我正在我正在研究的NodeJS / Apollo / GraphQL项目中实现schema stitching。它是用TypeScript编写的。
代码是
import {
makeRemoteExecutableSchema,
introspectSchema,
mergeSchemas
} from 'graphql-tools';
import { HttpLink } from 'apollo-link-http';
import fetch from 'node-fetch';
export default async () => {
const link = new HttpLink({
uri:'http://localhost:4545',
fetch
})
const remoteSchema = await introspectSchema(link);
// Make remote executable schema
return makeRemoteExecutableSchema({
schema: remoteSchema,
link
});
}
并且在抱怨
类型文件的引用部分是
export interface HttpOptions {
uri?: string | UriFunction;
includeExtensions?: boolean;
fetch?: WindowOrWorkerGlobalScope['fetch'];
headers?: any;
credentials?: string;
fetchOptions?: any;
}
这似乎是一个bug that has been fixed,但这里似乎并没有解决,尽管我使用的是最新版本和该行
fetch?: WindowOrWorkerGlobalScope['fetch'];
似乎是针对其中一种解决方法的建议,因此,应将其修复。
对于它的价值,我的package.json
是

使用cross-fetch将解决此问题。
