Create SSL server using express (nodejs)

expressSSL

### GENERATE PRIVATE KEY (key.pem)
# openssl req -newkey rsa:2048 -new -nodes -keyout key.pem -out csr.pem 

### GENERATE CERTIFICATE (cert.pem)
# openssl req -newkey rsa:2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem

express = require("express")
fs = require('fs')
https = require('https')

app = new express()
app.use(express.logger())
app.get("/", (req, res)-> res.send("ssl mode!"))
options = {
  key: fs.readFileSync('key.pem')
  cert: fs.readFileSync('cert.pem')
}
https.createServer(options, app).listen(443)
