The specified type '() => { body: string; status: number; }' cannot be assigned to a Svelte type

Question

The specified type '() => { body: string; status: number; }' cannot be assigned to a Svelte type

Attempting to create a simple API endpoint in Svelte using RequestHandler from the index.json.ts file

import type { RequestHandler } from '@sveltejs/kit'

export const get: RequestHandler = () => {
    return{
        body:'Hello from api.',
        status:200
    }
}

Encountering issues with errors:

Type
() => { body: string; status: number; }
is not compatible with type
RequestHandler<Partial<Record<string, string>>, string | null>
.
Type
{ body: string; status: number; }
cannot be assigned to type MaybePromise<Response>.
Type
{ body: string; status: number; }
does not include the necessary properties of type Response: headers, ok, redirected, statusText, and more. ts(2322)

Have attempted to make an accessible endpoint for the project but these errors persist

Answer №1

When it comes to the latest versions of SvelteKit, there are a few key issues that need to be addressed:

To create custom endpoints, they must reside in files with either +server.ts or .js extensions
The handler function's name must be in all uppercase letters
The handler function must return a complete Response object, as indicated by the type error message

Here is an example of how this might look in a +server.ts file:

import type { RequestHandler } from '@sveltejs/kit';

export const GET: RequestHandler = () => {
    return new Response(
        'Hello from the API.',
        { status: 200 }
    );
};
