[zod-graphql-client] Confusion regardings types of variables

[jellelicht]

In your docs you have the following example:

const schema = z
    .object({
        // Provide graphql-specific metadata to your zod schema
        foo: graphqlFieldOptions(z.string(), {
            parameters: {
                bar: variablePlaceholder('$bar')
            }
        })
    })
    .strict();

// Send the query using the client
const client = createGraphqlClient({ endpoint: 'https://example.com/graphql' });
const result = await client.query(schema, {
    operationName: 'YourQueryName', // Optional query name
    variables: {
        bar: {
            type: 'String!',
            value: 'the-actual-value-for-bar'
        }
    }
});

What puzzles me is that the type of the variable is only 'defined' when running the query.
How would I be able to have the String! here be part of the schema, instead of the OperationOptions?

And would it subsequently be possible to have (limited) type-safe variables as well (e.g., make it impossible to pass value: 22 for bar in this example)?

If none of this is in-scope for these libraries, please feel free to close this issue.

I know, that could be confusing indeed. But I don’t have a good idea for different API right now. Given that variables could be referenced multiple times. I would be open for suggestions though.

And would it subsequently be possible to have (limited) type-safe variables as well (e.g., make it impossible to pass value: 22 for bar in this example)?

That would be nice and might be possible, at least for primitive types.
