# QuickStart Guide
 | 
			
		||||
 | 
			
		||||
Easy as 1, 2, 3... 4
 | 
			
		||||
 | 
			
		||||
## 1. Create a node project
 | 
			
		||||
 | 
			
		||||
Create an empty node project.
 | 
			
		||||
 | 
			
		||||
Be sure to fill out the package name, version, and an author email.
 | 
			
		||||
 | 
			
		||||
```bash
 | 
			
		||||
npm install --save greenlock-express@2.x
 | 
			
		||||
mkdir ~/my-project
 | 
			
		||||
pushd ~/my-project
 | 
			
		||||
npm init
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
# QuickStart
 | 
			
		||||
## 2. Create an http app (i.e. express)
 | 
			
		||||
 | 
			
		||||
<!-- TODO better quickstart (fewer options) -->
 | 
			
		||||
This example is shown with Express, but any node app will doGreenlock
 | 
			
		||||
works with everything.
 | 
			
		||||
(or any node-style http app)

		||||

		||||
 | 
			
		||||
### Working Example Code
 | 
			
		||||
 | 
			
		||||
Here's a completely working example that will get you started.
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
git clone https://git.rootprojects.org/root/greenlock-express.js.git
 | 
			
		||||
pushd greenlock-express.js
 | 
			
		||||
  npm install
 | 
			
		||||
popd
 | 
			
		||||
 | 
			
		||||
# edit 'email' and 'approveDomains' in
 | 
			
		||||
# greenlock-express.js/examples/simple.js
 | 
			
		||||
 | 
			
		||||
node greenlock-express.js/examples/simple.js
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
All you have to do is start the webserver and then visit it at its domain name.
 | 
			
		||||
 | 
			
		||||
`server.js`:
 | 
			
		||||
 | 
			
		||||
```javascript
 | 
			
		||||
"use strict";
 | 
			
		||||
 | 
			
		||||
require("greenlock-express")
 | 
			
		||||
	.create({
 | 
			
		||||
		email: "john.doe@example.com", // The email address of the ACME user / hosting provider
 | 
			
		||||
		agreeTos: true, // You must accept the ToS as the host which handles the certs
 | 
			
		||||
		configDir: "~/.config/acme/", // Writable directory where certs will be saved
 | 
			
		||||
		communityMember: true, // Join the community to get notified of important updates
 | 
			
		||||
		telemetry: true, // Contribute telemetry data to the project
 | 
			
		||||
 | 
			
		||||
		// Using your express app:
 | 
			
		||||
		// simply export it as-is, then include it here
 | 
			
		||||
		app: require("./app.js")
 | 
			
		||||
 | 
			
		||||
		//, debug: true
 | 
			
		||||
	})
 | 
			
		||||
	.listen(80, 443);
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
`app.js`:
 | 
			
