Configuration

Configuration Files Overview

The project uses a layered configuration approach separating main/default files (should not be modified in branches) from custom files (safe to modify in branches).

Main Files (DO NOT MODIFY IN BRANCHES)

These files contain the base configuration and should only be modified in the main NEO repository:

File	Purpose
packages/app/settings-default.js	Default application settings
packages/app/translation-default.js	Default translations
packages/app/static-default.js	Default static content
packages/app/icons.default.js	Default icon mappings
packages/app/icons-svg.default.js	Default SVG icons
packages/app/design/tailwind/theme.js	Main Tailwind theme
packages/app/loading.default.js	Default loading components
packages/app/lib/functions/functions-default.js	Default utility functions
packages/app/components/*/\_map_default.js	Default component mappings

Custom Files (SAFE TO MODIFY IN BRANCHES)

These files are designed for customization in branch/client projects:

File	Purpose
packages/app/settings.js	Override settings
packages/app/translation.js	Override translations
packages/app/static.js	Override static content
packages/app/icons.js	Override/add icons
packages/app/icons-svg.js	Override/add SVG icons
packages/app/design/tailwind-custom/theme.js	Custom Tailwind theme
packages/app/loading.js	Override loading components
packages/app/lib/functions/functions.js	Override utility functions
packages/app/components/*/\_map.js	Override component mappings
apps/expo/app.config.custom.js	Native app build configuration
apps/next/next.config.custom.js	Next.js custom configuration

---

Customization Guide

Settings Customization

Override settings in packages/app/settings.js:

import { settingsDefault } from './settings-default';

// Override specific settings
settingsDefault.layout.defaults.name = 'ver';
settingsDefault.app.title = 'My App';

export const settings = settingsDefault;

Translation Customization

Override translations in packages/app/translation.js:

import { resourcesDefault } from './translation-default';

resourcesDefault.en.translation['bx_market_reviews_title'] = 'Reviews';
resourcesDefault.en.translation['custom_key'] = 'Custom Value';

export const resources = resourcesDefault;

Tailwind Theme Customization

Customize theme in packages/app/design/tailwind-custom/theme.js:

const colors = {
  bgrcard: {
    DEFAULT: '#ffffff',
    d: '#1a1a1a',
  },
  // Add custom colors...
};

const theme = {
  extend: {
    colors: colors,
    // Add custom theme extensions...
  },
};

module.exports = { theme, colors };

Icon Customization

Lucide Icons (packages/app/icons.js)

'use client'

import { IconSet as IconSetDefault } from './icons.default';
import { Airplane } from 'lucide-react-native';

export const IconSet = {
  'Airplane': Airplane,
  ...IconSetDefault
};

Custom SVG Icons (packages/app/icons-svg.js)

'use client'
import * as SvgIconsDef from 'app/icons-svg.default';
import Svg, { Path } from 'react-native-svg';

const CustomIcon = ({ width = "100%", height = "100%", color = "#868686" }) => (
  <Svg width={width} height={height} viewBox="0 0 24 24" fill="none">
    <Path d="M12 2L2 7l10 5 10-5-10-5z" fill={color} />
  </Svg>
);

export default {
  ...SvgIconsDef,
  CustomIcon
};

Native App Configuration

Customize apps/expo/app.config.custom.js:

module.exports = {
  name: "My App",
  owner: "myorg",
  slug: "my-app",
  scheme: "myapp",
  version: "1.0.0",
  icon: "./assets/custom/icon.png",
  splash: {
    image: "./assets/custom/splash.png",
    backgroundColor: "#ffffff",
  },
  ios: {
    bundleIdentifier: "com.myorg.myapp",
    buildNumber: "1",
  },
  android: {
    package: "com.myorg.myapp",
    versionCode: 1,
  },
  extra: {
    eas: { projectId: "your-project-id" },
    UNA_API_KEY: "your-api-key",
    NEXT_PUBLIC_UNA_URL: "https://api.yoursite.com",
    UNA_URL: "https://api.yoursite.com",
  },
};

Next.js Configuration

Customize apps/next/next.config.custom.js:

const nextConfigCustom = {
  images: {
    remotePatterns: [
      {
        protocol: 'https',
        hostname: 'yourdomain.com',
        pathname: '**',
      },
    ],
  },
};

module.exports = nextConfigCustom;

Component Overrides

Override components by creating custom files and updating the _map.js file:

1. Create packages/app/ui/molecules/custom/my-component.js

2. Update packages/app/ui/molecules/_map.js:

   import { componentsMapDefault } from './_map_default';
   import MyComponent from 'app/ui/molecules/custom/my-component';
   
   componentsMapDefault['my-component'] = MyComponent;
   
   export const componentsMap = componentsMapDefault;
   

