 Description: Makes it incredibly easy to build interactive web
     applications with R. Automatic "reactive" binding between inputs and
     outputs and extensive prebuilt widgets make it possible to build
     beautiful, responsive, and powerful applications with minimal effort.

-# shiny (development version)
-
-## New features
-
-* The `icon` argument of `updateActionButton()`/`updateActionLink()` nows allows values other than `shiny::icon()` (e.g., `fontawesome::fa()`, `bsicons::bs_icon()`, etc). (#4249)
-
-## Bug fixes
-
-* `updateActionButton()`/`updateActionLink()` now correctly renders HTML content passed to the `label` argument. (#4249)
-
-* Fixed an issue where `updateSelectizeInput(options = list(plugins="remove_button"))` could lead to multiple remove buttons. (#4275)
-
-## Changes
-
-* The return value of `actionButton()`/`actionLink()` changed slightly: `label` and `icon` are wrapped in an additional HTML container element. This allows for: 1. `updateActionButton()`/`updateActionLink()` to distinguish between the `label` and `icon` when making updates and 2. spacing between `label` and `icon` to be more easily customized via CSS. 
-
-# shiny 1.11.1
-
-This is a patch release primarily for addressing the bugs introduced in v1.11.0.
-
-## Bug fixes
-
-* Fixed an issue where `InputBinding` implementations that don't pass a value to their `subscribe` callback were no longer notifying Shiny of input changes. (#4243)
-
-* `updateActionButton()` and `updateActionLink()` once again handle `label` updates correctly. (#4245)
-
-# shiny 1.11.0
-
-## Improvements
-
-* When auto-reload is enabled, Shiny now reloads the entire app when support files, like Shiny modules, additional script files, or web assets, change. To enable auto-reload, call `devmode(TRUE)` to enable Shiny's developer mode, or set `options(shiny.autoreload = TRUE)` to specifically enable auto-reload. You can choose which files are watched for changes with the `shiny.autoreload.pattern` option. (#4184)
-
-* When busy indicators are enabled (i.e., `useBusyIndicators()`), Shiny now:
-    * Shows a spinner on recalculating htmlwidgets that have previously rendered an error (including `req()` and `validate()`). (#4172)
-    * Shows a spinner on `tableOutput()`. (#4172)
-    * Places a minimum height on recalculating outputs so that the spinner is always visible. (#4172)
-
-* Shiny now uses `{cli}` instead of `{crayon}` for rich log messages. (thanks @olivroy, #4170)
-
-* `renderPlot()` was updated to accommodate changes in ggplot2 v4.0.0. (#4226)
-
-* When adding the new tab via `insertTab()` or `bslib::nav_insert()`, the underlying JavaScript no longer renders content twice. (#4179)
-
-## New features
-
-* `textInput()`, `textAreaInput()`, `numericInput()` and `passwordInput()` all gain an `updateOn` option. `updateOn = "change"` is the default and previous behavior, where the input value updates immediately whenever the value changes. With `updateOn = "blur"`, the input value will update only when the text input loses focus or when the user presses Enter (or Cmd/Ctrl + Enter for `textAreaInput()`). (#4183)
-
-* `textAreaInput()` gains a `autoresize` option, which automatically resizes the text area to fit its content. (#4210)
-
-* The family of `update*Input()` functions can now render HTML content passed to the `label` argument (e.g., `updateInputText(label = tags$b("New label"))`). (#3996)
-
-* `ExtendedTask` now catches synchronous values and errors and returns them via `$result()`. Previously, the extended task function was required to always return a promise. This change makes it easier to use `ExtendedTask` with a function that may return early or do some synchronous work before returning a promise. (#4225)
-
-* The `callback` argument of Shiny.js' `InputBinding.subscribe()` method gains support for a value of `"event"`. This makes it possible for an input binding to use event priority when updating the value (i.e., send immediately and always resend, even if the value hasn't changed). (#4211)
-
-## Changes
-
-* Shiny no longer suspends input changes when _any_ `<input type="submit">` or `<button type="submit">` is on the page. Instead, it now only suspends when a `submitButton()` is present. If you have reason for creating a submit button from custom HTML, add a CSS class of `shiny-submit-button` to the button. (#4209)
