AvoidConsoleStatements

Since: PMD 7.5.0

Priority: Medium (3)

Using the console for logging in production might negatively impact performance. In addition, logging could expose sensitive data.

This rule is defined by the following XPath expression:

//FunctionCall[PropertyGet
    [Name[1][@Identifier = 'console']]
    [Name[2][@Identifier]]
  ]
|
//FunctionCall[PropertyGet
    [PropertyGet[1]
        [Name[1][@Identifier = 'window']]
        [Name[2][@Identifier = 'console']]
    ]
    [Name[1][@Identifier]]
  ]

Example(s):

var myObj = getData();
console.log(myObj); // bad
console.debug("myObj:", myObj); // bad