		||||
`my-express-app.js`:
 | 
			
		||||
 | 
			
		||||
```js
 | 
			
		||||
"use strict";
 | 
			
		||||
 | 
			
		||||
// A plain, node-style app
 | 
			
		||||
 | 
			
		||||
function myPlainNodeHttpApp(req, res) {
 | 
			
		||||
	res.end("Hello, Encrypted World!");
 | 
			
		||||
}
 | 
			
		||||
 | 
			
		||||
// Wrap that plain app in express,
 | 
			
		||||
// because that's what you're used to
 | 
			
		||||
 | 
			
		||||
var express = require("express");
 | 
			
		||||
var app = express();
 | 
			
		||||
app.get("/", myPlainNodeHttpApp);
 | 
			
		||||
 | 
			
		||||
app.use("/", function(req, res) {
 | 
			
		||||
	res.setHeader("Content-Type", "text/html; charset=utf-8");
 | 
			
		||||
	res.end("Hello, World!\n\n💚 🔒.js");
 | 
			
		||||
});
 | 
			
		||||
// export the app normally
 | 
			
		||||
// do not .listen()
 | 
			
		||||
 | 
			
		||||
// Don't do this:
 | 
			
		||||
// app.listen(3000)
 | 
			
		||||
 | 
			
		||||
// Do this instead:
 | 
			
		||||
module.exports = app;
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
### `communityMember`
 | 
			
		||||
## 3. Serve with Greenlock Express
 | 
			
		||||
 | 
			
		||||
If you're the kind of person that likes the kinds of stuff that I do,
 | 
			
		||||
well, I want to do more of it and I'd like to get you involved.
 | 
			
		||||
Greenlock Express is designed with these goals in mind:
 | 
			
		||||
 | 
			
		||||
As expected, by default we keep your email private and only use it for
 | 
			
		||||
transactional messaging, urgent security or API updates
 | 
			
		||||
(such as the mandatory upgrade to Let's Encrypt v2), and ACME account registration.
 | 
			
		||||
- Simplicity and ease-of-use
 | 
			
		||||
- Performance and scalability
 | 
			
		||||
- Configurability and control
 | 
			
		||||
 | 
			
		||||
However, when you set the `communityMember` option to `true` we'll also
 | 
			
		||||
inform you when there are meaningful and relavant feature updates (no bugfix noise),
 | 
			
		||||
and give you early access to similar projects.
 | 
			
		||||
You can start with **near-zero configuration** and
 | 
			
		||||
slowly add options for greater performance and customization
 | 
			
		||||
later, if you need them.
 | 
			
		||||
 | 
			
		||||
You can see our full privacy policy at <https://greenlock.domains/legal/#privacy>.
 | 
			
		||||
`server.js`:
 | 
			
		||||
 | 
			
		||||
### What if the example didn't work?
 | 
			
		||||
```bash
 | 
			
		||||
require("greenlock-express")
 | 
			
		||||
	.init(getConfig)
 | 
			
		||||
	.serve(worker);
 | 
			
		||||
 | 
			
		||||
Double check the following:
 | 
			
		||||
function getConfig() {
 | 
			
		||||
	return {
 | 
			
		||||
		// uses name and version as part of the ACME client user-agent
 | 
			
		||||
    // uses author as the contact for support notices
 | 
			
		||||
		package: require("./package.json")
 | 
			
		||||
	};
 | 
			
		||||
}
 | 
			
		||||
 | 
			
		||||
- **Public Facing IP** for `http-01` challenges
 | 
			
		||||
  - Are you running this _as_ a public-facing webserver (good)? or localhost (bad)?
 | 
			
		||||
  - Does `ifconfig` show a public address (good)? or a private one - 10.x, 192.168.x, etc (bad)?
 | 
			
		||||
  - If you're on a non-public server, are you using the `dns-01` challenge?
 | 
			
		||||
- **correct ACME version**
 | 
			
		||||
  - Let's Encrypt **v2** (ACME v2) must use `version: 'draft-11'`
 | 
			
		||||
  - Let's Encrypt v1 must use `version: 'v01'`
 | 
			
		||||
- **valid email**
 | 
			
		||||
  - You MUST set `email` to a **valid address**
 | 
			
		||||
  - MX records must validate (`dig MX example.com` for `'john@example.com'`)
 | 
			
		||||
- **valid DNS records**
 | 
			
		||||
  - Must have public DNS records (test with `dig +trace A example.com; dig +trace www.example.com` for `[ 'example.com', 'www.example.com' ]`)
 | 
			
		||||
- **write access**
 | 
			
		||||
  - You MUST set `configDir` to a writeable location (test with `touch ~/acme/etc/tmp.tmp`)
 | 
			
		||||
- **port binding privileges**
 | 
			
		||||
  - You MUST be able to bind to ports 80 and 443
 | 
			
		||||
  - You can do this via `sudo` or [`setcap`](https://gist.github.com/firstdoit/6389682)
 | 
			
		||||
- **API limits**
 | 
			
		||||
  - You MUST NOT exceed the API [**usage limits**](https://letsencrypt.org/docs/staging-environment/) per domain, certificate, IP address, etc
 | 
			
		||||
- **Red Lock, Untrusted**
 | 
			
		||||
  - You MUST use the **production** server url, not staging
 | 
			
		||||
  - The API URL should not have 'acme-staging-v02', but should have 'acme-v02'
 | 
			
		||||
  - Delete the `configDir` used for getting certificates in staging
 | 
			
		||||
 | 
			
		||||
### Production vs Staging
 | 
			
		||||
 | 
			
		||||
If at first you don't succeed, stop and switch to staging.
 | 
			
		||||
 | 
			
		||||
There are a number of common problems related to system configuration -

firewalls, ports, permissions, etc - that you are likely to run up against
 | 
			
		||||
when using greenlock for your first time.
 | 
			
		||||
 | 
			
		||||
I've put a "dry run" in place with built-in diagnostics, so hopefully
 | 
			
		||||
you get everything right on your first or second try.
 | 
			
		||||
 | 
			
		||||
However, in order to avoid being blocked by hitting the bad request rate limits
 | 
			
		||||
you should switch to using the `staging` server for any testing or debugging.

