nuxt 3 + cloudfare D1 problems with env.d.ts file

I'm using nuxt 3 with cloudfare D1, but I have encountered some problems. It seems that it cannot read env.d.ts file I have created. I'm getting this error:

500 Cannot read properties of undefined (reading 'env')

500 Cannot read properties of undefined (reading 'env')

I used this repo: https://github.com/tlebeitsuk/nuxt-cloudflare-lucia My configured env.d.ts file:

import { CfProperties, Request, ExecutionContext, KVNamespace, D1Database } from '@cloudflare/workers-types';

declare module 'h3' {
    interface H3EventContext {
        cf: CfProperties,
        cloudflare: {
          request: Request,
          env: {
            MY_KV: KVNamespace,
            DB: D1Database,
          }
          context: ExecutionContext,
        };
    }
}

import { CfProperties, Request, ExecutionContext, KVNamespace, D1Database } from '@cloudflare/workers-types';

declare module 'h3' {
    interface H3EventContext {
        cf: CfProperties,
        cloudflare: {
          request: Request,
          env: {
            MY_KV: KVNamespace,
            DB: D1Database,
          }
          context: ExecutionContext,
        };
    }
}

And here is middleware->auth.ts

import { verifyRequestOrigin } from "lucia"
import { initializeLucia } from "../utils/auth"
import type { User, Session } from "lucia"

let lucia: ReturnType<typeof initializeLucia>

export default defineEventHandler(async (event) => {
  // CSRF protection
  if (!isMethod(event, "GET")) {
    const originHeader = getHeader(event, "Origin") ?? null
    const hostHeader = getHeader(event, "Host") ?? null
    if (
      !originHeader ||
      !hostHeader ||
      !verifyRequestOrigin(originHeader, [hostHeader])
    ) {
      return sendNoContent(event, 403)
    }
  }



  const { DB } = event.context.cloudflare.env

  if (!lucia) {
    lucia = initializeLucia(DB)
  }

  event.context.lucia = lucia


  const sessionId = getCookie(event, lucia.sessionCookieName) ?? null
  if (!sessionId) {
    event.context.session = null
    event.context.user = null
    return
  }

  const { session, user } = await lucia.validateSession(sessionId)
  if (session && session.fresh) {
    appendResponseHeader(
      event,
      "Set-Cookie",
      lucia.createSessionCookie(session.id).serialize()
    )
  }
  if (!session) {
    appendResponseHeader(
      event,
      "Set-Cookie",
      lucia.createBlankSessionCookie().serialize()
    )
  }

  event.context.session = session
  event.context.user = user
})

declare module "h3" {
  interface H3EventContext {
    user: User | null
    session: Session | null
    lucia: ReturnType<typeof initializeLucia>
  }
}

import { verifyRequestOrigin } from "lucia"
import { initializeLucia } from "../utils/auth"
import type { User, Session } from "lucia"

let lucia: ReturnType<typeof initializeLucia>

export default defineEventHandler(async (event) => {
  // CSRF protection
  if (!isMethod(event, "GET")) {
    const originHeader = getHeader(event, "Origin") ?? null
    const hostHeader = getHeader(event, "Host") ?? null
    if (
      !originHeader ||
      !hostHeader ||
      !verifyRequestOrigin(originHeader, [hostHeader])
    ) {
      return sendNoContent(event, 403)
    }
  }



  const { DB } = event.context.cloudflare.env

  if (!lucia) {
    lucia = initializeLucia(DB)
  }

  event.context.lucia = lucia


  const sessionId = getCookie(event, lucia.sessionCookieName) ?? null
  if (!sessionId) {
    event.context.session = null
    event.context.user = null
    return
  }

  const { session, user } = await lucia.validateSession(sessionId)
  if (session && session.fresh) {
    appendResponseHeader(
      event,
      "Set-Cookie",
      lucia.createSessionCookie(session.id).serialize()
    )
  }
  if (!session) {
    appendResponseHeader(
      event,
      "Set-Cookie",
      lucia.createBlankSessionCookie().serialize()
    )
  }

  event.context.session = session
  event.context.user = user
})

declare module "h3" {
  interface H3EventContext {
    user: User | null
    session: Session | null
    lucia: ReturnType<typeof initializeLucia>
  }
}

Specifically this part

js const { DB } = event.context.cloudflare.env

js const { DB } = event.context.cloudflare.env

is responsible am i doing something wrong

Oreki•4mo ago

Hii, were you able to fix this error? if i call my route directly, it returns data successfully, no idea why this would fail

KWACOP•4mo ago

eh unfortunately not, i'm still trying to figure out what could be wrong

Oreki•4mo ago

this went away for me once i created a types folder and added env.d.ts

KWACOP•4mo ago

could you share a repo so i could take a look?

