In case someone wishes to programmatically create CSRs from node.js, there is a Node.js module available. This module, which can be found on GitHub, utilizes openssl to generate a private key and a CSR.
Note: It is recommended to use the pem module instead, as it is more comprehensive and likely more reliable.
Alternatively, there is the option to explore forge, which offers a pure JavaScript implementation for creating CSRs.

To generate a certificate using the shell, you can use the following commands:
openssl genrsa -out server-key.pem 1024
openssl req -new -key server-key.pem -out server-csr.pem
openssl x509 -req -in server-csr.pem -signkey server-key.pem -out server-cert.pem
Once you have generated the certificate files, you can use them in your Node.js application:
var https = require('https');
https.createServer({
key: fs.readFileSync('server-key.pem'),
cert: fs.readFileSync('server-cert.pem')
},
function (req, res) {
// Your server logic here
})
EDIT:
You can also try using the “openssl-wrapper” package from NPM to generate the certificate directly within your Node.js application. Here’s an example:
var openssl = require('openssl-wrapper');
var password = 'github';
return openssl.exec('genrsa', {des3: true, passout: 'pass:' + password, '2048': false}, function(err, buffer) {
console.log(buffer.toString());
});
Please note that I haven’t personally tested this package, so I can’t guarantee its functionality. But it seems like a possible solution for generating certificates using Node.js.

node-forge allows for the usage of X.509 certificates without relying on the OpenSSL shell command. This eliminates the need for external dependencies.
You can find more information about node-forge and its X.509 capabilities on the official GitHub page.