# Usage
 | 
			
		||||
 | 
			
		||||
The oversimplified example was the bait
 | 
			
		||||
(because everyone seems to want an example that fits in 3 lines, even if it's terribly bad practices),
 | 
			
		||||
now here's the switch.
 | 
			
		||||
 | 
			
		||||
We have another completely working example that will provides a little more to build off of.
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
git clone https://git.rootprojects.org/root/greenlock-express.js.git
 | 
			
		||||
pushd greenlock-express.js
 | 
			
		||||
  npm install
 | 
			
		||||
popd
 | 
			
		||||
 | 
			
		||||
# replace 'fooCheckDb' in
 | 
			
		||||
# greenlock-express.js/examples/normal.js
 | 
			
		||||
 | 
			
		||||
node greenlock-express.js/examples/normal.js
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
It looks a little more like this:
 | 
			
		||||
 | 
			
		||||
`serve.js`:
 | 
			
		||||
 | 
			
		||||
```javascript
 | 
			
		||||
"use strict";
 | 
			
		||||
 | 
			
		||||
// returns an instance of greenlock.js with additional helper methods
 | 
			
		||||
var glx = require("greenlock-express").create({
 | 
			
		||||
	server: "https://acme-v02.api.letsencrypt.org/directory",
 | 
			
		||||
	// Note: If at first you don't succeed, stop and switch to staging:
 | 
			
		||||
	// https://acme-staging-v02.api.letsencrypt.org/directory
 | 
			
		||||
	version: "draft-11", // Let's Encrypt v2 (ACME v2)
 | 
			
		||||
 | 
			
		||||
	// If you wish to replace the default account and domain key storage plugin
 | 
			
		||||
	store: require("le-store-certbot").create({
 | 
			
		||||
		configDir: require("path").join(require("os").homedir(), "acme", "etc"),
 | 
			
		||||
		webrootPath: "/tmp/acme-challenges"
 | 
			
		||||
	}),
 | 
			
		||||
 | 
			
		||||
	// Contribute telemetry data to the project
 | 
			
		||||
	telemetry: true,
 | 
			
		||||
 | 
			
		||||
	// the default servername to use when the client doesn't specify
 | 
			
		||||
	// (because some IoT devices don't support servername indication)
 | 
			
		||||
	servername: "example.com",
 | 
			
		||||
 | 
			
		||||
	approveDomains: approveDomains
 | 
			
		||||
});
 | 
			
		||||
 | 
			
		||||
var server = glx.listen(80, 443, function() {
 | 
			
		||||
	console.log("Listening on port 80 for ACME challenges and 443 for express app.");
 | 
			
		||||
});
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Note: You shouldn't be using the plain HTTP server for anything except, potentially, for error handling
 | 
			
		||||
on the listen event (if the default print-and-quit behavior doesn't work for your use case).
 | 
			
		||||
If you need to do that, here's how:
 | 
			
		||||
 | 
			
		||||
```
 | 
			
		||||
var plainServer = server.unencrypted;
 | 
			
		||||
plainServer.on('error', function (err) { ... });
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
The Automatic Certificate Issuance is initiated via SNI (`httpsOptions.SNICallback`).
 | 
			
		||||
For security, domain validation MUST have an approval callback in _production_.
 | 
			
