HTML Validation Errors When Migrating Legacy Forms to React with Formik
I've been struggling with this for a few days now and could really use some help. I'm prototyping a solution and I've been struggling with this for a few days now and could really use some help. Currently developing a new feature that integrates legacy HTML forms into our React application using Formik for form management. During migration, I’m running into validation errors that seem to stem from the way Formik handles HTML input attributes. In my HTML, I had used custom data attributes extensively, but when I adapted the form to JSX syntax, it seems like those attributes are not carrying over correctly. For instance, this is how my input looks in legacy HTML: ```html <input type="text" data-custom="value" /> ``` After converting it to React with Formik, I switched to: ```javascript <Field name="customField" data-custom="value" /> ``` However, the `data-custom` attribute is not being validated as I expected, and I'm receiving warnings about invalid attributes. I’ve tried adjusting the `validate` function in Formik, but it seems the library is not recognizing this custom data attribute during validation. Here’s a simplified version of the validation function I've implemented: ```javascript const validate = values => { const errors = {}; if (!values.customField) { errors.customField = "Required"; } // Additional validation logic... return errors; }; ``` Even with this, the warnings persist. I've also looked into Formik’s documentation on custom validation, but I’m not sure if I'm missing something fundamental. Are there best practices for maintaining custom data attributes in a migration context like this? Should I be using a different approach to pass these custom attributes into Formik, or is there a workaround to ensure that these attributes are validated properly? Any insights or examples would be greatly appreciated! I'm working on a service that needs to handle this. Any help would be greatly appreciated! What am I doing wrong? I've been using Javascript for about a year now. What are your experiences with this?
