I won't be lying, Claude Code was extremely helpful to write those tests, although it had a lot of issues with properly using in-memory SQLite (db and integration tests) and with parsing responses (integration test).

# Yohoho - A take-home assignment for HolidayPirates
|
|
|
|
This is my take on the take-home assignment I was given for the Backend Engineer
|
|
position at HolidayPirates.
|
|
|
|
The goal is to implement a very small REST API in Clojure. That API provides two
|
|
endpoints :
|
|
|
|
* `POST /items`: creates an item
|
|
* `GET /items`: returns the list of items
|
|
|
|
## Running and testing
|
|
|
|
This project uses Leiningen. Assuming you already have Leiningen installed,
|
|
running the API should be as easy as cloning the repo and issuing `lein run`. By
|
|
default, the server listens on port 3000. To explore the API using Swagger UI,
|
|
you can head to <http://localhost:3000/doc>.
|
|
|
|
To run the unit and integration tests: `lein test`
|
|
|
|
## Structure
|
|
|
|
The source code lies in `/src/yohoho` and is structured as follows:
|
|
|
|
* `app.clj`: ring app and main entrypoint
|
|
* `config.clj`: configuration (database and HTTP server)
|
|
* `db.clj`: functions that directly interact with the database
|
|
* `handlers.clj`: route handlers
|
|
* `helpers.clj`: the infamous file that holds function that are useful but
|
|
couldn't fit anywhere else
|
|
* `routes.clj`: API routes
|
|
* `schemas.cls`: Malli schemas used for validation
|
|
|
|
## Library choices
|
|
|
|
* `reitit`: for handling routes
|
|
* `jetty`: web server
|
|
* `muuntaja`: JSON handling
|
|
* `next.jdbc`: database interface (SQLite)
|
|
* `malli`: validation
|
|
|
|
