Scripts only stop s5js-prod, never dev containers - Proper health checks and monitoring Tested: Seed persistence working, same identity across restarts --- Dockerfile.prod | 49 +++++++++++ Dockerfile.s5js-prod | 27 ++++++ docker-compose.prod.yml | 35 ++++++++ docs/DOCKER_PRODUCTION.md | 179 ++++++++++++++++++++++++++++++++++++++ docs/DOCKER_SCRIPTS.md | 176 +++++++++++++++++++++++++++++++++++++ server-real-s5.js | 16 +++- start-s5js-prod.sh | 151 ++++++++++++++++++++++++++++++++ stop-s5js-prod.sh | 82 +++++++++++++++++ 8 files changed, 714 insertions(+), 1 deletion(-) create mode 100644 Dockerfile.prod create mode 100644 Dockerfile.s5js-prod create mode 100644 docker-compose.prod.yml create mode 100644 docs/DOCKER_PRODUCTION.md create mode 100644 docs/DOCKER_SCRIPTS.md create mode 100644 start-s5js-prod.sh create mode 100644 stop-s5js-prod.sh diff --git a/Dockerfile.prod b/Dockerfile.prod new file mode 100644 index 0000000..a18bd7d --- /dev/null +++ b/Dockerfile.prod @@ -0,0 +1,49 @@ +# Production Dockerfile for S5.js Server +FROM node:20-alpine + +# Install required system dependencies +RUN apk add --no-cache \ + python3 \ + make \ + g++ \ + && rm -rf /var/cache/apk/* + +# Create app directory +WORKDIR /app + +# Copy package files +COPY package*.json ./ + +# Install production dependencies only +RUN npm ci --only=production && \ + npm cache clean --force + +# Copy only necessary production files +COPY dist/ ./dist/ +COPY server-real-s5.js ./ + +# Create a non-root user to run the app +RUN addgroup -g 1001 -S nodejs && \ + adduser -S nodejs -u 1001 + +# Create directory for seed file mount +RUN mkdir -p /home/nodejs/.s5 && \ + chown -R nodejs:nodejs /home/nodejs/.s5 + +# Switch to non-root user +USER nodejs + +# Expose the S5 server port +EXPOSE 5522 + +# Health check +HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \ + CMD node -e "require('http').get('http://localhost:5522/health', (r) => process.exit(r.statusCode === 200 ? 0 : 1))" + +# Default to real mode, can be overridden +ENV S5_MODE=real +ENV PORT=5522 +ENV NODE_ENV=production + +# Start the server +CMD ["node", "server-real-s5.js"] \ No newline at end of file diff --git a/Dockerfile.s5js-prod b/Dockerfile.s5js-prod new file mode 100644 index 0000000..5ad1bf2 --- /dev/null +++ b/Dockerfile.s5js-prod @@ -0,0 +1,27 @@ +FROM node:20-alpine + +# Install minimal dependencies +RUN apk add --no-cache curl + +# Create app directory +WORKDIR /app + +# Copy necessary files +COPY server-real-s5.js . +COPY package.json . +COPY package-lock.json . + +# Copy source directory (contains the actual S5 implementation) +COPY src ./src + +# Copy node_modules +COPY node_modules ./node_modules + +# Create directory for seed file +RUN mkdir -p /app/config + +# Expose port +EXPOSE 5522 + +# Run server +CMD ["node", "server-real-s5.js"] diff --git a/docker-compose.prod.yml b/docker-compose.prod.yml new file mode 100644 index 0000000..8d10ef2 --- /dev/null +++ b/docker-compose.prod.yml @@ -0,0 +1,35 @@ +version: '3.8' + +services: + s5js-server: + build: + context: . + dockerfile: Dockerfile.prod + container_name: s5js-prod + image: s5js-server:prod + ports: + -

