Endpoint with PDF return

[rough dawn]

Create an endpoint for me that takes an ID as param, looks it up in a Turso table called 'invoices', then generates a pdf file with mock content using jspdf and returns it as download.

Hi @rough dawn. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

To create an endpoint that generates and returns a PDF file based on an ID lookup in a Turso database, we need to combine several concepts. However, I must point out that the knowledge sources provided don't contain specific information about generating PDFs with jspdf in Astro. I can provide a partial answer based on the available information about creating endpoints and using Turso with Astro.

Here's an outline of how you could create such an endpoint:

1. First, set up Turso in your Astro project as described in the Turso & Astro guide (https://docs.astro.build/en/guides/backend/turso/#_top).

2. Create an endpoint file in your src/pages directory, for example src/pages/invoice/[id].pdf.ts.

3. In this file, create a GET function that will handle the request:

import type { APIRoute } from 'astro';
import { turso } from '../../turso';

export const GET: APIRoute = async ({ params }) => {
  const { id } = params;

  // Query the invoice from Turso
  const { rows } = await turso.execute({
    sql: 'SELECT * FROM invoices WHERE id = ?',
    args: [id]
  });

  if (rows.length === 0) {
    return new Response(null, {
      status: 404,
      statusText: 'Invoice not found'
    });
  }

  const invoice = rows[0];

  // Here you would generate the PDF using jspdf
  // This part is not covered in the provided knowledge sources
  // const pdf = generatePDF(invoice);

  // For now, we'll return a mock PDF response
  return new Response('Mock PDF content', {
    status: 200,
    headers: {
      'Content-Type': 'application/pdf',
      'Content-Disposition': `attachment; filename="invoice-${id}.pdf"`
    }
  });
};

This endpoint does the following:

1. It uses the ID from the URL parameters to query the Turso database.
2. If an invoice is found, it would normally generate a PDF (but we don't have information on how to do this with jspdf in Astro).
3. It returns a response with the appropriate headers to trigger a download.

Note that this is a partial solution. The PDF generation part is missing because the knowledge sources don't provide information about using jspdf or any other PDF generation library with Astro. You would need to research how to integrate jspdf or a similar library with Astro to complete this functionality.

Also, remember that for this endpoint to work in SSR mode, you need to enable on-demand rendering (https://docs.astro.build/en/guides/on-demand-rendering/) for your Astro project.

For more information on creating endpoints in Astro, you can refer to the Endpoints guide (https://docs.astro.build/en/guides/endpoints/#server-endpoints-api-routes).
