Last update

Sep 25, 2024

This codemod turns req.params.hasOwnProperty('name') into Object.hasOwn(req.params, 'name'), reflecting the new Fastify v5 approach to property checking.

Before

fastify.get('/route/:name', (req, reply) => {
console.log(req.params.hasOwnProperty('name')); // true
return { hello: req.params.name };
});

After

fastify.get('/route/:name', (req, reply) => {
console.log(Object.hasOwn(req.params, 'name')); // true
return { hello: req.params.name };
});
