node-config-nuxt

BASED ON nuxt-config

Nuxt module for the node config package

Features

This is a Nuxt module which adds support for the config npm package.

On the server configuration values are read from your configuration files complete with local overrides, environment variables, and everything else the config package provides.

On the client, configuration values are read from state transmitted with the server-rendered HTML, just like the Nuxt state and the Vuex store data.

Setup

• Add node-config-nuxt dependency using yarn or npm to your project
• Add node-config-nuxt to modules section of nuxt.config.js

{
  modules: [
    // Simple usage
    'node-config-nuxt/module',

    // With options
    ['node-config-nuxt/module', {
      clientWhitelist: 'client'
    }],
 ]
}

Usage

Create Config Files

Create a set of configuration files for the config package at the top level of your Nuxt project (or wherever they will be accessible when you run a nuxt command).

Your configuration files must contain a sub-object of values that are safe to send to the client. This prevents the possibility that sensitive data is transmitted to the browser. By default node-config-nuxt will look for an object called client in the config set and only transmit these values to the client.

See "Client Whitelisting" below for more detail.

Retrieving Config Values

NOTE: Avoid using .get(), .has() or any other method that you would normally expect on a config object. They will not be available in the browser.

Inside Components

Access configuration values using the $config property inside Vue components. For example:

{
  methods: {
    doSomething() {
      console.log('A config value!', this.$config.someValue)
    }
  }
}

Outside Components

Configuration data can be read from anywhere like so:

import { config } from 'node-config-nuxt'

console.log(config.someValue)

Client Whitelisting

The node-config-nuxt module does not send all of your configuration data to the browser. You must provide an configuration sub-object that contains a whitelisted set of values that are safe to send to untrusted third parties.

For example:

# default.js
const defer = require('config/defer').deferConfig

module.exports = {
  secretPassword: 'hide this',
  sharedValue: 1000,
  
  client: {
    sharedValue: defer(function() { return this.sharedValue })
  }
}

In the above example, only the sharedValue option will be sent to the browser. Also note the use of the the config package's defer function to keep the config DRY. This is highly recommended.

It is important to keep the shape of the client-safe config object the same as the normal config values. In other words, if a value is accessible as apiServer.uri in the default config, then it should be present at client.apiServer.uri for the client. This way your isomorphic code can always access apiServer.uri and always get the correct value.

Configuring the Whitelist

You can change the name of the client whitelist object with the clientWhiteList option. For example:

# nuxt.config.js
{
  modules: [
    [ 'node-config-nuxt', {
      clientWhiteList: '__client_only'
    }]
  ]
}
