How to setup Let's Encrypt for Nginx on Ubuntu 16.04 (including IPv6, HTTP/2 and A+ SLL rating)

There are two main modes to run the Let's Encrypt client (called Certbot):

Standalone: replaces the webserver to respond to ACME challenges
Webroot: needs your webserver to serve challenges from a known folder.

Webroot is better because it doesn't need to replace Nginx (to bind to port 80).

In the following, we're setting up mydomain.com. HTML is served from /var/www/mydomain, and challenges are served from /var/www/letsencrypt.

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

var Article = require('../../../models/article');

Those suck for maintenance and they're ugly.

Possible solutions

This is an example of how to scaffold API endpoints to list / get / create / update / delete Posts in a Keystone website.

It's a modification of the default project created with the yo keystone generator (see https://github.com/JedWatson/generator-keystone)

Gists don't let you specify full paths, so in the project structure the files would be:

routes-index.js        -->    /routes/index.js         // modified to add the api endpoints
routes-api-posts.js    -->    /routes/api/posts.js     // new file containing the Post API route controllers

	export async function tryGetRevertReason(to: string, from: string, data: string): Promise<string \| undefined> {
	const provider = ethers.getDefaultProvider();
	const tx = { to, from, data };
	try {
	await provider.estimateGas(tx);
	} catch {
	const value = await provider.call(tx);
	return hexDataLength(value) % 32 === 4 && hexDataSlice(value, 0, 4) === '0x08c379a0'
	? defaultAbiCoder.decode(['string'], hexDataSlice(value, 4))
	: undefined;
