A Blink contains the complete, interactive data structure. It includes all necessary information to display and interact with a Blink, including its current state, possible actions, and related data.

Web

This section covers adding Blinks directly to your React dApp using our Blinks React SDK. The SDK is open-source and can be found on our Github.

​
Installation

npm install @dialectlabs/blinks

​
Adding Component

To simplify the integration, the following hooks are exported from @dialectlabs/blinks/react

  • useBlink - This is the overall hook, it fetches the BlinkInstance, initializes a security registry, and refreshes it every 10 minutes.
  • useBlinksRegistryInterval - This fetches the security registry and refreshes it.
  • useBlinkSolanaWalletAdapter - This sets up an adapter for Blink using a wallet provider.

If you want to build your own hooks, use Blink , BlinksRegistry , and BlinkConfig/BlinkAdapter classes and interfaces.

If you are using the useBlinkSolanaWalletAdapter hook, then be sure to have<WalletProvider />and<WalletModalProvider /> above in the component tree.

​
Usage

Here’s a basic setup:

/**
 * Important: This component must be wrapped with <WalletProvider />
 * and <WalletModalProvider /> in your application.
 */

import "@dialectlabs/blinks/index.css";

import {
  Blink,
  useBlink,
  useBlinksRegistryInterval,
} from "@dialectlabs/blinks";
import { useBlinkSolanaWalletAdapter } from "@dialectlabs/blinks/hooks/solana";

const App = () => {
  // URL of your endpoint (blink provider)
  const blinkApiUrl = "...";

  // Initiates adapter
  const { adapter } = useBlinkSolanaWalletAdapter(
    "<YOUR_RPC_URL_OR_CONNECTION>"
  );

  // Fetches the blink from the provided URL
  const { blink, isLoading } = useBlink({ url: blinkApiUrl });

  if (isLoading) return null;

  return <Blink blink={blink} adapter={adapter} />;
};

The URLs in blinkApiUrl must be direct Blink provider URLs and not interstitials or website urls with actions.json

​
Mobile

This section covers adding blinks directly to your React Native dApp through our React Native SDK for Blinks. The SDK is completely open-source and can be found on our GitHub.

​
Installation

npm install @dialectlabs/blinks @dialectlabs/blinks-react-native

​
Adding Component

The following imports are needed to simplify the Blink integration:

  • useBlink hook and BlinkAdapter type from @dialectlabs/blinks
  • Blink component from @dialectlabs/blinks-react-native

​
Usage

A getWalletAdapter function has to be defined to generate an BlinkAdapter for interactions with user wallets, like wallet connect and signing transactions through the React Native dApp.

After that, the <Blink /> component can be used in the React Native dApp to render the Blink. It takes the following props:

  • theme - has the styling for the blink to be rendered;
  • blink - object returned from useBlink function (which requires the adapter from getWalletAdapter and Blink Provider URL);
  • websiteUrl - the complete URL of the Blink;
  • websiteText - the domain name of the Blink URL;
import { useBlink, type BlinkAdapter } from "@dialectlabs/blinks";
import { Blink } from "@dialectlabs/blinks-react-native";
import { PublicKey } from "@solana/web3.js";
import type React from "react";

function getWalletAdapter(): BlinkAdapter {
  return {
    connect: async (_context) => {
      console.log("connect");
      return PublicKey.default.toString();
    },
    signTransaction: async (_tx, _context) => {
      console.log("signTransaction");
      return {
        signature: "signature",
      };
    },
    confirmTransaction: async (_signature, _context) => {
      console.log("confirmTransaction");
    },
  };
}

export const BlinkInTheWalletIntegrationExample: React.FC<{
  url: string; // could be blink api or website url
}> = ({ url }) => {
  const adapter = getWalletAdapter();
  const { blink } = useBlink({ url });

  if (!blink) {
    // return placeholder component
  }
  const blinkUrl = new URL(url);
  return (
    <Blink
      theme={{
        "--blink-button": "#1D9BF0",
        "--blink-border-radius-rounded-button": 9999,
        // and any other custom styles
      }}
      blink={blink}
      adapter={adapter}
      websiteUrl={blinkUrl.href}
      websiteText={blinkUrl.hostname}
    />
  );
};