Static Assets

Asset Type	Location
Favicon	apps/next/public/static/favicon.svg (or .ico via customization)
Manifest	apps/next/public/static/manifest.json
SVG Images	apps/next/public/svg/local/
App Icons	apps/expo/assets/

Branch Development

Recommended .gitignore for Branch Projects

When creating a branch/client project, add these entries to .gitignore to prevent modifying main repository files:

# ===================================
# PROTECT MAIN REPOSITORY FILES
# ===================================

# Settings defaults (modify settings.js instead)
packages/app/settings-default.js

# Translation defaults (modify translation.js instead)
packages/app/translation-default.js

# Static defaults (modify static.js instead)
packages/app/static-default.js

# Icon defaults (modify icons.js instead)
packages/app/icons.default.js
packages/app/icons-svg.default.js

# Loading defaults (modify loading.js instead)
packages/app/loading.default.js

# Main theme (modify tailwind-custom/theme.js instead)
packages/app/design/tailwind/theme.js

# Default component maps (modify _map.js instead)
packages/app/components/**/_map_default.js
packages/app/ui/**/_map_default.js

# Function defaults (modify functions.js instead)
packages/app/lib/functions/functions-default.js

# Feed items defaults
packages/app/lib/feed-items_default.js

# ===================================
# ALLOWED CUSTOM FILES (DO NOT IGNORE)
# ===================================
# packages/app/settings.js
# packages/app/translation.js
# packages/app/static.js
# packages/app/icons.js
# packages/app/icons-svg.js
# packages/app/loading.js
# packages/app/design/tailwind-custom/theme.js
# packages/app/components/**/_map.js
# packages/app/ui/**/_map.js
# packages/app/lib/functions/functions.js
# apps/expo/app.config.custom.js
# apps/next/next.config.custom.js

Branch Workflow

1. Create branch from main
2. Never modify *-default.js or main configuration files
3. Only modify designated custom files
4. Keep changes isolated to custom files for easy rebasing

---

Deployment

Vercel Deployment

The web app is configured for Vercel with apps/next/vercel.json:

{
  "framework": "nextjs",
  "installCommand": "cd ../.. && yarn install",
  "buildCommand": "yarn build",
  "outputDirectory": ".next"
}

Steps:

1. Connect your repository to Vercel
2. Set root directory to apps/next
3. Configure environment variables in Vercel dashboard
4. Deploy

Self-Hosted Node Server

Single Instance

# Build the application
yarn build

# Start production server
yarn prod

PM2 Cluster Mode

# Install PM2 globally
npm install -g pm2

# Build and start with PM2
yarn build
yarn prod:pm2

PM2 configuration in apps/next/pm2.config.js:

• Local/Dev: 2 instances, 250MB memory limit
• Production: 4 instances, 1GB memory limit

PM2 Management Commands

pm2 list              # View running processes
pm2 logs neoapp       # View logs
pm2 restart neoapp    # Restart application
pm2 stop neoapp       # Stop application
pm2 delete neoapp     # Remove from PM2

Native App Distribution

EAS Build (Recommended)

cd apps/expo

# Development build
eas build --profile development --platform ios
eas build --profile development --platform android

# Production build
eas build --profile production --platform ios
eas build --profile production --platform android

# Submit to stores
eas submit --platform ios
eas submit --platform android

Local Build

cd apps/expo

# iOS (requires macOS + Xcode)
expo run:ios --configuration Release

# Android
expo run:android --variant release

---

Routing Architecture

NEO uses a hybrid routing strategy:

• Native (Expo): File-based routing with expo-router in apps/expo/app/
• Web (Next.js): App Router in apps/next/app/
• Cross-platform navigation: solito for shared navigation patterns

Agent and UNA integration guidance (including routing context) lives in agents.md at the repo root and in the una-api skill.

Adding Dependencies

Pure JS Dependencies (Cross-Platform)

cd apps/expo
yarn add package-name
cd ../..
yarn

Then add to transpilePackages in apps/next/next.config.js:

transpilePackages: [
  'react-native',
  'react-native-web',
  'package-name',  // Add here
  // ...
]

Web-Only Dependencies

cd apps/next
yarn add package-name
cd ../..
yarn

Native-Only Dependencies

cd apps/expo
yarn add package-name
cd ../..
yarn

---

Troubleshooting

Common Issues

Issue	Solution
Module not found	Run yarn clean && yarn
Metro bundler cache	Run yarn native --clear
Next.js cache	Delete .next folder and rebuild
