根据parcel documentation， 我应该能够加载 .graphql 文件。

当我使用宗地导入架构时，我得到了一个对象，但是它不适用于apollo-server-express

API_v1.ts

import typeDefs from './schema.graphql'
import * as resolvers from './resolvers'

const server = new ApolloServer({
  typeDefs,resolvers,})

schema.graphql：

type Query {
  ping: String!
}

导入scema时获得的值

beautified version

{"kind":"Document","definitions":[{"kind":"ObjectTypeDefinition","name":{"kind":"Name","value":"Query"},"interfaces":[],"directives":[],"fields":[{"kind":"FieldDefinition","value":"ping"},"arguments":[],"type":{"kind":"NonNullType","type":{"kind":"NamedType","value":"String"}}},"directives":[]}]}],"loc":{"start":0,"end":31}}

错误

TypeError: Cannot read property 'parse' of undefined
    at Object.parcelRequire.routes/api/v1/index.ts../schema.graphql (/dist/server.js:222:31)
    at newRequire (/dist/server.js:47:24)
    at localRequire (/dist/server.js:53:14)
    at Object.parcelRequire.routes/api/index.ts../v1 (/dist/server.js:240:14)
    ...

我的配置：

• NodeJS v12
• 包裹 v1.12.4
• apollo-server-express v2.9.12

编辑

导入的数据似乎具有DocumentNode（在graphql/language/ast.d.ts中定义）的类型

export interface DocumentNode {
  readonly kind: 'Document';
  readonly loc?: Location;
  readonly definitions: ReadonlyArray<DefinitionNode>;
}

与gql函数的结果类型相同

但是我仍然不知道如何使用它：(
