Tools used in project

Backend

The backend is written in Python, requiring at minimum Python version 3.6.8, but is tested with 3.7 and 3.8 as well. Additionally the following libraries are used in the program development:

• aiohttp for the API server

• uvloop for increasing server performance

• keystoneauth1 for authenticating with Openstack

• python-swiftclient for communicating with Openstack Swift API

• cryptography for encrypting session cookies

• click for quickly providing a CLI for the server

Frontend

The frontend is written as an SPA (Single Page Application), in ES6 Javascript. The frontend code is not tested for cross-compilation to ES5. The following libraries are used in writing the frontend:

• Vue.js for site functionality and DOM manipulation

• Vue router for site routing support

• Vue i18n for language support

• Buefy for site styling and components

• Buefy also comes with bulma for css framework

• Lodash for mostly debouncing functions to improve responsivity

Tests

Tests are written to be run with Pytest. The following libraries are used in writing the tests:

• tox for test automation

• cypress for UI test automation

• pytest-timeout for timing out UI tests, which can hang when failing

UI tests also require the WebDrivers for Chrome and Firefox, if tests are to be run locally.

• WebDriver for Chrome

• WebDriver for Firefox

Documentation

The documentation is automatically built with sphinx

Charts

The charts in documentation are made with Dia. The program is old fashioned, but versatile and can be installed without adding repositories, with the added benefit of not requiring the use of browser tools for making the charts. Charts are located in docs/charts, and the exported vector graphics file is linked into the documentation image directory.
