# [Greenlock Express](https://git.rootprojects.org/root/greenlock-express.js) is Let's Encrypt for Node
![Greenlock Logo](https://git.rootprojects.org/root/greenlock.js/raw/branch/master/logo/greenlock-1063x250.png "Greenlock Logo")
| Built by [Root](https://therootcompany.com) for [Hub](https://rootprojects.org/hub/)
Free SSL, Automated HTTPS / HTTP2, served with Node via Express, Koa, hapi, etc.
### Let's Encrypt for Node, Express, etc
```js
require("greenlock-express")
.init(function getConfig() {
return { package: require("./package.json") };
})
.serve(httpsWorker);
function httpsWorker(server) {
// Works with any Node app (Express, etc)
var app = require("./my-express-app.js");
// See, all normal stuff here
app.get("/hello", function(req, res) {
res.end("Hello, Encrypted World!");
});
// Serves on 80 and 443
// Get's SSL certificates magically!
server.serveApp(app);
}
```
Manage via API or the config file:
```json
{
"subscriberEmail": "letsencrypt-test@therootcompany.com",
"agreeToTerms": true,
"sites": {
"example.com": {
"subject": "example.com",
"altnames": ["example.com", "www.example.com"]

# 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
mkdir ~/my-project
pushd ~/my-project
npm init
```
## 2. Create an http app (i.e. express)
This example is shown with Express, but any node app will doGreenlock
works with everything.
(or any node-style http app)
`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);
// export the app normally
// do not .listen()
module.exports = app;
```
## 3. Serve with Greenlock Express
Greenlock Express is designed with these goals in mind:
- Simplicity and ease-of-use
- Performance and scalability
- Configurability and control
You can start with **near-zero configuration** and
slowly add options for greater performance and customization
later, if you need them.
`server.js`:
```js
require("greenlock-express")
.init(getConfig)
.serve(worker);
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")
};
}
function worker(server) {
// Works with any Node app (Express, etc)
var app = require("my-express-app.js");
server.serveApp(app);
}
```
And start your server:
```bash
# Allow non-root node to use ports 80 (HTTP) and 443 (HTTPS)
sudo setcap 'cap_net_bind_service=+ep' $(which node)
```
```bash
# `npm start` will call `node ./server.js` by default
npm start
```
```txt
Greenlock v3.0.0
Greenlock Manager Config File: ~/.config/greenlock/manager.json
Greenlock Storage Directory: ~/.config/greenlock/
Listening on 0.0.0.0:80 for ACME challenges and HTTPS redirects
Listening on 0.0.0.0:443 for secure traffic
```
## 4. Manage domains
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**:
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:
```bash
# Set a global subscriber account
npx greenlock config --subscriber-email 'mycompany@example.com' --agree-to-terms true
```
<!-- todo print where the key was saved -->
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).
```bash
# Add a certificate with specific domains
npx greenlock add --subject example.com --altnames example.com,www.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).

- [**Wildcards**](https://git.rootprojects.org/root/greenlock-express.js/src/branch/master/examples/wildcards/README.md)
