Virtual

A virtual field represents a value which is computed at read time, rather than stored in the database. See the virtual fields guide for details on how to use virtual fields.

Options:

• field (required): The GraphQL field that defines the type, resolver and arguments.
• ui.query (default: '' ): Defines what the Admin UI should fetch from this field, it's interpolated into a query like this:

  query {
    item(where: { id: "..." }) {
      field${ui.query}
    }
  }

  This is only needed when you your field returns a GraphQL type other than a scalar(String and etc.) or an enum or you need to provide arguments to the field.

import { config, createSchema, graphql, list } from '@keystone-6/core';
import { virtual } from '@keystone-6/core/fields';

export default config({
  lists: {
    SomeListName: list({
      fields: {
        someFieldName: virtual({
          field: graphql.field({
            type: graphql.String,
            args: { something: graphql.arg({ type: graphql.Int }) },
            resolve(item, args, context, info) {

            }
          })
        }),
        /* ... */
      },
    }),
    /* ... */
  },
  /* ... */
});
