# Parcel plugin for sw-caching

A [Parcel](https://parceljs.org/) plugin to run [workbox-build](https://github.com/GoogleChrome/workbox) after every build.

```sh
yarn add -D parcel-plugin-sw-cache
# or
npm install -D parcel-plugin-sw-cache
```

The plugin is configured using the `cache` object inside `package.json` of your project. ([Example](example/package.json)).
Configuration keys used by the plugin (default options first):
```js
{
"dependencies": {
// ...
},
//...
"cache": {
"disablePlugin": false || true,
"inDev": false || true,
"strategy": "default" || "inject"
"clearDist": true || false
}
//...
}
```

The remaining properties in this object will be passed to `generateSW` or `injectManifest` (depending on `strategy`). See https://developers.google.com/web/tools/workbox/reference-docs/latest/module-workbox-build

In `inject` mode, occurences of `__PUBLIC` will be replaced with Parcel's public-url option. In this case, `swSrc` is also a required parameter.

No configuration options are mandatory, the default configuration will work just fine. (Creating a service worker to precache all files in the output directory without runtime caching). With `strategy: "default"`, the default parameters passed to workbox-build are (which precaching all html, js, css, jpg and png files):
```js
{
globDirectory: outDir,
globPatterns: ["**/*.{html,js,css,jpg,png}"],
swDest: swDest,
navigateFallback: publicURL + "/index.html",
clientsClaim: true,
skipWaiting: true,
templatedURLs: {
"/": ["index.html"]
}
}
```
and with `inject`:
```js
{
globDirectory: outDir,
globPatterns: [
"**/*.{html,js,css,jpg,png,gif,svg,eot,ttf,woff,woff2}"
],
swDest: swDest,
templatedURLs: {
"/": ["index.html"]
}
}
```

To specify a RegExp, use an array instead (`ignoreURLParametersMatching`, `navigateFallbackWhitelist`, `runtimeCaching.urlPattern`, `injectionPointRegexp`).
```js
runtimeCaching: [
{
urlPattern: /my-match\/api\.[0-9]+/i
}
]
```
becomes
```json
"runtimeCaching": [
{
"urlPattern": ["my-match\/api\\.[0-9]+", "i"]
}
]
```
