How To Specify A `vue.config.js` Location for `vue-cli`

vue.config.js is an (optional) config file, automatically loaded by @vue/cli-service if present in the project root (next to package.json)

Use the VUE_CLI_SERVICE_CONFIG_PATH environment variable to specify the absolute path to the vue.config.js (relative paths may not work).

{
  "scripts": {
    "build": "VUE_CLI_SERVICE_CONFIG_PATH=$PWD/config/vue.config.js vue-cli-service build"
  }
}
