Tambahkan Langganan Stripe ke Aplikasi Web AI Anda

Checklist Prasyarat

Pastikan Anda sudah menyiapkan ini sebelum memulai.

Sebelum mengikuti tutorial Stripe ini, pastikan aplikasi web Anda sudah memiliki hal-hal berikut:

1. Aplikasi Anda sudah di-deploy (URL live diperlukan)

Stripe Checkout hanya berfungsi di website yang benar-benar di-deploy — ini TIDAK berfungsi di dalam lingkungan pratinjau Google AI Studio.

Video Deployment

Jalankan Prompt #5: Perbarui akun secara otomatis dari Free → Pro

Prompt: Deteksi Paket Pro

Tambahkan deteksi paket Pro (read-only) dari Firestore…

Add Pro plan detection (read-only) from Firestore. - Listen in real-time (onSnapshot) to: customers/{uid}/subscriptions - Set isPro = true if any subscription status is "active" or "trialing" - If isPro true: - Show a "Pro" badge - Hide the Upgrade button - If isPro false: - Show a "Free" badge - Show the Upgrade button Important: Do NOT block Free users from using the app features. Do not redesign UI. Return exact files changed.

Jalankan Prompt #6: Tambahkan Manage Subscription dan hubungkan ke Stripe Billing Portal

Prompt: Tombol Kelola Langganan

Tugas: Tambahkan tombol "Manage Subscription" yang berfungsi untuk pengguna PRO…

Task: Add a working "Manage Subscription" button for PRO users using Stripe Customer Portal (Firebase Stripe Extension). Context: - The app already uses the Firebase Stripe Extension (customers/{uid} and checkout_sessions work). - The app uses hash routing (/#/dashboard). - Do NOT change the UI design. Only add logic. - The button must work in production (no CORS errors). Requirements: 1) Show "Manage Subscription" button ONLY when the current user is PRO (isPro === true). 2) On click, DO NOT call any cloudfunctions.net URL directly and DO NOT use fetch to Cloud Functions. 3) Instead, create a Firestore document at: customers/{uid}/portal_sessions/{autoId} with fields: - return_url: "https://vloma.com/#/dashboard" 4) After creating the doc, listen in real-time to that same document until the extension writes a field: - url Then redirect the browser to that url (window.location.href = url). 5) Add basic UX: - disable the button while loading - show a friendly alert if no url appears after 20 seconds - log the real error to console Implementation notes: - Use the existing Firebase client (auth + firestore). - Keep existing files structure. Modify only the minimal files needed. - Return the exact files changed and the exact code changes. Deliverable: - A working Manage Subscription button that opens Stripe Customer Portal and returns to /#/dashboard.

Jalankan Prompt #7: Tambahkan batas Free vs Pro

Prompt: Tambahkan Batas Penggunaan

Tugas: Tambahkan batas penggunaan Free/Pro TANPA menyentuh atau mengubah sistem billing/upgrade yang ada…

Task: Add Free/Pro usage limits WITHOUT touching or changing the existing billing/upgrade system. CRITICAL RULES (must follow): - DO NOT modify the existing Stripe checkout / upgrade code. - DO NOT modify how "isPro" is determined in the project. - DO NOT create or use users/{uid}.plan field (do not add plan to Firestore at all). - DO NOT change Firestore rules or Storage rules. - Keep UI the same (only small toast/alert/modal allowed). Limits: - FREE: max 5 files, max 5 folders, max 100MB total stored - PRO: max 50 files, max 50 folders, max 5GB total stored How to implement (safe approach): 1) Use the CURRENT existing "isPro" boolean/state already working in the app. - Whatever source it currently uses (Stripe Extension subscriptions / custom claims / existing code), keep it exactly as-is. - Only READ isPro, do not re-implement it. 2) Track usage from the existing Firestore structure (do not rename collections): - Files count = number of docs in users/{uid}/files - Folders count = number of docs in users/{uid}/folders - Total storage used = sum of file sizes from the file docs (field: size bytes). If old docs don’t have size, treat missing size as 0, and ensure new uploads always write size. 3) Enforce limits ONLY in the UI/Client for now: - Before creating a new file doc or uploading: check limits using current isPro. - Before creating a new folder doc: check limits using current isPro. - If Free exceeds limit: block action and show: “Free plan limit reached. Upgrade to Pro to continue.” Add an “Upgrade” button that triggers the EXISTING checkout flow (call the same function already used in the app). 4) IMPORTANT: After checkout completes, the app MUST refresh/reflect Pro automatically: - Do not add new plan logic. - Just ensure the same existing listener/state updates isPro and the UI re-checks limits. - Add a small debug log (console.log) showing current isPro value after returning from checkout. Deliverable: - Limits work and show upgrade prompt. - Paying and upgrading still changes the app to Pro exactly like before. - Return exact files changed.

Tambahkan Aturan Firestore (pengguna hanya dapat mengakses datanya sendiri)

Penting: Aturan keamanan Firestore ini adalah contoh. Anda HARUS meninjau dan menyesuaikannya agar sesuai dengan struktur data aplikasi web Anda sendiri. Setiap aplikasi membutuhkan aturan yang sesuai dengan koleksi dan model data spesifiknya.

firestore.rules

rules_version = '2'; service cloud.firestore { match /databases/{database}/documents { function signedIn() { return request.auth != null; } function isOwner(uid) { return signedIn() && request.auth.uid == uid; } // ------------------------- // Users data (your app data) // ------------------------- match /users/{uid} { allow read, write: if isOwner(uid); // Everything under this user is also only for the owner match /{allPaths=**} { allow read, write: if isOwner(uid); } } // ------------------------- // Stripe Extension // customers/{uid}/... // ------------------------- match /customers/{uid} { // user can read their stripe docs allow read: if isOwner(uid); // user must NOT write to stripe docs directly allow write: if false; // user can create a checkout session doc match /checkout_sessions/{id} { allow create, read: if isOwner(uid); allow update, delete: if false; } // user can create a portal session doc match /portal_sessions/{id} { allow create, read: if isOwner(uid); allow update, delete: if false; } // subscriptions/payments are server-controlled (read only) match /subscriptions/{id} { allow read: if isOwner(uid); allow write: if false; } match /payments/{id} { allow read: if isOwner(uid); allow write: if false; } } } }

Tambahkan Aturan Storage (pengguna hanya dapat mengakses filenya sendiri)

Penting: Aturan keamanan Storage ini adalah contoh. Anda HARUS meninjau dan menyesuaikannya agar sesuai dengan path proyek Anda sendiri (misalnya, nama folder uploads) dan batas Anda. Setiap aplikasi membutuhkan aturan storage yang sesuai dengan strukturnya sendiri.

storage.rules

rules_version = '2'; service firebase.storage { match /b/{bucket}/o { function signedIn() { return request.auth != null; } function isOwner(uid) { return signedIn() && request.auth.uid == uid; } match /user_uploads/{uid}/{allPaths=**} { allow read: if isOwner(uid); // write create/update/delete // request.resource null delete، allow write: if isOwner(uid) && (request.resource == null || request.resource.size <= 200 * 1024 * 1024); } } }

(Opsional) Jalankan prompt singkat untuk perbaikan UI kecil (misalnya, memperbarui harga di modal)

Anda dapat menjalankan prompt tambahan nanti untuk memoles detail UI (seperti memperbarui harga di modal), tetapi kami tidak akan menyediakan prompt spesifik di sini karena sangat bergantung pada penyesuaian UI spesifik Anda.
