<±/> diffHTML ServiceWorker Middleware

Stable Version: 1.0.0-beta.9

while this does not really benefit from being a middleware, i made it as such since it looks nice when added to use() and can be disabled if the middleware is unsubscribed. i've added some developer niceties, like auto clearing the caches for development. it's also possible to disable the worker completely if you get annoyed with some behavior.

Installation

npm install diffhtml-middleware-service-worker

Example

import { use } from 'diffhtml';
import serviceWorker from 'diffhtml-middleware-service-worker';

// Defaults shown, these are all optional values.
use(serviceWorker({
  url: '/service-worker.js',
  scope: '/',
  autoClearCaches: location.search.includes('diff_autoclear'),
  disable: location.search.includes('diff_disable'),
  quiet: location.search.includes('diff_quiet'),
  options: {},
}));

Options

These options are available to change depending on the use case. It is entirely possible to get away with simply:

use(serviceWorker());

If you meet the the default use case.

url

Specifies which Service Worker URL to load.

scope

Specifices the path to use, called scope since it restricts what content is visible.

autoClearCaches

Allow the middleware to automatically clear all caches. By default this is disabled as it defeats the point of a service worker and may muck with other apps running on localhost. Can be toggled via the query param ?diff_autoclear.

disable

Unregisters all Service Workers and does not try to register a new one. This can be toggled via the query param: ?diff_disable.

quiet

Do not log anything to the console. Can be toggled via the query param ?diffhtml_quiet.

options

Defaults to an empty object, gets spread into the Service Worker registration call.

You can’t perform that action at this time.
