Cloudflare has open-sourced a new project called workers-graphql-server, which is an Apollo GraphQL server designed for quick setup and use with GraphQL. The platform leverages the strengths of Cloudflare Workers to provide low latency and fast deployment times. A demo GraphQL playground is available on Workers.dev for testing queries and mutations. Additionally, a tutorial has been added to the Workers documentation to guide users in building their own GraphQL server. The project is open-source and welcomes contributions and feedback from the community.
