Bundles

Bundles adalah paket pembaruan inti di Capgo. Setiap bundle berisi aset web (HTML, CSS, JS) yang membentuk konten aplikasi Anda. API Bundles memungkinkan Anda mengelola paket pembaruan ini, termasuk daftar dan penghapusannya.

Memahami Bundles

Sebuah bundle mewakili versi spesifik dari konten web aplikasi Anda dan mencakup:

• Version: Nomor versi semantik dari bundle
• Checksum: Hash unik untuk memverifikasi integritas bundle
• Storage Info: Detail tentang di mana dan bagaimana bundle disimpan
• Native Requirements: Persyaratan versi aplikasi native minimum
• Metadata: Waktu pembuatan, kepemilikan, dan informasi pelacakan lainnya

Pembuatan Bundle Manual (Tanpa CLI)

Berikut cara membuat dan mengunggah bundle secara manual tanpa menggunakan Capgo CLI:

Langkah 1: Bangun Aplikasi Anda

Pertama, bangun aset web aplikasi Anda:

npm run build

Langkah 2: Buat Bundle Zip Menggunakan Paket yang Sama dengan Capgo CLI

Penting: Gunakan paket JavaScript yang persis sama dengan yang digunakan Capgo CLI secara internal untuk memastikan kompatibilitas.

Instal Paket yang Diperlukan

npm install adm-zip @tomasklaen/checksum

Buat Bundle Zip dengan JavaScript (Sama dengan Capgo CLI)

const fs = require('node:fs');
const path = require('node:path');
const os = require('node:os');
const AdmZip = require('adm-zip');
const { checksum: getChecksum } = require('@tomasklaen/checksum');

// Exact same implementation as Capgo CLI
function zipFileUnix(filePath) {
  const zip = new AdmZip();
  zip.addLocalFolder(filePath);
  return zip.toBuffer();
}

async function zipFileWindows(filePath) {
  console.log('Zipping file windows mode');
  const zip = new AdmZip();

  const addToZip = (folderPath, zipPath) => {
    const items = fs.readdirSync(folderPath);

    for (const item of items) {
      const itemPath = path.join(folderPath, item);
      const stats = fs.statSync(itemPath);

      if (stats.isFile()) {
        const fileContent = fs.readFileSync(itemPath);
        zip.addFile(path.join(zipPath, item).split(path.sep).join('/'), fileContent);
      } else if (stats.isDirectory()) {
        addToZip(itemPath, path.join(zipPath, item));
      }
    }
  };

  addToZip(filePath, '');
  return zip.toBuffer();
}

// Main zipFile function (exact same logic as CLI)
async function zipFile(filePath) {
  if (os.platform() === 'win32') {
    return zipFileWindows(filePath);
  } else {
    return zipFileUnix(filePath);
  }
}

async function createBundle(inputPath, outputPath, version) {
  // Create zip using exact same method as Capgo CLI
  const zipped = await zipFile(inputPath);

  // Write to file
  fs.writeFileSync(outputPath, zipped);

  // Calculate checksum using exact same package as CLI
  const checksum = await getChecksum(zipped, 'sha256');

  return {
    filename: path.basename(outputPath),
    version: version,
    size: zipped.length,
    checksum: checksum
  };
}

// Usage
async function main() {
  try {
    const result = await createBundle('./dist', './my-app-1.2.3.zip', '1.2.3');
    console.log('Bundle info:', JSON.stringify(result, null, 2));
  } catch (error) {
    console.error('Error creating bundle:', error);
  }
}

main();

Langkah 3: Hitung Checksum SHA256 Menggunakan Paket yang Sama dengan CLI

const fs = require('node:fs');
const { checksum: getChecksum } = require('@tomasklaen/checksum');

async function calculateChecksum(filePath) {
  const fileBuffer = fs.readFileSync(filePath);
  // Use exact same package and method as Capgo CLI
  const checksum = await getChecksum(fileBuffer, 'sha256');
  return checksum;
}

// Usage
async function main() {
  const checksum = await calculateChecksum('./my-app-1.2.3.zip');
  console.log('Checksum:', checksum);
}

main();

Langkah 4: Unggah Bundle ke Penyimpanan Anda

Upload your zip file to any web-accessible storage:

# Example: Upload to your server via scp
scp my-app-1.2.3.zip user@your-server.com:/var/www/bundles/

# Example: Upload to S3 using AWS CLI
aws s3 cp my-app-1.2.3.zip s3://your-bucket/bundles/

# Example: Upload via curl to a custom endpoint
curl -X POST https://your-storage-api.com/upload \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -F "file=@my-app-1.2.3.zip"

Important: Your bundle must be publicly accessible via HTTPS URL (no authentication required). Capgo’s servers need to download the bundle from this URL.

