This is a directory-first photo gallery website, optimised for running on low resource servers (especially on raspberry pi)
## Live Demo
Live Demo @ heroku: https://pigallery2.herokuapp.com/
- the demo page **first load** might take up **30s**: the time while the free webservice boots up

## 1. Getting started (also works on Raspberry Pi)
### 1.1 Run with Docker (recommended)
If you have `docker` and don't want to install all the dependencies, you can use one of our docker build.
For configuration and docker-compose files read more [here](docker/README.md) or check all builds: https://hub.docker.com/r/bpatrik/pigallery2/tags/
**Note**: You dont need to do the rest of the installation steps if you are using docker.
### 1.2 Direct Install
As an alternative, you can also directly install nodejs and the app and run it natively.
### 1.2.0 [Install NodeJs](https://nodejs.org/en/download/)
Download and extract
```bash
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs
```
Full node install on raspberry pi description: https://www.w3schools.com/nodejs/nodejs_raspberrypi.asp
### 1.2.1 Install PiGallery2
#### 1.2.1-a Install from release
```bash
cd ~
wget https://github.com/bpatrik/pigallery2/releases/download/1.7.0/pigallery2.zip
unzip pigallery2.zip -d pigallery2
cd pigallery2
npm install
```
#### 1.2.1-b Install from source
```bash
cd ~
wget https://github.com/bpatrik/pigallery2/archive/master.zip
unzip master.zip
cd pigallery2-master # enter the unzipped directory
npm install
npm build
```
**Note**: if you run `npm run create-release`, it creates a clean, minified, production ready version from the app in the `release` folder, that is ready to deploy.
**Note2**: you can use `npm run create-release -- --languages=fr,ro` to restrict building to the listed languages (english is added by default)
#### 1.2.2 Run PiGallery2
```bash
npm start
```
To configure it, run `PiGallery2` first to create `config.json` file, then edit it and restart.
The app has a nice UI for settings, you may use that too.
Default user: `admin` pass: `admin`
**Note**: First run, you might have file access issues and port 80 issue, see [#115](https://github.com/bpatrik/pigallery2/issues/115).
Running `npm start -- --Server-port=8080` will start the app on port 8080 that does not require `root`
Adding read/write permissions to all files can solve the file access issue `chmod -R o-w .`, see [#98](https://github.com/bpatrik/pigallery2/issues/98).
### 1.3 Advanced configuration
You can set up the app the following ways:
* Using the UI
* Manually editing the `config.json`
* Through switches
* Like: `node start -- --Server-port=3000 --Client-authenticationRequired=false`
* You can check the generated `config.json` for the config hierarchy
* Note: you can run the app to generate the config file only, by running `npm start -- --config-only`
* Through environmental variable
* like set env. variable `Server-port` to `3000`
### 1.4 Useful links/tips:
#### using nginx
It is recommended to use a reverse proxy like nginx before node
https://stackoverflow.com/questions/5009324/node-js-nginx-what-now
#### making https
With cerbot & nginx it is simple to set up secure connection. You have no excuse not doing so.
https://certbot.eff.org/
#### node install error:
If you get error during module installation, make sure you have everything to build node modules from source
```bash
apt-get install build-essential libkrb5-dev gcc g++
```
## 2. Translate the page to your own language
1. [Install Pigallery2](#111-b-install-from-source) from source (with the release it won't work)
2. add your language e.g: fr
```bash
npm run add-translation -- --fr
```
it creates a new `messages.fr.xls` file at `src/frontend/translate` folder,
it will already contain dummy translation with google translate.
3. 'fix' the dummy translation
4. test if it works:
build and start the app
```bash
npm install
npm start
```
5. (optional) create a pull request at github to add your translation to the project.
**Note**: you can also build your own release with as described in [1.1.1-b Install from source](#111-b-install-from-source);

* rendering photos on demand (on scroll)
* **On the fly thumbnail generation** in several sizes
* prioritizes thumbnail generation (generating thumbnail first for the visible photos)
* saving generated thumbnails to TEMP folder for reuse
* supporting multi-core CPUs
* supporting hardware acceleration ([sharp](https://github.com/lovell/sharp) and [gm](https://github.com/aheckmann/gm) as optional and JS-based [Jimp](https://github.com/oliver-moran/jimp) as fallback)

* **Two modes: SQL database and no-database mode**
* both modes supports
* user management
* password protection can be disabled/enabled

* uses ffmpeg and ffprobe to generate video thumbnails
* Dockerized
* **Markdown based blogging support** - `future plan`
* you can write some note in the blog.md for every directory
* bug free :) - `In progress`
## 4. Suggest/endorse new features
You are welcome to suggest new features to the application via [github issues](https://github.com/bpatrik/pigallery2/issues).
I cannot garantie any dealine with the development of a new feature. (I usually fix bugs within week/weeks.)
I will give a higher priority to a feature that has more 'likes' (i.e.: `+1`-s or thumbs ups) on it.
## 5. Known errors
* EXIF orientation tag:
* There is no nice way to handle EXIF orientation tag properly.
The page handles these photos, but might cause same error in the user experience (e.g.: the pages loads those photos slower. See issue [#11](https://github.com/bpatrik/pigallery2/issues/11))
* Video support on weak servers (like raspberry pi) with low upload rate
* video playback may use up too much resources and the server might not response for a while. A solution might be to down scale / convert the video files to lower bitrate.
