Node.js : How to get a basic HTTPS web server up and running!
Once you have node.js installed on your system, you can just follow the procedure below to get a basic web server running with support for both HTTP and HTTPS!
Step 1 : Build a Certificate Authority
1.1. create the folder where you want to store your key & certificate :
mkdir conf
1.2. go to that directory :
cd conf
1.3. grab this ca.cnf file to use as a configuration shortcut :
wget https://raw.githubusercontent.com/anders94/https-authorized-clients/master/keys/ca.cnf
1.4. create a new certificate authority using this configuration :
openssl req -new -x509 -days 9999 -config ca.cnf -keyout ca-key.pem -out ca-cert.pem
1.5. now that we have our certificate authority in ca-key.pem and ca-cert.pem, let's generate a private key for the server :
openssl genrsa -out key.pem 4096
1.6. grab this server.cnf file to use as a configuration shortcut:
wget https://raw.githubusercontent.com/anders94/https-authorized-clients/master/keys/server.cnf
1.7. generate the certificate signing request using this configuration :
openssl req -new -config server.cnf -key key.pem -out csr.pem
1.8. sign the request :
openssl x509 -req -extfile server.cnf -days 999 -passin "pass:password" -in csr.pem -CA cacert.pem -CAkey ca-key.pem -CAcreateserial -out cert.pem
Step 2 : Install your certificate as a root certificate
2.1. copy your certificate to your root certificates' folder :
sudo cp ca-crt.pem /usr/local/share/ca-certificates/ca-crt.pem
2.2. update CA store :
sudo update-ca-certificates
Step 3 : Starting your node server
First, you want to create a server.js file that contains your actual server code. The minimal setup for an HTTPS server in Node.js would be something like this :
var https = require('https');var fs = require('fs');var httpsOptions = { key: fs.readFileSync('path/to/server-key.pem'), cert: fs.readFileSync('path/to/server-crt.pem')};var app = function (req, res) { res.writeHead(200); res.end("hello world
");}https.createServer(httpsOptions, app).listen(4433);
If you also want to support http requests, you need to make just this small modification :
var http = require('http');var https = require('https');var fs = require('fs');var httpsOptions = { key: fs.readFileSync('path/to/server-key.pem'), cert: fs.readFileSync('path/to/server-crt.pem')};var app = function (req, res) { res.writeHead(200); res.end("hello world
");}http.createServer(app).listen(8888);https.createServer(httpsOptions, app).listen(4433);
3.1. go to the directory where your server.js is located :
cd /path/to
3.2. run server.js :
node server.js
With all that being said, I highly recommend you keep learning!
