Get Started

Install

npm i -D wrangler-proxy

Example wrangler.toml

name = "worker"
compatibility_date = "2023-07-02"

[[d1_databases]]
binding = "D1"
database_name = "D1"
database_id = "<d1-id>"

[[kv_namespaces]]
binding = "KV"
id = "<kv-id>"
preview_id = "<same-kv-id-as-above>"

[[services]]
binding = "WORKER"
service = "<worker-name>"
environment = "production"

Start proxy for dev

Remote mode

wrangler dev node_modules/wrangler-proxy/dist/worker.js --remote

Local mode

wrangler dev node_modules/wrangler-proxy/dist/worker.js

Example SvelteKit project

// file: app.d.ts

declare global {
  namespace App {
    interface Locals {
      D1: D1Database;
    }
    interface Platform {
      env?: {
        D1: D1Database;
      };
    }
  }
}

export {};

// file: src/hooks.server.ts

import { connectD1 } from 'wrangler-proxy';

export const handle = ({ event, resolve }) => {
  event.locals.D1 = event.platform?.env?.D1 ?? connectD1('D1');
  // or connectD1('D1', { hostname: 'custom-host-name' });
  // default hostname is `http://127.0.0.1:8787`
  return resolve(event);
};

Using wrangler-proxy to expose workers API

Init worker

npm create cloudflare@2 - .

// file: src/index.ts
import { createWorker } from 'wrangler-proxy';

export default createWorker();

Features

• 😔 Need funding
• 🤷 Not fully tested
• ✅ Complete

D1

import { connectD1 } from 'wrangler-proxy';

Function	Status
prepare()	✅
batch()	✅
dump()	😔
exec()	✅

PreparedStatement

Function	Status
first()	✅
run()	✅
all()	✅
raw()	✅
bind()	✅

Service Bindings

import { connectServiceBinding } from 'wrangler-proxy';

Function	Status
fetch()	✅
connect()	😔

app.d.ts

// app.d.ts

declare global {
  namespace App {
    interface Locals {
      SB: Fetcher;
    }
    interface Platform {
      env?: {
        SB: Fetcher;
      };
    }
  }
}

hooks.server.ts

/// hooks.server.ts

import { connectServiceBinding } from 'wrangler-proxy';

export const handle = async ({ resolve, event }) => {
  event.locals.SB = event.platform?.env?.SB ?? connectServiceBinding('SB');
  return resolve(event);
};

Example usage

event.locals.SB.fetch('http://whatever.fake/send');

http://whatever.fake is required as a dummy hostname. Without a dummy hostname the fetch will fail.

KV

import { connectKV } from 'wrangler-proxy';

Function	Status
put()	🤷
get()	✅
getWithMetadata()	🤷
delete()	✅
list()	🤷

R2

import { connectR2 } from 'wrangler-proxy';

Function	Status

waitUntil

// file: app.d.ts
namespace App {
  interface Platform {
    context: {
      waitUntil(promise: Promise<any>): void;
    };
  }
}

// file: +page.server.ts
import { waitUntil } from 'wrangler-proxy';

export const actions = {
  default: ({ locals, platform }) => {
    waitUntil((async () => {})(), platform?.context);
    return { message: 'success' };
  },
};
