Add field type fields.color()

[tordans]

It would be great to have a fields.color field that shows the native color picker of the browser and returns a hex value.

@zanhk I can create and add custom field components? That sounds great! Do you know of an example on this or some docs?

[zanhk]

@tordans yes you can create custom fields components, I don't think there is docs about it.

for usage you can simply use like this

import { ColorPicker } from "keystatic-components";

....

primary: ColorPicker({
  label: "Primary Color",
  description: "Main color of the site, the selected color will be used to create a color palette based on the chosen color",
}),

If people need I made an icon picker as well

import { Icon } from "@iconify/react";

Nice @zanhk
can you use the ColorPicker as a field in the config? Or it would have to be as item in the wysiwyg editor. I tried to add it directly as a value of a schema item in my config and got an error

[zanhk]

@ismaelrumzan Show me how you are using it and what error you are getting

[ismaelrumzan]

Thanks, here is part of my config (it's part of a singleton)

        sections: fields.blocks(
          {
            card: {
              label: "Cards section",
              schema: fields.object({
                title: fields.text({ label: "Section title" }),
                subtitle: fields.text({ label: "Section subtitle" }),
                background: ColorPicker({ label: "Section background color" }),
                cards: fields.array(
                  fields.object({
                    image: fields.image({
                      label: "Card cover image",
                      directory: "public/images/home",
                      publicPath: "/images/home",
                    }),
                    title: fields.text({ label: "Card title" }),
                  })
                ),
              }),
            },
          },
          { label: "Content blocks" }
        ),

And the front-end error when loading the admin page

./node_modules/.pnpm/keystatic-components@0.0.2_next@14.2.15_react-dom@18.3.1/node_modules/keystatic-components/components/ColorPicker.tsx

Hi @ismaelrumzan sorry for the delayed response, it could be the configuration on tsconfig.json maybe? I will make some repo using ColorPicker open source so you can take a look there
