Is it possible to return json body in "+page.server.js"

[Chetan11-dev]

Goal is to return a json response from POST action "+page.server.js".

I tried returning body like this, but did not work

export async function POST({ request }) {
	return {
		status: 204,
		body: {
			content: "some-content"
		}
	};
}

According to the migration guide:

+page.server.js
POST, PUT and PATCH handlers should not return data. They can return an errors object of validation errors that can be used for UI (provided to the component as an errors prop), plus an optional status that defaults to 400 when error is provided and is otherwise ignored...

I'm in the middle of migrating myself so someone else can correct me if I'm wrong but in my app I have /my-endpoint.json/+server.js and I submit POST requests to /my-endpoint.json getting a Response, in your case it would be something like:

// ~/your-endpoint.json/+server.js
import { json } from '@sveltejs/kit';

export async function POST({ request }) {
  return json({
     content: "some-content"
  });
}

json(...) will return a Response object with a status 200, but if you need to return a 204 I think it'd look something like this:

return new Response(JSON.stringify({ content: "some-content" }), {
  headers: {
    'Content-Type': 'application/json'
  },
  status: 204
});

I say "I think" because I actually get a 500 error when I set the status to 204. Other status codes like 200, 201, 202 and even 206 work fine, but 204 doesn't:

Response constructor: Invalid response status code.

How will we get this data back in a +page.svelte file?

+page.svelte const send = async () => { const submit = await fetch('/', { method: 'POST', headers: { 'content-type': 'application/json', accept: 'application/json' }, body: JSON.stringify({ name }) }); const data = await submit.json(); console.log(data); };
`
+page.sever.js
export async function POST({ request }) {
const { name } = await request.json();

return json({
	content: 'some-content'
});

}
