`reply.send()`

Sends the response payload, serializing objects to JSON by default.

Since Fastify 5 Spec ↗

Syntax

reply.send(payload?: any)

Parameters

Name	Type	Required	Description
`payload`	`any`	No	An object, string, Buffer, stream, or Error to send.

Returns

FastifyReply — The reply, for chaining.

Examples

import Fastify from 'fastify';

const app = Fastify();

app.get('/explicit', (req, reply) => {
  reply.code(200).send({ ok: true });
});

app.get('/return', async () => ({ ok: true }));

Notes

In async handlers, returning a value is equivalent to calling send(). Call send() explicitly in callback-style handlers. Sending an Error routes to the error handler.
