Category: Best Practices

Description

Debugging with console (such as console.log or console.info) is not considered a bad practice, but these statements can be accidentally left in production code, leading to unnecessary log pollution. It is important to remove or replace these debugging statements to maintain clean and secure production builds.

Non-Compliant Code Examples

console.log(foo) // General-purpose logging which can expose internal information
console.error(foo) // Error logging which can expose sensitive information
console.info(foo) // Informational logging which can clutter production logs
console.warn(foo) // Warning logging which can be excessive for production

Compliant Code Examples

Console.info(foo) // Example placeholder for a custom logging method or library

console.log(foo)
console.error(foo)
