Adding view count and like button to 11ty

The HSET calls are not just unnecessary, they're a bug. It introduces the possibility of a race condition where a view or like happens between the HGET and HSET. HSETing the values to zero doesn't actually make anything faster or more correct, it just introduces the possibility of overwriting a value that came in moments ago.

Just do hincrby alone, if it doesn't exist it will automatically become 1

You are right. It just should be like so:

Get:

   const likes = (await kv.hget(postTitle, "likes")) || 0

Post:

   const likes = await kv.hincrby(postTitle, "likes", 1);
