No console except in catch block Has Fix

• Playground Link

Description

Using console methods is usually for debugging purposes and therefore not suitable to ship to the client. console can expose sensitive information, clutter the output, or affect the performance.

The only exception is using console.error to log errors in the catch block, which can be useful for debugging production.

YAML

id: no-console-except-error
language: typescript
rule:
  any:
    - pattern: console.error($$$)
      not:
        inside:
          kind: catch_clause
          stopBy: end
    - pattern: console.$METHOD($$$)
constraints:
  METHOD:
    regex: 'log|debug|warn'

Example

console.debug('')
try {
    console.log('hello')
} catch (e) {
    console.error(e) // OK
}

Diff

console.debug('') 
try {
    console.log('hello') 
} catch (e) {
    console.error(e) // OK
}
