import { pathApi } from "@standev2001/db_connection";
import { getBody, jsonError } from "@standev2001/db_connection/dist/utils";

// The body properties for the games table.
type BodyGame = {
  name: string;
  description: string;
  image: string;
};

export interface Env {
  DB: D1Database;
}

export default {
  async fetch(request: Request, env: Env): Promise<Response> {
    const { pathname } = new URL(request.url);
    pathname.toLowerCase();

    // Get the body of the request.
    const body = await getBody(request);
    if (body === jsonError) {
      return Response.json({ error: jsonError });
    }

    // Check if the path is a game link.
    const gameLink = pathname.startsWith("/games");
    if (gameLink) {
      // Go to the games path and return the response.
      return await pathApi<BodyGame>(env.DB, "games", pathname, body);
    }

    return new Response(`Not found: ${request.url}`, { status: 404 });
  },
};

Head Function: pathApi

The pathApi function is a function that creates a path for your D1Database api.

This will return a response from the database that you can return from your fetch function in your worker.

Example

return await pathApi<BodyGame>(env.DB, "games", pathname, body);

Parameters

async function pathApi<T>(db, table, pathname, body);

• db - The D1Database instance from the env.
• table - The table name. (must be the same as the table name in the database)
• pathname - The pathname of the request: const { pathname } = new URL(request.url);
• body - The body of the request. (best to use getBody function from /dist/utils see usage)
