How nodejs implements database
Apr 21, 2024 am 05:42 AM
Connecting to a database in Node.js requires choosing a database system (relational or non-relational) and then establishing a connection using modules specific to that type. Common modules include mysql (MySQL), pg (PostgreSQL), mongodb (MongoDB), and redis (Redis). After the connection is established, you can use query statements to retrieve data and update statements to modify the data. Finally, the connection must be closed when all operations are completed to release resources. Improve performance and security by following these best practices, such as using connection pooling, parameterized queries, and handling errors gracefully.
