This app illustrates how to use Passport with Express to sign users in with an Ethereum wallet. 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/passport/todos-express-ethereum.git
$ cd todos-express-ethereum
$ npm installThen start the server.
$ npm startNavigate to http://localhost:3000.
This app illustrates how to build a todo app with sign in functionality using
Express, Passport, and the passport-ethereum-siwe
strategy.
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 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 Ethereum Provider API is used to request that the user sign a message. 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.
