RX Data Store

Skill by ara.so — Daily 2026 Skills collection.

RX is an embedded data store for JSON-shaped data. Encode once, then query the encoded document in place — no parsing, no object graph, no GC pressure. Think of it as no-SQL SQLite: unstructured data with database-style random access.

Key benefits:

• O(1) array access, O(log n) object key lookup on encoded data
• Automatic deduplication of values and shared schemas
• Text-safe encoding (copy-paste friendly, no binary tooling needed)
• Minimal heap allocations (~10 vs millions for JSON parsing)
• ~18x compression on real deployment manifests (92 MB → 5.1 MB)

Installation

npm install @creationix/rx        # library
