DRAFT port to ClojureScript backed by DataScript#58
Open
Conversation
This plan outlines the translation of EACL from Clojure/Datomic to ClojureScript/DataScript for browser demos and edge nodes. Key sections: - Architecture comparison (Datomic vs DataScript) - Technical challenges and solutions (index-range, tuple attrs, lazy seqs) - DataScript schema translation with composite key strategy - 6-phase implementation timeline - Module structure for shared .cljc code - Testing and cross-validation strategy - Performance considerations for browser environments Awaiting approval before implementation begins. https://claude.ai/code/session_01BJ1LJh2FzYBG3bXYYRakum

After checking DataScript's actual tests, confirmed that d/index-range is fully supported with the same API as Datomic. This significantly simplifies the port. Updated sections: - 3.1: Now documents d/index-range as supported ✅ - 8: Revised index strategy - main challenge is tuple attrs, not range scans - Architecture diagrams: Updated to reflect d/index-range works - Phase 2-3: Removed references to custom workarounds The only real challenge is manually computing composite keys since DataScript doesn't support :db/tupleAttrs auto-computation. https://claude.ai/code/session_01BJ1LJh2FzYBG3bXYYRakum
After checking DataScript's actual documentation, confirmed that :db/tupleAttrs is fully supported with auto-computation of composite values - same as Datomic. This means the port is even simpler: - Schema can be translated with minor syntax changes - No manual composite key computation needed - Transaction builders work unchanged - d/index-range works on auto-computed tuples Updated sections: - 3.2: Now documents tupleAttrs as supported ✅ - 4.2: Proper DataScript schema using tupleAttrs - 4.3: Schema conversion function - 8: Simplified index strategy (direct port) - Phase 2: Removed manual key helpers https://claude.ai/code/session_01BJ1LJh2FzYBG3bXYYRakum

Summary
This PR adds a comprehensive implementation plan for porting EACL from Clojure/Datomic to ClojureScript/DataScript. The plan enables running EACL in browsers for demos and edge nodes while maintaining 1-for-1 API compatibility with the existing Datomic implementation.
