Save Zod schema programmatically to a file

[timheerwagen]

Is there a way to programmatically save a zod schema to a file?

Simple exampe:

import { z } from "zod";
import fs from "fs";

const schema = z.object({ foo: z.coerce.string() });

fs.writeFileSync("foo.js", `const schema = ${JSON.stringify(schema)}`);

Outputs:

const schema = {"_def":{"unknownKeys":"strip","catchall":{"_def":{"typeName":"ZodNever"}},"typeName":"ZodObject"},"_cached":null}

But i need:

const schema = z.object({ foo: z.coerce.string() })

But i need:
const schema = z.object({ foo: z.coerce.string() })

if you want to write the actual code into the file, you can utilize factory from typescript.

Using AST Viewer you can get the exact code samples required for that purpose.

// const schema = z.object({ foo: z.coerce.string() })


  factory.createVariableStatement(
    undefined,
    factory.createVariableDeclarationList(
      [factory.createVariableDeclaration(
        factory.createIdentifier("schema"),
        undefined,
        undefined,
        factory.createCallExpression(
          factory.createPropertyAccessExpression(
            factory.createIdentifier("z"),
            factory.createIdentifier("object")
          ),
          undefined,
          [factory.createObjectLiteralExpression(
            [factory.createPropertyAssignment(
              factory.createIdentifier("foo"),
              factory.createCallExpression(
                factory.createPropertyAccessExpression(
                  factory.createPropertyAccessExpression(
                    factory.createIdentifier("z"),
                    factory.createIdentifier("coerce")
                  ),
                  factory.createIdentifier("string")
                ),
                undefined,
                []
              )
            )],
            false
          )]
        )
      )],
      ts.NodeFlags.Const | ts.NodeFlags.Constant | ts.NodeFlags.Constant
    )
  );

Then you can print that code into a file — find an example implementation in zod-to-ts: https://github.com/sachinraja/zod-to-ts

@RobinTail @timheerwagen i have the same issue, but when using ZodToTs it only gives me the type output, not the actual zod definition.
how did you resolve this?
