defineMongooseModel Schema is not defined when running in production (nuxt start)

[gamegine]

hello, I'm trying to deploy my application in production. and I encountered a problem when executing API requests once the application is deployed which returns me error 500 TodoSchema is not defined. here are the steps I use for prod deployment

npm ci
npm run build
node .output/server/index.mjs # or nuxt start

the problem does not appear during the development (nuxt dev) I attach the configuration of my application below would there be a configuration step necessary to include the server/models folder in nuxt ??

	"dependencies": {
		"nuxt": "^3.11.2",
		"nuxt-mongoose": "^1.0.5",
		"vue": "^3.4.21",
		"vue-router": "^4.3.0"
	},

nuxt.config.ts

// https://nuxt.com/docs/api/configuration/nuxt-config
export default defineNuxtConfig({
	devtools: { enabled: true },
	$development: {
		modules: ["@nuxtjs/eslint-module"],
	},
	modules: ["nuxt-mongoose"],
	mongoose: {
		uri: process.env.CONN_STR,
	},
});

server/models/todo.schema.ts

import { defineMongooseModel } from "#nuxt/mongoose";
export const TotdSchema = defineMongooseModel({
	name: "Todo",
	schema: {...},
});

server/api/todos/[_id].get.ts

export default defineEventHandler(async (event) => {
	try {
		return await TodoSchema.findOne({ _id: event.context.params?._id });
	} catch (error) {
		return error;
	}
});

Hi @gamegine, no this is find & should work already! what kind of server do you have?

[gamegine]

hello, i run on docker node:20.11.1-alpine image i have try to run dev inside the container is working but not the nuxt build/start

[gamegine]

nuxt start

hello, I found the cause of the problem. its 'uri: process.env.CONN_STR' , in defineNuxtConfig something I didn't know yet about env variables in nuxt during the build nuxt incorporates static values of the variable of env and not the env.xxx when I launch my app the value was not set from env but set on val of build state and therefore set to undefined//null I looked at how the module was loaded, and I saw that if the uri was not set the setup was interrupt

node_modules/nuxt-mongoose/dist/module.mjs

  async setup(options, nuxt) {
    if (nuxt.options.dev) {
     ...
    }
    if (!options.uri) {
      logger.warn("Missing MongoDB URI. You can set it in your `nuxt.config` or in your `.env` as `MONGODB_URI`");
      return;
    }
/// setup module
...

being directly checked from options this makes it impossible to use runtimeConfig{mongoose:{uri}}

hey @gamegine, sorry for the late response

we changed the behaviour some time ago so if uri is not provided to proceed, just published a new version and that should work.

hello, I updated, and that solved the problem :) I also changed my nuxt config to load the config from the env variables in runtime and it also works.

export default defineNuxtConfig({
	///
	modules: ["nuxt-mongoose"],
	runtimeConfig: {
		mongoose: { uri: process.env.NUXT_MONGOOSE_URI },
	},
});

it might be interesting to add this point to the documentation and change the default config env variable from MONGODB_URI to NUXT_MONGOOSE_URI as specified in https://nuxt.com/docs/guide/going-further/runtime-config#environment-variables. (subject of pull request #44 )
