1. Instructions to run services locally

Pre-requisites

• Ensure you have Docker Desktop (>= v4.22.2) installed (https://docs.docker.com/get-docker/)
• Ensure you have .env files for system variables, can refer to .env.example to check. If there are missing variables, please contact team members. (.env file needed at root-level and all services excluding client)
• Ensure at least 1 question present before trying the matching and collaborative features (see below on further instructions)

Option 1: Using Docker Compose (run all services easily)

1. In the root of the project
   • run docker-compose build
   • run docker-compose up

Option 2: Using npm (starts each service individually)

There are 10 services that needs to be started individually should you choose to use npm to start the application.

Warning: .env.example provided is meant for running using docker-compose. To run using npm, please change all urls in the .env file to localhost. .env for certain services also requires additional fields only found in root-level .env

eg. http://api-gateway:5000 => http://localhost:5000

For this reason, using npm is Not recommended.

For all services

1. Run npm i to install required packages

To run client alone

1. In the /client directory, run npm start

To run backend alone (test out endpoints using postman)

1. In each of the api/* directory, run npm run dev
2. In each of the socket/* directory, run npm run dev

2. Populating Question data and Admin account

Pre-requisites

• Services was started using docker-compose
• Mysql and MongoDB containers are currently running

Admin Account

1. Open the terminal of the mysql container and run the following commands
2. Run mysql -u root -p peerprep
3. Enter the password example when prompted
4. Run source /dump/CreateUsers.sql
   • If there are existing users, run DELETE FROM users; and DELETE FROM user_infos; first

This creates an admin user account with privileges to manage the questions database

• Email: [email protected]
• Password: password

Question data

This loads in our team's curated question list for easy setup

1. In local machine's terminal, run docker-compose exec mongodb mongorestore /data/dump
   • This command can only be executed once
