json-schema-to-zod + Zod v4 Compatibility Test

Verifies that @composio/json-schema-to-zod works correctly with zod@4.

Why This Exists

The @composio/json-schema-to-zod package must support both Zod v3 and v4. This suite ensures:

Test	Description
Basic string schema	Converts `{ type: 'string' }` and validates
Object schema	Required fields, nested properties, validation constraints
Array schema	Typed array items with validation
Email format	Format validation for email strings
Nested schemas	Complex nested objects and arrays
anyOf schemas	Union type conversion
additionalProperties	Strict, passthrough, and typed catchall modes
Complex nested arrays	Arrays of objects with nested arrays
Union with constraints	anyOf with minLength, minimum, and required fields

This test runs directly in Bun (no Docker fixtures). The test file imports @composio/json-schema-to-zod from the monorepo workspace:

typescript

import { jsonSchemaToZod, type JsonSchema } from '@composio/json-schema-to-zod';

Tests use bun:test assertions to verify schema conversion and parsing behavior.

Docker with Node.js versions: current (as specified in .nvmrc).
