ViewsHow to use plugin's data in a nuxt.config.js file?
My plugin, env.js:
export default async (_ctx, inject) => {
const resp = await fetch('/config.json')
const result = await resp.json()
inject('env', result)
// eslint-disable-next-line no-console
console.log('env injected', result)
return result
}
Then an idea was to use it's data inside nuxt.config.js to inject into publicRuntimeConfig:
import env from './plugins/env.js'
publicRuntimeConfig: {
test: env,
},
Then in a browser console i'm checking it:
this.$nuxt.$config
It shows me:
instead of a value, though this.$nuxt.$env shows the correct values:
What's wrong?
UPDATE 1
Tried Tony's suggestion:
// nuxt.config.js
import axios from 'axios'
export default async () => {
const resp = await axios.get('/config.json')
const config = resp.data
return {
publicRuntimeConfig: {
config
}
}
}
It cannot fetch config.json, but if i point it to an external resource: "https://api.openbrewerydb.org/breweries" it does work.
Intention of this question, is to have config.json where a user could simply change variable values there (from a compiled code) and change endpoints without a re-build process.

In nuxt.config.js, your env variable is a JavaScript module, where the default export is the function intended to be automatically run by Nuxt in a plugin's context. Importing the plugin script does not automatically execute that function. Even if you manually ran that function, it wouldn't make sense to use an injected prop as a runtime config because the data is already available as an injected prop.
If you just want to expose config.json as a runtime config instead of an injected prop, move the code from the plugin into an async configuration:
// nuxt.config.js
export default async () => {
const resp = await fetch('/config.json')
const config = await resp.json()
return {
publicRuntimeConfig: {
keycloak: config
}
}
}
