# Jekyll Workbox Plugin [](http://badge.fury.io/rb/jekyll-workbox-plugin)
> Google Workbox integration for Jekyll
This plugin provides integration with [Google Workbox](https://developers.google.com/web/tools/workbox/) for the [Jekyll](https://jekyllrb.com/) static site generator. It generates a service worker and provides precache integration with artifacts managed by Jekyll.
This plugin provides [workbox-cli](https://developers.google.com/web/tools/workbox/modules/workbox-cli) like functionality for projects using Jekyll. It's based on the [Jekyll PWA Plugin](https://github.com/lavas-project/jekyll-pwa), but it tries to be less clever than that, and focuses purely on the Workbox integration.
You see this plugin in action on [my website](https://benediktmeurer.de), which is built using Jekyll and comes with a service worker for offline capabilities.
## Installation
This plugin is available as a [RubyGem][ruby-gem].
### Option #1
Add `gem 'jekyll-workbox-plugin'` to the `jekyll_plugin` group in your `Gemfile`:
```ruby
source 'https://rubygems.org'
gem 'jekyll'
group :jekyll_plugins do
gem 'jekyll-workbox-plugin'
end
```
Then run `bundle` to install the gem.
### Option #2
Alternatively, you can also manually install the gem using the following command:
```
$ gem install jekyll-workbox-plugin
```
After the plugin has been installed successfully, add the following lines to your `_config.yml` in order to tell Jekyll to use the plugin:
```yaml
plugins:
- jekyll-workbox-plugin
```
## Getting Started
### Configuration
Add the following configuration block to Jekyll's `_config.yml`:
```yaml
workbox:
sw_src_filepath: sw.js # Optional
sw_dest_filename: sw.js # Optional
precache_recent_posts_num: 5 # Optional
precache_glob_directory: / # Optional
precache_glob_patterns: # Optional
- "{js,css,fonts}/**/*.{js,css,eot,svg,ttf,woff}"
- index.html
- "about.html": # This entry aliases about/ and contact/ to about.html
- about/
- contact/
precache_glob_ignores: # Optional
- "fonts/**/*"
```
Parameter | Description
---------- | ------------
sw_src_filepath | Filepath of the source service worker. Defaults to `sw.js`
sw_dest_filename | Filename of the destination service worker. Defaults to `sw.js`
precache_glob_directory | Directory of precache. [Workbox Config](https://developers.google.com/web/tools/workbox/get-started/webpack#optional-config)
precache_glob_patterns | Patterns of precache. Accepts aliased names pointing to the same file to support pretty permalinks. [Workbox Config](https://developers.google.com/web/tools/workbox/get-started/webpack#optional-config)
precache_glob_ignores | Ignores of precache. [Workbox Config](https://developers.google.com/web/tools/workbox/get-started/webpack#optional-config)
precache_recent_posts_num | Number of recent posts to precache.
### Write your own Service Worker
Create a file `sw.js` in the root path of your Jekyll project. You can change this source file's path with `sw_src_filepath` option if you don't like the default.
Now you can write your own Service Worker with [Workbox APIs](https://developers.google.com/web/tools/workbox/reference-docs/latest/), including a line `workbox.precaching.precacheAndRoute([]);`, which will be re-written by this plugin according to the precache configuration specified in the `_config.yml` file.
Here's what the `sw.js` like in my site.
```javascript
// sw.js
// set names for both precache & runtime cache
workbox.core.setCacheNameDetails({
prefix: 'benediktmeurer.de',
suffix: 'v1',
precache: 'precache',
runtime: 'runtime-cache'
});
// let Service Worker take control of pages ASAP
workbox.skipWaiting();
workbox.clientsClaim();
// default to `networkFirst` strategy
workbox.routing.setDefaultHandler(workbox.strategies.networkFirst());
// let Workbox handle our precache list
// NOTE: This will be populated by jekyll-workbox-plugin.
workbox.precaching.precacheAndRoute([]);
// use `Stale-while-revalidate` strategy for images and fonts.
workbox.routing.registerRoute(
/images/,
workbox.strategies.staleWhileRevalidate()
);
workbox.routing.registerRoute(
/^https?:\/\/fonts\.googleapis\.com/,
workbox.strategies.staleWhileRevalidate()
);
```
Make sure to follow the [Service Worker Checklist](https://developers.google.com/web/tools/workbox/guides/service-worker-checklist) from the Workbox documentation. Insert this snippet in your JavaScript code somewhere:
```js
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('/sw.js');
});
}
```
i.e. put it inline near the closing `
