apollo-datasource-graphql | Apollo DataSource to connect to GraphQL API | GraphQL library

There is an open PR in the apollo-datasource-graphql repo: https://github.com/poetic/apollo-datasource-graphql/pull/11

There is a solution which helps you in the meantime. Change your import from:

import { GraphQLDataSource } from 'apollo-datasource-graphql';

to

import { GraphQLDataSource } from 'apollo-datasource-graphql/src';

And finally, I found an interesting part during the research. I found a section in the docs from apollo server where you can define an api as a ressource and not a graphql server. Which is actually the case in your provided code.

In Addition, if you have other issues that might block tsc from compiling, please go under your node_modules into the apollo-datasource-graphql folder and go to the query function. There is the desired type for the options parameter. And as the docs say you need to provide the query you passed as first parameter also in the options as a query like this

const response = await this.query(ARTICLE_QUERY, { query: ARTICLE_QUERY, variables: { id }});
