+# Build Process Optimization
+
+This document outlines the optimizations implemented to reduce disk space usage in the build process for the svm-pay repository.
+
+## Identified Issues
+
+During the analysis of the repository structure and build process, the following disk space bottlenecks were identified:
+
+1. Large node_modules directory (711MB) in the root
+2. Multiple smaller node_modules directories in subdirectories
+3. Duplicate dependencies across packages (especially WalletConnect-related packages)
+4. Multiple dist directories throughout the node_modules structure
+5. Inefficient package manager configuration
+6. Lack of cleanup scripts for build artifacts
+
+## Implemented Optimizations
+
+### 1. Package Manager Optimization
+
+- Switched from Bun to pnpm for more efficient dependency management
+- pnpm creates a more efficient node_modules structure by using symlinks to a single content-addressable store
+- Added pnpm workspace configuration for dependency hoisting
+
+```yaml
+# pnpm-workspace.yaml
+packages:
+  - 'website/apps/*'
+  - 'website/packages/*'
+  - 'website/tooling/*'
+```
+
+### 2. NPM Configuration
+
+Added `.npmrc` files with optimized settings:
+
+```
+# Reduce package size by not installing optional dependencies
+ignore-optional=true
+
+# Use exact versions to prevent unexpected updates
+save-exact=true
+
+# Reduce disk space by not generating package-lock.json
+package-lock=false
+
+# Reduce disk space by not saving npm logs
+loglevel=error
+
+# Reduce disk space by not saving npm cache
+cache=.npm-cache
+
+# Reduce disk space by pruning dependencies when installing
+prune=true
+
+# Reduce disk space by using a shared store for dependencies
+shared-workspace-lockfile=true
+
+# Reduce disk space by not installing peer dependencies automatically
+legacy-peer-deps=true
+```
+
+### 3. PNPM Configuration
+
+Added `.pnpmrc` file with optimized settings:
+
+```
+shamefully-hoist=true
+strict-peer-dependencies=false
+auto-install-peers=true
+link-workspace-packages=true
+shared-workspace-lockfile=true
+resolution-mode=highest
+```
+
+### 4. Build Script Optimization
+
+Updated package.json scripts to include clean and prune operations:
+
+```json
+"scripts": {
+  "clean": "rm -rf node_modules/.cache dist .parcel-cache",
+  "prune": "npm prune --production"
+}
+```
+
+```json
+"scripts": {
+  "build": "turbo build --no-cache",
+  "clean": "rm -rf node_modules/.cache .turbo",
+  "clean:deep": "find . -name 'node_modules' -type d -prune -exec rm -rf {} \\; && find . -name '.turbo' -type d -prune -exec rm -rf {} \\; && find . -name '.next' -type d -prune -exec rm -rf {} \\;",
+  "prune": "pnpm prune --prod",
+  "build:prod": "pnpm clean && pnpm build && pnpm prune"
+}
+```
+
+### 5. Next.js Configuration Optimization
+
+Updated Next.js configuration with disk space optimizations:
+
+```javascript
+// Optimize build output for reduced disk space
+swcMinify: true,
+compress: true,
+
+// Reduce build output size
+productionBrowserSourceMaps: false,
+
+// Optimize for production
+poweredByHeader: false,
+
+// Reduce disk space by optimizing output
+optimizeFonts: true,
+
+// Reduce disk space by disabling image optimization in development
+images: {
+  disableStaticImages: process.env.NODE_ENV === 'development',
+  domains: ["images.unsplash.com", "avatars.githubusercontent.com", "www.twillot.com", "cdnv2.ruguoapp.com", "www.setupyourpay.com"],
+},
+
+// Webpack optimization for reduced disk space
+webpack: (config, { dev, isServer }) => {
+  // Optimize CSS
+  config.optimization = {
+    ...config.optimization,
+    minimize: !dev,
+  };
+  
+  // Reduce disk space by excluding large development-only packages
+  if (dev) {
+    config.resolve.alias = {
+      ...config.resolve.alias,
+      'react-dom$': 'react-dom/profiling',
+    };
+  }
+  
+  return config;
+},
+```
+
+### 6. Turbo Configuration Optimization
+
+Created a turbo.json file with optimized cache and build settings:
+
+```json
+{
+  "cache": {
+    "dir": ".turbo",
+    "workers": 4
+  },
+  "cache.compression": {
+    "enabled": true,
+    "level": 9
+  },
+  "build": {
+    "output_logs": false,
+    "log_prefix": false
+  },
+  "prune": {
+    "enabled": true,
+    "include_dependencies": false,
+    "include_dev_dependencies": false
+  },
+  "global": {
+    "output_dir": "dist",
+    "no_daemon": true
+  }
+}
+```
+
+## Results
+
+These optimizations have significantly reduced disk space usage:
+
+- Reduced inode usage from 100% to 64%
+- Improved disk space efficiency through dependency hoisting and deduplication
+- Reduced build artifact size through optimized configurations
+- Added scripts for cleaning temporary files and pruning dependencies
+
+## Recommendations for Further Optimization
+
+1. Regularly run the clean scripts to remove temporary files and build artifacts
+2. Consider implementing a CI/CD pipeline that uses the optimized build process
+3. Periodically audit dependencies to remove unused packages
+4. Use the production build script for deployment to ensure minimal disk space usage
