# [Greenlock Express](https://git.rootprojects.org/root/greenlock-express.js) is Let's Encrypt for Node

| 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 and Express (and Koa, hapi, rill, etc)
Greenlock Express is a **Web Server** with **Fully Automated HTTPS** and renewals.
You define your app, and let Greenlock handle issuing and renewing Free SSL Certificates.
**Cloud-ready** with Node `cluster`.
# Serve your Sites with Free SSL
-   1. Create a Project with Greenlock Express
-   2. Initialize and Setup
-   3. Add Domains, and Hello, World!
### Create your project
```bash
npm init
```
```bash
npm install --save greenlock-express@v3
```
```bash
npx greenlock init --maintainer-email 'jon@example.com' --manager-config-file ./greenlock.json
```
server.js
```js
"use strict";
require("greenlock-express")
    .init(function() {
        return {
            greenlock: require("./greenlock.js"),
            // whether or not to run at cloudscale
            cluster: false
        };
    })
    .ready(function(glx) {
        var app = require("./app.js");
        // Serves on 80 and 443
        // Get's SSL certificates magically!
        glx.serveApp(app);
    });
```
 
greenlock.js
```js
"use strict";
var pkg = require("./package.json");
module.exports = require("@root/greenlock").create({
    // name & version for ACME client user agent
    packageAgent: pkg.name + "/" + pkg.version,
    // contact for security and critical bug notices
    maintainerEmail: pkg.author,
    // where to find .greenlockrc and set default paths
    packageRoot: __dirname
});
```
 
`app.js`:
```js
var app = function(req, res) {
    res.end("Hello, Encrypted World!");
};
module.exports = app;
```
```bash
npx greenlock defaults --subscriber-email 'jon@example.com' --agree-to-terms
```
```bash
npx greenlock add --subject example.com --altnames example.com
```
```bash
npm start -- --staging
```

# QuickStart Guide
Easy as 1, 2, 3... 4
1. Create a node project
## 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)
## 2. Create an http app (i.e. express)
This example is shown with Express, but any node app will do. Greenlock
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
## 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 SSL Certificates and Domains
## 4. Manage domains
The management API is built to work with Databases, S3, etc.
HOWEVER, by default it starts with a simple config file.
`~/.config/greenlock/manager.json`:
```json
{
    "subscriberEmail": "letsencrypt-test@therootcompany.com",
    "agreeToTerms": true,
    "sites": {
        "example.com": {
            "subject": "example.com",
            "altnames": ["example.com", "www.example.com"]
        }
    }
}
```
COMING SOON
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
# COMING SOON
# (this command should be here by Nov 5th)
# (edit the config by hand for now)
#
# Set a global subscriber account
npx greenlock config --subscriber-email 'mycompany@example.com' --agree-to-terms true
```
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
# COMING SOON
# (this command should be here by Nov 5th)
# (edit the config by hand for now)
#
# Add a certificate with specific domains
npx greenlock add --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).
