We need to install the graphql package github.com/graph-gophers/graphql-go. Install the package using go get -u github.com/graph-gophers/graphql-go

We will build out the schema for our trivial todo app GraphQL API. Therefore we will be defining our schema and resolvers in schema.go and resolver.go respectively. The graphql-go will parse and validate the schema and resolvers for us. It will panic in case of any errors.

We will setup the graphql endpoints and register their respective handlers.

Run the main binary found inside cmd directory, it wil start a GraphQL API server on port :8080. You can use the sample curl request to test that it is responding to graphql queries as expected.

 curl -X POST -H "Content-Type: application/json" --data '{ "query": "{ tasks {id name description startDate endDate done} }" }' https://localhost:8080/tasks
