# letsencrypt-hapi
|
|
|
|
Free SSL and Automatic HTTPS for node.js with hapi.js and other middleware systems via Let's Encrypt
|
|
|
|
* Automatic Registration via SNI (`httpsOptions.SNICallback`)
|
|
* **registrations** require an **approval callback** in *production*
|
|
* Automatic Renewal (around 80 days)
|
|
* **renewals** are *fully automatic* and happen in the *background*, with **no downtime**
|
|
* Automatic vhost / virtual hosting
|
|
|
|
All you have to do is start the webserver and then visit it at it's domain name.
|
|
|
|
## Install
|
|
|
|
```
|
|
npm install --save letsencrypt-express@2.x
|
|
```
|
|
|
|
*Pay no attention to the man behind the curtain.* (just ignore that the name of the module is letsencrypt-express)
|
|
|
|
### Part 1: Configure LetsEncrypt
|
|
|
|
```javascript
|
|
'use strict';
|
|
|
|
var le = require('letsencrypt-express').create({
|
|
server: 'staging' // in production use https://acme-v01.api.letsencrypt.org/directory
|
|
|
|
, configDir: require('os').homedir() + '/letsencrypt/etc'
|
|
|
|
, approveDomains: function (opts, certs, cb) {
|
|
opts.domains = certs && certs.altnames || opts.domains;
|
|
opts.email = 'john.doe@example.com' // CHANGE ME
|
|
opts.agreeTos = true;
|
|
|
|
cb(null, { options: opts, certs: certs });
|
|
}
|
|
|
|
, debug: true
|
|
});
|
|
```
|
|
|
|
WARNING: If you don't do any checks and simply complete `approveDomains` callback,
|
|
an attacker will spoof SNI packets with bad hostnames and that will cause you to be rate-limited
|
|
and/or blocked from the ACME server.
|
|
Alternatively, You can run registration *manually*:
|
|
|
|
```bash
|
|
npm install -g letsencrypt-cli
|
|
|
|
letsencrypt certonly --standalone \
|
|
--server 'https://acme-v01.api.letsencrypt.org/directory' \
|
|
--config-dir ~/letsencrypt/etc \
|
|
--agree-tos --domains example.com --email user@example.com
|
|
|
|
# Note: the '--webrootPath' option is also available if you don't want to shut down your webserver to get the cert.
|
|
```
|
|
|
|
### Part 2: Just add Hapi
|
|
|
|
```javascript
|
|
var hapi = require('hapi');
|
|
var https = require('spdy');
|
|
var server = new hapi.Server();
|
|
var acmeResponder = le.middleware();
|
|
var httpsServer = https.createServer(le.httpsOptions).listen(443);
|
|
|
|
server.connection({ listener: httpsServer, autoListen: false, tls: true });
|
|
|
|
server.route({
|
|
method: 'GET'
|
|
, path: '/.well-known/acme-challenge'
|
|
, handler: function (request, reply) {
|
|
var req = request.raw.req;
|
|
var res = request.raw.res;
|
|
|
|
reply.close(false);
|
|
acmeResponder(req, res);
|
|
}
|
|
});
|
|
|
|
server.route({
|
|
method: 'GET'
|
|
, path: '/'
|
|
, handler: function (request, reply) {
|
|
reply("Hello, I'm so Hapi!");
|
|
}
|
|
});
|
|
```
|
|
|
|
### Part 3: Redirect http to https
|
|
|
|
```javascript
|
|
var http = require('http');
|
|
var redirectHttps = require('redirect-https')();
|
|
|
|
http.createServer(le.middleware(redirectHttps)).listen(80, function () {
|
|
console.log('handle ACME http-01 challenge and redirect to https');
|
|
});
|
|
```
