Example express app using passport.js to authenticate with OAuth2.0
This app illustrates how to use Passport.js with Express to sign users in with Keyp. Use this example as a starting point for your own web applications.
To run this app, clone the repository and install dependencies:
$ git clone https://github.com/UseKeyp/usekeyp-example-app-express.git
$ yarn This app requires OAuth 2.0 credentials from Keyp, which can be obtained by
setting up
a client in Keyp's Developer Portal.
The redirect URI of the OAuth client should be set to http://localhost:3000/redirect/keyp.
Once credentials have been obtained, create a .env file and add the following
environment variables:
KEYP_CLIENT_ID=INSERT_CLIENT_ID_HEREStart the server.
$ yarn startNavigate to http://localhost:3000.
This app illustrates how to build a todo app with sign in functionality using
Express, Passport, and Keyp
This app is a traditional web application, in which application logic and data persistence resides on the server. HTML pages and forms are rendered by the server and client-side JavaScript is not utilized (or kept to a minimum).
This app is built using the Express web framework. Data is persisted to a SQLite database. HTML pages are rendered using EJS templates, and are styled using vanilla CSS.
When a user first arrives at this app, they are prompted to sign in. To sign in, the user is redirected to Keyp using OpenID Connect. Once authenticated, a login session is established and maintained between the server and the user's browser with a cookie.
After signing in, the user can view, create, and edit todo items. Interaction occurs by clicking links and submitting forms, which trigger HTTP requests. The browser automatically includes the cookie set during login with each of these requests.
When the server receives a request, it authenticates the cookie and restores the login session, thus authenticating the user. It then accesses or stores records in the database associated with the authenticated user.

Original Google OAuth & Express demo app was created by Jared Hanson and adapted by Keyp to use Keyp's OAuth process.
