Usage

Display record from version

It might be convenient for some components to only receive the version of the record to display instead of the full record. An example of this might be cases where storing a string is more straightforward than the whole object.

Here, we display a popup editor for a Todo record based on its version.

import {useRecordByVersion} from "./baq/store.js";

function TodoEditorPopup({todoVersion}) {
  const {content} = useRecordByVersion(todoVersion);

  const onSubmit = e => {
    e.preventDefault();
    // Handle saving the edited record...
  };

  return (
    <Popup>
      <form onSubmit={onSubmit}>
        <label>
          Title:
          <input value={title} defaultValue={content.title} />
        </label>

        <label>
          Completed:
          <input
            type="checkbox"
            value={title}
            defaultValue={content.completed}
          />
        </label>

        <button type="submit">Save</button>
      </form>
    </Popup>
  );
}
