Welcome to Zesje

Zesje is an online grading system for written exams.

Development

Setting up a development environment

We recommend using the Conda tool for managing your development environment. If you already have Anaconda or Miniconda installed, you may skip this step.

Install Miniconda by following the instructions on this page:

https://conda.io/miniconda.html

Create a Conda environment that you will use for installing all of zesje's dependencies:

conda create -c conda-forge -n zesje-dev python=3.6 yarn

Then, activate the conda environment:

conda activate zesje-dev

You should see (zesje-dev) inserted into your shell prompt. This tells you that the environment is activated.

Install all of the Javascript dependencies:

yarn install

Install all of the Python dependencies:

pip install -r requirements.txt -r requirements-dev.txt

Unfortunately there is also another dependency that must be installed manually for now (we are working to bring this dependency into the Conda ecosystem). You can install this dependency in the following way on different platforms:

Running a development server

Activate your zesje development environment and run

yarn dev

to start the development server, which you can access on http://127.0.0.1:8881. It will automatically reload whenever you change any source files in client/ or zesje/.

Running the tests

You can run the tests by running

yarn test

Building and running the production version

Code style

Python

Adhere to PEP8, but use a column width of 120 characters (instead of 79).

If you followed the instructions above, the linter flake8 is installed in your virtual environment. If you use Visual Studio Code, install the Python extension and add the following lines to your workspace settings:

"python.linting.pylintEnabled": false,
"python.linting.flake8Enabled": true,
"[python]": {
    "editor.rulers": [120]
},

If you use Atom, install the linter-flake8 plugin and add the following lines to your config:

".source.python":
  "editor":
    "preferredLineLength": 120

Javascript

Adhere to StandardJS.

If you use Visual Studio Code, install the vscode-standardjs plugin.

If you use Atom, install the linter-js-standard-engine plugin.

Adding dependencies

Server-side

If you start using a new Python library, be sure to add it to requirements.txt. Python libraries for the testing are in requirements-dev.txt. The packages can be installed and updated in your environment by pip using

pip install -r requirements.txt -r requirements-dev.txt

Client-side

Yarn keeps track of all the client-side dependancies in package.json when you install new packages with yarn add [packageName]. Yarn will install and update your packages if your run

yarn install
