Does node-mysql Offer Prepared Statement-like Protection Against SQL Injections?

Safeguarding Your Node.js App against SQL Injections

Question: Node.js offers a module called node-mysql for connecting to MySQL databases. However, does it provide a feature similar to PHP's Prepared Statements to prevent SQL injections?

Answer: Yes, the node-mysql library automatically sanitizes user input when you use placeholders and values like you demonstrated in your provided code.

Additional Details:

Your code utilizes the sanitizer module for cross-site scripting (XSS) prevention. Additionally, you're using node-mysql's parameterized query syntax, which calls upon the connection.escape() function internally for escaping characters.

As explained in the node-mysql documentation (https://github.com/felixge/node-mysql#escaping-query-values), this approach effectively prevents SQL injection vulnerabilities. The library automatically escapes any user-supplied data before executing the query.

Recommendation:

Since node-mysql already provides automatic escaping, you do not need to switch to node-mysql-native, which also supports prepared statements.

Conclusion:

With node-mysql's automatic escaping functionality, your Node.js application can effectively safeguard against SQL injections without the need for prepared statements like in PHP.
