Prayer timetable

** Major update **: new code is halved and as such twice as efficient; also restructured to use redux and styled-components. For old version with sass, look for 0.4.0.

Muslim prayer timetable app for deployment on Raspberry Pi. It is meant to be used on public displays to show your local community's prayer times. Can be used in masjids, mosques or even at home. Optimised for Full HD screens. Made using React and Neutrino JS, with Moment JS for time manipulation. Please note that this is in ~~alpha~~ beta stage and built specifically for my own needs.

This software is provided as-is, with no warranty of any kind. I provide it for free and do not expect and/or ask for any compensation. What's more, I will help you setup your own presentation screen and even install for free, but you will cover the postal bills in case you send me your own Raspberry Pi for setup.

Instructions on full deployment coming soon, for now you're on your own. :)

Yarn

Although you can use npm command for all the steps, I recommend using Yarn package. It significantly speeds up the compilation process on Rasperry Pi.

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update && sudo apt-get install yarn

Quick Start

Standalone app:

First clone the repo:

git clone https://gitlab.com/ench0/prayer-timetable-react

cd prayer-timetable-react 

Second, get the packages:

yarn

or

npm install

Bootstrap (check Settings file section below):

yarn setup:default

To start the app, use:

yarn start

or

npm run start

Aceess the app via http://localhost:5000/

To build static files (html + css + image) use:

yarn build

or

npm run build

Files are placed in /build folder.

As module (WIP):

import timetable from 'prayer-timetable-react'

Settings files

There are 4 files that need to be placed in 'src/config' folder, used to define all aspects of the app.

To use default settings (offline app, controled through settings.json file), while inside the prayer-timetable-react folder (check above for info on cloning) run

yarn setup:default

or if you are on Powershell:

yarn setup:default:win

That will create 4 files needed for the operation. Check and change them as needed.

The files are:

** settings.json **: settings file

** timetable.json **: timetable file

** theme.json **: theme file

** logo.svg **: logo file

These are the options available in aforementioned settings file:

title: obviously title of your organisation.

lang: not implemented yet.

online: if you do not want to fetch the contents from your own API but rather do it through the config file, leave this at false.

url: { settings: API link to your settings timetable: if your timetable keeps changing often, use this for the API of your timetable

announcement: message shown as a title in bottom message area

text: en: English text for message area. ar: Arabic text for message area.

hijrioffset: if you need to adjust your Hijri date by +- 1 or 2 days, use this option.

jummuahtime: time for Jummuah prayer.

taraweehtime: time of Taraweeh prayer.

jamaahmethods: 6 methods of calculation, can be: fixed (fixed prayer time), afterthis (hr/mins after the adhan), beforenext (hr/mins before next adhan), joined (hr/mins after previous adhan).

jamaahoffsets: hrs/mins to match the above methods.

labels: not fully implemented yet.

jummuah, taraweeh, prayer, adhan, iqamah, prepare, ramadancountdown, names: [Fajr Shurooq Dhuhr Asr Maghrib Isha]

updated: automatic date in Unix format picked from your own API; date of this settings update.

join: optional boolean value to decide whether maghrib and isha prayers should be joined/prayed together.

Timetable File

Typically, you will have your timetable file in json format and import/conver to object such as this:

import timetable from './timetable.json'

It is structured as follows:

{
    "1": {
        "1": [[6,43],[8,37],[12,30],[14,3],[16,19],[18,7]],
        "2": [[6,43],[8,37],[12,31],[14,3],[16,20],[18,8]],
        "3": [[6,43],[8,37],[12,31],[14,4],[16,22],[18,9]],
        ...
    }
...
}

Starts with month (first "1"), followed by day in a month ("1", "2", "3", ...). Every day contains array of six sub-arrays with [hour:minute] (no zero prepend) displayed inside.

Timetable file format used by lib here. Or use examples from other cities to figure out the JSON format.

Quick Raspberry Pi Setup (WIP)

First, get latest version of node:

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -

sudo apt-get install -y nodejs

Optional:

sudo apt-get install -y build-essential

Second, create autostart link:

mkdir ~/.config/autostart

nano ~/.config/autostart/autoChromium.desktop

Paste the following:

[Desktop Entry]
Type=Application
Exec=/usr/bin/chromium-browser --noerrdialogs --disable-session-crashed-bubble --disable-infobars --incognito --kiosk file:///home/pi/prayer-timetable-react/build/index.html
Hidden=false
X-GNOME-Autostart-enabled=true
Name[en_US]=AutoChromium
Name=AutoChromium
Comment=Start Chromium when GNOME starts

Third, edit boot config to enable vertical display:

sudo nano /boot/config.txt

Add this line to the end of the file:

display_rotate=3

Fourth, edit this file to disable the screensaver:

sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

This should be pasted in (and other content removed by ctrl < k >):

@lxpanel --profile LXDE-pi
@pcmanfm --desktop --profile LXDE-pi
@point-rpi
@xset s noblank
@xset s off
@xset -dpms
@unclutter -display :0 -idle 3 -root -noevents

Last line above removes the mouse cursor when idle. Optionally, remove the mouse cursor completely (warning! invisible cursor):

sudo nano /etc/lightdm/lightdm.conf


[SeatDefaults]
#type=xlocal
#xdg-seat=seat0
#pam-service=lightdm
#pam-autologin-service=lightdm-autologin
#pam-greeter-service=lightdm-greeter
#xserver-command=X -s dpms
xserver-command=X -s dpms -nocursor
#xserver-layout=
...
autologin-user=pi

Lastly, follow the quickstart from the beginning of this file.