⚠️ Simulated Demo

+

+ This is a simulated demonstration of code-splitting capabilities. + In a production environment with proper bundler configuration (Webpack, Rollup, Vite), + the actual modules would be loaded dynamically. This demo simulates the loading behavior + and shows the expected bundle sizes and performance benefits. +

+

+ The actual MediaProcessor API is already available. Test it with an image: +

+ + +
+ + +
+

+ 💻 + Implementation Example +

+ 
+// Regular import (loads everything)
+import { S5, MediaProcessor } from 's5.js';
+
+// Code-split imports (recommended)
+import { S5 } from 's5.js/core';
+
+// Lazy load media when needed
+const loadMedia = async () => {
+  const { MediaProcessor } = await import('s5.js/media');
+  return MediaProcessor;
+};
+
+// Usage
+button.onclick = async () => {
+  const MediaProcessor = await loadMedia();
+  await MediaProcessor.initialize();
+  // Now ready for image processing
+};
+
+ +
+ Note: Code-splitting reduces initial bundle size by ~27% when media features aren't needed immediately. + Media processing adds only ~79KB (19KB gzipped) when loaded on-demand. +

📦 Code-Splitting Demonstration

-

⚠️ Simulated Demo

+

💡 Demo Information

- This is a simulated demonstration of code-splitting capabilities. + This demo uses real S5.js code with real MediaProcessor functionality. + All image processing, WASM initialization, and metadata extraction are fully functional. + Only the bundle loading animation is simulated for demonstration purposes (the bundles are pre-loaded in this HTML page). In a production environment with proper bundler configuration (Webpack, Rollup, Vite), - the actual modules would be loaded dynamically. This demo simulates the loading behavior - and shows the expected bundle sizes and performance benefits. + the code-splitting would happen automatically at build time.

This means: + +- ✅ **Convenience**: No separate key management needed +- ✅ **Automatic**: Decryption works transparently with directory access +- ⚠️ **Access Control**: Anyone with directory read access can decrypt files +- ⚠️ **Key Exposure**: Keys are visible to anyone who can read the directory + +**For maximum security**, consider: + +1. **User-Provided Keys**: Supply your own keys and manage them separately + + ```typescript + const userKey = deriveFromPassword(password); // Keep key separate + await s5.fs.put(path, data, { encryption: { key: userKey } }); + ``` + +2. **Directory-Level Encryption**: Encrypt the entire directory with a separate key +3. **Key Derivation**: Derive keys from user credentials that aren't stored + +#### Best Practices + +1. **Use Auto-Generated Keys** for convenience when directory access control is sufficient +2. **Use Custom Keys** when you need encryption independent of directory access +3. **Never commit encryption keys** to source control +4. **Rotate keys periodically** for sensitive data +5. **Use strong key derivation** (e.g., PBKDF2, Argon2) if deriving from passwords +6. **Consider the threat model**: Encryption protects against network observers and storage providers, but not against directory access + +#### What Encryption Protects + +- ✅ **Content confidentiality**: File contents cannot be read without the key +- ✅ **Content integrity**: Modifications are detected (authenticated encryption) +- ✅ **Network privacy**: Data is encrypted in transit and at rest +- ❌ **File names**: Directory entry names are NOT encrypted +- ❌ **Metadata**: File sizes, timestamps, counts remain visible +- ❌ **Access patterns**: Who accesses which files can still be observed + +### Encryption Metadata + +Encrypted files store metadata in the FileRef's `extra` field: + +```typescript +// Example FileRef for encrypted file +{ + hash: Uint8Array, // Encrypted blob hash + size: 12345, // Original plaintext size + media_type: "text/plain", + timestamp: 1705432100, + extra: Map([ + ['encryption', { + algorithm: 'xchacha20-poly1305', + key: [123, 45, 67, ...], // 32-byte encryption key + plaintextHash: [...] // Original plaintext hash + }] + ]) +} +``` + +You can check if a file is encrypted via metadata: + +```typescript +const metadata = await s5.fs.getMetadata("home/secrets/file.txt"); +if (metadata.custom?.encryption) { + console.log("File is encrypted"); + console.log("Algorithm:", metadata.custom.encryption.algorithm); +} +``` + +### Performance Impact + +Encryption has minimal performance impact: + +- **Encryption overhead**: ~1-2% for XChaCha20-Poly1305 (very fast) +- **Chunk processing**: Parallel chunk encryption for large files +- **Memory usage**: Chunks processed incrementally (constant memory) +- **Network**: Same upload/download sizes (minimal encryption expansion) + +**Benchmarks** (approximate): + +- Small files (<1 MB): Negligible overhead (~5-10ms) +- Large files (>10 MB): ~1-2% slower than unencrypted +- Very large files (>100 MB): Chunked processing maintains performance + +### Limitations + +- **Algorithm**: Currently only XChaCha20-Poly1305 is supported +- **Key Storage**: Keys are stored in directory metadata (see Security Considerations) +- **Migration**: Cannot change encryption key for existing files (must re-upload) +- **Partial Decryption**: Must decrypt entire file (no partial chunk reads) +- **Compression**: No automatic compression before encryption (plan ahead) + ## Types and Interfaces ### PutOptions @@ -389,6 +676,11 @@ for await (const item of s5.fs.list("home/docs", { interface PutOptions { mediaType?: string;

ProgressiveImageLoader with automatic format detection - Format-specific implementations for JPEG, PNG, and WebP - Abstract ProgressiveImage base class with concrete implementations - Layer-by-layer access for progressive rendering Progressive JPEG: - Multiple quality scans (configurable, default: 3) - Custom quality levels per scan (default: [20, 50, 85]) - Sequential scan numbering with baseline layer - Efficient layer management for web streaming Progressive PNG: - Adam7 interlacing support (enabled by default) - Non-interlaced option available - Single-layer native PNG interlacing - Full quality preservation Progressive WebP: - Multiple quality level layers (default: [30, 60, 90]) - Configurable quality progression - Highest quality layer for final output Implementation: - Added ProgressiveLoadingOptions and ProgressiveLayer types - Format detection from magic bytes (JPEG, PNG, WebP) -

media extensions follow the path-based API design: + +- **Paths are identifiers**: Files are accessed by filesystem paths, not content hashes +- **Content addressing abstracted**: The underlying S5 content-addressed storage is an implementation detail +- **Simple, familiar interface**: Works like traditional file systems +- **No CID exposure**: Content identifiers (CIDs) are not exposed in the public API + +This design makes the API: +- Easier to use for web developers +- Consistent with file system semantics +- Independent of underlying storage implementation + +For advanced use cases requiring content addressing, access the internal `FileRef` structures through the S5Node API. + ## Performance Considerations - **Directory Caching**: Directory metadata is cached during path

Create shared node-polyfills.js for Node.js browser API mocking - Add Image constructor with real dimension parsing (PNG, JPEG, GIF, BMP, WebP) - Override URL.createObjectURL to track blobs for dimension extraction - Add document.createElement mock for Canvas API support - Update all 4 media demos to import polyfills Image dimension parsing: - PNG: Extract from IHDR chunk at offset 16 (width) and 20 (height) - JPEG: Scan for SOF0/SOF2 markers containing frame dimensions - GIF: Read dimensions at offset 6-9 (little-endian) - BMP: Read dimensions at offset 18-21 (little-endian) - WebP: Parse VP8/VP8L formats from RIFF structure Results: - 5/6 test images now show correct dimensions (1×1) -

charset=UTF-8 Content-Transfer-Encoding: 8bit Updated all package and repository references to use the official S5 organization namespace for future-proof documentation integration into docs.sfive.net. Changes: - GitHub repository: julesl23/s5.js → s5-dev/s5.js (13 occurrences) - npm package: @julesl23/s5js → @s5-dev/s5js (already done) - Added beta testing note explaining current @julesl23/s5js@beta package Accuracy corrections: - Changed description to "alternative implementation of S5 v1 specs" - Added s5-rs as existing Rust implementation (not "coming soon") - Removed speculative "Future SDKs" section - Corrected SDK attribution (not all community work) All documentation now uses official namespace for after PR merge.

