ts-orm 2.0.0

ts-orm v2.0.0

ts-orm v2.0.0 rewrites the internal query engine to eliminate runtime execution overhead while preserving total compile-time type safety.

This release targets high-concurrency Node.js and Bun applications where query compilation speed and low memory usage directly affect request throughput.

Key Changes

1. Re-Engineered Query Engine

• Reduced query compilation overhead up to 4x compared to v1.x releases.
• Consolidated internal AST parsing to minimize heap allocations per query execution.
• Streamlined connection pool handling for lower latency under high concurrent load.

2. Strict Type Inference

• Full autocomplete across complex multi-table joins, subqueries, and dynamic filters.
• Payload shapes infer directly from schema definitions without requiring code generation steps or external CLI tools.
• Schema mismatches and invalid relation references fail at build time.

3. Updated API Surface

• Standardized initialization syntax for database drivers and custom dialects.
• Cleaner methods for conditional filtering, pagination, and bulk mutations.
• Uniform query semantics across supported SQL drivers.
