There are a few options, you would have to add the names of the fields to the query's projection or you could add an ellipsis to the projection (
...,
) to get the remaining fields without having to name them.

I don't know the names of your fields in your schema, but adding the ellipsis would look like this:
useEffect(() => {
    sanityClient
      .fetch(
        `*[_type == "post"]{
        ...,
        title,
        slug,
        date,
        mainImage{
          asset->{
          _id,
          url
        }
      }
    }`
      )
      .then((data) => setAllPosts(data))
      .catch(console.error);
  }, []);

Thanks,I'll update my working. Then one last question how will i know the exact names that i should use? For example for the date and category ?

You would have to take a look at what you added to the 'name' property of those fields you created in your schema. If this is the guide you're using (or if you're following along with Kap's video on Youtube) it's likely that they're called 'categories' and 'publishedAt'.
So it would probably be something like:

useEffect(() => {
    sanityClient
      .fetch(
        `*[_type == "post"]{
        title,
        slug,
        date,
        mainImage{
          asset->{
            _id,
            url
          }
        },
        publishedAt,
        categories[]->
    }`
      )
      .then((data) => setAllPosts(data))
      .catch(console.error);
  }, []);
