1. Getting started (also works on Raspberry Pi)

1.1 Install and Run with Docker (recommended)

Docker with docker-compose is the offitial 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 or check all builds: https://hub.docker.com/r/bpatrik/pigallery2/tags/

1.2 Direct Install (if you are familiar with nodejs and building npm packages from source)

As an alternative, you can also directly install nodejs and the app and run it natively.

1.2.0 Install NodeJs

Download and extract

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

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.

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 mashine 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

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. 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.

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.

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

apt-get install build-essential  libkrb5-dev gcc g++

2. Translate the page to your own language

Install Pigallery2 from source (with the release it won't work)
add your language e.g: fr
```
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.
'fix' the dummy translation
test if it works: build and start the app
```
npm install
npm run build
npm start
```
(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;

4. Suggest/endorse new features

You are welcome to suggest new features to the application via github 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)
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.
