# shinyCluster
`shinyCluster` is a simple Node.js module for launching a single R shiny application in a cluster of workers and keep track of sessions.
This is an experimental project. Please send me a feedback if you find this script useful.
# Other ways
* For production: use the official shiny-server or [shiny-server pro](https://www.rstudio.com/products/shiny-server-pro/).
* Load balancing: [A Shiny-app Serves as Shiny-server Load Balancer](http://withr.me/a-shiny-app-serves-as-shiny-server-load-balancer/)
# Usage
## Prerequisite
* [nodejs + npm](https://nodejs.org/download/)
* [R](http://www.r-project.org/)
* [R package shiny](https://cran.r-project.org/web/packages/shiny/index.html)
## Install
```{sh}
npm install @fxi/shiny-cluster --save
```
## Example
### Launch the default app
```{js}
var shinyCluster= require('@fxi/shiny-cluster');
/**
* Launch a simple shiny app ( located in `./example` ),
* using 3 workers and
* listen on port 3456
*/
shinyCluster.run({
path : "./example/app.R" // path to directory of shiny app or app.R file
concurency : 3,
port : 3456
});
```
### Launch your app
```{js}
var shinyCluster= require('@fxi/shiny-cluster');
/**
* Launch your shiny app
* located here `/home/john/myShinyApp/app.R`,
* using 10 workers and
* listen on port 3434
*/
shinyCluster.run({
path : '/home/john/myShinyApp' ,
concurency : 10,
port : 3434
});
```

# Change logs
0.0.6 -> 0.0.8
- wait on shiny app to be ready using stderr output (not really clean)
- setup config: timeoutConnect, timeoutListen, nTry
- set option for host
0.0.5 -> 0.0.6
- wait on shiny port to be available using net.connect
- better error handling
0.0.2 -> 0.0.5
- paths issues
- better example
0.0.1 -> 0.0.2
- build a node module
- use sticky-cluster
- simplify everything
