## requirements
- node.js
- yarn
- evtest
- node.js
- [nvm](https://github.com/nvm-sh/nvm)
## setup
## setup (as root)
- clone the project
`git clone https://git.velvettear.de/velvettear/ninwa.git`
- install nvm
- enter the project directory
`cd ninwa`
- to load nvm restart your terminal or `source ~/.nvm/nvm.sh`
- installed required modules
`yarn install`
- clone the project (to '/opt/ninwa')
`git clone https://git.velvettear.de/velvettear/ninwa.git /opt/ninwa`
- modify `config.json` according to your needs
- install and switch to a supported node.js version (automatically done via .nvmrc file)
`nvm install`
- install the required modules
`npm install`
- switch back to your system's default node.js version
`nvm deactivate`
- execute ninwa
`node ninwa.js`
`nvm run ninwa.js`
## systemd
**for security reasons it is highly recommended to not run ninwa with root permissions!**
- create a new system user
`useradd -r -s /usr/bin/nologin ninwa`
`useradd -U -r -s /usr/bin/nologin node`
- make your install of nvm available to the new user
`cp -R ~/.nvm /opt/nvm`
`chown -R node /opt/nvm`
- symlink the provided systemd-service file and modify it according to your needs
`ln -s /path/to/ninwa/ninwa.service /etc/systemd/system/ninwa.service`
`ln -s /opt/ninwa/ninwa.service /etc/systemd/system/ninwa.service`
- reload systemd-services
`systemctl daemon-reload`
