Introduction

routik adds Zod validation and OpenAPI docs to Express.

What it does

// Instead of manual validation
router.post('/users', (req, res) => {
  if (!req.body.email) return res.status(400).json({ error: 'Email required' });
  // ...
});

// With routik - validation is automatic
router.post('/users', {
  body: { email: 'string.email' },  // validates automatically
  meta: { summary: 'Create user' }
}, (req, res) => {
  // req.body is validated!
  res.json({ id: '1', ...req.body });
});
