Recently written program node. data storage is required for js programs. there are many databases that js can use, such as mongodb and MySQL. However, I still think these databases are too large to be useful, making them more troublesome. So I found node-tiny, a non-relational database, a bit similar to mongodb.Tiny's document describes the fact that when we sear
