Can you change Generate to Generates please?

I'm still learning about PWAs but I wasn't aware that there was a dependency there on Google Workbox. Is that just an implementation detail of your plugin?

@mattr- It's an implementation by Google to make it easier to get started.

Thanks guys. As DirtyF says, Google Workbox has already developed a series of tools . If you use Webpack or Gulp as your build tool, you can easily generate a service worker with these tools. But in my blog, I don't want to use even npm, and I want to precache recent 10 posts so that they are offline available to visitors even though these posts were never opened by visitors before. That's why I try to integrate this function in Jekyll build process.

In the service worker generated by this plugin, I still use Workbox API such as precache and runtime cache routes inside. But through the relative configuration in _config.yml, I think it will help a lot for those who are not familiar with Workbox.

Cool plugin, will check it out. 🚀

@xiaoiver You might want to update the plugin's usage section. When i initially tried adding the gem and config block to my test site, bundle exec jekyll serve failed with an error..
(resumed properly after I manually copied the contents of your vendor/ to my site)

Note: This should ideally be a bug report in your repo, but the plugin is only at 0.0.1 .. bound to have issues..

Hi @ashmaroli , in this plugin I want to copy two files(a polyfill & workbox) under /vendor to _site/js:

Dir.glob(File.expand_path('../vendor/**/*', __FILE__)) do |filepath_to_copy|
    basename = File.basename(filepath_to_copy)
    FileUtils.copy_file(filepath_to_copy, File.join(@site.dest, 'js', basename))

So in service worker generated, I can import these scripts correctly:
importScripts('#{@site.baseurl}/js/#{vendor_file}');

Maybe I make a wrong assumption that users put their scripts in /js.
Since I'm not very familiar with Ruby and Jekyll indeed, plz point it out if I make some mistakes.