		||||
 | 
			
		||||
```javascript
 | 
			
		||||
var http01 = require("le-challenge-fs").create({ webrootPath: "/tmp/acme-challenges" });
 | 
			
		||||
function approveDomains(opts, certs, cb) {
 | 
			
		||||
	// This is where you check your database and associated
 | 
			
		||||
	// email addresses with domains and agreements and such
 | 
			
		||||
	// if (!isAllowed(opts.domains)) { return cb(new Error("not allowed")); }
 | 
			
		||||
 | 
			
		||||
	// The domains being approved for the first time are listed in opts.domains
 | 
			
		||||
	// Certs being renewed are listed in certs.altnames (if that's useful)
 | 
			
		||||
 | 
			
		||||
	// Opt-in to submit stats and get important updates
 | 
			
		||||
	opts.communityMember = true;
 | 
			
		||||
 | 
			
		||||
	// If you wish to replace the default challenge plugin, you may do so here
 | 
			
		||||
	opts.challenges = { "http-01": http01 };
 | 
			
		||||
 | 
			
		||||
	opts.email = "john.doe@example.com";
 | 
			
		||||
	opts.agreeTos = true;
 | 
			
		||||
 | 
			
		||||
	// NOTE: you can also change other options such as `challengeType` and `challenge`
 | 
			
		||||
	// opts.challengeType = 'http-01';
 | 
			
		||||
	// opts.challenge = require('le-challenge-fs').create({});
 | 
			
		||||
 | 
			
		||||
	cb(null, { options: opts, certs: certs });
 | 
			
		||||
function worker(server) {
 | 
			
		||||
	// Works with any Node app (Express, etc)
 | 
			
		||||
  var app = require('my-express-app.js');
 | 
			
		||||
	server.serveApp(app);
 | 
			
		||||
}
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
```javascript
 | 
			
		||||
// handles acme-challenge and redirects to https
 | 
			
		||||
require("http")
 | 
			
		||||
	.createServer(glx.middleware(require("redirect-https")()))
 | 
			
		||||
	.listen(80, function() {
 | 
			
		||||
		console.log("Listening for ACME http-01 challenges on", this.address());
 | 
			
		||||
	});
 | 
			
		||||
And start your server:
 | 
			
		||||
 | 
			
		||||
var app = require("express")();
 | 
			
		||||
app.use("/", function(req, res) {
 | 
			
		||||
	res.end("Hello, World!");
 | 
			
		||||
});
 | 
			
		||||
 | 
			
		||||
// handles your app
 | 
			
		||||
require("https")
 | 
			
		||||
	.createServer(glx.httpsOptions, app)
 | 
			
		||||
	.listen(443, function() {
 | 
			
		||||
		console.log("Listening for ACME tls-sni-01 challenges and serve app on", this.address());
 | 
			
		||||
	});
 | 
			
		||||
```bash
 | 
			
		||||
# Allow non-root node to use ports 80 (HTTP) and 443 (HTTPS)
 | 
			
		||||
sudo setcap 'cap_net_bind_service=+ep' $(which node)
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
**Security**:
 | 
			
		||||
```bash
 | 
			
		||||
# `npm start` will call `node ./server.js` by default
 | 
			
		||||
npm start
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Greenlock will do a self-check on all domain registrations
 | 
			
		||||
to prevent you from hitting rate limits.
 | 
			
		||||

# API

Listening on 0.0.0.0:80 for ACME challenges and HTTPS redirects
 |

```
 | 
			
		||||
 | 
			
		||||
This module is an elaborate ruse (to provide an oversimplified example and to nab some SEO).
 | 
			
		||||
## 4. Manage domains
 | 
			
		||||
 | 
			
		||||
The API is actually located at [greenlock.js options](https://git.rootprojects.org/root/greenlock.js)
 | 
			
		||||
(because all options are simply passed through to `greenlock.js` proper without modification).
 | 
			
		||||
Management can be done via the **CLI** or the JavaScript [**API**](https://git.rootprojects.org/root/greenlock.js/).
 | 
			
		||||
Since this is the QuickStart, we'll demo the **CLI**:
 | 
			
		||||
 | 
			
		||||
The only "API" consists of two options, the rest is just a wrapper around `greenlock.js` to take LOC from 15 to 5:
 | 
			
		||||
You need to create a Let's Encrypt _subscriber account_, which can be done globally, or per-site.
 | 
			
		||||
All individuals, and most businesses, should set this globally:
 | 
			
		||||
 | 
			
		||||
- `opts.app` An express app in the format `function (req, res) { ... }` (no `next`).
 | 
			
		||||
- `server = glx.listen(plainAddr, tlsAddr, onListen)` Accepts port numbers (or arrays of port numbers) to listen on, returns secure server.
 | 
			
		||||
  - `listen(80, 443)`
 | 
			
		||||
  - `listen(80, 443, onListenSecure)`
 | 
			
		||||
  - `listen(80, 443, onListenPlain, onListenSecure)`
 | 
			
		||||
  - `listen('localhost:80', '0.0.0.0:443')`
 | 
			
		||||
  - `listen('[::1]:80', '[::]:443')`
 | 
			
		||||
  - `listen('/tmp/glx.plain.sock', '/tmp/glx.secure.sock')`
 | 
			
		||||
```bash
 | 
			
