SSH private keys are just normal PEM files, so you can use Eckles or Rasha, as mentioned above.

You can install ssh-to-jwk and use it from command line:

npm install -g ssh-to-jwk

ssh-to-jwk ~/.ssh/id_rsa.pub

You can also use it from JavaScript:

var fs = require('fs');
var sshtojwk = require('sshtojwk');

var pub = fs.readFileSync("./id_rsa.pub");
var jwk = sshtojwk(pub);

console.info(jwk);
