javascript - 找不到 schema.graphql 文件( Node graphql-yoga)

Question

我正在按照 how to graphql 教程设置一个简单的 graphql 服务器。

index.js

const { GraphQLServer } = require('graphql-yoga');

// 1
let links = [{
  id: 'link-0',
  url: 'www.howtographql.com',
  description: 'Fullstack tutorial for GraphQL'
}];

const resolvers = {
  Query: {
    info: () => `This is the API of a Hackernews Clone`,
    // 2
    feed: () => links,
  },
  // 3
  Link: {
    id: (parent) => parent.id,
    description: (parent) => parent.description,
    url: (parent) => parent.url,
  }
};

// 3
const server = new GraphQLServer({
  typeDefs:'./schema.graphql',
  resolvers,
});

server.start(() => console.log(`Server is running on http://localhost:4000`));

如您所见，我在创建 GraphQLServer 时引用了我的架构文件。但是，当我运行服务器时，出现以下错误:

/Users/BorisGrunwald/Desktop/programmering/Javascript/GraphQL/hackernews-node/node_modules/graphql-yoga/dist/index.js:418
                throw new Error("No schema found for path: " + schemaPath);
            ^

我的文件结构:

有人能发现错误吗？

Answer 1

您提供了路径./schema.graphql，这使得node在您运行它的目录中查找文件，而不是正确的位置 'src/schema.graphql'。

所以你需要将路径更改为:

//...
typeDefs: 'src/schema.graphql',
//...
