consoleCalls

Reports calls to console methods.

✅ This rule is included in the ts preset.

Console methods like console.log, console.warn, and console.error are useful during development but should typically be removed before shipping to production. They can expose sensitive information to users and clutter the browser console.

Examples

❌ Incorrect

function processUser(user: User) {
  console.log("Processing user:", user);
  return user.name;
}

✅ Correct

function processUser(user: User) {
  return user.name;
}

Options

This rule is not configurable.

When Not To Use It

If your project intentionally uses console methods for logging in production, such as in a Node.js server application, you might choose to disable this rule. You might also disable it if you have a build step that strips console calls from production builds.
