## Getting started

Eexample is built atop of [NextJS](https://nextjs.org/) in order to abstract complexity of setting up bundlers, routing etc. So there are few steps you need to follow in order to set everything up

1. Go to [WalletConnect Cloud](https://cloud.walletconnect.com/sign-in) and obtain a project id

2. Add your project details in [WalletConnectUtil.ts](https://github.com/WalletConnect/web-examples/blob/main/wallets/react-wallet-v2/src/utils/WalletConnectUtil.ts) file

3. Install dependencies `yarn install` or `npm install`

4. Setup your environment variables

```bash
cp .env.local.example .env.local
```

Your `.env.local` now contains the following environment variables:

- `NEXT_PUBLIC_PROJECT_ID` (placeholder) - You can generate your own ProjectId at https://cloud.walletconnect.com
- `NEXT_PUBLIC_RELAY_URL` (already set)

5. Run `yarn dev` or `npm run dev` to start local development

## Navigating through example

1. Initial setup and initializations happen in [_app.ts](https://github.com/WalletConnect/web-examples/blob/main/wallets/react-wallet-v2/src/pages/_app.tsx) file
2. WalletConnect client, ethers and cosmos wallets are initialized in [useInitialization.ts ](https://github.com/WalletConnect/web-examples/blob/main/wallets/react-wallet-v2/src/hooks/useInitialization.ts) hook
3. Subscription and handling of WalletConnect events happens in [useWalletConnectEventsManager.ts](https://github.com/WalletConnect/web-examples/blob/main/wallets/react-wallet-v2/src/hooks/useWalletConnectEventsManager.ts) hook, that oppens related [Modal views](https://github.com/WalletConnect/web-examples/tree/main/wallets/react-wallet-v2/src/views) and passes them all necesary data
4. [Modal views](https://github.com/WalletConnect/web-examples/tree/main/wallets/react-wallet-v2/src/views) are responsible for data display and handling approval or rejection actions
5. Uppon approval or rejection modals pass request data to [RequestHandlerUtil.ts](https://github.com/WalletConnect/web-examples/blob/main/wallets/react-wallet-v2/src/utils/RequestHandlerUtil.ts) that performs all necesary work based on request method and returns formated json rpc result data that can be then used for WallteConnect client responses
