Apollo GraphQL - 将 .graphql 模式导入为 typeDefs [英] Apollo GraphQL - Import .graphql schema as typeDefs

问题描述

使用 graphql-yoga，您可以通过执行以下操作简单地导入您的模式:typeDefs: './src/schema.graphql'.apollo-server-express 是否有类似的方法?

With graphql-yoga you can simply import your schema by doing the following: typeDefs: './src/schema.graphql'. Is there a similar way of doing so with apollo-server-express?

如果没有，如何从外部 .graphql 文件导入 typeDefs?

If there isn't, how does one import the typeDefs from an external .graphql file?

推荐答案

我找到了一种方法，使用 grahpql-import 这正是我所需要的.请参阅下面的示例代码:

I found a way of doing this by using grahpql-import which does exactly what I needed. See sample code below:

import { ApolloServer } from 'apollo-server-express'
import { importSchema } from 'graphql-import'
import Query from './resolvers/Query'

const typeDefs = importSchema('./src/schema.graphql')
const server = new ApolloServer({
    typeDefs,
    resolvers: {
        Query
    }
})

const app = express()
server.applyMiddleware({ app })

app.listen({ port: 4000 })

更新:graphql-import v0.7+

**

importSchema 现在是异步的，应该作为承诺处理.只需将其包装在 async 函数中，然后简单地 await 即可.

importSchema is now async and should be handled as a promise. Just wrap it in a async function and simply await it.

async function start() {
    const typeDefs = await importSchema(".src/schema.graphql")
}
