env variables are empty - Hono
Hello can you help me with some small example how to work locally with env variables?
I tried c.env.API_KEY
i tried env(c)
i tried env(c, "workerd")
each combo with .dev.vars and wrangler.toml vars
Every time when wranger dev it says
(wrangler.toml)
Your worker has access to the following bindings:
- Vars:
- COOKIE_SECRET: "secret"
- AUTH_URL: "https://auth-dev.service.com/"
or
(.dev.vars)
Using vars defined in .dev.vars
Your worker has access to the following bindings:
- Vars:
- COOKIE_SECRET: "(hidden)"
- AUTH_URL: "(hidden)"
using wrangler dev, wrangler dev --local or i turned on remote mode. Same result everytime which is empty object / undefined variable when i console log it.
Any tips? checked github and hono docs. Seems like I am missing something really trivial. How are you using hono locally with env vars? Seems weird that it says Your worker has access to the following bindings but there is nothing :/

Have you tried just accessing the variables directly? IIRC the env object isn’t loggable
my code that worked before with hard coded values is crashing because of null/undefined so my guess is that its not working but i will check and let you know
import { OpenAPIHono, createRoute, z } from '@hono/zod-openapi'
import type { Handler } from "hono"
import { env } from "hono/adapter"
const app = new OpenAPIHono()
const route = createRoute({
method: 'get',
path: '/test',
responses: {
200: {
content: {
'application/json': {
schema: z.string(),
},
},
description: 'Test',
},
},
tags: ['test']
})
const handler:Handler = async (c) => {
const { auth } = env(c)
return c.json(Value is: ${auth})
}
export default app.openapi(route, handler)
is this what you meant?
I'm getting a value:
Looks like you need to access
AUTH_URL or COOKIE_SECRET
Since those are the env vars you have defined.
Or rename one of them to authoops my bad, quickly created test route (facepalm)
do you use OpenAPIHono too?
maybe i should try with normal Hono instance
Here's what I have:
ofc, hmm. what command you use to run server?
is there requirement to do something on my cloudflare account?
wrangler dev -j
The -j is just because I use wrangler.json
Here's my wrangler.json: did you define secret also in this file?
No, in
.dev.vars: damn, nothing works. I will try to create minimal example and let you know. Thank you for your assistance!!
Want me to push mine to Gh?
No need i got it 😦 so stuipid
My index.ts
import { handle } from 'hono/vercel'
import app from '../app.js'
export const config = {
runtime: 'edge'
}
export default {
fetch: handle(app)
};
when i moved to Cloudflare from vercel i didnt make properly
Oh, you are using Next?
everything worked even on this setup except env vars, so when i changed it to this it works now
import app from '../app.js'
export const config = {
runtime: 'edge'
}
export default {
fetch: app.fetch
};
no, i was using vercel for backend
then i got 1 issue with library and moved to cloudflare
thank you very much with help
