How to access Cloudflare Worker Bindings?

[hrueger]

Hi @markusahlstrand, I'm currently building an api and looking for a framework. tsoa + tsoa-hono looks awesome! I just cannot figure out how to access Bindings for deploying to Cloudflare Workers... Is there an example on how to do this? Specifically, I'd like to talk to a D1 database. Thanks in advance!

Never mind, I figured it out by looking at the code of https://github.com/authhero/auth. For anyone interested:

• create a index.ts file wrapping app.fetch:

  
  import { ExecutionContext } from "hono";
  import { Env } from "./_helpers/Env";
  import app from "./app";
  import { PrismaClient } from "@prisma/client";
  import { PrismaD1 } from "@prisma/adapter-d1";

const server = { async fetch(request: Request, env: Env, ctx: ExecutionContext) { const adapter = new PrismaD1(env.D1_MAIN); return app.fetch( request, { ...env, prisma: new PrismaClient({ adapter }) }, ctx, ); }, };

export default server;

everything attached to the env here can be used by adding `@Request() request: RequestWithContext` as a parameter to your route handler. Now, you can use `request.ctx.env.prisma`.

@markusahlstrand I had to patch tsoa-hono since wrangler complained about now knowing about Buffer here:

[ERROR] ReferenceError: Buffer is not defined

nodejs_compat was enabled. Maybe you want to include this? tsoa-hono-npm-1.2.1-04da50d363.patch

Hi! Yes, it's on my todo list to see if we somehow can remove that dependency..

Great to know, thanks! It works fine with the patch though, so no worries.
