## ✨ Features

- **Easy Integration:** Quickly add wallet connection functionality to your dApp.
- **Customizable:** Tailor the look and feel to match your application's design.
- **Responsive:** Optimized for different screen sizes and devices.

## 🛠 Prerequisites

Before using NFID IdentityKit, ensure that you have:

- An ICP project with a frontend canister.

## 📦 Installation

A library to integrate compatible ICP wallets into your application, which contains React-specific
components for integrating compatible ICP wallets into your application.

Install library with the following command:

```sh npm2yarn
npm install @nfid/identitykit
```

### 🔗 Peer Dependencies

IdentityKit requires certain peer dependencies to function correctly. Ensure the following packages
are installed in your project:

```sh npm2yarn
npm install @dfinity/ledger-icp @dfinity/identity @dfinity/agent @dfinity/candid @dfinity/principal @dfinity/utils @dfinity/auth-client
```

**Note:** IdentityKit is a React library and exports styles that need to be imported into your
project.

## 🚀 Usage

### 🎨 Import Styles

Begin by importing the necessary styles in your project:

```javascript
import "@nfid/identitykit/react/styles.css"
```

### 🧩 Wrap Your Application with `IdentityKitProvider`

Next, wrap your entire application with the `IdentityKitProvider` to enable wallet connections:

```javascript
import { IdentityKitProvider } from "@nfid/identitykit/react"

const App = () => {
  return (
    <IdentityKitProvider>
      <YourApp />
    </IdentityKitProvider>
  )
}
```

### 🔗 Add the Connect Button

Finally, import and render the `ConnectWallet` component in your application to allow users to
connect their wallets:

```javascript
import { ConnectWallet } from "@nfid/identitykit/react"

export const YourApp = () => {
  return <ConnectWallet />
}
```

Once integrated, IdentityKit will handle your user's wallet selection, display wallet information,
and manage wallet switching.

## 🔬 Playground

IdentityKit comes with its own playground where you can try things out locally.

There are two applications included:

1. `Demo` (react-demo) - This app is for application developers. It's a simple frontend app with
   IdentityKit integrated. It runs on port 3002 and lets you sign in with IdentityKit and make
   canister calls. Check it out at https://qzjsg-qiaaa-aaaam-acupa-cai.icp0.io/demo
2. `Signer` (react-signer) - This is a sample signer app that demonstrates the basics of signer
   functionality. It helps to understand what’s happening on the signer side. It runs on port 3003.

To get the playground up and running, use the following command:

```sh
npm i && npm run playground
```
