build directory.
The extension has 5 optionally configurable fields:
activate :app_cache do |config|
config.cache_manifest = 'manifest.appcache'
config.cache = %w(index.html offline.html favicon.ico stylesheets/*.css javascripts/*.js images/*)
config.network = %w(/ /login /logout)
config.fallback = {
'/' => 'offline.html'
}
config.use_relative = false
config.version_hash = true
endThe above configuration will generate the following appcache:
