Bundle Optimization

Achievement: 61 KB compressed (10× under 700 KB grant requirement)

Modular exports for optimal tree-shaking:

@s5-dev/s5js - Full bundle (61 KB)
@s5-dev/s5js/core - Core only (60 KB)
@s5-dev/s5js/media - Media standalone (10 KB)
@s5-dev/s5js/advanced - Core + CID utilities (61 KB)

Quality Validation

✅ 437 tests passing across 30 test files
✅ Real S5 portal integration validated (s5.vup.cx)
✅ Browser compatibility confirmed (Chrome, Firefox, Safari)
✅ TypeScript compilation clean
✅ Bundle size: 61.12 KB (638.88 KB under budget)

Breaking Changes

Directory format: Uses DirV1 CBOR (not compatible with old MessagePack format)
Node.js requirement: v20+ (for native fetch API support)
Path-based API: New primary interface (legacy CID-based API still available)

Installation & Usage

Installation

npm install @s5-dev/s5js

Basic Usage

import { S5 } from '@s5-dev/s5js';

const s5 = await S5.create({ initialPeers: [...] });
await s5.recoverIdentityFromSeedPhrase(seedPhrase);
await s5.fs.ensureIdentityInitialized();

// Path-based API
await s5.fs.put('home/documents/file.txt', 'content');
const data = await s5.fs.get('home/documents/file.txt');

// List directory
for await (const item of s5.fs.list('home/documents')) {
  console.log(`${item.type}: ${item.name}`);
}

The s5/advanced export was missing critical classes (DirectoryWalker, BatchOperations, identity classes), making it incorrectly smaller than s5/core. Now properly re-exports all core functionality plus advanced CID operations. Bundle sizes (brotli): - Core: 59.58 KB (baseline) - Advanced: 60.60 KB (now correctly includes core + CID utils) - Full: 60.12 KB (all features) Fixes issue where users had to import from both s5/core and s5/advanced. Advanced users can now import everything from a single entry point.

Two related fixes to ensure all export bundles are complete and correctly sized: 1. s5/advanced: Now properly re-exports all core functionality (S5, FS5, DirectoryWalker, BatchOperations) plus advanced CID operations. Previously missing core classes, making it incorrectly smaller than s5/core. 2. s5 (main): Now includes FS5Advanced and CID utilities (formatCID, parseCID, verifyCID, cidToString) for truly complete "full" bundle. Previously missing advanced features. Bundle sizes (brotli): - Core: 59.58 KB (baseline - fs operations only) - Advanced: 60.60 KB (core + CID utils) - Full: 61.14 KB (core + media + CID utils - complete) All bundles remain well under 700 KB grant requirement (638.86 KB margin). Fixes: Users can now import all features from a single entry point, and bundle sizes follow logical hierarchy (Core < Advanced < Full).

Update package metadata for beta publication: - Package name: @julesl23/s5js (scoped to avoid name conflict) - Version: 0.9.0-beta - Enhanced description with feature summary - Repository URL points to julesl23/s5.js fork - Added Jules Lai to contributors - Expanded keywords for npm discoverability

Use globalThis.fetch (available in Node.js 18+ and browsers) instead of undici to ensure webpack/browser bundlers work correctly. Version: 0.9.0-beta.1

Created complete mdBook documentation structure for integration into https://docs.sfive.net/ as Section 8: SDKs & Libraries. Documentation includes: - 13 files in s5-docs-sdk-js/ folder ready for Redsolver - 9 comprehensive SDK pages (installation, quick-start, path-api, media, advanced-cid, performance, utilities, encryption, api-reference) - book.toml configuration for mdBook - SUMMARY.md table of contents - Integration instructions in README.md Package naming: - Uses official @s5-dev/s5js throughout all examples - Includes beta testing note explaining current @julesl23/s5js@beta package - Future-proof for upstream merge Style matches S5 docs conventions: - Concise technical tone - TypeScript code examples - Tables for structured data - Progressive complexity (basic to advanced) Deliverable 2 (Documentation Site Update): Ready for submission

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. Beta testers get clear instructions for current temporary package.

Fixed remaining references to use official s5-dev repository: - book.toml: Updated git-repository-url and edit-url-template - index.md: Fixed GitHub link text to show s5-dev/s5.js - README.md: Fixed GitHub link text to show s5-dev/s5.js All 15 GitHub references now correctly point to github.com/s5-dev/s5.js Documentation is now fully ready for integration into docs.sfive.net

Milestone 8: Complete Enhanced s5.js Grant Implementation

Document all Enhanced s5.js grant deliverables (Milestones 1-8): - Path-based API and CBOR/DirV1 implementation - HAMT sharding for large directories - Directory utilities (walker, batch operations) - Media processing with WASM/Canvas - Advanced CID API - Bundle optimization (61 KB - 10x under budget) - Testing and validation (437 tests passing) - Documentation and upstream preparation

Restore hybrid approach for HTTP client: - Node.js: use undici for S5 portal compatibility - Browser: use globalThis for webpack/bundler compatibility The previous change to globalThis.fetch broke portal uploads in Node.js because native FormData formats multipart/form-data differently than undici, causing HTTP 400 errors from s5.vup.cx. This fix maintains both portal compatibility and browser bundling support.

Adds missing await to registry.ts put() method when writing to database. Without this, fs.get() could return null immediately after fs.put() because the registry entry might not be persisted yet. Fixes issue where subsequent get operations (using 250ms delay path) fail while database write completes asynchronously in real IndexedDB environments. This bug was masked in tests using fake-indexeddb (synchronous) but affects production usage with async storage backends.

* chore: reduce verbose console logging - Remove 18 verbose server connection/startup logs - Remove 3 registry cache debug logs - Remove seed phrase console.log (security risk) - Remove commented debug statement in p2p.ts Reduces active console statements from 51 to 28 (45% reduction). Fixes Chrome DevTools crashes when filtering [Enhanced S5.js] logs.
