Package features: - Composition pattern wrapping SqlDriver for query compilation - Custom Knex client adapter for PGlite WASM - IndexedDB/OPFS/Memory persistence backends with auto-fallback - Environment detection with ObjectQLError for missing WASM - PostgreSQL-specific features: JSONB operators, full-text search - Full transaction support with savepoints and isolation levels - Comprehensive test suite (23 tests passing) Implementation follows same patterns as @objectql/driver-sqlite-wasm: - Library-agnostic public API (references "PostgreSQL WASM", not "PGlite") - ~3MB bundle size documented for informed choice vs SQLite WASM - No Node.js support (browser-only driver) - Lazy WASM module loading Files created: - src/index.ts - Main PgWasmDriver class - src/environment.ts - Environment detection utilities - src/wasm-loader.ts - PGlite WASM lazy loader - src/knex-adapter.ts - Custom Knex client for PGlite - test/index.test.ts - Comprehensive unit tests - README.md - Complete documentation - package.json, tsconfig.json - Package configuration All builds and tests passing.

It evaluates guards, executes actions, and either allows or denies state transitions—without modifying SQL generation. + +### Key Features + +- **XState-Compatible**: Follows XState state machine patterns +- **Guard Conditions**: Control which transitions are allowed +- **Entry/Exit Actions**: Execute side effects during transitions +- **Compound States**: Hierarchical state nesting with automatic resolution +- **Audit Trail**: Optional persistence of all state transitions +- **Type-Safe**: Full TypeScript support with protocol-derived types + +### Architecture + +``` +┌──────────────────────────────┐ +│ plugin-workflow │ ← beforeUpdate hook: evaluate guards, execute actions +│ (State Machine Executor) │ +├──────────────────────────────┤ +│ plugin-validator │ ← field/cross-field/uniqueness validation +├──────────────────────────────┤ +│ QueryService → QueryAST │ ← Core: abstract query building +├──────────────────────────────┤ +│ Driver → Knex → SQL │ ← Driver: SQL generation (UNTOUCHED) +└──────────────────────────────┘ +``` + +## Basic State Machine + +Define a simple state machine in your object metadata: + +```yaml +# project.object.yml +name: project +fields: + status: + type: select + options: [draft, active, done] + default: draft + +stateMachine: + initial: draft + states: + draft: + on: + submit: + target: active + active: + on: + complete: + target: done + done: + type: final +``` + +### TypeScript Configuration + +```typescript +import { ObjectConfig } from '@objectql/types'; + +const projectConfig: ObjectConfig = { + name: 'project', + fields: { + status: { + type: 'select', + options: ['draft', 'active', 'done'], + default: 'draft', + }, + }, + stateMachine: { + initial: 'draft', + states: { + draft: { + on: { + submit: { target: 'active' }, + }, + }, + active: { + on: { + complete: { target: 'done' }, + }, + }, + done: { + type: 'final', + }, + }, + }, +}; +``` + +### What Happens + +1.

+ const decoded = await verifyToken(token); + return decoded.organizationId; + }, +}); +``` + +## Exempt Objects + +Some objects may need to be accessible across tenants (e.g., users, tenants): + +```typescript +new MultiTenancyPlugin({ + exemptObjects: ['users', 'tenants', 'global_settings'], +}); +``` + +## Schema Isolation Modes + +### None (Default) + +All tenants share the same table with `tenant_id` column: + +```sql +CREATE TABLE accounts ( + id SERIAL PRIMARY KEY, + tenant_id VARCHAR(255) NOT NULL, + name VARCHAR(255), + INDEX idx_tenant (tenant_id) +); +``` + +### Table Prefix + +Each tenant gets separate tables with a prefix: + +```sql +CREATE TABLE accounts_tenant_1 (...); +CREATE TABLE accounts_tenant_2 (...); +``` + +### Separate Schema + +Each tenant gets a separate database schema: + +```sql +CREATE SCHEMA tenant_1; +CREATE TABLE tenant_1.accounts (...); + +CREATE SCHEMA tenant_2; +CREATE TABLE tenant_2.accounts (...); +``` + +## Audit Logging + +Access the audit logs to track tenant operations: + +```typescript +const plugin = new MultiTenancyPlugin({ enableAudit: true });
