@dialectlabs/blinks-react-native

React Native SDK for rendering blinks for Solana Actions on mobile dApps. Check out our documentation for more information on what actions and blinks are and how to build them.

Installation

# npm
npm i @dialectlabs/blinks-react-native

#yarn
yarn add @dialectlabs/blinks-react-native

Adding the Blink Component

The following imports need to be made to simplify the blink integration:

• useAction hook and ActionAdapter type from @dialectlabs/blinks-react-native
• Blink component from @dialectlabs/blinks-react-native

A getWalletAdapter function has to be defined to generate an adapter of type ActionAdapter 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
• action - object returned by the useAction function (which requires the adapter from getWalletAdapter and Action URL)
• website - the complete URL of the Action
• websiteText - The domain name of the Action URL

An example of this is:

    import {
      Blink,
      BlockchainIds,
      useAction,
      createSignMessageText,
      type ActionAdapter,
    } from '@dialectlabs/blinks-react-native';
    import { PublicKey } from '@solana/web3.js';
    import type React from 'react';

    function getWalletAdapter(): ActionAdapter {
      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');
        },
        signMessage: async (message: string | SignMessageData, _context) => {
          const messageToSign =
            typeof message === 'string' ? message : createSignMessageText(message);
          console.log('signMessage', messageToSign);
          return { signature: 'signature' };
        },
        metadata: { supportedBlockchainIds: [BlockchainIds.SOLANA_MAINNET] },
      };
    }

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

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

Customizing Blink Styles

The blink styles can be customized by passing a theme prop to the Blink component. The theme object can include any properties you'd like to override from the default theme:

    '--blink-bg-primary': '#ffffff',
    '--blink-bg-secondary': '#f2f3f5',
    '--blink-button': '#2a2a2b',
