Single Sign-On (SSO) support for Eve Online

This module provides a simple interface to Eve Online's Single Sign-On oAuth process. Requested access tokens can then be used to authenticate an Eve character or to access the RESTful CREST API.


npm install eve-singlesignon --save

Set up

In order to use Single Sign-On feature, you first need to create a new application in the developer section.

This will give you the required client ID and secret. You will need to give the redirect (or callback) URL, the URL where the client will be redirected to after logging in (this is the /sso_callback in the example below).


Example with Express

This is an incomplete and minimalistic example of how to use the most basic functionality. Refer to the source code for further inline documentation.

import { default as express } from 'express';
import { SingleSignOn } from 'eve-singlesignon';
const app = express();
// Here you can provide the required parameters 
const CLIENT_ID = 'client_id';
const SECRET_KEY = 'secret_key';
const CALLBACK_URL = '';
// Create a new instance with the set parameters 
const sso = new SingleSignOn(CLIENT_ID, SECRET_KEY, CALLBACK_URL);
// Refer the client to the Eve Online SSO login screen on login 
app.get('/login', function(req, res) {
    return res.redirect(sso.getRedirectUrl());
// This is the callback that is called when the client has logged in 
app.get('/sso_callback', function(req, res) {
    // Get an access token for this authorization code 
    sso.getAccessToken(req.query.code).then(result => {
        // The result contains the access token and expiry time 
        console.log('Access Token:', result.access_token);
        console.log('Expires in:', result.expires_in);
        // Store the access token so you can use it later 
        // Access basic character info 
        return sso.verifyAccessToken(result.access_token);
    .then(result => {
        // We now have some basic info... 
        console.log('Character ID:', result.CharacterID);
        console.log('Character Name:', result.CharacterName);
    .catch(err => {
        // An error occurred 
// Start the server 
app.listen(3000, () => {
    console.log('Server running on port 3000');
