Main service structure - lanit-tercom-school/studit GitHub Wiki

Introduction

Main-service is the facade for few microservices in StudIT project. It was developed for flexibility of interaction backend with clients. We are using Golang GraphQL library as an implementation of GraphQL technology. Fronted must communicate only with main-service!

  • configuration.go - Golang file for parsing config.json
• docker-conf - Contains the same configuration files as in conf folder, but these configs are used on the production server.
• handler

• helpers
  • helpers.go - Some utils for logging and making requests to other microservices.
• mutations - Contains GraphQL Mutations