Organize docs into logical subfolders (development/, testing/, grant/) - Keep essential user-facing docs in root (API.md, BENCHMARKS.md, etc.) - Remove server/deployment infrastructure (not part of SDK) - Remove personal integration files (Fabstir, webxdc examples) - Clean up testing scripts and obsolete documentation This prepares the repository for upstream PR by focusing on SDK code, tests, and user-facing documentation. --- README-FABSTIR-INTEGRATION.md | 33 -

console.log(`Deleting: ${progress.currentPath}`); - } -}); -``` - -### Copy Directory - -```typescript -async copyDirectory( - sourcePath: string, - destPath: string, - options?: BatchOptions -): Promise -``` - -**Options:** -```typescript -interface BatchOptions { - recursive?: boolean; - onProgress?: (progress: BatchProgress) => void; - onError?: 'stop' | 'continue' | ((error, path) => 'stop' | 'continue'); -} -``` - -**Example:** - -```typescript -const result = await batch.copyDirectory('home/photos', 'archive/photos-backup', { - recursive: true, - onProgress: (progress) => { - const percent = (progress.processed / progress.total * 100).toFixed(1); - console.log(`${percent}% - ${progress.currentPath}`); - }, - onError: (error, path) => { - console.error(`Failed to copy ${path}: ${error.message}`); - return 'continue'; // Skip errors and continue - } -}); - -console.log(`Copied ${result.success} files, ${result.failed} failed`); -``` - -### Delete Directory - -```typescript -async deleteDirectory( - path: string, - options?: BatchOptions -): Promise -``` - -**Example:** - -```typescript -const result = await batch.deleteDirectory('home/cache', { - recursive: true, - onProgress: (progress) => { - console.log(`Deleting: ${progress.currentPath}`); - } -}); - -if (result.failed > 0) { - console.error('Some files failed to delete:'); - result.errors.forEach(e => console.error(` ${e.path}: ${e.error.message}`)); -} -``` - -## Progress Tracking - -All batch operations provide detailed progress information: - -```typescript -interface BatchProgress { - processed: number; // Number of items processed - total: number; // Total items to process - currentPath: string; // Currently processing path - success: number; // Successfully processed - failed: number; // Failed items -} - -interface BatchResult { - success: number; - failed: number; - errors: Array<{ path: string; error: Error }>; -} -``` - -## Complete Examples - -### Backup with Progress Bar - -```typescript -async function backupWithProgress(source: string, dest: string) { - const batch = new BatchOperations(s5.fs); - const startTime = Date.now(); - - console.log(`Starting backup of ${source}...`); - - const result = await batch.copyDirectory(source, dest, { - recursive: true, - onProgress: (progress) => { - const percent = (progress.processed / progress.total * 100).toFixed(1); - process.stdout.write(`\r[${percent}%] ${progress.currentPath.padEnd(50)}`); - }, - onError: 'continue' - }); - - const duration = ((Date.now() - startTime) / 1000).toFixed(1); - - console.log(`\n✅ Backup complete in ${duration}s`); - console.log(` Success: ${result.success}, Failed: ${result.failed}`); - - if (result.failed > 0) { - // Save error log - const errorLog = result.errors - .map(e => `${e.path}: ${e.error.message}`) - .join('\n'); - await s5.fs.put(`${dest}-errors.log`, errorLog); - console.log(` Error log: ${dest}-errors.log`); - } -} -``` - -### Clean Temporary Files - -```typescript -async function cleanupTempFiles(basePath: string) { - const walker = new DirectoryWalker(s5.fs); - let cleaned = 0; - - for await (const entry of walker.walk(basePath, { recursive: true })) { - if (entry.type === 'file' && entry.name.endsWith('.tmp')) { - const deleted = await s5.fs.delete(entry.path); - if (deleted) { - cleaned++; - console.log(`Deleted: ${entry.path}`); - } - } - } - - console.log(`Cleaned ${cleaned} temporary files`); -} -``` - -### Find Large Files - -```typescript -async function findLargeFiles(basePath: string, minSize: number) { - const walker = new DirectoryWalker(s5.fs); - const largeFiles = []; - - for await (const entry of walker.walk(basePath, { - recursive: true, - filter: (e) => e.type === 'file' && e.size > minSize - })) { - largeFiles.push({ - path: entry.path, - size: entry.size, - sizeInMB: (entry.size / 1024 / 1024).toFixed(2) - }); - } - - // Sort by size - largeFiles.sort((a, b) => b.size - a.size); - - console.log(`Found ${largeFiles.length} files larger than ${minSize} bytes:`); - largeFiles.slice(0, 10).forEach(f => { - console.log(` ${f.sizeInMB} MB - ${f.path}`); - }); - - return largeFiles; -} -``` - -### Synchronize Directories - -```typescript -async function syncDirectories(source: string, dest: string) { - const walker = new DirectoryWalker(s5.fs); - const batch = new BatchOperations(s5.fs); - - // Get source files - const sourceFiles = new Map(); - for await (const entry of walker.walk(source, { recursive: true })) { - if (entry.type === 'file') { - sourceFiles.set(entry.name, entry); - } - } - - // Get destination files - const destFiles = new Map(); - for await (const entry of walker.walk(dest, { recursive: true })) { - if (entry.type === 'file') { - destFiles.set(entry.name, entry); - } - } - - // Copy new/modified files - let copied = 0; - for (const [name, sourceEntry] of sourceFiles) { - const destEntry = destFiles.get(name); - if (!destEntry || sourceEntry.timestamp > destEntry.timestamp) { - const data = await s5.fs.get(sourceEntry.path); - await s5.fs.put(`${dest}/${name}`, data); - copied++; - console.log(`Synced: ${name}`); - } - } - - // Delete removed files - let deleted = 0; - for (const [name, destEntry] of destFiles) { - if (!sourceFiles.has(name)) { - await s5.fs.delete(destEntry.path); - deleted++; - console.log(`Removed: ${name}`); - } - } - - console.log(`Sync complete: ${copied} copied, ${deleted} removed`); -} -``` - -## Error Handling - -```typescript -// Stop on first error -const result1 = await batch.copyDirectory('home/source', 'archive/dest', { - onError: 'stop' -}); - -// Continue on errors -const result2 = await batch.copyDirectory('home/source', 'archive/dest', { - onError: 'continue' -}); - -// Custom error handling -const result3 = await batch.copyDirectory('home/source', 'archive/dest', { - onError: (error, path) => { - if (error.message.includes('permission')) { - console.log(`Skipping protected file: ${path}`); - return 'continue'; - } - return 'stop'; - } -}); -``` - -## Performance Tips - -1. **Use filters early**: Filter in `walk()` options instead of checking each entry -2. **Batch operations**: Group related operations together -3. **Progress callbacks**: Don't perform heavy operations in progress callbacks -4. **Error handling**: Use 'continue' for non-critical errors to avoid interruption - -## TypeScript Types - -```typescript -interface WalkEntry { - path: string; - name: string; - type: 'file' | 'directory'; - size?: number; - mediaType?: string; - timestamp?: number; -} - -interface WalkOptions { - recursive?: boolean; - maxDepth?: number; - filter?: (entry: WalkEntry) => boolean; -} - -interface BatchOptions { - recursive?: boolean; - onProgress?: (progress: BatchProgress) => void; - onError?: 'stop' | 'continue' | ((error: Error, path: string) => 'stop' | 'continue'); -} -``` -
