DEVELOPMENT NOTES

It is possible to open the system up for “public reactions”, without the need for user registration.

Change the uid to a VARCHAR.
Then, generate a random string in the cookie as the “temporary uid“.

But of course, this is not the safest method – This is very susceptible to spam.

REACTIONS REFERENCE

REACTIONS TABLE

Field	Description
`id`	Primary key. The ID of the post/product/image/video – Whatever you want to add reactions to.
`user_id`	The user who made the reaction.
`reaction`	This is “preset” to `-1` for dislike, `1` for like.

P.S. Feel free to modify to your own needs. For examples:

id is currently BIGINT. Change this to VARCHAR, if you are using something like “SKU” for products.
reaction is pretty much an open field. Come up with your own “reaction codes” – 2 for annoyed, 3 for angry, 4 for rage.
