no-console-spaces

Disallow leading/trailing whitespace in console arguments. This rule is part of eslint-plugin-conventions.

Quick SummaryCopy Anchor Link

Rule DetailsCopy Anchor Link

Console methods automatically add spaces between arguments, so leading/trailing spaces in strings are redundant.

Why This MattersCopy Anchor Link

ExamplesCopy Anchor Link

❌ IncorrectCopy Anchor Link

// Leading/trailing spaces are redundant
console.log('Value: ', value);  // Double space in output
console.log(value, ' items');   // Double space in output
console.log(' Debug: ', data);  // Leading space unnecessary

✅ CorrectCopy Anchor Link

console.log("hello", "world");

Known False NegativesCopy Anchor Link

The following patterns are not detected due to static analysis limitations:

Dynamic Variable ReferencesCopy Anchor Link

Why: Static analysis cannot trace values stored in variables or passed through function parameters.

// ❌ NOT DETECTED - Value from variable
const value = externalSource();
processValue(value); // Variable origin not tracked

Mitigation: Implement runtime validation and review code manually. Consider using TypeScript branded types for validated inputs.

Wrapped or Aliased FunctionsCopy Anchor Link

Why: Custom wrapper functions or aliased methods are not recognized by the rule.

// ❌ NOT DETECTED - Custom wrapper
function myWrapper(data) {
  return internalApi(data); // Wrapper not analyzed
}
myWrapper(unsafeInput);

Mitigation: Apply this rule's principles to wrapper function implementations. Avoid aliasing security-sensitive functions.

Imported ValuesCopy Anchor Link

Why: When values come from imports, the rule cannot analyze their origin or construction.

// ❌ NOT DETECTED - Value from import
import { getValue } from './helpers';
processValue(getValue()); // Cross-file not tracked

Mitigation: Ensure imported values follow the same constraints. Use TypeScript for type safety.
