encryptly-cli

CLI for generating apps for encryptly.net authentication service

Installing and updating the CLI (server side)

npm i encryptly-cli@latest -g

Encryptly SDK

This package is used on server, and provides functionality for verifying the received token after your users' successful login

https://www.npmjs.com/package/encryptly-auth-sdk

Encryptly Client

This package is used in the client, and provides functionality for connecting to Encryptly Authentication Service in order to log in the user.

https://www.npmjs.com/package/encryptly-client

Usage

encryptly-cli generate:app 
    --server-url "https://auth.encryptly.net" 
    --name "My App"
    --redirect-url "https://example.com/api/auth/oauth/login"
    --url "https://example.com"

Options

Option	Alias	Description	Required
-s	--server-url	Authentication server url to use	Yes
-n	--name	Your app's name	Yes
-r	--redirect-url	URL that users will be redirected to after successful login	Yes
-u	--url	URL of your app	Yes

CLI App Generation Result

You will most likely copy these values into an .env file on your server, as such:

ENCRYPTLY_CLIENT_ID=0b3bde10-f5cf-47a1-bd64-ed9103217c86
ENCRYPTLY_CLIENT_SECRET=76bd6936-5430-4deb-a3da-a8b099f0aa61
ENCRYPTLY_SERVER_URL=http://localhost:5001

What to do after successful login

There are two ways your users will be redirected to authentication server:

1. Popup
2. Page redirect

METHOD 1: Popup

Your client should open a window using javascript.

// STEP 1: Create popup (client side)
import { createPopup } from "encryptly-client";

const serverUrl = "https://auth.encryptly.net";
const clientId = "<YOUR GENERATED CLIENT ID>";
const type = "login"; // or "register"
createPopup({serverUrl, clientId, type}, token => handleEncryptlyResponse(token))

// You will need to create "handleEncryptlyResponse" function
// or whatever you want to call it
// Next step involves verifying the token from "createPopup" response

// STEP 2: Verify token (server side)
// Example: NodeJS express auth controller

const { checkToken } = require("encryptly-auth-sdk");

exports.oauthLogin = async (req, res) => {
    // If you passed the token using ?token=<TOKEN>
    if (!req.query.token) {
        return res.status(400).send({ error: "No token provided" });
    }

    const serverUrl = process.env.ENCRYPTLY_SERVER_URL;
    const clientId = process.env.ENCRYPTLY_CLIENT_ID;
    const clientSecret = process.env.ENCRYPTLY_CLIENT_SECRET;

    const response = await checkToken({
        token: req.query.token,
        serverUrl,
        clientId,
        clientSecret
    });

    // In case of wrong token
    if (response.error) {
        return res.sendStatus(401);
    }

    // User object received from authentication server
    const { _id, displayName, email, firstName, lastName } = response.user;

    // Handle retrieving or adding the user to your own database
    // Or whatever you wish to do with the user object
    let user = await User.findOne({ email: email });
    if (!user) {
        user = new User({
            displayName,
            email,
            oauthId: _id,
            accessLevel: "User",
        });
        await user.save();
    }

    const jwtUserData = {
        userId: user._id,
        userAccessLevel: user.accessLevel,
    };
    const jwtToken = jwt.sign(jwtUserData, process.env.JWT_SECRET);

    res.send({ token: jwtToken });
}

METHOD 2: Page Redirect

After a successful login, users will be redirected to the specified redirect URL. This can be useful when the user is visiting your app on mobile

// STEP 1: Redirect user to authentication server (client side)
import { redirectToAuthServer } from "encryptly-client";

const serverUrl = "https://auth.encryptly.net";
const clientId = "<YOUR GENERATED CLIENT ID>";
const type = "login"; // or "register"
// NOTE: the following "redirectUrl" is NOT the
// --redirect-url option from the CLI.
// It is most likely the current page that your
// user is visiting, or any other page on the client
// that you want your users to be redirected to
// after successful login
const redirectUrl = "<URL THAT YOUR USERS WILL BE REDIRECTED TO>"
redirectToAuthServer({serverUrl, clientId, type, redirectUrl})

// The only difference from the popup method
// is that here you specify "redirectUrl"

// STEP 2: Verify token after successful login (server side)
// This can be done using the same controller method as
// in STEP 2 for popup method, except that you
// will need to redirect to your frontend

// Example (oauth login controller method)
// ...

const jwtUserData = {
    userId: user._id,
    userAccessLevel: user.accessLevel,
};
const jwtToken = jwt.sign(jwtUserData, process.env.JWT_SECRET);
let redirectUrl = req.query.redirectUrl ? req.query.redirectUrl : "/";
redirectUrl = redirectUrl + "?token=" + jwtToken;

return res.redirect(redirectUrl);
