docker run -v $(pwd)/frontend/build:/app/build frontend-build:latest

Build frontend & backend docker images

docker build -t short-frontend:latest -f frontend/Dockerfile frontend
docker build -t short-backend:latest -f backend/Dockerfile backend

Launch App

docker-compose up

Visit http://localhost:3000

Development

Dependencies

• Go v1.13.1
• Node.js v12.12.0
• Yarn v1.19.1

System Design

Database Modeling

Deployment

Merging from master branch to production branch on Github will automatically deploy the latest code to the production server. This is called continuous delivery in the DevOps world.

In the future, when there are enough automated tests, we may migrate to continuous deployment instead.

Tools We Use

• Drone: Continuous integration written in Go
• Sourcegraph: Code search written in Go
• Code Climate: Automated code review
• ElephantSQL: Managed PostgreSQL service.
• QuickDBD: Draw database diagrams by typing.