-
-* Shiny's JavaScript assets are now compiled to ES2021 instead of ES5. (#4066)
-
-* Upgraded jQuery from 3.6.0 to 3.7.1. (#3969)
-
-* Updated jQuery UI from 1.13.2 to 1.14.1. (#4175)
-
-## Bug fixes
-
-* The Shiny Client Console (enabled with `shiny::devmode()`) no longer displays duplicate warning or error message. (#4177)
-
-* Synchronous errors that occur inside a `ExtendedTask` no longer stop the session. (#4225)
-
-* Calling `removeModal()` immediately after `showModal()` no longer fails to remove the modal (this would sometimes happen if the remove message was received while the modal was in the process of being revealed). (#4173)
-
-* `runExample("08_html")` now (correctly) requests to 'shiny.min.css', eliminating a network request failure. (#4220)
-
-* `shiny::shinyAppTemplate()` no longer errors without a call to `library(shiny)`. (#3870)
-

-## New features and improvements
-
-* When busy indicators are enabled (i.e., `useBusyIndicators()` is in the UI), Shiny now:
-    * Shows the pulse indicator when dynamic UI elements are recalculating and no other spinners are visible in the app. (#4137)
-    * Makes the pulse indicator slightly smaller by default and improves its appearance to better blend with any background. (#4122)
-
-* Improve collection of deep stack traces (stack traces that are tracked across steps in an async promise chain) with `{coro}` async generators such as `{elmer}` chat streams. Previously, Shiny treated each iteration of an async generator as a distinct deep stack, leading to pathologically long stack traces; now, Shiny only keeps/prints unique deep stack trace, discarding duplicates. (#4156)
-
-* Added an example to the `ExtendedTask` documentation. (@daattali #4087)
-
-## Bug fixes
-
-* Fixed a bug in `conditionalPanel()` that would cause the panel to repeatedly show/hide itself when the provided condition was not boolean. (@kamilzyla, #4127)
-
-* Fixed a bug with `sliderInput()` when used as a range slider that made it impossible to change the slider value when both handles were at the maximum value. (#4131)
-
-* `dateInput()` and `dateRangeInput()` no longer send immediate updates to the server when the user is typing a date input. Instead, it waits until the user presses Enter or clicks out of the field to send the update, avoiding spurious and incorrect date values. Note that an update is still sent immediately when the field is cleared. (#3664)
-
-* Fixed a bug in `onBookmark()` hook that caused elements to not be excluded from URL bookmarking. (#3762)
-
-* Fixed a bug with stack trace capturing that caused reactives with very long async promise chains (hundreds/thousands of steps) to become extremely slow. Chains this long are unlikely to be written by hand, but `{coro}` async generators and `{elmer}` async streaming were easily creating problematically long chains. (#4155)
-
-* Duplicate input and output IDs -- e.g. using `"debug"` for two inputs or two outputs -- or shared IDs -- e.g. using `"debug"` as the `inputId` for an input and an output -- now result in a console warning message, but not an error. When `devmode()` is enabled, an informative message is shown in the Shiny Client Console. We recommend all Shiny devs enable `devmode()` when developing Shiny apps locally. (#4101)
-
-* Updating the choices of a `selectizeInput()` via `updateSelectizeInput()` with `server = TRUE` no longer retains the selected choice as a deselected option if the current value is not part of the new choices. (@dvg-p4 #4142)
-
-* Fixed a bug where stack traces from `observeEvent()` were being stripped of stack frames too aggressively. (#4163)
-
-# shiny 1.9.1
-
-## Bug fixes

-* Fixed a bug introduced in v1.9.0 where the boundaries of hover/click/brush regions on plots were being incorrectly scaled when browser zoom was used. (#4111)
-
-# shiny 1.9.0
-
-## New busy indication feature
-
-Add the new `useBusyIndicators()` function to any UI definition to:
-  1. Add a spinner overlay on calculating/recalculating outputs.
-  2. Show a page-level pulsing banner when Shiny is busy calculating something (e.g., a download, side-effect, etc), but no calculating/recalculating outputs are visible.
-
-In a future version of Shiny, busy indication will be enabled by default, so we encourage you to try it out now, provide feedback, and report any issues.
