About

IP Locate is a tool for querying and plotting geographic information for ipv4 and ipv6 addresses via the MaxMind GeoLite2 dataset.

Built with

• TypeScript
• Jest
• ReactJS
• Styled Components
• Fastify
• Terraform

development

The development environment is configured using docker-compose. In order to run iplocate locally:

1. Configure environment:
   • copy the dev.example.env file to a new file called .env: cp example.env .env
   • add MaxMind account id and license key credentials to the .env file where appropriate. Access is free and an account can be created here.
2. Start the environment:
   • From the root of the project, start environment using docker: docker-compose up --build
   • Local changes in backend/src and frontend/src will be hot-reloaded
   • Other changes will require stopping and starting the environment
3. Navigate to http://localhost in a browser

testing

In order to run unit tests

1. Install backend dependencies (outside of docker)
   • cd ./backend
   • npm install
2. Install frontend dependencies (outside of docker)
   • cd ./frontend
   • npm install
3. From either directory
   • Run unit tests: npm run test
   • Run unit tests with coverage: npm run test:coverage
   • Format code using prettier: npm run format
   • Check formatting: npm run format:check

Contributing

Pull requests are welcome. Prior to committing, run unit tests and formatting. Code coverage is required to be above 90%.

CI/CD

GitHub Actions is used for CI/CD. Backend CI configuration can be found in .github/workflows/backend.yml, and frontend configuration can be found in .github/workflows/frontend.yml. Every PR triggers the following steps in both:

1. Install nodejs and dependencies (npm ci)
2. Ensure prettier code style (npm format:check)
3. Run tests (npm run test:coverage)
4. Build production application (npm run build)

Every push to master triggers the following deployment steps with the deploy workflow in .github/workflows/deploy.yml

1. Deploy infrastructure changes using terraform
2. Deploy backend using serverless framework
3. Deploy frontend to Netlify
