@pingpay/onramp-sdk v0.1.1

Usage

Installation

npm install @pingpay/onramp-sdk

Basic Usage

import { PingpayOnramp } from '@pingpay/onramp-sdk';
import type { TargetAsset, OnrampResult } from '@pingpay/onramp-sdk';

const onramp = new PingpayOnramp();

const targetAsset: TargetAsset = {
  chain: 'NEAR',
  asset: 'USDC'
};

async function handleOnramp() {
  try {
    const result: OnrampResult = await onramp.initiateOnramp(targetAsset);
    console.log('Onramp successful:', result);
  } catch (error) {
    console.error('Onramp failed:', error);
  }
}

return <button onClick={handleOnramp}>Pingpay Onramp</button>

Advanced Usage

The SDK provides helper methods to hook into the onramp lifecycle.

import { PingpayOnramp } from '@pingpay/onramp-sdk';
import type {
  TargetAsset,
  OnrampResult,
  PingpayOnrampConfig,
  OnrampFlowPayload,
  OnrampStep,
  OnrampStepDetails,
  FormDataSubmittedPayload,
  WalletConnectedPayload,
  TransactionSignedPayload,
  OnrampInitiatedPayload,
  ProcessFailedPayload,
  PingpayOnrampError,
} from '@pingpay/onramp-sdk';

const config: PingpayOnrampConfig = {
  onPopupReady: () => {
    console.log('SDK: Popup is ready.');
  },
  onFlowStarted: (payload: OnrampFlowPayload) => {
    console.log('SDK: Onramp flow started:', payload);
  },
  onStepChange: (step: OnrampStep, details?: OnrampStepDetails) => {
    console.log('SDK: Onramp step changed:', step, details);
  },
  onFormDataSubmitted: (payload: FormDataSubmittedPayload) => {
    console.log('SDK: Form data submitted:', payload);
  },
  onWalletConnected: (payload: WalletConnectedPayload) => {
    console.log('SDK: Wallet connected:', payload);
  },
  onTransactionSigned: (payload: TransactionSignedPayload) => {
    console.log('SDK: Transaction signed:', payload);
  },
  onOnrampInitiated: (payload: OnrampInitiatedPayload) => {
    console.log('SDK: Onramp initiated with service:', payload);
  },
  onProcessComplete: (result: OnrampResult) => {
    console.log('SDK: Onramp process complete:', result);
  },
  onProcessFailed: (payload: ProcessFailedPayload) => {
    console.error('SDK: Onramp process failed:', payload.error, payload.details, payload.step);
  },
  onPopupClose: () => {
    console.log('SDK: Popup was closed.');
  }
};

const onramp = new PingpayOnramp(config);

const targetAsset: TargetAsset = {
  chain: 'NEAR',
  asset: 'USDC'
};

async function handleOnramp() {
  try {
    const result: OnrampResult = await onramp.initiateOnramp(targetAsset);
    console.log('Onramp successful:', result);
  } catch (error) {
    if (error instanceof PingpayOnrampError) { // Use PingpayOnrampError for specific error handling
      console.error('Onramp failed specifically:', error.message, error.details, error.step);
    } else {
      console.error('Onramp failed generally:', error);
    }
  }
}

return <button onClick={handleOnramp}>Pingpay Onramp</button>

Configuration

• Event Handlers (all optional):
  • onPopupReady(): Called when the popup window signals it's ready. (SDK logs this internally too)
  • onFlowStarted(payload: OnrampFlowPayload): Called when the onramp flow begins in the popup.
  • onStepChange(step: OnrampStep, details?: OnrampStepDetails): Called when the current step in the onramp process changes.
  • onFormDataSubmitted(payload: FormDataSubmittedPayload): Called when user submits form data.
  • onWalletConnected(payload: WalletConnectedPayload): Called when a wallet is successfully connected.
  • onTransactionSigned(payload: TransactionSignedPayload): Called when a transaction is signed by the user.
  • onOnrampInitiated(payload: OnrampInitiatedPayload): Called when the onramp process is initiated with the backend service.
  • onProcessComplete(result: OnrampResult): Called when the entire onramp process is successfully completed.
  • onProcessFailed(payload: ProcessFailedPayload): Called if the onramp process fails at any point.
  • onPopupClose(): Called when the popup is closed, either by the user, an error, or programmatically.

Closing the Onramp

You can programmatically close the onramp popup and clean up resources by calling the close() method:

onramp.close();

This is useful if your application needs to interrupt the onramp flow. The onPopupClose callback will also be triggered.

Development

To install dependencies:

bun install

To run (example, adjust as per your project's actual run script for the SDK examples or tests):

bun run index.ts
