apollo-server-types

What is apollo-server-types?

The `apollo-server-types` package provides TypeScript definitions and utility types for building GraphQL servers with Apollo Server. It includes types for server lifecycle events, request and response handling, and plugin development. This package is primarily used by developers to ensure type safety and to leverage IntelliSense in IDEs for better development experience when working with Apollo Server.

What are apollo-server-types's main functionalities?

GraphQLRequestContext

Defines the context for a GraphQL request. Useful for passing request-specific information through the resolver chain, such as the current user.

{"context": (integrationContext) => { return { user: integrationContext.req.user }; }}

Plugin

Allows the creation of plugins to modify or extend the behavior of Apollo Server at different stages of the server lifecycle.

{"serverWillStart(service) { console.log(`GraphQL Server is starting!`); }}

ValueOrPromise

A utility type that represents a value that could either be returned directly or resolved from a Promise. Useful for functions that might need to perform asynchronous operations.

{"function possiblyAsyncFunction(): ValueOrPromise<string> { return new Promise(resolve => resolve('Hello World')); }}

Other packages similar to apollo-server-types

graphql-tools

A set of utilities to build and mock GraphQL.js schemas. Similar to `apollo-server-types`, it provides a wide range of tools for GraphQL schema definition and manipulation, but it focuses more on schema creation and stitching rather than server lifecycle and request handling.

type-graphql

Allows for creating GraphQL schema and resolvers with TypeScript, using classes and decorators. It's similar in its goal to provide type safety and development utilities for GraphQL servers, but it adopts a different approach by leveraging TypeScript's decorators for schema definition.
