Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

~~Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.~~

Why we dropped Lerna from PouchDB

We dropped Lerna from our monorepo architecture in PouchDB 6.0.0. I got a question about this from @reconbot, so I thought I'd explain our reasoning.

First off, I don't want this post to be read as "Lerna sucks, don't use Lerna." We started out using Lerna, but eventually outgrew it because we wrote our own custom thing. Lerna is still a great idea if you're getting started with monorepos (monorepi?).

	// UPDATE: In 2023, you should probably stop using this! The narrow version of Safari that
	// does not support `nomodule` is probably not being used anywhere. The code below is left
	// for posterity.

	/**
	* Safari 10.1 supports modules, but does not support the `nomodule` attribute - it will
	* load <script nomodule> anyway. This snippet solve this problem, but only for script
	* tags that load external code, e.g.: <script nomodule src="nomodule.js"></script>
	*
	* Again: this will not prevent inline script, e.g.:

	_registry = {};
	importPolyfill = path => {
	if(!(path in _registry)) {
	const entry = _registry[path] = {};
	entry.promise = new Promise(resolve => entry.resolve = resolve);
	document.head.appendChild(Object.assign(
	document.createElement('script'),
	{
	type: 'module',
	innerText: `import * as X from '${path}'; _registry['${path}'].resolve(X);`,