-
-In addition, various properties of the spinners and pulse can be customized with `busyIndicatorOptions()`. For more details, see `?busyIndicatorOptions`. (#4040, #4104)
-
-## New features and improvements
-
-* The client-side TypeScript code for Shiny has been refactored so that the `Shiny` object is now an instance of class `ShinyClass`. (#4063)
-
-* In TypeScript, the `Shiny` object has a new property `initializedPromise`, which is a Promise-like object that can be `await`ed or chained with `.then()`. This Promise-like object corresponds to the `shiny:sessioninitialized` JavaScript event, but is easier to use because it can be used both before and after the events have occurred. (#4063)
-
-* Output bindings now include the `.recalculating` CSS class when they are first bound, up until the first render. This makes it possible/easier to show progress indication when the output is calculating for the first time. (#4039)
-
-* A new `shiny.client_devmode` option controls client-side devmode features, in particular the client-side error console introduced in shiny 1.8.1, independently of the R-side features of `shiny::devmode()`. This usage is primarily intended for automatic use in Shinylive. (#4073)
-
-* Added function `reactlogAddMark()` to programmatically add _mark_ed locations in the reactlog log without the requirement of keyboard bindings during an idle reactive moment. (#4103)
-
-## Bug fixes
-
-* `downloadButton()` and `downloadLink()` are now disabled up until they are fully initialized. This prevents the user from clicking the button/link before the download is ready. (#4041)
-
-* Output bindings that are removed, invalidated, then inserted again (while invalidated) now correctly include the `.recalculating` CSS class. (#4039)
-
-* Fixed a recent issue with `uiOutput()` and `conditionalPanel()` not properly lower opacity when recalculation (in a Bootstrap 5 context). (#4027)
-
-* Image outputs that were scaled by CSS had certain regions that were unresponsive to hover/click/brush handlers. (#3234)
-
-# shiny 1.8.1.1
-
-* In v1.8.1, shiny.js starting throwing an error when input/output bindings have duplicate IDs. This error is now only thrown when `shiny::devmode(TRUE)` is enabled, so the issue is still made discoverable through the JS error console, but avoids unnecessarily breaking apps that happen to work with duplicate IDs. (#4019)
-
-# shiny 1.8.1
-
-## New features and improvements
-
-* Added `ExtendedTask`, a new simple way to launch long-running asynchronous tasks that are truly non-blocking. That is, even _within_ a session, an `ExtendedTask` won't block the main thread from flushing the reactive graph (i.e., UI updates won't be blocked). `ExtendedTask` pairs nicely with new `bslib::input_task_button()` and `bslib::bind_task_button()` functions, which help give user feedback and prevent extra button clicks. (#3958)
-
-* Added a JavaScript error dialog, reporting errors that previously were only discoverable by opening the browser's devtools open. Since this dialog is mainly useful for debugging and development, it must be enabled with `shiny::devmode()`. (#3931)
-
-* `runExample()` now uses the `{bslib}` package to generate a better looking result. It also gains a `package` argument so that other packages can leverage this same function to run Shiny app examples. For more, see `?runExample`. (#3963, #4005)
-
-* Added `onUnhandledError()` to register a function that will be called when an unhandled error occurs in a Shiny app. Note that this handler doesn't stop the error or prevent the session from closing, but it can be used to log the error or to clean up session-specific resources. (thanks @JohnCoene, #3993)
-
-## Changes
-
-* `renderDataTable()`/`dataTableOutput()` are officially deprecated in favor of [their `{DT}` equivalents](https://rstudio.github.io/DT/shiny.html). Migrating to `{DT}`, in most cases, just requires changing `renderDataTable()` to `DT::renderDT()` and `dataTableOutput()` to `DT::DTOutput()`. Also, to promote migration, when a recent version of `{DT}` is available, `renderDataTable()`/`dataTableOutput()` now automatically use their `{DT}` equivalent (and provide a message that they are doing so). If this happens to degrade an existing app, set `options(shiny.legacy.datatable = TRUE)` to get the old (i.e., non-`{DT}`) implementation. (#3998)
-
-* Both `conditionalPanel()` and `uiOutput()` are now styled with `display: contents` by default in Shiny apps that use Bootstrap 5. This means that the elements they contain are positioned as if they were direct children of the parent container holding the `conditionalPanel()` or `uiOutput()`. This is probably what most users intend when they use these functions, but it may break apps that applied styles directly to the container elements created by these two functions. In that case, you may include CSS rules to set `display: block` for the `.shiny-panel-conditional` or `.shiny-html-output` classes. (#3957, #3960)
-
-## Bug fixes
-
-* Notifications are now constrained to the width of the viewport for window widths smaller the default notification panel size. (#3949)
-
-* Fixed #2392: `downloadButton()` now visibly returns its HTML tag so that it renders correctly in R Markdown and Quarto output. (Thanks to @fennovj, #2672)
-
-* Calling `updateSelectizeInput()` with `choices` and `selected` now clears the current selection before updating the choices and selected value. (#3967)
-
-* Loading a Shiny app in a package-like directory will no longer warn if autoloading is disabled by the presence of an `R/_disable_autoload.R` file. (Thanks to @krlmlr and @tanho63, #3513)
-
-# shiny 1.8.0
-
-## Breaking changes
-
-* Closed #3899: The JS function `Shiny.bindAll()` is now asynchronous. This change is driven by the recent push toward making dynamic UI rendering asynchronous, which is necessary for [shinylive](https://shinylive.io/r) (and should've happened when it was first introduced in Shiny v1.7.5). The vast majority of existing `Shiny.bindAll()` uses should continue to work as before, but some cases may break if downstream code relies on it being synchronous (i.e., blocking the main thread). In this case, consider placing any downstream code in a `.then()` callback (or `await` the result in a `async` function). (#3929)
-  * Since `renderContent()` calls `bindAll()` (after it inserts content), it now returns a `Promise<void>` instead of `void`, which can be useful if downstream code needs to wait for the binding to complete.
