What are @commitlint/lint's main functionalities?

Linting Commit Messages

This feature allows you to lint commit messages using a set of predefined rules. The code sample demonstrates how to use the lint function to check if a commit message follows the specified rules for the commit type and subject case.

const { lint } = require('@commitlint/lint');
const message = 'feat: add new feature';
const rules = {
  'type-enum': [2, 'always', ['feat', 'fix', 'docs', 'style', 'refactor', 'test', 'chore']],
  'subject-case': [2, 'never', ['start-case', 'pascal-case', 'upper-case']]
};

lint(message, rules).then(report => {
  console.log(report);
});
