How to Import Apollo Client 3 for Vue Apollo?

The release note of Vue-Apollo 3.04 stated that there is now a Apollo Client 3 support. As the Docs of Apollo Client 3 declare ApolloClient, InMemoryCache, HttpLink, are now all in one @apollo/client package - not like previous in single packages.

https://github.com/vuejs/vue-apollo/releases/tag/v3.0.4

https://www.apollographql.com/docs/react/migrating/apollo-client-3-migration/

However there is no change in the doc´s of Vue-Apollo (apollo-client -> @apollo/client ?) on how to apply the new changes. Also the Apollo Client 3 Doc´s stated that for Vue you have to import the ApolloClient from @apollo/client/core

So i tried it my own way, but my imports seems to fail. I got these Error Message from npmm run serve. Seems he wants to import some reactstuff.

     ERROR  Failed to compile with 8 errors                                                                                                             20:25:20
This dependency was not found:

* react in ./node_modules/@apollo/client/react/context/ApolloConsumer.js, ./node_modules/@apollo/client/react/context/ApolloContext.js and 6 others

To install it, you can run: npm install --save react

vue-apollo.js (from old project that worked)

import Vue from 'vue'
import { ApolloClient } from 'apollo-client'
import { HttpLink } from 'apollo-link-http'
import { InMemoryCache } from 'apollo-cache-inmemory'
import VueApollo from 'vue-apollo'

vue-apollo.js (with new apollo client 3)

import Vue from 'vue'
import { ApolloClient } from '@apollo/client/core'
import { InMemoryCache } from '@apollo/client/cache'
import { HttpLink } from '@apollo/client'
import VueApollo from 'vue-apollo'

Question

How to correct import the new apollo client 3 with vue apollo?

Solution

  • Alright after a break i tried this and it worked.

    vue-apollo.js

    import Vue from 'vue'
import { ApolloClient, InMemoryCache, HttpLink } from '@apollo/client/core';
import VueApollo from 'vue-apollo'

    Now the compiler finds everything. Although in the Apollo Client 3 Doc i could only find one reference with the new Client 3 and Vue, it seems all react stuff comes from @apollo/client while Vue and other from @apollo/client/core.
