Example

Converting struct to GraphQL Object

typeUserExtrastruct {Ageint`description:"Age of the user"`// You can use description struct tag to add descriptionGenderstring`deprecationReason:"Some Reason"`// You can use deprecationReason tag to add a deprecation reason}typeUserstruct {UserIDintUsernamestring`unique:"true"`// You can use unique tag to define if a field would be uniqueExtraUserExtraPasswordstring`exclude:"true"`// You can use exclude tag to exclude a field}funcmain() {// GetGraphQLObject will convert golang struct to a graphQL objectuserType,err:=straf.GetGraphQLObject(User{})// You can then use userType in your graphQL schema}

Using The Schema Builder

typeUserstruct {UserIDint`isArg:"true"`// You can use isArg tag to define a field as a graphql argumentUsernamestring`isArg:"true"`}vardatabase []User= []User{}funcmain() {// GetGraphQLObject will convert golang struct to a graphQL objectuserType,err:=straf.GetGraphQLObject(User{})builder:=straf.NewSchemaBuilder(userType,User{})builder.AddArgumentsFromStruct(object2{})// You can use this function to add more arguments from a structbuilder.AddFunction("CreateUser","Adds a user to database",func(params graphql.ResolveParams) (interface{},error)) {id:=params.Args["UserID"]username:=params.Args["Username"]database=append(database,User{UserID:id,Username:Username})                        })schema:=builder.Schema// You can then use this schema}

Using Middleware In Schema Builder

funcmiddleware(functionfunc(graphql.ResolveParams) (interface{},error),params graphql.ResolveParams) (interface{},error) {fmt.Println("This function will run as a middleware")returnfunction(params)}funcmain() {builder:=straf.NewSchemaBuilder(userType,User{},middleware)builder.AddFunction("SomeFunction","Does Something",someFunction)// Here the middleware function would run everytime before someFunction. middleware function would act as a middleware to all functions added to schema builder.}
