Validating React forms with Cornice/Colander/Pyramid

We are using Cornice for server-side REST API. Frontend is using React. We'd like to have frontend forms to post to Cornice and give proper validation results.

• Are there any standard practices of form submission / error result format

• Are there any standard practices for rendering forms in React so that Cornice validation results would be correctly dropped over the fields (like what Deform et. al. do on the server side.)

Any pointers welcome.

There is a project called Kinto that is doing all of that.

• They have a standard for JSON errors: http://kinto.readthedocs.io/en/stable/api/1.x/cliquet/errors.html?highlight=errors
• They have a way of validating data against a JSON schema: http://kinto.readthedocs.io/en/stable/api/1.x/collections.html?highlight=schema#collection-json-schema
