Question

我有一个反应16应用程序，我只是想尝试升级到apollo2。差不多相同的代码适用于Apollo1。

这是我的 index.js 文件

import React from "react"
import ReactDOM from "react-dom"
import { ApolloClient } from 'apollo-client';
import { HttpLink } from 'apollo-link-http';
import { ReduxCache, apolloReducer } from 'apollo-cache-redux';
import { ApolloProvider } from 'react-apollo';
import Routes from "./router/routes"
import getStore from "./store"
import registerServiceWorker from "./registerServiceWorker"

//See https://github.com/rportugal/apollo-cache-redux
const apolloStore = getStore(apolloReducer);
console.log('index.js: apolloStore:', apolloStore);

const cache = new ReduxCache({ apolloStore });
console.log('index.js cache:', cache);

const client = new ApolloClient({
  link: new HttpLink({ uri: '${FULL_HOST}/qe' }),
  cache,
});
console.log('index.js client:', client);

ReactDOM.render(
  <ApolloProvider client={client} store={apolloStore} >
    <Routes />
  </ApolloProvider>,
  document.getElementById("root")
)

registerServiceWorker()

store.js

import { createStore, applyMiddleware, compose } from "redux"
import { persistStore, autoRehydrate } from "redux-persist"
import thunk from "redux-thunk"
import createReducers from "./reducers"

const isProd = process.env.NODE_ENV === "production"

const middlewares = [
  thunk,
,
].filter(m => m) // We want to conditionally add middlewares so we need to remove falsey values

const middleware = applyMiddleware(...middlewares)
export default function getStore(apolloReducer) {
  const store = createStore(
    createReducers({
      apollo: apolloReducer,
    }),
    /* eslint-disable no-underscore-dangle */
    isProd || !window.__REDUX_DEVTOOLS_EXTENSION__
      ? undefined
      : window.__REDUX_DEVTOOLS_EXTENSION__(),
    /* eslint-enable */
    compose(middleware, autoRehydrate())
  )

  persistStore(store, {
    // We must add the key name for any reducer that we wish to persist here
    whitelist: ["pageBuilder", "tracking"],
  })

  return store
}

reducers.js

import { combineReducers } from "redux"
import logs from "./logs"

import {
  createAudienceName,
  createAudienceDescription,
} from "./create-audience"

function createReducer(withReducers) {
  return combineReducers({
    createAudienceDisplayError,
    createAudienceDescriptionError,
    createAudienceNameError,
    logs,
    ...withReducers,
  })
}

export default createReducer

当我启动我的应用程序时 - 我收到此错误。

Could not find "store" in either the context or props of "Connect(App)". Either wrap the root component in a <Provider>, or explicitly pass "store" as a prop to "Connect(App)".

我需要做些什么来解决这个特定的错误？

更新如果我导入以下文件

import {Provider} from "react-redux"

并将我的反应渲染方法更改为：

  ReactDOM.render(
  <ApolloProvider client={client}>
    <Provider store={store}>
      <Routes/>
    </Provider>
  </ApolloProvider>,
  document.getElementById("root")
)

这个错误消失但它开始抱怨任何地方然后我使用gql 例如：

import { gql } from "react-apollo"
const EDIT_ROUTE = gql`
  mutation editRoute(

gql未定义。我应该从其他地方导入gql吗？

Answer 1

Apollo客户端2.0不再导出gql并要求您直接导入graphql-tag

而不是import { gql } from "react-apollo" 使用import gql from "graphql-tag"
