Fireact Builder — Post-Installation Customization Skill

You help developers customize and extend their Fireact SaaS apps via natural language. This skill covers adding pages, replacing components, customizing navigation, branding, Cloud Functions, Firestore collections, and i18n.

---

1. Project Detection

Before doing anything, confirm this is a Fireact project:

1. Check package.json for @fireact.dev/app in dependencies
2. Check src/config/app.config.json exists
3. Check src/App.tsx imports from @fireact.dev/app

If any check fails, tell the user this doesn't appear to be a Fireact project and suggest running npx create-fireact-app first.

---

2. State Reading Protocol

MUST read these files before making any changes to understand the current project state:

File	What to learn
src/App.tsx	Current routing, imports, which components are local vs from @fireact.dev/app
src/config/app.config.json	Route paths, permissions, settings
src/config/stripe.config.json	Subscription plans
src/i18n/en.ts	Existing translation keys
src/components/ (list files)	Existing custom components
functions/src/index.ts	Existing Cloud Functions
firestore.rules	Existing security rules

3. Customization Playbooks

A. Add New Subscription Page

Use when the user wants a page scoped to a subscription (e.g., "add a reports page", "add an analytics page").

Steps:

1. Create component at src/components/<PageName>.tsx:

   • Import useSubscription, useConfig, useTranslation from @fireact.dev/app
   • Handle loading state (spinner) and error state (redirect to home)
   • Use TailwindCSS for styling — no inline styles
   • See references/component-patterns.md for template

2. Add route key to src/config/app.config.json under pages:

   "<pageName>": "/subscription/:id/<slug>"
   

3. Add route in src/App.tsx inside the SubscriptionProvider > SubscriptionLayout route block:

   <Route path={appConfig.pages.<pageName>} element={
     <ProtectedSubscriptionRoute requiredPermissions={['access']}>
       <PageName />
     </ProtectedSubscriptionRoute>
   } />
   

4. Add import at top of src/App.tsx:

   import PageName from './components/PageName';
   

5. Add i18n keys to src/i18n/en.ts (and other language files)

6. Optionally add to navigation menu (see Playbook E)

B. Add New Authenticated Page

Use when the user wants a page that requires login but is not scoped to a subscription (e.g., "add an API keys page", "add a settings page").

Steps:

1. Create component at src/components/<PageName>.tsx:

   • Import useAuth, useConfig from @fireact.dev/app
   • See references/component-patterns.md for template

2. Add route key to src/config/app.config.json under pages:

   "<pageName>": "/<slug>"
   

3. Add route inside AuthenticatedLayout block in src/App.tsx:

   <Route path={appConfig.pages.<pageName>} element={<PageName />} />
   

4. Add import and translations

C. Add New Public Page

Use when the user wants a page that doesn't require login (e.g., "add a landing page", "add a pricing page").

Steps:

1. Create component at src/components/<PageName>.tsx

2. Add route inside PublicLayout block in src/App.tsx:

   <Route path="/<slug>" element={<PageName />} />
   

3. Add translations

D. Replace/Customize Existing Component

Use when the user wants to change an existing component from @fireact.dev/app (e.g., "customize the sign-in page", "change the dashboard").

Steps:

1. Identify which @fireact.dev/app component to replace (see references/component-patterns.md for the full export list)

2. Create local version at src/components/<ComponentName>.tsx maintaining the same hook/context contract as the original

3. Change import in src/App.tsx:

   • Remove the component from the @fireact.dev/app destructured import
   • Add a local import:

     import ComponentName from './components/ComponentName';
     

4. Reference references/component-patterns.md for the expected patterns of each component type

E. Customize Navigation

Use when the user wants to add, remove, or reorder navigation items.

Steps:

1. Create custom menu components (e.g., src/components/CustomSubscriptionDesktopMenu.tsx and CustomSubscriptionMobileMenu.tsx)

2. Follow the pattern: useLocation, useTranslation, useSubscription, useConfig, hasPermission()

3. Path replacement: use .replace(':id', subscription?.id || '') for subscription paths

4. Sidebar width classes:

   • [.w-20_&]:hidden — hide text when sidebar collapsed
   • [.w-64_&]:mr-4 — add margin for icon when sidebar expanded
   • [.w-20_&]:mx-auto — center icon when sidebar collapsed

5. Swap imports in src/App.tsx layout props:

   • Remove SubscriptionDesktopMenu / SubscriptionMobileMenu from @fireact.dev/app import
   • Import custom versions
   • Pass to SubscriptionLayout desktopMenu and mobileMenu props

See references/navigation-customization.md for full reference.

F. Customize Branding & Theme

Use when the user wants to change colors, fonts, or logo.

Steps:

1. Modify tailwind.config.js for custom colors/fonts:

   theme: {
     extend: {
       colors: {
         primary: { /* custom palette */ }
       }
     }
   }
   

2. Modify src/index.css for global styles

3. Create custom Logo component at src/components/Logo.tsx and import locally in App.tsx

4. SubscriptionLayout supports these props for nav theming:

   • navBackgroundColor — CSS class for nav background (e.g., "bg-blue-900")
   • navTextColor — CSS class for nav text (e.g., "text-blue-100")

G. Add Custom Cloud Functions

Use when the user wants to add backend logic.

Steps:

1. Create functions/src/<functionName>.ts:

   import { onCall } from 'firebase-functions/v2/https';
   
   export const myFunction = onCall(async (request) => {
     // Access global config
     const config = global.saasConfig;
     // Your logic here
     return { success: true };
   });
   

2. Access global.saasConfig for permissions, plans, Stripe keys

3. Export from functions/src/index.ts:

   export { myFunction } from './<functionName>';
   

4. Call from frontend:

   import { httpsCallable } from 'firebase/functions';
   
   const config = useConfig();
   const myFunction = httpsCallable(config.functions, 'myFunction');
   const result = await myFunction({ /* data */ });
   

5. Build: cd functions && npm run build

See references/cloud-functions-patterns.md for detailed patterns.

H. Add Firestore Collections & Custom Data

Use when the user wants to store and retrieve custom data.

Steps:

1. Use Firestore SDK with config.db from useConfig():

   import { collection, doc, getDocs, addDoc } from 'firebase/firestore';
   
   const config = useConfig();
   
   // Read
   const snapshot = await getDocs(collection(config.db, 'subscriptions', subscriptionId, 'myCollection'));
   
   // Write
   await addDoc(collection(config.db, 'subscriptions', subscriptionId, 'myCollection'), { ... });
   

2. Add security rules to firestore.rules following existing patterns:

   match /subscriptions/{docId}/myCollection/{docId2} {
     allow read: if request.auth != null
       && get(/databases/$(database)/documents/subscriptions/$(docId)).data.permissions.access.hasAny([request.auth.uid]);
     allow write: if request.auth != null
       && get(/databases/$(database)/documents/subscriptions/$(docId)).data.permissions.admin.hasAny([request.auth.uid]);
   }
   

3. Build components that read/write data using the patterns in references/component-patterns.md

4. Key Conventions (Always Follow)

• i18n: Use useTranslation() with t('key') for ALL user-facing strings. Never hardcode display text.
• Loading/error states: Always handle in subscription components — show spinner while loading, redirect on error.
• TailwindCSS only: No inline styles. Use Tailwind utility classes.
• Route config: Always add route key to src/config/app.config.json when adding a page.
• Subscription route protection: Always wrap subscription routes in <ProtectedSubscriptionRoute requiredPermissions={[...]}>.
• Subscription URL pattern: Paths follow /subscription/:id/<slug>.
• Verify after changes: Run npm run build and cd functions && npm run build to confirm no errors.
