How to extend the schema for custom validation?

[jezikk]

There is a basic schema:

const schema = object({id:number()})

How can I extend the schema with some custom validation? I don't get it how to do it. :(

Have a look at this guide: https://valibot.dev/guides/pipelines/

Here is a code example:

// With validation utility
const schema1 = object({ id: number([minValue(0, 'Only positive numbers are allowed')]) });

// With custom function
const schema2 = object({ id: number([custom((input) => input >= 0, 'Only positive numbers are allowed')]) });

There is no info how to extend the existing schema with only custom validation. I can't figure out how to access the pipeline of existing schema instance.

My question is how I can add a new pipeline validation into schema2 instance?

We work on this feature in PR #211. At the moment it is not possible to access the pipeline of a schema afterwards. As a workaround, you can store the pipeline in a separate variable to reuse it in other places.

OK, thanks.