-
-## New features and improvements
-
-* Updated `selectizeInput()`'s selectize.js dependency from v0.12.4 to v0.15.2. In addition to many bug fixes and improvements, this update also adds several new [plugin options](https://selectize.dev/docs/demos/plugins). (#3875)
-
-* Shiny's CSS styling (for things like `showNotification()`, `withProgress()`, `inputPanel()`, etc.), has been updated with `{bslib}`'s upcoming CSS-only dark mode feature in mind. (#3882, #3914)
-
-* Default styles for `showNotification()` were tweaked slightly to improve accessibility, sizing, and padding. (#3913)
-
-* Shiny inputs and `{htmlwidgets}` are no longer treated as draggable inside of `absolutePanel()`/`fixedPanel()` with `draggable = TRUE`. As a result, interactions like zooming and panning now work as expected with widgets like `{plotly}` and `{leaflet}` when they appear in a draggable panel. (#3752, #3933)
-
-* For `InputBinding`s, the `.receiveMessage()` method can now be asynchronous or synchronous (previously it could only be synchronous). (#3930)
-
-## Bug fixes
-
-* `fileInput()` no longer has unwanted round corners applied to the `buttonLabel`. (#3879)
-
-* Fixed #3898: `wrapFunctionLabel()` no longer throws an error if the `name` is longer than 10000 bytes. (#3903)
-
-# shiny 1.7.5.1
-
-## Bug fixes
-
-* On r-devel (R > 4.3.1), `isTruthy(NULL)` now returns `FALSE` (as it does with older versions of R). (#3906)
-
-# shiny 1.7.5
-
-## Possibly breaking changes
-
-* For `reactiveValues()` objects, whenever the `$names()` or `$values()` methods are called, the keys are now returned in the order that they were inserted. (#3774)
-
-* The value provided to `options(shiny.json.digits)` is now interpreted as number of _digits after the decimal_ instead of _significant digits_. To treat the value as significant digits, wrap it in `I()` (e.g., `options(shiny.json.digits = I(4))`). This new default behavior not only helps with reducing digits in testing snapshots, but is also more consistent with `{jsonlite}`'s default behavior. (#3819)
-
-## New features and improvements
-
-* Closed #789: Dynamic UI is now rendered asynchronously, thanks in part to the newly exported `Shiny.renderDependenciesAsync()`, `Shiny.renderHtmlAsync()`, and `Shiny.renderContentAsync()`. Importantly, this means `<script>` tags are now loaded asynchronously (the old way used `XMLHttpRequest`, which is synchronous). In addition, `Shiny` now manages a queue of async tasks (exposed via `Shiny.shinyapp.taskQueue`) so that order of execution is preserved. (#3666)
-
-* Fixes #3840: `updateSliderInput()` now warns when attempting to set invalid `min`, `max`, or `value` values. Sending an invalid update message to an input no longer causes other update messages to fail. (#3843)
-
-* `sliderInput()` now has a larger target area for clicking or tapping on the slider handle or range. (#3859)
-
-* Closed #2956: Component authors can now prevent Shiny from creating an input binding on specific elements by adding the `data-shiny-no-bind-input` attribute to the element. The attribute may have any or no value; its presence will prevent binding. This feature is primarily useful for input component authors who want to use standard HTML input elements without causing Shiny to create an input binding for them. Additionally, Shiny now adds custom classes to its inputs. For example, `checkboxInput()` now has a `shiny-input-checkbox` class. These custom classes may be utilized in future updates to Shiny's input binding logic. (#3861)
-
-* `Map` objects are now initialized at load time instead of build time. This avoids potential problems that could arise from storing `fastmap` objects into the built Shiny package. (#3775)
-
-## Bug fixes
-
-* Fixed #3771: Sometimes the error `ion.rangeSlider.min.js: i.stopPropagation is not a function` would appear in the JavaScript console. (#3772)
-
-* Fixed #3833: When `width` is provided to `textAreaInput()`, we now correctly set the width of the `<textarea>` element. (#3838)

-#' Customize busy indicator options
-#'
-#' @description
-#' Shiny automatically includes busy indicators, which more specifically means:
-#'   1. Calculating/recalculating outputs have a spinner overlay.
