Practices + +### 1. Semantic Versioning + +Use semantic versioning (MAJOR.MINOR.PATCH): + +```python +# MAJOR: Breaking changes +"1.0.0" -> "2.0.0" # Schema completely changed + +# MINOR: Backward-compatible additions +"2.0.0" -> "2.1.0" # Added optional fields + +# PATCH: Bug fixes, no schema change +"2.1.0" -> "2.1.1" # Fixed data validation +``` + +### 2. Always Version Your Data + +```python +from zon import embed_version + +# Do this +data = fetch_data() +versioned = embed_version(data, "1.0.0", "my-schema") +save_data(versioned) + +# Not this +save_data(data) # No version info! +``` + +### 3. Test Migrations + +```python +import unittest +from zon import ZonMigrationManager + +class TestMigrations(unittest.TestCase): + def setUp(self): + self.manager = ZonMigrationManager() + setup_migrations(self.manager) + + def test_v1_to_v2(self): + v1_data = {"users": [{"id": 1, "name": "Alice"}]} + v2_data = self.manager.migrate(v1_data, "1.0.0", "2.0.0") + + # Verify email was added + self.assertIn('email', v2_data['users'][0]) + + def test_chained_migration(self): + v1_data = {"users": [{"id": 1, "name": "Alice"}]} + v3_data = self.manager.migrate(v1_data, "1.0.0", "3.0.0") + + # Verify all transformations + self.assertIn('email', v3_data['users'][0]) + self.assertIn('roles', v3_data['users'][0]) +``` + +### 4. Handle Missing Migrations + +```python +from zon import ZonMigrationManager + +manager = ZonMigrationManager() + +try: + migrated = manager.migrate(data, "1.0.0", "5.0.0") +except ValueError as e: + if "No migration path" in str(e): + # Handle missing migration + logger.error(f"Cannot migrate from 1.0.0 to 5.0.0") + # Fallback strategy + data = reset_to_latest_schema(data) + else: + raise +``` + +### 5.
