Last update

This codemod converts reply.res moved to reply.raw.

🚦 Impact Level: Minimal

What Changed

If you previously used the reply.res attribute to access the underlying Request object you will now need to use reply.raw.

Before

fastify.get('/example', (request, reply) => {
    const rawResponse = reply.res;
    rawResponse.writeHead(200, { 'Content-Type': 'text/plain' });
    rawResponse.end('Hello, World!');
});

After

fastify.get('/example', (request, reply) => {
    const rawResponse = reply.raw;
    rawResponse.writeHead(200, { 'Content-Type': 'text/plain' });
    rawResponse.end('Hello, World!');
});
