Urocissa

Urocissa is a self-hosted gallery designed to serve massive collections, capable of handling millions of images and videos. It is built using Rust and Vue.

Motivation

The goal of this project is to efficiently serve one million photos on a 4 GB RAM server, providing smooth scrubbable scrolling, infinite photo streams, and instant search and selection, without waiting for the entire database to load in the browser.

Demo

You can explore the features of Urocissa through the following demos:

Standard Demo

https://demo.photoserver.tw
Password: password

This demo showcases the typical usage of Urocissa, allowing you to experience its core features and user interface.

One-Million-Photo Demo

https://demo-million.photoserver.tw
Password: password

This demo demonstrates Urocissa's ability to manage 1,000,000 photos, showcasing the power and scalability of Urocissa. Since I don't have access to a million unique images, the photos in this demo are replaced with placeholders.

Both demos are currently in read-only mode, and uploading files or editing tags is not permitted at this time.

Features

• Blazing Fast Performance: Indexing photos with a pure Rust crate. Instantly serve, search, and filter one million photos in under a second using an in-memory cached database.

• Memory Efficient: Even with the entire database cached in memory, both the standard demo and the one-million-photo demo can still run seamlessly on a single server with just 4 GB of RAM.

• Infinite Photo Stream: Endless scrolling without pagination. No lazy loading is needed. Urocissa uses advanced virtual scrolling to serve one million photos, overcoming the DOM height limit of 33,554,400px (see TanStack/virtual#616).

• Instant Select All: Select all photos instantly without loading the entire database.

• Responsive Layout: Adaptive design that allows browsing on mobile devices.

• Instant Data Search: Search data using boolean operators such as 'and', 'or', or 'not'. You can find examples of search queries here.

Limitations

1. Early Stage Development: The app is still in its very early development phase. Many features are incomplete, and there are no automated tests. Additionally, Urocissa is currently optimized for Chrome and Firefox on Windows and Android, but it may encounter issues for browsers on iOS or Linux.

2. No AI Face Recognition: The app currently does not support AI-based face recognition.

3. Single User Only: Only supports personal use and cannot create multiple user accounts.

Steps to Set Up and Use the App

Follow these instructions to set up and run the Urocissa app.

2. Install Dependencies

Make sure the following software is installed on your system:

• ffmpeg: Install via APT on Ubuntu:

  sudo apt update && sudo apt install -y ffmpeg

• Rust: Install Rust using the official installer:

  curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y
  source $HOME/.cargo/env

• npm (Node.js): Install Node.js (with npm) from NodeSource:

  curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
  sudo apt install -y nodejs

3. Configure Backend Settings

1. Navigate to the backend directory:

   cd ./Urocissa/gallery-backend

2. Copy the default config file and fill in the necessary settings:

   cp config.default.json config.json
   cp Rocket.default.toml Rocket.toml

   config.json:

   {
     "password": "your_password_here",
     "readOnlyMode": false,
     "syncPath": ["./upload"],
     "disableImg": false,
     "discordHookUrl": null
   }

   Explanation:

   • password: Your password for the app.
   • readOnlyMode: Set to false to allow changes.
   • syncPath: List of directories that the app will watch for new or modified photos.
   • disableImg: For debugging purposes (leave it as false).
   • discordHookUrl: (Optional) Fill in your Discord webhook URL to receive error notifications.

   Rocket.toml:

   • port: Default is 4000. You can change this to your desired port number.

4. Build the Backend

Navigate to gallery-backend and build the backend using Cargo:

cargo build --release

---

5. Configure Frontend Settings

1. Navigate to the gallery-frontend directory:

   cd ./Urocissa/gallery-frontend

2. Copy the default frontend config file:

   cp config.default.ts config.ts

   Note: The config.ts file contains advanced settings. You can leave it unchanged unless you need to customize it.

---

6. Install Frontend Dependencies

In the gallery-frontend directory, run:

npm install

---

7. Build the Frontend

Build the frontend by running:

npm run build

---

8. Run the Application

Navigate to the gallery-backend directory and run the following command to start the app:

cargo run --release

You can now access the app via http://127.0.0.1:4000 or http://127.0.0.1:<your_port> if you configured a custom port in Rocket.toml.
