Setup

1. make sure you have redis up and running
2. install dependencies npm i
3. add your FIXER_API_KEY in .env file
4. start server npm start
5. run tests npm test (tests are run on Travis upon push to remote)
6. run linting npm run lint (also run as precommit hook and on Travis)

Configuration

For simplicity of local env development, all env variables are located in .env file so for example if your redis server is running on different port then change it there.
