Use runtime config for the MONGODB_URI?

[nathan1658]

It seem the URI is required during build time. Is it possible to use runtime config so when I dockerize the application i can do something like

docker run --env NUXT_MONGODB_URI=xxxxxxx

[arashsheyda]

yes you can use runtime config with the variable MONGODB_URI

Hi, can you elaborate more on how can I achieve this? This is my nuxt.config:

export default defineNuxtConfig({
  mongoose: {
    uri: process.env.MONGODB_URI,
    options: {},
  },
})

And this is my dockerfile:

FROM node:lts as builder

WORKDIR /app

COPY . .
RUN npm i
RUN npm run build

# Nuxt 3 production
FROM node:lts

WORKDIR /app

COPY --from=builder /app/.output  /app/.output

ENV NITRO_PORT=80

EXPOSE 80

CMD [ "node", ".output/server/index.mjs" ]

And this is what i want to archive:

docker run --rm -p 8081:80 \
--env NUXT_MONGODB_URI="mongodb+srv://xxxxxxxx" \
nuxt3-test

However, during the docker build process, I can see the error like Missing MongoDB URI. May I know how can I resolve it? Thank you so much!

make sure to use the same variable name in your nuxt.config and docker command, they both should be MONGODB_URI in this case (you can change it to whatever you want, just make sure that it is the same in nuxt.config.mongoose.uri)

docker run -rm -p 8081:80 -e MONGODB_URI=your-mongodb-uri nuxt3-test

export default defineNuxtConfig({
  mongoose: {
    uri: process.env.MONGODB_URI, // this is the uri by default, you can remove this lines
    options: {},
  },
})

Hello,

It appears that the MONGODB_URI is determined at build time and it cannot be modified subsequently. I have tried to update my .env file to:

MONGODB_URI=mongodb://aaaaa

Afterwards, I ran:

npm run build

However, when I attempted to change the MONGODB_URI and run the server:

MONGODB_URI=mongodb://bbbb node .output/server/index.mjs  

The application still used mongodb://aaaaa as the database URI.

Furthermore, in my specific case, I observed that the MONGODB_URI environment variable must be present during build time. If not, I encounter the following error:

(node-resolve plugin) Could not resolve import "#nuxt/mongoose" in xxxxxx .ts using imports defined in xxxxx/package.json.

If I then try to run the server with a different MONGODB_URI:

MONGODB_URI=mongodb://bbbb node .output/server/index.mjs  

I receive another error:

[nuxt] [request error] [unhandled] [500] MODEL is not defined
  at ./.output/server/chunks/index.get9.mjs:13:20  
  at ./.output/server/chunks/nitro/node-server.mjs:2140:47

  at async Server.toNodeHandle (./.output/server/chunks/nitro/node-server.mjs:2391:7)

I would appreciate any guidance or suggestions on how to address these issues. Thanks in advance for your assistance.

@arashsheyda I'm having the same issue as Nathan when trying to build a docker container using Github Actions, I can't change the mongo uri after the build. I'm happy to provide logs from my container if it helps.

Can we please reopen this issue as it is not resolved? Runtime values will not overwrite variables set at build time.

[kevinstory]

Actually, from my testing just now, it looks like this can be overwritten with the environment variable named NUXT_MONGOOSE_URI and not MONGODB_URI.

[arashsheyda]

@kevinstory oh that's great then!! thanks a lot (sorry I don't have docker to test)

works with the latest version (1.0.6)

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

change the config env from MONGODB_URI to NUXT_MONGOOSE_URI as specified in https://nuxt.com/docs/guide/going-further/runtime-config#environment-variables.

can also be but not tested with the options

runtimeConfig: {
  mongoose: { 
      uri: process.env.NUXT_MONGOOSE_URI },
      options: process.env.NUXT_MONGOOSE_OPTIONS },
  }
}
