Mysql
This project is a MySQL database driver and client for Node.js. It provides a JavaScript implementation of the MySQL protocol to facilitate connecting to, querying, and managing data within MySQL databases.
The driver includes a connection pool manager to maintain a cache of reusable database connections, reducing the overhead of frequent network handshakes. It also supports row-by-row result streaming to process large datasets without loading entire result sets into memory.
Core capabilities cover SQL query execution, the management of database transactions, and the coordination of multiple database hosts. The project includes tools for SQL injection prevention through the sanitization of query inputs and the escaping of identifiers and values. Additionally, it handles data type casting between the database and JavaScript and provides utilities for server monitoring, such as heartbeat pings and statistics retrieval.
Features
