Description
Unfortunately Nuxt 3 doesn't allow to change env variables used in the nuxt.config.ts at runtime. They are build-time only.
In our pipeline we first build nuxt and then add the environment variables. However, the nuxt.config.ts will still have the undefined values. That's why we need to be able to edit the config at runtime.
The following nuxt config works fine in development but BACKEND_IMAGES_ENDPOINT is undefined in production deployment:
export default defineNuxtConfig({
// also doesn't work with NUXT_ or NUXT_PUBLIC_ prefix
domains: [process.env.BACKEND_IMAGES_ENDPOINT],
alias: {
"/images": `${process.env.BACKEND_IMAGES_ENDPOINT}/images`
},
},
})I am using the IPX provider and could create a yarn patch to fix this issue for my specific case:
