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 [Install and Run with Docker (recommended)](docker/README.md)

[Docker](https://www.docker.com/) with [docker-compose](https://docs.docker.com/compose/) is the official and recommend way of installing and running *Pigallery2*.
It contains all necessary dependencies, auto restarts on reboot, supports https, easy to upgrade to newer versions.
For configuration and docker-compose files read more [here](docker/README.md) or check all builds: https://hub.docker.com/r/bpatrik/pigallery2/tags/



### 1.2 Direct Install (if you are familiar with Node.js and building npm packages from source)
As an alternative, you can also directly install Node.js and the app and run it natively. 
### 1.2.0 [Install Node.js](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/1.8.0/pigallery2.zip
unzip pigallery2.zip -d pigallery2
cd pigallery2
npm install
```
#### 1.2.1-b Install from source

**Note:** A build requires a machine with around 2GB or memory.


```bash
cd ~
wget https://github.com/bpatrik/pigallery2/archive/master.zip
unzip master.zip
cd pigallery2-master # enter the unzipped directory
npm install
npm run build
```

**Note**: It is recommended to create a release version with `npm run create-release` on a more powerful machine and deploy that to you server.

**Note**: 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).

##### 1.2.2.1 Run on startup
You can run the app up as a service to run it on startup. Read more at [#42](https://github.com/bpatrik/pigallery2/issues/42#issuecomment-458340945)

### 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
 * Through environmental variable
   * like set env. variable `Server-port` to `3000`   

Full list of configuration options are available at the [MANPAGE.md](MANPAGE.md).

### 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](#121-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 run build
   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](#121-b-install-from-source);

## 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 guarantee any deadline with the development of a new feature. (I usually fix bugs within a 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:
  *  Some photos code the orientation tag and with/height in a less conventional format, like the "duck photo" in [#19](https://github.com/bpatrik/pigallery2/issues/19). 
After Browsers support orientation tag natively [#172](https://github.com/bpatrik/pigallery2/issues/172), I could not find a solution for that. 
* 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. Enable video transcoding in the app, to transcode the videos to lover bitrate.
