### Shiny server set-up
On an Ubuntu GNU/Linux system, install R (>4.0.0) and follow [this guide](https://rstudio.com/products/shiny/download-server/ubuntu/)
```console
$ sudo apt install r-base
$ sudo su - -c "R -e \"install.packages('shiny', repos='https://cran.rstudio.com/')\""
```
Follow instructions in [the Shiny-server wiki](https://github.com/rstudio/shiny-server/wiki/Building-Shiny-Server-from-Source).
Run and test your Shiny-server implementation:
```console
$ sudo systemctl start shiny-server
```
For troubleshooting, see the [Shiny-server administrator's guide](https://docs.rstudio.com/shiny-server/).
### Required packages
Install R package dependencies
```console
$ sudo apt install build-essential libfontconfig1-dev libcairo2-dev gfortran libcurl4-openssl-dev libssl-dev libgit2-dev libudunits2-dev libxt-dev gdal-bin libgdal-dev
```
Install R packages:
```console
$ sudo su -
# R -e "install.packages(c('RMariaDB', 'DBI', 'pool', 'dplyr', 'ggplot2', 'DT', 'devtools', 'shinyjs', 'openxlsx', 'leaflet', 'wesanderson', 'ggthemes', 'ggsci', 'cowplot', 'plotly', 'shinydashboard', 'shinyWidgets', 'dbplyr', 'svglite', 'Cairo', 'jsonlite', 'raster', 'sf', 'readr', 'shinydisconnect'), repos='https://cran.rstudio.com/')"
```
Alternative to sf: `exactextractr` and `geojsonsf` (more efficient than sf_read).
### Run the applications
Enter the database name, host, username and password in the two `Global.R` files.
Change file permissions recursively for www folders in Downloads and Visualise
Test application in R:
```console
$ R
> library(shiny)
> runApp(/srv/Shiny/Download/, launch.browser = F)
```
