How to use the @nuxt/utils.defineAlias function in @nuxt/utils

// Assign options and apply defaults
    this.options = getNuxtConfig(options)

    // Create instance of core components
    this.resolver = new Resolver(this)
    this.moduleContainer = new ModuleContainer(this)

    // Deprecated hooks
    this.deprecateHooks({
      'render:context': 'render:routeContext',
      'render:routeContext': 'vue-renderer:afterRender',
      showReady: 'webpack:done' // Workaround to deprecate showReady
    })

    // Add Legacy aliases
    defineAlias(this, this.resolver, ['resolveAlias', 'resolvePath'])
    this.showReady = () => { this.callHook('webpack:done') }

    // Init server
    if (this.options.server !== false) {
      this._initServer()
    }

    // Call ready
    if (this.options._ready !== false) {
      this.ready().catch((err) => {
        consola.fatal(err)
      })
    }
  }

_initServer () {
    if (this.server) {
      return
    }
    this.server = new Server(this)
    this.renderer = this.server
    this.render = this.server.app
    defineAlias(this, this.server, ['renderRoute', 'renderAndGetWindow', 'listen'])
  }