Examples of valid public URLs:

• https://your-storage.com/bundles/my-app-1.2.3.zip
• https://github.com/username/repo/releases/download/v1.2.3/bundle.zip
• https://cdn.jsdelivr.net/gh/username/repo@v1.2.3/dist.zip

Langkah 5: Daftarkan Bundle dengan API Capgo

Register the external bundle with Capgo using direct API calls:

async function registerWithCapgo(appId, version, bundleUrl, checksum, apiKey) {
  const fetch = require('node-fetch');

  // Create bundle version
  const response = await fetch('https://api.capgo.app/bundle/', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'authorization': apiKey
    },
    body: JSON.stringify({
      app_id: appId,
      version: version,
      external_url: bundleUrl,
      checksum: checksum
    })
  });

  if (!response.ok) {
    throw new Error(`Failed to create bundle: ${response.statusText}`);
  }

  const data = await response.json();
  console.log('Bundle created:', data);

  return data;
}

Parameter API

Parameter	Description	Required
app_id	Your app identifier	Yes
version	Semantic version (e.g., “1.2.3”)	Yes
external_url	Publicly accessible HTTPS URL where bundle can be downloaded (no auth required)	Yes
checksum	SHA256 checksum of the zip file	Yes

Persyaratan Struktur Bundle

Your bundle zip must follow these requirements:

1. Root Index File: Must have index.html at the root level
2. Capacitor Integration: Must call notifyAppReady() in your app code
3. Asset Paths: Use relative paths for all assets

Struktur Bundle yang Valid

bundle.zip
├── index.html
├── assets/
│   ├── app.js
│   └── styles.css
└── images/

Contoh Alur Kerja Manual Lengkap

Simple Node.js script to zip, checksum, and upload to Capgo:

const fs = require('node:fs');
const os = require('node:os');
const AdmZip = require('adm-zip');
const { checksum: getChecksum } = require('@tomasklaen/checksum');
const fetch = require('node-fetch');

async function deployToCapgo() {
  const APP_ID = 'com.example.app';
  const VERSION = '1.2.3';
  const BUNDLE_URL = 'https://your-storage.com/bundles/app-1.2.3.zip';
  const API_KEY = process.env.CAPGO_API_KEY;

  // 1. Create zip (same as Capgo CLI)
  const zip = new AdmZip();
  zip.addLocalFolder('./dist');
  const zipped = zip.toBuffer();

  // 2. Calculate checksum (same as Capgo CLI)
  const checksum = await getChecksum(zipped, 'sha256');
  console.log('Checksum:', checksum);

  // 3. Upload to your storage (replace with your upload logic)
  // fs.writeFileSync('./bundle.zip', zipped);
  // ... upload bundle.zip to your storage ...

  // 4. Register with Capgo API
  const response = await fetch('https://api.capgo.app/bundle/', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'authorization': API_KEY
    },
    body: JSON.stringify({
      app_id: APP_ID,
      version: VERSION,
      external_url: BUNDLE_URL,
      checksum: checksum
    })
  });

  if (!response.ok) {
    throw new Error(`Failed: ${response.statusText}`);
  }

  console.log('Bundle registered with Capgo!');
}

deployToCapgo().catch(console.error);

Install dependencies:

npm install adm-zip @tomasklaen/checksum node-fetch

Verifikasi Checksum

Perhitungan Checksum JavaScript (Sama dengan Capgo CLI)

Use the exact same package and method that Capgo CLI uses internally:

const fs = require('node:fs');
const { checksum: getChecksum } = require('@tomasklaen/checksum');

async function calculateChecksum(filePath) {
  const fileBuffer = fs.readFileSync(filePath);
  // Use exact same package and method as Capgo CLI
  const checksum = await getChecksum(fileBuffer, 'sha256');
  return checksum;
}

// Verify checksum matches
async function verifyChecksum(filePath, expectedChecksum) {
  const actualChecksum = await calculateChecksum(filePath);
  const isValid = actualChecksum === expectedChecksum;

  console.log(`File: ${filePath}`);
  console.log(`Expected: ${expectedChecksum}`);
  console.log(`Actual:   ${actualChecksum}`);
  console.log(`Valid:    ${isValid}`);

  return isValid;
}

// Usage
async function main() {
  const bundleChecksum = await calculateChecksum('./my-app-1.2.3.zip');
  console.log('SHA256 Checksum:', bundleChecksum);
}

main();

Pentingnya Checksum

• Bundle Integrity: Ensures the bundle hasn’t been corrupted during transfer
• API Verification: Capgo verifies checksums before accepting bundles
• Plugin Verification: The mobile plugin verifies checksums before applying updates

Best Practices

1. Version Management: Use semantic versioning consistently
2. Storage Optimization: Remove unused bundles periodically
3. Version Compatibility: Set appropriate minimum native version requirements
4. Backup Strategy: Maintain backups of critical bundle versions
