• Launch a terminal in the root folder
• Install all dependencies:

$ yarn install

Running the code

Run locally (browse to http://localhost:3000 to try the API)

$ yarn runlocal

Running unit tests:

$ yarn test

Running integration tests (requires running server; yarn runlocal in other window):

$ yarn itest

Play with offline DynamoDB: http://localhost:8001/shell/