-#'   2. Outputs fade out/in when recalculating.
-#'   3. When no outputs are calculating/recalculating, but Shiny is busy
-#'     doing something else (e.g., a download, side-effect, etc), a page-level
-#'     pulsing banner is shown.
-#'
-#' This function allows you to customize the appearance of these busy indicators
-#' by including the result of this function inside the app's UI. Note that,
-#' unless `spinner_selector` (or `fade_selector`) is specified, the spinner/fade
-#' customization applies to the parent element. If the customization should
-#' instead apply to the entire page, set `spinner_selector = 'html'` and
-#' `fade_selector = 'html'`.
-#'
-#' @param ... Currently ignored.
-#' @param spinner_type The type of spinner. Pre-bundled types include:
-#'   '`r paste0(.busySpinnerTypes, collapse = "', '")`'.
-#'
-#'   A path to a local SVG file can also be provided. The SVG should adhere to
-#'   the following rules:
-#'   * The SVG itself should contain the animation.
-#'   * It should avoid absolute sizes (the spinner's containing DOM element
-#'     size is set in CSS by `spinner_size`, so it should fill that container).
-#'   * It should avoid setting absolute colors (the spinner's containing DOM element
-#'     color is set in CSS by `spinner_color`, so it should inherit that color).
-#' @param spinner_color The color of the spinner. This can be any valid CSS
-#'   color. Defaults to the app's "primary" color if Bootstrap is on the page.
-#' @param spinner_size The size of the spinner. This can be any valid CSS size.
-#' @param spinner_delay The amount of time to wait before showing the spinner.
-#'   This can be any valid CSS time and can be useful for not showing the spinner
-#'   if the computation finishes quickly.
-#' @param spinner_selector A character string containing a CSS selector for
-#'   scoping the spinner customization. The default (`NULL`) will apply the
-#'   spinner customization to the parent element of the spinner.
-#' @param fade_opacity The opacity (a number between 0 and 1) for recalculating
-#'   output. Set to 1 to "disable" the fade.
-#' @param fade_selector A character string containing a CSS selector for
-#'   scoping the spinner customization. The default (`NULL`) will apply the
-#'   spinner customization to the parent element of the spinner.
-#' @param pulse_background A CSS background definition for the pulse. The
-#'   default uses a
-#'   [linear-gradient](https://developer.mozilla.org/en-US/docs/Web/CSS/gradient/linear-gradient)
-#'   of the theme's indigo, purple, and pink colors.
-#' @param pulse_height The height of the pulsing banner. This can be any valid

-#' Task or computation that proceeds in the background
-#'
-#' @description In normal Shiny reactive code, whenever an observer, calc, or
-#'   output is busy computing, it blocks the current session from receiving any
-#'   inputs or attempting to proceed with any other computation related to that
-#'   session.
-#'
-#'   The `ExtendedTask` class allows you to have an expensive operation that is
-#'   started by a reactive effect, and whose (eventual) results can be accessed
-#'   by a regular observer, calc, or output; but during the course of the
-#'   operation, the current session is completely unblocked, allowing the user
-#'   to continue using the rest of the app while the operation proceeds in the
-#'   background.
-#'
-#'   Note that each `ExtendedTask` object does not represent a _single
-#'   invocation_ of its long-running function. Rather, it's an object that is
-#'   used to invoke the function with different arguments, keeps track of
-#'   whether an invocation is in progress, and provides ways to get at the
-#'   current status or results of the operation. A single `ExtendedTask` object
-#'   does not permit overlapping invocations: if the `invoke()` method is called
-#'   before the previous `invoke()` is completed, the new invocation will not
-#'   begin until the previous invocation has completed.