Oreki•4mo ago

Mine's not public, but here's how the structure looks like

apps/
  website/
    nuxt.config.ts
    (...)
    src/
      types/
       env.d.ts
    (...)

apps/
  website/
    nuxt.config.ts
    (...)
    src/
      types/
       env.d.ts
    (...)

// env.d.ts

import { CfProperties, Request, ExecutionContext } from '@cloudflare/workers-types';

declare module 'h3' {
    interface H3EventContext {
        cf: CfProperties,
        cloudflare: {
          request: Request,
          env: Record<string, string>,
          context: ExecutionContext,
        };
    }
}

// env.d.ts

import { CfProperties, Request, ExecutionContext } from '@cloudflare/workers-types';

declare module 'h3' {
    interface H3EventContext {
        cf: CfProperties,
        cloudflare: {
          request: Request,
          env: Record<string, string>,
          context: ExecutionContext,
        };
    }
}

this basically worked for me

KWACOP•4mo ago

env.d.ts specifically needs to be in src->types folder? I thought i can paste this file in root folder of the project

Oreki•4mo ago

if you have src set in nuxt config then it has to go inside src yes that is what i believe lol i am new to nuxt/vue as well so not sure

KWACOP•4mo ago

Okay But looking at this import { CfProperties, Request, ExecutionContext, KVNamespace, D1Database } from '@cloudflare/workers-types'; declare module 'h3' { interface H3EventContext { cf: CfProperties, cloudflare: { request: Request, env: { MY_KV: KVNamespace, DB: D1Database, } context: ExecutionContext, }; } } am I declaring DB correctly?

DB: D1Database

DB: D1Database

And for MY_KV: KVNamespace is not needed in my case? As for now I only need D1

Oreki•4mo ago

that is how'd you declare normally when using cloudflare workers so unless nitro does something with the variables, this should work Also this randomly still appears for me

KWACOP•4mo ago

@Oreki Sorry for pinging I now setup it correctly using command

npm create cloudflare@latest my-nuxt-app -- --framework=nuxt

npm create cloudflare@latest my-nuxt-app -- --framework=nuxt

I was missing some files like

worker-configuration.d

worker-configuration.d

Also I had to downgrade wrangler version because newer one was broken. My drizzle config looks like this:

import { defineConfig } from "drizzle-kit"

export default defineConfig({
  dialect: 'sqlite',
  schema: './server/db/schema.ts',
  out: './server/db/migrations',
  driver: 'd1-http',
  dbCredentials: {
    accountId: 'xxx',
    databaseId: 'xxx',
    token: 'xxx'
  }
})

import { defineConfig } from "drizzle-kit"

export default defineConfig({
  dialect: 'sqlite',
  schema: './server/db/schema.ts',
  out: './server/db/migrations',
  driver: 'd1-http',
  dbCredentials: {
    accountId: 'xxx',
    databaseId: 'xxx',
    token: 'xxx'
  }
})

My question is how to query and receive data from a table? Mine doesn't really work. I have two entries in that table. It shows status 200 but it doens't really print out that info from table getdata.js

import { defineEventHandler } from 'h3'
import { users } from '@/server/db/schema'
import { eq } from 'drizzle-orm'

export default defineEventHandler(async (event) => {
  const db = event.context.db
  
  try {

    const allUsers = await db.select().from(users).all()
    console.log('All Users:', allUsers)
    

    return allUsers
  } catch (error) {
    // Handle any errors that might occur
    console.error('Error retrieving users:', error)  // Log the error message
    throw createError({
      statusCode: 500,
      statusMessage: 'Internal Server Error'
    })
  }
})

import { defineEventHandler } from 'h3'
import { users } from '@/server/db/schema'
import { eq } from 'drizzle-orm'

export default defineEventHandler(async (event) => {
  const db = event.context.db
  
  try {

    const allUsers = await db.select().from(users).all()
    console.log('All Users:', allUsers)
    

    return allUsers
  } catch (error) {
    // Handle any errors that might occur
    console.error('Error retrieving users:', error)  // Log the error message
    throw createError({
      statusCode: 500,
      statusMessage: 'Internal Server Error'
    })
  }
})

i don't really think nitro would have a db key in context?
