Description: Summary Adds preliminary implementation of W3C Linked Web Storage (LWS) protocol mode as an optional configuration flag. Status: 🚧 DRAFT - This PR captures the initial infrastructure for LWS support. Not intended for immediate merge - waiting for ecosystem signals (see #87). Changes Config Infrastructure ✅ Added --lws-mode CLI flag ✅ Added JSS_LWS_MODE environment variable support ✅ Added lwsMode config file option ✅ Server displays "LWS Mode: enabled (DRAFT)" in config output Core Implementation ✅ PUT restriction: In LWS mode, PUT returns 404 for non-existent resources with helpful error message suggesting POST ✅ Preserves LDP mode: Default behavior unchanged (PUT creates or updates) ✅ Request decoration: request.lwsMode available to all handlers Testing ✅ Basic LWS test suite (test/lws.test.js) Tests PUT rejection for non-existent resources Tests PUT success for updates Tests POST for creation (already works) Documents key LWS differences Documentation ✅ README section explaining LWS mode with examples ✅ Comparison table (Solid/LDP vs LWS) ✅ Warning about draft status ✅ Links to issue #87 for full context Key Difference Solid/LDP Mode (default): PUT /alice/new.json → 201 Created (creates resource) LWS Mode: PUT /alice/new.json → 404 Not Found (suggests POST instead) POST /alice/ + Slug → 201 Created (required for creation) PUT /alice/existing.json → 204 No Content (updates work) What's NOT Implemented Yet From the full plan in #87, this PR only implements the foundation: ❌ Link header-based container detection (still uses trailing slash) ❌ Linkset metadata endpoints (/resource;linkset) ❌ JSON Merge Patch for metadata ❌ Full test matrix (only basic tests included) These are intentionally deferred until we see ecosystem adoption. Why This PR Exists This PR: Captures the analysis from evaluating LWS PR #37 Proves feasibility - demonstrates LWS mode can coexist with LDP Enables experimentation - developers can test LWS semantics Preserves work - when/if LWS gains traction, we have a foundation Decision Criteria for Merge Recommend merging when: ✅ At least 3 other servers implement LWS protocol ✅ At least 5 client apps use LWS endpoints ✅ W3C Solid CG shows interest in LWS alignment ✅ LWS spec reaches Candidate Recommendation Current status (Jan 2026): Servers: Unknown Clients: Likely zero Spec: Early draft (PR #37 just merged) Testing # Run LWS-specific tests npm test -- test/lws.test.js # Run full suite (LWS tests are isolated) npm test Related Issue: #87 LWS Spec PR: w3c/lws-protocol#37 LWS Repo: https://github.com/w3c/lws-protocol Checklist Config flag infrastructure Basic PUT restriction logic Tests demonstrating behavior README documentation Full container detection (deferred) Linkset endpoints (deferred) Complete test matrix (deferred) Note: Keeping as draft until ecosystem signals warrant merge. Can be rebased/updated as LWS spec evolves.
