Seed Viewer

A simple NodeJS based app with an EJS frontend built as part of the participation in the #growlab contest.

How to install

This assumes you have phototimer setup and running on the same device. It is recommended to use pm2 to keep this app running. These steps are based on using a Raspberry Pi Zero.

#Install updates and Git
sudo apt update && sudo apt upgrade -qy
sudo apt install git -qy
#Create required directories and set permissions (adjust if necessary)
sudo mkdir /seed
sudo mkdir /seed/app
sudo chmod 777 /seed -R
#Install node 
cd /seed/app
wget -O - https://raw.githubusercontent.com/sdesalas/node-pi-zero/master/install-node-v14.10.0.sh | bash
node --version
#Install pm2
sudo npm install -g pm2
pm2 status
#If command fails, run `whereis pm2` and add the directory to PATH (e.g. `export PATH=$PATH:/opt/nodejs/bin/ && source ~/.bashrc`)
#Download and install app
cd /seed/app/
sudo git clone https://github.com/sam-perrin/seed-viewer
cd /seed/app/seed-viewer
sudo npm install

Run the app

The app requires an environment variable IMG_DIR to be set. This is the directory that phototimer is outputting images to. In my case this was /seed/images. Optionally you can pass in a PORT, by default this uses 3000.

IMG_DIR=/seed/images pm2 start /seed/app/seed-viewer/index.js --name seed-viewer
pm2 status
#You should see an entry named "seed-viewer" with the status of "running"

To enable this app to autostart on device reboot, run the following

pm2 startup
#Follow the directions outputted to setup pm2 startup
pm2 save
