React Hook Form Issues

This repo is to track issues that I run up against when using RHF with Server Actions and Validation, specifically with AJV & Zod

See branches:

`rhf-data-zod` -- RHF is the source of truth for form data
`rhf-zod-data` -- Zod is the source of truth for form data
`rhf-data-ajv` -- RHF is the source of truth for form data
`rhf-ajv-data` -- AJV is the source of truth for form data

Summary

The following are the business requirements:

1. validate form data on the Client & Server side
2. no unnecessary data in the form submission to the server (this means, if <input> is optional and user did not insert a value, do not send the form field over the wire)

The following are development requirements:

1. determine where to strip out empty string from optional form fields
2. the validator output will server as the source of truth of form data that will be sent to the server (this means, if the validator transforms data, the result of the validation is to return the transformed data and send it to the server)
3. parse/validate once on the client and once on the server

Branches

rhf-ajv-data

Implement ajv as the validator and source of truth of the form data sent to the server

rhf-zod-data

Implement zod as the validator and source of truth of the form data sent to the server

Inconsistency (not sure if a bug)

Upon using ajv type coercion from string to number there is an inconsistency implementation of the RHF method getValues between validation libraries.

For AJV, if coerce is set on the schema, then calling getValues returns the coerced type value. This is not the case with Zod.

See branches rhf-data-ajv & rhf-data-zod
