### Create and Sign Apple Pass in NodeJS (Cloudflare Worker)

Source: https://github.com/ionic-enterprise/tutorials-digital-passes/blob/main/backend/readme.md

This NodeJS code snippet, intended for a Cloudflare Worker, demonstrates the process of creating and signing an Apple Pass. It utilizes the 'passkit-generator' library and requires signing certificates, keys, and pass configuration data.

```typescript
import { Pass, PassType } from "@alexandercerutti/passkit-generator";

// ... (other imports and setup)

async function createAndSignPass(passData: any, signerCert: string, signerKey: string, signerKeyPassphrase: string, wwdr: string): Promise<Buffer> {
  const pass = new Pass({
    // ... pass configuration
  });

  const signedPass = await pass.sign(
    signerCert,
    signerKey,
    signerKeyPassphrase,
    wwdr
  );

  return signedPass;
}

// Example usage within a Cloudflare Worker:
// addEventListener('fetch', event => {
//   event.respondWith(handleRequest(event.request))
// })
//
// async function handleRequest(request) {
//   const signerCert = await env.SIGNER_CERT;
//   const signerKey = await env.SIGNER_KEY;
//   const signerKeyPassphrase = await env.SIGNER_PASSPHRASE;
//   const wwdr = await env.WWDR;
//
//   // Load pass data from a file or other source
//   const passData = { ... }; 
//
//   const signedPassBuffer = await createAndSignPass(passData, signerCert, signerKey, signerKeyPassphrase, wwdr);
//
//   return new Response(signedPassBuffer, {
//     headers: {
//       'Content-Type': 'application/vnd.apple.passbook',
//       'Content-Disposition': 'attachment; filename="pass.pkpass"'
//     }
//   });
// }
```

### Generate Private Key using OpenSSL

Source: https://github.com/ionic-enterprise/tutorials-digital-passes/blob/main/backend/readme.md

Generates a 2048-bit RSA private key using OpenSSL. This key is essential for creating a Certificate Signing Request (CSR) and signing the pass.

```bash
openssl genrsa -out my-key.key 2048
```

--------------------------------

### Download pkpass File using Javascript Fetch API

Source: https://github.com/ionic-enterprise/tutorials-digital-passes/blob/main/app/readme.md

Downloads a pkpass file from a given URL using the Javascript Fetch API and converts the response blob to a base64 encoded string. It relies on a helper function `blobToBase64` for the conversion.

```typescript
public async get(url: string): Promise<string> {
    const response = await fetch(url);
    const blob = await response.blob();
    const base64 = await blobToBase64(blob);
    if (!base64 || base64 instanceof ArrayBuffer) {
      throw new Error(`Unable to get ${url}`);
    }
    return base64;
  }
```

--------------------------------

### Create Certificate Signing Request (CSR) using OpenSSL

Source: https://github.com/ionic-enterprise/tutorials-digital-passes/blob/main/backend/readme.md

Creates a Certificate Signing Request (CSR) using an existing private key. This CSR is then uploaded to the Apple Developer portal to obtain a signing certificate. A challenge password must be specified during this process.

```bash
openssl req -new -key my-key.key -out request.certSigningRequest
```

--------------------------------

### Convert Apple Pass Certificate from DER to PEM format

Source: https://github.com/ionic-enterprise/tutorials-digital-passes/blob/main/backend/readme.md

Converts the downloaded Apple pass certificate from DER format to PEM format. This PEM-formatted certificate is required for signing the pass.

```bash
openssl x509 -inform DER -outform PEM -in pass.cer -out pass.pem
```

--------------------------------

### Convert WWDR Certificate from DER to PEM format

Source: https://github.com/ionic-enterprise/tutorials-digital-passes/blob/main/backend/readme.md

Converts the Apple Worldwide Developer Relations (WWDR) certificate from DER format to PEM format. This certificate is necessary for the signing process.

```bash
openssl x509 -inform DER -outform PEM -in AppleWWDRCAG4.cer -out wwdr.pem
```

--------------------------------

### Add pkpass Data to Apple Wallet using Capacitor Plugin

Source: https://github.com/ionic-enterprise/tutorials-digital-passes/blob/main/app/readme.md

Adds a downloaded pkpass file, provided as a base64 encoded string, to the device's Apple Wallet using the 'capacitor-pass-to-wallet' plugin. This triggers the native Apple Wallet 'add pass' dialog.

```typescript
import { CapacitorPassToWallet } from 'capacitor-pass-to-wallet';
...
await CapacitorPassToWallet.addToWallet({ base64: data });
```

### Platform-Specific Wallet Integration (TypeScript)

Source: https://context7.com/ionic-enterprise/tutorials-digital-passes/llms.txt

The HomePage component detects the platform (iOS or Android) to handle pass downloads. For iOS, it fetches pass data and adds it to Apple Wallet. For Android, it opens the Google Pay save flow.

```typescript
// app/src/app/home/home.page.ts
import { Component } from '@angular/core';
import { WalletService } from '../wallet.service';
import { Capacitor } from '@capacitor/core';

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  standalone: true,
})
export class HomePage {
  busy = false;

  constructor(private walletService: WalletService) {}

  async download() {
    try {
      this.busy = true;
      if (Capacitor.getPlatform() == 'ios') {
        // Download pkpass from backend service
        const data = await this.walletService.get(
          'https://ionic-pass-example.damiantarnawsky.workers.dev'
        );
        // Add the pass to Apple Wallet
        await this.walletService.addToWallet(data);
      } else {
        // Google Pay integration
        const token = ''; // Generate JWT token for Google Pay
        window.open(`https://pay.google.com/gp/v/save/${token}`, '_target');
      }
    } catch (error: any) {
      alert(error.message);

### Generate PKPass File with Cloudflare Workers (TypeScript)

Source: https://context7.com/ionic-enterprise/tutorials-digital-passes/llms.txt

This Cloudflare Worker endpoint dynamically generates a signed PKPass file for boarding passes. It utilizes the 'passkit-generator' library and requires Apple certificates (WWDR, signer cert, key, and passphrase) to be configured as environment secrets. The endpoint supports CORS requests and returns the PKPass file as a buffer.

```typescript
import {
  PKPass
} from "passkit-generator";
import { Buffer } from "node:buffer";

export interface Env {
  WWDR: string; // Apple WWDR certificate
  SIGNER_CERT: string; // Pass signing certificate
  SIGNER_KEY: string; // Pass signing key
  SIGNER_PASSPHRASE: string;
}

export default {
  async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
    if (request.method == 'OPTIONS') {
      return new Response('OK', {
        headers: {
          'Access-Control-Allow-Origin': "*",
          "Access-Control-Allow-Methods": "GET,HEAD,POST,DELETE,OPTIONS",
          "Access-Control-Allow-Headers": "*",
        }
      });
    }

    const pass = new PKPass(

      }
    );

    pass.setBarcodes("1276451828321");
    pass.type = "boardingPass";
    pass.transitType = "PKTransitTypeAir";

    pass.primaryFields.push(
      { key: "IATA-source", value: "LAS", label: "Las Vegas" },
      { key: "IATA-destination", value: "LAX", label: "Los Angeles" }
    );

    return new Response(pass.getAsBuffer(), {
      headers: {
        "Content-type": pass.mimeType,
        "Content-disposition": `attachment; filename=myPass.pkpass`,
        'Access-Control-Allow-Origin': "*",
      },
    });
  },
};
