I've really enjoyed looking at the GraphQL JavaScript reference implementation source [1]. It is well-commented, consistently formatted and structured, and makes frequent references to the spec. The spec itself [2] is very well written too, and I think the project being spec-driven along with the code quality make it a good example. It feels like a lot of thought was put in to making the code well-documented and easy to follow for people new to the project.
