schema to schema code (string)

[Ali-Hussein-dev]

is there an easy way to achieve that?

const schema = z.object(...)
function getSchemaString (schema){
// return "z.object(...)"
}

There isn't an easy or built-in way in Zod to convert a schema instance back into its code string representation (like "z.object(...)"). This is a common request, but the Zod maintainer has stated that code generation from schemas is out of scope for the core library and would break type inference. Attempts to serialize Zod schemas using libraries like devalue, serialize-javascript, or superjson don't work for reconstructing the original code string [discussion].

The closest workaround is to convert your schema to JSON Schema (using something like zod-to-json-schema) and then back to Zod code (using json-schema-to-zod), but this approach is lossy and won't always produce the original code—especially for advanced features like .coerce [discussion]. If you need schema code as a string, you'll need to maintain it separately or build a custom code generator using schema introspection (e.g., .shape), but this is not trivial and not supported by Zod core [issue].

If this answers your question, feel free to close the issue. Let me know if you want more details or have a specific use case in mind!

To reply, just mention @dosu.
