One of the strengths of GraphQL is enforcing data types on runtime. Further, TypeScript and GraphQL Code Generator (graphql-codegen) make it safer by typing data statically, so you can write truly type-protected code with rich IDE assists.
This template extends Apollo Server and Client Example by rewriting in TypeScript and integrating graphql-let, which runs TypeScript React Apollo in graphql-codegen under the hood. It enhances the typed GraphQL use as below:
import { useNewsQuery } from './news.graphql'
const News = () => {
// Typed already️⚡️
const { data: { news } } = useNewsQuery()
return <div>{news.map(...)}</div>
}By default **/*.graphqls is recognized as GraphQL schema and **/*.graphql as GraphQL documents. If you prefer the other extensions, make sure the settings of the webpack loader in next.config.js and .graphql-let.yml are consistent.
Deploy the example using Vercel:
Execute create-next-app with npm or Yarn to bootstrap the example:
npx create-next-app --example with-typescript-graphql with-typescript-graphql-app
# or
yarn create next-app --example with-typescript-graphql with-typescript-graphql-appDownload the example:
curl https://codeload.github.com/vercel/next.js/tar.gz/canary | tar -xz --strip=2 next.js-canary/examples/with-typescript-graphql
cd with-typescript-graphqlInstall it and run:
npm install
npm run dev
# or
