Accessing env variables outside the route handlers in hono

[Tiru-99]

I am making a worker service in Hono. In that worker service, I am using the Google Gemini library.

import { GoogleGenAI } from "@google/genai";

const apiKey = Bun.env.GOOGLE_GEMINI_API_KEY;

if(!apiKey){
    throw new Error("GOOGLE_GEMINI_API_KEY not set")
}

export const ai = new GoogleGenAI({
    apiKey 
})

I am trying to put this in one file so that I don’t have to recreate the instance again and again in the route handler, but I am getting this error:

[ ERROR] service core:user:worker: Uncaught ReferenceError: Bun is not defined

    at null.<anonymous> (index.js:18982:14)

✘ [ERROR] The Workers runtime failed to start. There is likely additional logging output above.

I am using Bun + Hono, and deploying it on Cloudflare Workers using the Wrangler CLI. I understand that I can use some workarounds, but I just wanted to know if something like this is actually possible in Hono, or if this is a limitation coming from the Cloudflare Workers runtime itself.