-#'
-#' @section `ExtendedTask` versus asynchronous reactives:
-#'
-#'   Shiny has long supported [using
-#'   \{promises\}](https://rstudio.github.io/promises/articles/promises_06_shiny.html)
-#'   to write asynchronous observers, calcs, or outputs. You may be wondering
-#'   what the differences are between those techniques and this class.
-#'
-#'   Asynchronous observers, calcs, and outputs are not--and have never
-#'   been--designed to let a user start a long-running operation, while keeping
-#'   that very same (browser) session responsive to other interactions. Instead,
-#'   they unblock other sessions, so you can take a long-running operation that
-#'   would normally bring the entire R process to a halt and limit the blocking
-#'   to just the session that started the operation. (For more details, see the
-#'   section on ["The Flush
-#'   Cycle"](https://rstudio.github.io/promises/articles/promises_06_shiny.html#the-flush-cycle).)
-#'
-#'   `ExtendedTask`, on the other hand, invokes an asynchronous function (that
-#'   is, a function that quickly returns a promise) and allows even that very
-#'   session to immediately unblock and carry on with other user interactions.

 #' Add callbacks for Shiny session events
 #'
-#' @description
 #' These functions are for registering callbacks on Shiny session events.
-#' `onFlush` registers a function that will be called before Shiny flushes the
-#' reactive system. `onFlushed` registers a function that will be called after
-#' Shiny flushes the reactive system. `onUnhandledError` registers a function to
-#' be called when an unhandled error occurs before the session is closed.
-#' `onSessionEnded` registers a function to be called after the client has
-#' disconnected.
+#' `onFlush` registers a function that will be called before Shiny flushes
+#' the reactive system. `onFlushed` registers a function that will be
+#' called after Shiny flushes the reactive system. `onSessionEnded`
+#' registers a function to be called after the client has disconnected.
 #'
 #' These functions should be called within the application's server function.
 #'
 #' All of these functions return a function which can be called with no
 #' arguments to cancel the registration.
 #'
-#' @section Unhandled Errors:
-#' Unhandled errors are errors that aren't otherwise handled by Shiny or by the
-#' application logic. In other words, they are errors that will either cause the
-#' application to crash or will result in "Error" output in the UI.
-#'
-#' You can use `onUnhandledError()` to register a function that will be called
-#' when an unhandled error occurs. This function will be called with the error
-#' object as its first argument. If the error is fatal and will result in the
-#' session closing, the error condition will have the `shiny.error.fatal` class.
-#'
-#' Note that the `onUnhandledError()` callbacks cannot be used to prevent the
-#' app from closing or to modify the error condition. Instead, they are intended
-#' to give you an opportunity to log the error or perform other cleanup
-#' operations.
-#'
 #' @param fun A callback function.
 #' @param once Should the function be run once, and then cleared, or should it
 #'   re-run each time the event occurs. (Only for `onFlush` and
 #'   `onFlushed`.)
 #' @param session A shiny session object.

 * An attractive default look based on [Bootstrap](https://getbootstrap.com/) which can also be easily customized with the [bslib](https://github.com/rstudio/bslib) package or avoided entirely with more direct R bindings to HTML/CSS/JavaScript.
 * Seamless integration with [R Markdown](https://shiny.rstudio.com/articles/interactive-docs.html), making it easy to embed numerous applications natively within a larger dynamic document.

 For help with learning fundamental Shiny programming concepts, check out the [Mastering Shiny](https://mastering-shiny.org/) book and the [Shiny Tutorial](https://shiny.rstudio.com/tutorial/). The former is currently more up-to-date with modern Shiny features, whereas the latter takes a deeper, more visual, dive into fundamental concepts.

-This example demonstrates a core feature of Shiny: **reactivity**. In the `server` function, a reactive called `datasetInput` is declared. 
-
-Notice that the reactive expression depends on the input expression `input$dataset`, and that it's used by two output expressions: `output$summary` and `output$view`. Try changing the dataset (using *Choose a dataset*) while looking at the reactive and then at the outputs; you will see first the reactive and then its dependencies flash. 
-
-Notice also that the reactive expression doesn't just update whenever anything changes--only the inputs it depends on will trigger an update. Change the "Caption" field and notice how only the `output$caption` expression is re-evaluated; the reactive and its dependents are left alone.
