调研方向

Start by reading the Code Connect documentation and the prop mapping behavior around figma.string and example; the issue provides a reproduction using an Errors component that expects a string array. Determine whether transforming mapped values is supported or needs a new API, then confirm the expected generated output for the reproduction. Done means the supported path is documented or the limitation and roadmap status are clarified.

API question

Is there a way to perform operations on the prop values coming from Figma, before they're passed to example?

My scenario is as follows:

  • We have an Errors component that accepts an array of error messages (as strings), ie. <Errors errors={['Error 1', 'Error 2']} />
  • The design component in Figma has a single text property, where the error messages are specified

Currently I have the following in my Code Connect file:

import figma from '@figma/code-connect';

import { Errors } from 'src/components';

figma.connect(
  Errors,
  '[redacted]',
  {
    props: {
      errors: figma.string('text'), // I'd like to transform this to an array, ie. `[figma.string('text')]`
    },
    example: ({ errors }) => <Errors errors={errors} />,
  },
);

Since the Errors component only accepts an array of strings, and not a single string, the above doesn't work. I need to be able to put figma.string('text') into an array, however nothing I tried seems to work.

If I do the following, then Figma renders it as-is, without using the actual value of errors:

example: ({ errors }) => <Errors errors={[errors]} />,

And if I try putting figma.string('text') into an array before passing it to example, then I get <Errors errors={[undefined]} /> output in Figma.

Is there a way to accomplish this? If not currently, is this something that is on the roadmap? Not being able to perform operations on the values coming from Figma is pretty limiting IMO.
