Autograd is a web app that provides code autograding for schools and university programming course. Currently it supports c++ language only.

Installation

TBD

Design Overview

The project is divided into two main components:

• cmd
• db
• frontend
• pkg
• proto
• testdata

cmd

The cmd folder contains the entry point for the cli application

db

The db folder contains the database schema and migration file & sqlc queries

frontend

The frontend folder contains the frontend application written in reactjs

pkg

The backend is written in Go under pkg folder and have this several components:

• config: hold the configuration & env for the application
• core: hold the core logic of the application
  • each sub-package represent the domain of the application
    • the domain creation, which part belong to which domain is up to the team and should be based on business process
  • inside sub-package there is *_cmd & *_query package that is the public API written in connectrpc framework
  • for data persistence, we interfacing using gorm & sqlc. Gorm is initially used, but will migrated to sqlc for better performance
• dbconn: hold the database connection and migration logic
• dbmodel: hold the database model, use to query using gorm
• httpsvc: wiring the service and http handler
• fs: hold the file system to store & retrieve the file
• jobqueue: handle jobqueue, it has outbox pattern implemented under outbox package
  • outbox: hold the outbox pattern implementation. It is used to do async operation
• logs: hold the logger configuration
• mailer: handle mailing feature, under it is mailing provider implementation
• pb: the generated protobuf file
• service: the wiring for the cmd & query
• xsqlc: the generated sqlc file

proto

The proto folder contains the protobuf file definition

testdata

The testdata folder contains the test data for assignemnt & submission

Development

• Prerequisites
  • Golang v1.22+
  • NodeJS v18+
  • pnpm
  • postgres v16
  • mailhog

  • sqlc
  • sql-migrate
• Clone the project
• cd to the project directory
• copy .env file from .env.example
  • cp .env.example .env
• run go mod tidy to install the backend dependencies
• cd to the frontend directory run pnpm install to install the frontend dependencies

Migrate Database

• run make db-migrate-up

Running Backend Service

• run the postgres & mailhog service
• run make run-server to run the backend service

Running the Frontend Service

• cd to the frontend directory
• run pnpm dev to run the frontend service

Create Initial Admin
