Installing & running the API

Change to api directory

cd api

Install modules

npm install

Run the API

npm start

Run the unit tests

npm test

Run the API integration tests

1. Find the eventstore data folder and delete everything in it; the tests won't pass if there are results from a previous run.
2. Start eventstore
3. cd api
4. Delete any existing read model data: rm -fr db
5. Start API: npm start.
6. Run the tests: npm run test-api

Exploring the API

1. Install https://chrome.google.com/webstore/detail/postman/fhbjgbiflinjbdggehcddcbncdddomop
2. In Postman, import the api/noneoftheabove-localhost.postman_environment.json environment. (Top right in Postman: "Cogwheel-thingy" -> "Manage Environments" -> "Import")
3. Import the collection api/noneoftheabove.postman_collection.json. (Top left in Postman: "Import" button.)

The collection has examples of API calls.
