NodeJS Engineer Test

This is the repo for the Culture Trip NodeJs test. If you are here, you probably already made it through the first round, so well done!

This is a take-home test, which we'd expect to take you no more than 2-3 hours.

Your project will be evaluated by:

  • Well thought out software design
  • Testing
  • Clean code

Note: progress as far as you can following the above steps. It is not a requirement to complete all of them. We will value quality over quantity, so a good solution to part of the expected functionality is better than a poor solution to all the requirements.

Good luck!

The Ingestion project

Overview

Culture trip need an internal service so other parts of the business could search hotels by a slug. (a unique identifier name).

So this service needs, first to ingest third parties inventory (extract,transform and save into a database) and then create an endpoint so other services could retrieve hotels.

Acting as third party hotel inventory, we set up an AWS S3 bucket with a json listing hotels in a certain schema structure.

What need to be done

An application that provides RESTful endpoints and follows commonly understood best practices.

We would like you to also implement some basic tests.

This should not have a Frontend, so no views or HTML are required.

Endpoints

The application should have 2 RESTful endpoints which are listed below.

POST /places-to-stay/ingest

That will be the endpoint responsible for a third party inventory ingestion.

You don’t need to worry about setting a cron job that would trigger this endpoint, just bear in mind that the idea that this endpoint will be consumed by a cron job on a daily basis, so this endpoint should not duplicate entries. It should create and update (not required deletion)hotels based on previous ingestions.

The items to insert will be fetched from this S3 file, which is publicly available.

The data retrieved from this JSON file should be transformed to the PlaceToStay , and a slug needs to be created. It should be created based on the hotel name and unique identifier (up to define the logic).

Here is a diagram that should help understand the solution.

GET /places-to-stay/{slug}

This endpoint will return a single PlaceToStay object that corresponds to the given {slug}, represented as JSON

HTTP Status Codes and Exception handling

The application must handle the following exceptions:

  • Bad Request: if the provided {slug} is null or empty
  • Not Found: if the required PlaceToStay cannot be retrieved from the the database
  • Internal Server Error: the application will handle any other exception returning Internal Server Error

Language, Database, Packages and recommendations

  • The test should be completed using Typescript.
  • We would like to use MongoDB as a database.
  • You can launch a local MongoDB instance by running the command docker-compose up, which will run a mongodb container with the credentials listed in the docker-compose.yml file.
  • We have provided a function to connect to a local instance, which makes use of the mongodb npm package. Should you prefer to use a different package, feel free to do so.

Finishing your test

Once you have completed the challenge, please add some very little documentation to the FILL_ME.md file, explaining how to run the server and the tests.

Submitting the test

When you think you have completed the challenge, please do not open a Pull Request. We would like you to zip the folder of your local project (excluding node_modules) and send it through to the email that has been provided to you from our HR department. IMPORTANT The subject of the email should be "NodeJS Engineer Take Home Test". We will evaluate your test and call you for a face-to-face (done remotely) interview, to discuss your solution.
