# shinymisc: Miscellaneous educational shiny apps
The `shinymisc` package provides a set of apps that are useful for beginner,
intermediate, and advanced `shiny` developers to explore different features of
the `shiny` framework and philosophy.
## Installation
```{r, eval=FALSE}
devtools::install_github("Nelson-Gon/shinymisc")
```
## Loading the package
```{r}
library(shinymisc)
```
## Exploring included apps
`shinymisc` contains a number of apps that demonstrate different concepts.
To view an app, run the following:
```{r, eval=FALSE}
run_app(app_name = "theming")
```
* [Plot theming](https://github.com/Nelson-Gon/shinymisc/blob/main/R/theming.R)
This app takes a fairly advanced approach at demonstrating how one can combine different `shiny` principles to achieve plot customization. This was built to help me figure out how to best choose themes from different packages. In particular, I wanted to do this even if the package was not on the `search` list.
This app explores concepts of reactivity, modularization, testing, and scaling
in general.
```{r, eval=FALSE}
run_app("theming")
```
* [Sample App](https://nelson-gon.shinyapps.io/sampleapp)
This app aims to do something fairly simple. It takes input data, allows user confirmation and finally prints the data entered. It was built as part of a blog I wrote to highlight `shiny` features like reactivity, observers, and performance improvements. This blog post is available at https://nelson-gon.github.io/12/12/2021/shiny-reactivity/. You can view the source code [here](https://github.com/Nelson-Gon/shinymisc/blob/main/R/sample_app.R).
* [List Package Functions](https://github.com/Nelson-Gon/shinymisc/blob/main/R/list_functions.R)
This app was written as I tried to play around with namespaces and accessing functions in a package. In particular, I wanted to be able to load a function from a package without necessarily loading said package first. This is important because sometimes loading a package may result in function conflicts causing further debugging work.
* [Shiny Modules](https://github.com/Nelson-Gon/shinymisc/blob/main/R/modular_app.R)
This simple app explores the use of shiny [modules](https://shiny.rstudio.com/articles/modules.html). This is aimed at demonstrating how one can reuse code across different places within the app without copying and pasting the same code over and over again.
The app also shows how to use some different layouts.
* [More Modules](https://github.com/Nelson-Gon/shinymisc/blob/main/R/more_modules.R)
Another module based app that also includes some basic plotly plots. This app was
created as a way for me to debug some issue with `shiny`'s module system and the
use of `update*` functions. Specifically, sometimes, it is possible that `update*`
functions may not work as expected/intended. Unfortunately this is not readily
visible in this app. Hopefully with more exploration, one could meet this pitfall
and play with ways around it.
Keep building,
Nelson
