MongoDataSource Typescript issues

I started a Typescript project with Apollo Server and have implemented this module the way the documentation expects. I have a data source as shown below as well as my index.ts file that implements the apollo server.

import { MongoDataSource } from "apollo-datasource-mongodb";

export default class Authors extends MongoDataSource {
    getAuthorById(id: string) {
        return this.findOneById(id);
    }
};

const client = new MongoClient("super secret mongo server");
client.connect();

const server = new ApolloServer({
    typeDefs,
    resolvers,
    playground: true,
    dataSources: () => ({
        users: new Authors(client.db().collection("authors")),
        posts: new Posts(client.db().collection("posts")),
    }),
});

I get the following Typescript errors:

index.ts

• Expected 0 arguments, but got 1. ts(2554)

This error is when I attempt to pass client.db().collection("authors") to the Authors constructor. This also happens for Posts.

author.ts

• Property “findOneById” does not exist on type ‘Authors’. ts(2339)

This is from the TypeScript web site https://www.typescriptlang.org/docs/handbook/declaration-files/publishing.html

Note that the “typings” field is synonymous with “types”, and could be used as well.

Also note that if your package.json includes the “files” property the “types” property will be ignored. In that case you need to pass your main declaration file to the “files” property as well.

Also note that if your main declaration file is named index.d.ts and lives at the root of the package (next to index.js) you do not need to mark the “types” property, though it is advisable to do so
