## Setting up development environment

### Installing dependencies

The minimum requirements are:
- GNU Bash
- [GNU Coreutils](https://www.gnu.org/software/coreutils/)
- Git
- Node.js (version 16 and above)

To install the project dependencies, run

```sh
# install dependencies
npm install

# install dependencies for modules
npm install --dir node_modules/plain-modal
npm install --dir node_modules/plain-draggable

# install linting and building tools
npm install -g rollup standard
```


## Style guidelines

We use [StandardJS](https://standardjs.com/) with pre-defined ESLint rules to ensure a consistent coding style and catch potential bugs. For checking lint, run

```
npm run lint
```


## Linking Package

```sh
# without code minified
npm run build

# with code minified
PRODUCTION=true npm build
```