		||||
# Set a global subscriber account
 | 
			
		||||
npx greenlock config --subscriber-email 'mycompany@example.com' --agree-to-terms true
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Brief overview of some simple options for `greenlock.js`:
 | 
			
		||||
<!-- todo print where the key was saved -->
 | 
			
		||||
 | 
			
		||||
- `opts.server` set to https://acme-v02.api.letsencrypt.org/directory in production
 | 
			
		||||
- `opts.version` set to `v01` for Let's Encrypt v1 or `draft-11` for Let's Encrypt v2 (mistakenly called ACME v2)
 | 
			
		||||
- `opts.email` The default email to use to accept agreements.
 | 
			
		||||
- `opts.agreeTos` When set to `true`, this always accepts the LetsEncrypt TOS. When a string it checks the agreement url first.
 | 
			
		||||
- `opts.communityMember` Join the community to get notified of important updates and help make greenlock better
 | 
			
		||||
- `opts.approveDomains` can be either of:
 | 
			
		||||
  - An explicit array of allowed domains such as `[ 'example.com', 'www.example.com' ]`
 | 
			
		||||
  - A callback `function (opts, certs, cb) { cb(null, { options: opts, certs: certs }); }` for setting `email`, `agreeTos`, `domains`, etc (as shown in usage example above)
 | 
			
		||||
- `opts.renewWithin` is the **maximum** number of days (in ms) before expiration to renew a certificate.
 | 
			
		||||
- `opts.renewBy` is the **minimum** number of days (in ms) before expiration to renew a certificate.
 | 
			
		||||
A Let's Encrypt SSL certificate has a "Subject" (Primary Domain) and up to 100 "Alternative Names"
 | 
			
		||||
(of which the first _must_ be the subject).
 | 
			
		||||
 | 
			
		||||
## Supported ACME versions
 | 
			
		||||
```bash
 | 
			
		||||
# Add a certificate with specific domains
 | 
			
		||||
npx greenlock add --subject example.com --altnames example.com,www.example.com
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
- Let's Encrypt v1 (aka v01)
 | 
			
		||||
- Let's Encrypt v2 (aka v02 or ACME draft 11)
 | 
			
		||||
- ACME draft 11 (ACME v2 is a misnomer)
 | 
			
		||||
- Wildcard domains (via dns-01 challenges)
 | 
			
		||||
  - `*.example.com`
 | 
			
		||||
<!-- todo print where the cert was saved -->

 | 
			
		||||
This will update the config file (assuming the default fs-based management plugin):
 | 
			
		||||
 | 
			
		||||
`~/.config/greenlock/manager.json`:
 | 
			
		||||
 | 
			
		||||
```json
 | 
			
		||||
{
 | 
			
		||||
	"subscriberEmail": "letsencrypt-test@therootcompany.com",
 | 
			
		||||
	"agreeToTerms": true,
 | 
			
		||||
	"sites": {
 | 
			
		||||
		"example.com": {
 | 
			
		||||
			"subject": "example.com",
 | 
			
		||||
			"altnames": ["example.com", "www.example.com"]
 | 
			
		||||
		}
 | 
			
		||||
	}
 | 
			
		||||
}
 | 
			
		||||
```
 | 
			
		||||
 | 
			
		||||
Note: **Localhost**, **Wildcard**, and Certificates for Private Networks require
 | 
			
		||||
[**DNS validation**](https://git.rootprojects.org/root/greenlock-exp).
