これを出したい

探した内容

next-with-apolloを見つけるが、Support hooks #74の中でapollo-hookも使いたいなら、next-with-apolloは使わずにwith-apollo/lib/apollo.jsこれをベースにした方が良い、とある
with-apollo/lib/apollo.jsがjsベースなのでtsベースにするために色々探す
How would you type this?を見つけて参考にしてみる
因みにv8以前まで_app.jsを作る時にContainerって言うのも使っていたけど、今では**deprecated**
2.、3.をベースにwithApollo.tsxを考えてみる

withApollo.tsx

基本with-apollo/lib/apollo.jsと同じだが、PageComponent.getInitialPropsに渡す時のctxにapolloClientを生やしている。

...
...

const apolloClient = initApolloClient()
ctx.ctx.apolloClient = apolloClient

let pageProps = {}
if (PageComponent.getInitialProps) {
  pageProps = await PageComponent.getInitialProps(ctx)
}

...
...

下の方にあるfunction createApolloClient内の

uri: "https://api.graph.cool/simple/v1/cixmkt2ul01q00122mksg82pn",

は自分のサーバーへ変更必要。

Page

実際に/pages配下で使う時はNextPageをextendしたapolloClientを盛り込んだ独自のPageを使う。

NextPageWithApolloClient.ts

import { NextPage, NextPageContext } from "next"
import { ApolloClient } from "apollo-client"

export interface NextPageWithApolloClient<P = {}, IP = P> extends NextPage<P, IP> {
  getInitialProps?(ctx: NextPageContext & { apolloClient: ApolloClient<{}> }): Promise<IP>
}

index.tsx


interface Props {
  results: Array<any>
}
// NextPageWithApolloClient を使う
const Index: NextPageWithApolloClient<Props> = props => {
  console.log('props:', props)
  return <>index</>
}
Index.getInitialProps = async ({apolloClient}) => {
                                 // awaitを忘れずに
  const {data, loading, error} = await apolloClient.query({query: QUERY})

  // interface Propsと合わせる必要がある
  return {
    results: []
  }
}
export default Index

_app.tsx

ApolloProviderはwithApollo内で既に作られているので、ここまでシンプルになる。
（もしくはそもそも_app.tsxは作らず、apolloが必要なPageだけでwithApolloを使う）

_app.tsx

import App from "next/app"
import { withApollo } from "../lib/withApollo"

export default withApollo(App)
