Mesh Connect React Native SDK

React Native library for integrating with Mesh Connect.

Installation

With npm:

npm install --save @meshconnect/react-native-link-sdk

With yarn:

yarn add @meshconnect/react-native-link-sdk

💡 This package requires react-native-webview to be installed in your project. Some times it is not installed automatically (This is a known npm issue). You should install it manually via following command in this case:

npm install --save react-native-webview

# or with yarn
yarn add react-native-webview

Get Link token

Link token should be obtained from the POST /api/v1/linktoken endpoint. API reference for this request is available here. The request must be performed from the server side because it requires the client's secret. You will get the response in the following format:

{
  "content": {
    "linkToken": "{linkToken}"
  },
  "status": "ok",
  "message": ""
}

Launch Link

import React from 'react';
import {
  LinkConnect,
  LinkPayload,
  LinkSettings,
  LinkEventType,
  IntegrationAccessToken,
  TransferFinishedPayload,
  TransferFinishedSuccessPayload,
  TransferFinishedErrorPayload
} from '@meshconnect/react-native-link-sdk';

const accessTokens: IntegrationAccessToken = [
/* Your access tokens */
];

const transferDestinationTokens: IntegrationAccessToken = [
/* Your transfer destination tokens */
];

const linkSettings: LinkSettings = {
    accessTokens,
    transferDestinationTokens,
};

export const App = () => {
  return (
    <LinkConnect
      linkToken={"YOUR_LINKTOKEN"}
      settings={linkSettings}
      onIntegrationConnected={(payload: LinkPayload) => {
        // use broker account data
      }}
      onTransferFinished={(payload: TransferFinishedPayload) => {
        if (payload.status === 'success') {
          const successPayload = payload as TransferFinishedSuccessPayload
          // use transfer finished data
        } else {
          const errorPayload = payload as TransferFinishedErrorPayload
          // handle transfer error
        }
      }}
      onEvent={(event: LinkEventType) => {
          console.log(event);
      }}
      onExit={(err?: string) => {
        // use error message
      }}
    />
  )
}

export default App;

• transferDestinationTokens - an array of IntegrationAccessToken objects that is used as a destination for crypto transfer flow.
• disableDomainWhiteList - a boolean flag that allows to disable origin whitelisting. By default, the origin is whitelisted, with the following domains set:
  • *.meshconnect.com
  • *.getfront.com
  • *.walletconnect.com
  • *.walletconnect.org
  • *.walletlink.org

V1 -> V2 migration guide

In Mesh Connect React Native SDK v2, url prop is removed from LinkConnect component. You should use linkToken prop instead of url prop. orError and onClose props are combined with onExit callback with an optional error message argument.

Following are the renamed props:

• onBrokerConnected -> onIntegrationConnected
• FrontPayload -> LinkPayload

The component FrontFinance is renamed to LinkConnect.

Typescript support

Typescript definitions for @meshconnect/react-native-link-sdk are built into the npm package.

Adding URL Schemes to Info.plist

To enable our SDK to interact with specific apps, please add the following URL schemes to your Info.plist file:

1. Open your Info.plist file: This file is located in the ios directory of your React Native project.
2. Add the following XML snippet within the <dict> tags (example for adding trust, robinhood, and metamask):

   <key>LSApplicationQueriesSchemes</key>
   <array>
       <string>trust</string>
       <string>robinhood</string>
       <string>metamask</string>
   </array>
   

This configuration allows our SDK to query and interact with the specified apps, ensuring seamless integration and functionality.
