CreateOrderInput validates client data and OrderDTO shapes API responses, with inferred TypeScript types exported from packages/types. - Indian Localization Conventions: Built-in patterns for +91 phone numbers, 6-digit PIN codes, GSTIN format, and integer-paise money handling with dual formatted responses. - Environment & Worker Payload Validation: Parse process.env with a strict Zod schema and validate worker job payloads (orders, invoices) before processing. - Use Case: When adding a new API route that accepts order creation requests, use this Skill to generate the input schema, DTO, and inferred types following the established packages/types conventions. ## Quick Start Create a Zod input schema and DTO for a new shipment tracking endpoint following the DropFlow patterns in packages/types.High-intent search queries and answers about installing and using this skill.
Define the schema with z.object(), then export the type using z.infer<typeof SchemaName>. Name both identically, such as CreateOrderInput for both the schema and its inferred type, and export both from packages/types.
Define an envSchema with z.object() covering each variable, using validators like z.string().url() or z.enum() for NODE_ENV. Call envSchema.parse(process.env) once at startup so invalid configuration fails immediately.
Use z.string().regex() with the pattern /^\+91\d{10}$/ for phone numbers and the 15-character GSTIN regex for tax identifiers. PIN codes use /^\d{6}$/ with a custom error message.
Use z.nativeEnum() for Prisma enums like OrderStatus so the schema stays in sync with the database definition. Reserve z.enum() for fixed string literal sets such as currency codes or job actions.
Floating-point arithmetic introduces rounding errors in currency calculations. The convention uses z.number().int().nonnegative() for paise amounts and pairs them with a formatted string like ₹1,23,456.00 for display.
Validate at every trust boundary: API routes, server actions, and worker job entry points. Never trust data past the boundary; always parse with Zod first before passing it deeper into the application.
