Apollo Server 1.0 is a community-maintained, open-source GraphQL server that works with all Node.js HTTP server frameworks, including Express, Connect, Hapi, Koa, AWS Lambda, Restify and Micro. It's built on top of the graphql-js reference implementation and follows principles such as simplicity, performance, and community-driven development. The project has grown rapidly, from zero to over 600 commits by 45 contributors in under a year, with production users including notable companies like Credit Karma, Ticketmaster, OpenTable, Mozilla’s Coral project, express.com, Meteor & Apollo. A tutorial on how to set up a GraphQL server is available, and the team is looking for more contributors and maintainers to help drive the project forward.
