NEAR dApp

Decision Router

Determine which path to follow:

Path A: New Project

User wants to create a new NEAR dApp from scratch.

1. Read references/create-near-app.md
2. Run scaffolding:

npx create-near-app@latest

Or with arguments:

npx create-near-app my-app --frontend vite-react --contract rs --install

Framework options: vite-react | next-app | next-page Contract options: rs (Rust) | ts (TypeScript)

1. If user needs wallet connection in the scaffolded app, also follow Path B.

Path B: Existing Project

User wants to add NEAR wallet connection to an existing React app.

1. Read references/near-connect-hooks.md — React hooks API and patterns
2. If user needs low-level wallet API or non-React integration, also read references/near-connect.md

Quick setup:

npm install near-connect-hooks @hot-labs/near-connect near-api-js

// 1. Wrap app root with NearProvider
import { NearProvider } from 'near-connect-hooks';
<NearProvider config={{ network: 'mainnet' }}>
  <App />
</NearProvider>
// 2. Use hook in components
import { useNearWallet } from 'near-connect-hooks';
const { signedAccountId, signIn, signOut, viewFunction, callFunction } = useNearWallet();

Path C: Non-React or Vanilla JS

Use @hot-labs/near-connect directly without React hooks.

1. Read references/near-connect.md

npm install @hot-labs/near-connect

import { NearConnector } from "@hot-labs/near-connect";
const connector = new NearConnector({ network: "mainnet" });
connector.on("wallet:signIn", async (t) => {
  const wallet = await connector.wallet();
  const address = t.accounts[0].accountId;
});
await connector.connect();

Key Patterns

• Read contract state (no wallet): viewFunction({ contractId, method, args })
• Write to contract (wallet required): callFunction({ contractId, method, args, deposit })
• Transfer NEAR: transfer({ receiverId, amount })
• NEAR ↔ yoctoNEAR: Use nearToYocto() / yoctoToNear() from near-api-js
• 1 NEAR = "1000000000000000000000000" yoctoNEAR
• Default gas: "30000000000000" (30 TGas)
