Wen Connect? Now!

Wen is under active development, thigns can change quickly

Minimalistic library for Web3 user interfaces.

• Seamless connection flows to Metamask.
• Stateless sessions that work anywhere (client, serverless, Edge Functions).
• Respectful of user privacy. Take only the needed information, nothing more. Never saved to a DB.

Usage

yarn add wen-connect
or
npm install wen-connect --save

Wen works in all JavaScript applications, but offers different bindings for different frameworks.

React

One single context: WenProvider, and one hook: useWen for everything.

Add WenProvider to your root component:

import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
import { WenProvider } from "wen-connect";
ReactDOM.render(   <React.StrictMode>     <WenProvider>       <App />     </WenProvider>   </React.StrictMode>,   document.getElementById("root") );

Use the hook to engage with your user:

import { useWen } from "wen-connect";
const MyComponent = () => {   const { connect, disconnect, wallet } = useWen();
const handleConnect = () => {     // Optional argument to specify which chain to get the user connected on.     connect({ chainId: "0xa86a" });   };
const handleDisconnect = () => {     disconnect();   };
return <span>{wallet.address}</span>; };

wallet contains the following info:

address: string
balance: Hex string
chainId: Hex string
connected: boolean
connector: "injected"

Next.js

Wen also works server-side with Next.js to let you connect. Activate the ssr prop in the provider and add your provider to app.tsx:

import { WenProvider } from "wen-connect";
function MyApp({ Component, pageProps }) {   const config = { ssr: true };   return (     <WenProvider config={config}>       <Component {...pageProps} />     </WenProvider>   ); }

Create a pages/api/wen.ts for Wen to use JWT sessions:

export { WenConnect as default } from "wen-connect";

Add a WEN_SECRET environment variable in your .env file. It will be used to encrypt the JWT token.

Now, you can get the session in getServerSideprops and use it to hydrate Wen on the client-side first render.

import { getSession, useWen } from "wen-connect";
function Index(props) {   // Passing the session will avoid empty initial renders, saving your users loading time.   const { wallet } = useWen(props.session);
return <div>{wallet.address}</div>; }
export default Index;
export const getServerSideProps = async (context) => {   return {     props: {       // session.wallet is the same info as const { wallet } = useWen(props session);       session: getSession(context),     },   }; };

Roadmap:

• Signing in desired user state.
• Svelte and SvelteKit bindings.
• Wallet connect.
• Coinbase wallet.
• The graph integrations.
• More examples.
