示例1: count
export const resolver = (pubsub: PubSub, logger?: Logger) => ({
Query: {
count(obj, args, context: { Count: ICounterRepository }) {
logger.debug('quering the count table');
return context.Count.getCount();

Mutation: {
async addCount(obj, { amount }, context: { Count: ICounterRepository }) {
logger.debug('adding count...');
await context.Count.addCount(amount);
let count = await context.Count.getCount();
