1. Getting started (on Raspberry Pi)

1.1 Direct Install

1.1.0 Install NodeJs

Download and extract

curl -sL https://deb.nodesource.com/setup_10.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

1.1.1 Install PiGallery2

1.1.1-a Install from release

cd ~
wget https://github.com/bpatrik/pigallery2/releases/download/1.7.0/pigallery2.zip
unzip pigallery2.zip -d pigallery2
cd pigallery2
npm install

1.1.1-b Install from source

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

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. Note: you can use npm run create-release -- --languages=fr,ro to restrict building to the listed languages (english is added by default)

1.1.2 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

1.2 Run with Docker

If you have docker and don't want to install all the dependencies, use this:

docker run \
   -p 80:80 \
   -e NODE_ENV=production \
   -v <path to your config file folder>/config.json:/pigallery2-release/config.json \
   -v <path to your db file folder>/sqlite.db:/pigallery2-release/sqlite.db \
   -v <path to your images folder>:/pigallery2-release/demo/images \
   -v <path to your temp folder>:/pigallery2-release/demo/TEMP \
   bpatrik/pigallery2:1.7.0-stretch

Make sure that a file at <path to your config file folder>/config.json and sqlite.db files exists before running it.

You do not need the <path to your db file folder>/sqlite.db line if you don't use the sqlite database.

After the container is up and running, you go to http://localhost and log in with user: admin pass: admin and set up the page in the settings.

All docker builds: https://hub.docker.com/r/bpatrik/pigallery2/tags/

Note: You dont need to do the installation steps if you are using docker.

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 backend/index.js --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

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

1. Install Pigallery2 from source (with the release it won't work)
2. add your language e.g: fr

   npm run add-translation -- --fr
   

   it creates a new messages.fr.xls file at 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

   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;

  • 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. 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. A solution might be to down scale / convert the video files to lower bitrate.
