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`: ```bash 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 ``` 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 ``` 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). - DNS Validation - [**Wildcards**](https://git.rootprojects.org/root/greenlock-express.js/src/branch/master/examples/wildcards/README.md) - [**Localhost**](https://git.rootprojects.org/root/greenlock-express.js/src/branch/master/examples/localhost/README.md) - [**CI/CD**](https://git.rootprojects.org/root/greenlock-express.js/src/branch/master/examples/ci-cd/README.md) # Full Documentation Most of the documentation is done by use-case examples, as shown up at the top of the README.
