vue.js - 如何在NuxtJs中使用Graphql

所以我想将GraphQL实现到NuxtJs中。

现在，我需要在根元素中提供一个提供程序，但是NuxtJs没有给我这个选项。

如何将apolloProvider注入(inject)根 Vue元素中？

我要完成的工作:

https://github.com/Akryum/vue-apollo

const apolloProvider = new VueApollo({
  defaultClient: apolloClient,
})

new Vue({
  el: '#app',
  apolloProvider,
  render: h => h(App),
})

我尝试了什么:

创建一个插件:/plugins/graphql.js:

import Vue from 'vue'
import { ApolloClient, createBatchingNetworkInterface } from 'apollo-client'
import VueApollo from 'vue-apollo'

// Create the apollo client
const apolloClient = new ApolloClient({
  networkInterface: createBatchingNetworkInterface({
    uri: 'http://localhost:3000/graphql'
  }),
  connectToDevTools: true
})

// Install the vue plugin
Vue.use(VueApollo)

const apolloProvider = new VueApollo({
  defaultClient: apolloClient
})

export default apolloProvider

在 .nuxt/index.js 中将apolloProvider导入:

...
import apolloProvider from '../plugins/graphql'
...
  let app = {
    router,
    store,
    apolloProvider,
    _nuxt: {
      defaultTransition: defaultTransition,
      transitions: [ defaultTransition ],
...

不幸的是，这给我带来了两个问题。每次服务器重启时，我的.nuxt目录中的代码都会被擦除。除此之外，它还给我带来以下错误:

最佳答案

也许有点晚，但是有@nuxtjs/apollo插件。

我在使用Nuxt 1.0的博客中使用了此工具，但我仍在Nuxt2上进行一些测试，但是它给了我一些问题。
