GraphQL API Development with Apollo Server

Why GraphQL?

GraphQL provides a complete description of your API data.

Setup Apollo Server

import { ApolloServer } from '@apollo/server';
import { startStandaloneServer } from '@apollo/server/standalone';

const typeDefs = `#graphql
  type Book {
    title: String
    author: String
  }
  type Query {
    books: [Book]
  }
`;

const resolvers = {
  Query: {
    books: () => books,
  },
};

const server = new ApolloServer({ typeDefs, resolvers });
const { url } = await startStandaloneServer(server);

Mutations

Handle data modifications with mutations.
