This project runs a django web server that responds to a single request:

GET /smallest/[start]/[stop]/

Where start and stop are 2 integers

It then returns that smallest positive integer that is divisible by all integers starting at [start] and stopping at [stop].

For example GET /smallest/3/5/ will return 60 since its the smalles number divisible by 3, 4 and 5

Clone the project with:

git clone https://github.com/rwblokzijl/west-assignment.git

All subsequent commands will be run from the project root directory:

cd west-assignment

In a development environment the project needs some dependencies installed. Install them with pipenv:

pipenv install

In production the project can be deployed with docker-compose

If you have changed dependencies through pipenv, update the requirements.txt before deploying with:

pipenv lock --requirements > requirements.txt

Now deploy with docker-compose:

docker-compose up --build

The API can now be reached at the default web port with http://localhost/smallest/1/25/

The project can be run for development with:

pipenv run python src/manage.py runserver

This enables hot reload, debug and other django development features.

The API can now be reached at port 8000 with http://localhost:8000/smallest/1/25/

Running most tests can be done with:

pipenv run python -m unittest

Slow running tests can be run by setting the environment variable $SLOW with:

SLOW=1 pipenv run python -m unittest (These take about 30 seconds on my laptop.)

Most of the interesting engineering is limited to the following files:

• src/assignment/views.py
• test/assignment/test_views.py
• Dockerfile
• docker-compose.yml

• Pipenv can be skipped by installing from requirements.txt
• A Makefile is available with easy shortcuts to all the commands mentioned in this file.
• A .projections file is available that maps src files to test files.
