Bug with @apollo/client and InMemoryCache's restore()
new InMemoryCache().restore(window.apolloState || {}) should populate the cache from window.apolloState. It works with apollo-client (version 2.6.x), but not with @apollo/client.
new InMemoryCache().restore(window.apolloState || {}) doesn't populate the cache, it's empty.
You can comment and uncomment the lines with 🕷 and ✅ and clearly see how it works with old version 2.6.x and doesn't work with the 3.x.
import { ApolloClient } from '@apollo/client' // 🕷 It doesn't work with @apollo-client
import { InMemoryCache } from '@apollo/client' // 🕷 same here
// import { ApolloClient } from 'apollo-client' // ✅ But it works with apollo-client v2.6.x
// import { InMemoryCache } from 'apollo-cache-inmemory' // ✅ and apollo-cache-inmemory
npm install
npm run client
npm run server
npm start
