Mocking meta fields

If your api sometimes sends extra meta information for a list as defined in your model, you can mock them in your server.

For example let's say you want to return the avgRating of all reviews along with your review list.

typescript

vroom.server?.addMetaFields({
  review: {
    // Items will be all filtered items before pagination
    avgRating(items, db) {
      if (items.length === 0) return 0;
      return items.reduce((acc, item) => acc + item.rating, 0) / items.length;
    },
  },
});

TIP

Make sure to include this in a way where your bundler can ignore it in production. See notes on organisation here.
