Food Manager

About

I created this tool for my parents so they can keep track of all the food stuffs they have in their house as they always seemed to forget what they have and ended up buying lots of extra things. The idea was to have a self-hosted website they could access at any point from their tablets or computers to check for anything that's about to expire or if they need to buy anything extra.

The whole UI was designed to be simple to use and clean, and accessible on large screens, as well as tablets. I have not implemented a proper view for mobile as this wasn't a requirement they needed, but I welcome any pull requests to add this.

This project is built using SvelteKit and Prisma (using Sqlite).

Setup

Run npm i first to install necessary dependencies

To initialize the database, run: npm run init-db

To view a development preview, run npm run dev

To build a production deployment, run npm run build

Deploying to Pi

Prerequisites

• The Pi OS has to be 64 bit
• Install nodejs version v18.18 using nvm

Building

1. Delete the .sveltekit and build directories in the project
2. npm run build
3. Copy over the build directory, package.json, and package-lock.json over to the Pi
4. Run npm i --production on the Pi
5. Move over the prisma directory inside the build directory on the Pi
   1. Example path: app/build/prisma
6. Run npx prisma generate --schema build/prisma/schema.prisma on the Pi
7. Now it's ready to run with node build

Running on Another Port

The ORIGIN and PORT environment variables can be used to change the port it runs on. For example, using port 1234:

ORIGIN=http://localhost:1234 PORT=1234 node build

Note that localhost can be swapped out for the hostname.local URL instead. See here for details on how to access the pi via the hostname up and running.

Running on Port 80 in the Background

Firstly, iptables is required for this, so install it with apt-get.

The script to run the app in the background on port 80 is the following:

#!/bin/sh
sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3000
ORIGIN=http://localhost/ PORT=3000 nohup node build &
